+ RFC6761: special case "localhost" (#430)
+
+ As per RFC6761 Section 6.3, "localhost" lookups need to be special cased to return loopback addresses, and not forward queries to recursive dns servers.
+
+ We first look up via files (/etc/hosts or equivalent), and if that fails, we then attempt a system-specific address enumeration for loopback addresses (currently Windows-only), and finally fallback to ::1 and 127.0.0.1.
+
+ Fix By: Brad House (@bradh352)
+ Fixes Bug: #399
+
+- [Brad House brought this change]
+
+ Reimplement ares_gethostbyname() by wrapping ares_getaddrinfo() (#428)
+
+ ares_gethostbyname() and ares_getaddrinfo() do a lot of similar things, however ares_getaddrinfo() has some desirable behaviors that should be imported into ares_gethostbyname(). For one, it sorts the address lists for the most likely to succeed based on the current system routes. Next, when AF_UNSPEC is specified, it properly handles search lists instead of first searching all of AF_INET6 then AF_INET, since ares_gethostbyname() searches in parallel. Therefore, this PR should also resolve the issues attempted in #94.
+
+ A few things this PR does:
+
+ 1. ares_parse_a_reply() and ares_parse_aaaa_reply() had very similar code to translate struct ares_addrinfo into a struct hostent as well as into struct ares_addrttl/ares_addr6ttl this has been split out into helper functions of ares__addrinfo2hostent() and ares__addrinfo2addrttl() to prevent this duplicative code.
+
+ 2. ares_getaddrinfo() was apparently never honoring HOSTALIASES, and this was discovered once ares_gethostbyname() was turned into a wrapper, the affected test cases started failing.
+
+ 3. A slight API modification to save the query hostname into struct ares_addrinfo as the last element of name. Since this is the last element, and all user-level instances of struct ares_addrinfo are allocated internally by c-ares, this is not an ABI-breaking change nor would it impact any API compatibility. This was needed since struct hostent has an h_name element.
+
+ 4. Test Framework: MockServer tests via TCP would fail if more than 1 request was received at a time which is common when ares_getaddrinfo() queries for both A and AAAA records simultaneously. Infact, this was a long standing issue in which the ares_getaddrinfo() test were bypassing TCP alltogether. This has been corrected, the message is now processed in a loop.
+
+ 5. Some tests had to be updated for overall correctness as they were invalid but somehow passing prior to this change.

+- ares_getaddrinfo(): continue to next domain in search if query returns ARES_ENODATA

+- Allow '/' as a valid character for a returned name
+
+ As of c-ares 1.17.2, a CNAME an in-addr.arpa delegation broke due

+- ares_expand_name should allow underscores (_) as SRV records legitimately use them
+
+ c-ares 1.17.2 introduced response validation to prevent a security issue, however
+ it did not have (_) listed as a valid character for domain name responses which
+ caused issues when a CNAME referenced a SRV record which contained underscores.
+
+ While RFC2181 section 11 does explicitly state not to do validation, that applies
+ to servers not clients.

+- ares_parse_ptr_reply() handle NULL for addr/addr_len. Fixes #392
+
+ NodeJS passes NULL for addr and 0 for addrlen parameters to ares_parse_ptr_reply(). On systems where malloc(0) returned NULL, this would cause the function to return ARES_ENOMEM, but the cleanup wasn't handled properly and would crash.
+
+ This patche fixes that bug, and also hardens ares_free_hostent() to not leak memory during cleanup.
+
+ Fixes: #392
+ Fix By: Brad House (@bradh352)
+
+- Define behavior of malloc(0)
+
+ Some systems may return either NULL or a valid pointer on malloc(0). c-ares should never call malloc(0) so lets return NULL so we're more likely to find an issue if it were to occur.

+- Win32: Fix tools build with autotools static library
+ When c-ares is being built as static on Win32, CARES_STATICLIB must
+ be defined, but it wasn't being pulled in for the tools.
+
+ Fixes: #384
+ Fix By: Brad House (@bradh352)
+
+- Loosen requirements for static c-ares library when building tests
+
+ It appears that when building tests, it would hardcode enabling building
+ of the c-ares static library. This was probably due to Windows limitations
+ in symbol visibility.
+
+ This change will use the static library if it exists for tests, always.
+ Otherwise, it will only forcibly enable static libraries for tests on

+
+ 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.

+
+ 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.

+
+ 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.

+ ares_parse_naptr_reply: make buffer length check more accurate
+
+ 9478908a490a6bf009ba58d81de8c1d06d50a117 introduced a length check
+ for records parsed by `ares_parse_naptr_reply()`. However, that
+ function is designed to parse replies which also contain non-NAPTR
+ records; for A records, the `rr_len > 7` check will fail as there
+ are only 4 bytes of payload.
+ In particular, parsing ANY replies for NAPTR records was broken
+ by that patch.
+
+ Fix that by moving the check into the case in which it is already
+ known that the record is a NAPTR record.

+ 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
+ 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.

+- api: add ARES_OPT_NOROTATE optmask value
+
+ Fix up a couple of problems with configuring whether c-ares rotates
+ between different name servers between requests.
+
+ Firstly, ares_save_options() returns (in *optmask) the value of
+ (channel->optmask & ARES_OPT_ROTATE), which doesn't necessarily
+ indicate whether the channel is or is not actually doing rotation.
+ This can be confusing/incorrect if:
+ - the channel was originally configured without ARES_OPT_ROTATE
+ (so it appears that the channel is not rotating)
+ - the /etc/resolv.conf file includes the 'rotate' option
+ (so the channel is actually performing rotation).
+
+ Secondly, it is not possible to reliably configure a channel
+ to not-rotate; leaving off ARES_OPT_ROTATE is not enough, since
+ a 'rotate' option in /etc/resolv.conf will turn it on again.
+
+ Therefore:
+ - add an ARES_OPT_NOROTATE optmask value to allow explicit
+ configuration of no-rotate behaviour
+ - in ares_save_options(), report the value of channel->rotate
+ as exactly one of (optmask & ARES_OPT_ROTATE) or
+ (optmask & ARES_OPT_NOROTATE).
+
+ In terms of back-compatibility:
+ - existing apps that set ARES_OPT_ROTATE will continue to rotate,
+ and to have ARES_OPT_ROTATE reported back from ares_save_options()
+ - existing apps that don't set ARES_OPT_ROTATE will continue to
+ use local config/defaults to decide whether to rotate, and will
+ now get ARES_OPT_ROTATE or ARES_OPT_NOROTATE reported back from
+ ares_save_options() rather than 0.
+
+- ares_init_options: only propagate init failures from options
+
+ Commit 46bb820be3a8 ("ares_init_options: don't lose init failure")
+ changed init behaviour so that earlier errors in initialization
+ weren't lost. In particular, if the user passes in specific
+ options but they are not applied (e.g. because of an allocation
+ failure), that failure needs to be reported back to the user; this
+ also applies when duplicating a channel with ares_dup().
+
+ However, other initialization failures can be ignored and
+ overridden -- in particular, if init_by_resolv_conf() or
+ init_by_environment() fail, then falling back to default values
+ is OK.
+
+ So only preserve failures from the init_by_options() stage, not
+ from all initialization stages.
+
+ Fixes issue 60.

+ configure: check if tests can get built before enabled
+
+ The current approach for disabling tests is not a good solution because
+ it forces you to pass --disable-tests, rather than auto-detect if your
+ system can support the tests in the first place. Many (most?) systems
+ do not have C++11. This also causes issues when chain-building c-ares,
+ the hosting system needs to be updated to support passing this
+ additional flag if necessary, it doesn't seem reasonable to add this
+ requirement which breaks compatibility.
+
+ This change auto-detects if the system can build the tests and
+ automatically disable them if it cannot. If you pass --enable-tests to
+ configure and the system cannot build them either due to lack of system
+ support, or because cross-compilation is being used, it will throw an
+ appropriate error since the user indicated they really did want the
+ tests.

+ for the same repeated request still have to use EXPECT_CALL.

+
+ Ignore `fopen` errors to use default values
+
+ After 46bb820be3a83520e70e6c5f0c5133253fcd69cd `init_by_resolv_conf`
+ errors are no longer swallowed in `ares_init_options`. This has exposed
+ a previously unknown bug in `lookups` initialization code.
+
+ If there is no lookup configuration in `resolv.conf`,
+ `init_by_resolv_conf` will attempt to read it from other files available
+ on the system. However, some of these files may have restricted
+ permissions (like `600`), which will lead to `EACCESS` errno, which in
+ turn is handled like a fatal error by `init_by_resolv_conf`.
+
+ However, it sounds illogical that this error should be handled as a
+ fatal. There is a `init_by_defaults` call that overrides `lookups` with
+ default value, and certainly possible absence of lookup information is
+ the reason why this function exists in a first place!
+
+ I suggest handling any `fopen` errors as non-fatal ones, allowing to
+ pick up the `lookups` value from different config files, or to pick up
+ default value.

+- Document callback type in man page for ares_set_socket_callback

+- test: Ignore SIGPIPE in tests
+
+- test: More initialization tests
+
+- test: Improve containerized test mechanism
+
+ Aim is to ensure that code coverage information can escape the
+ container. To do this:
+ - Enter a new mount namespace too, so that we can...
+ - Bind mount the expected source directory into the container
+ - Share memory with the sub-process so coverage information is
+ shared too.
+
+- test: Make contained tests easier to write
+
+- test: Add framework for containerized testing
+
+ On Linux we can potentially use user and UTS namespaces to run a test
+ in a pseudo-container with:
+ - arbitrary filesystem (e.g. /etc/resolv.conf, /etc/nsswitch.conf, /etc/hosts)
+ - arbitrary hostname/domainname.
+
+ Include a first pass at the framework code to allow this, along with a
+ first test case that uses the container.
+
+- test: Use a longer timeout for less flakiness
+
+ Having occasional test failures from timeout before multiple
+ queries can complete, so up the default timeout for the test
+ from 100ms to 1500ms.
+
+- test: Make failure tests more robust
+
+ Different platforms will do different numbers of allocations
+ in the processing of a given API call; just check that the
+ return code is either success or ENOMEM, and free off any
+ returned state in the former case.
+
+ Also cope with ECONNREFUSED as well as ENOTFOUND.
+
+- test: Get test code building under Windows
+
+ - Initial nmake file based off library nmake file
+ - Cast socket call arguments to (char *)
+ - Use wrapper sclose() that maps to closesocket() or close()
+ - Build a config.h indicating presence of headers
+ - Conditionally include netdb.h
+ - Remove unnecessary include of sys/socket.h

+ - Rename Process(fd) to ProcessFD(fd) to avoid confusion.
+ - Initialize channel by using the new ares_set_servers_ports()
+ entrypoint, so multiple ports on the same loopback address
+ can be used.
+
+- test: Update test for set/get_servers variants

+
+ Also make it generally available.

+
+ Also expand and re-order the setting of environment variables
+ for easier modification.
+
+ test: Add LSAN build to Travis config
+
+- test: Add initial unit tests for c-ares library
+
+ The tests are written in C++11, using the GoogleTest and GoogleMock
+ frameworks. They have their own independent autoconf setup, so that
+ users of the library need not have a C++ compiler just to get c-ares
+ working (however, the test/configure.ac file does assume the use of
+ a shared top-level m4/ directory). However, this autoconf setup has
+ only been tested on Linux and OSX so far.
+
+ Run with "./arestest", or "./arestest -v" to see extra debug info.
+ The GoogleTest options for running specific tests are also
+ available (e.g. "./arestest --gtest_filter=*Live*").
+
+ The tests are nowhere near complete yet (currently hitting around
+ 60% coverage as reported by gcov), but they do include examples
+ of a few different styles of testing:
+
+ - There are live tests (ares-test-live.cc), which assume that the
+ current machine has a valid DNS setup and connection to the
+ internet; these tests issue queries for real domains but don't
+ particularly check what gets returned. The tests will fail on
+ an offline machine.
+
+ - There a few mock tests (ares-test-mock.cc) that set up a fake DNS
+ server and inject its port into the c-ares library configuration.
+ These tests allow specific response messages to be crafted and
+ injected, and so are likely to be used for many more tests in
+ future.
+
+ - To make this generation/injection easier, the dns-proto.h file
+ includes C++ helper classes for building DNS packets.
+
+ - Other library entrypoints that don't require network activity
+ (e.g. ares_parse_*_reply) are tested directly.
+
+ - There are few tests of library-internal functions that are not
+ normally visible to API users (in ares-test-internal.cc).
+
+ - A couple of the tests use a helper method of the test fixture to
+ inject memory allocation failures, using the earlier change to the
+ library to allow override of malloc/realloc/free.
+
+ - There is also an entrypoint to allow Clang's libfuzzer to drive
+ the packet parsing code in ares_parse_*_reply, together with a
+ standalone wrapper for it (./aresfuzz) to allow use of afl-fuzz
+ for further fuzz testing.
+

+- build: Allow header compilation by Windows C++ compiler
+
+- build: Expose whether symbol hiding is on
+
+ Adding the CARES_SYMBOL_HIDING definition allows the test suite to
+ detect whether internal symbols are available or not.
+
+- build: Add autoconf macros for C++11 code using pthreads
+
+ Pull in testing macros from the GNU autoconf archive to allow
+ configure scripts to test for and setup use of a C++11 compiler
+ (AX_CXX_COMPILE_STDCXX_11) and the pthreads library (AX_PTHREAD).
+
+ Note that these macros are not used by the main library autoconf,
+ just by the tests (which share the same m4/ directory).
+
+- build: Add a code coverage option
+
+ Configure with:
+ ./configure --enable-code-coverage
+ Show coverage output with:
+ make code-coverage-capture
+
+ Built on m4/ax_code_coverage.m4 from the GNU autoconf archive
+ to provide the macros to check for presence of gcov + lcov;
+ upstream macro modified to:
+ - Remove use of $(AM_DEFAULT_VERBOSITY) , as earlier versions of
+ autoconf (such as the one used by default on Travis) do not have this.
+ - Rather than automatically defining CODE_COVERAGE_RULES to be a set
+ of makefile rules that use ifeq/endif (which is GNU make-specific),
+ instead only define CODE_COVERAGE_RULES if coverages is turned on,
+ and in that case don't use conditionals in the makefile.
+
+- api: Add entrypoints to allow use of per-server ports
+
+ Add user-visible entrypoints ares_{get,set}_servers_ports(3), which
+ take struct ares_addr_port_node rather than struct ares_addr_node.
+ This structure includes a UDP and TCP port number; if this is set
+ to zero, the channel-wide port values are used as before.
+
+ Similarly, add a new ares_set_servers_ports_csv(3) entrypoint, which
+ is analogous to ares_set_servers(3) except it doesn't ignore any
+ specified port information; instead, any per-server specified port
+ is used as both the UDP and TCP port for that server.
+
+ The internal struct ares_addr is extended to hold the UDP/TCP ports,
+ stored in network order, with the convention that a value of zero
+ indicates that the channel-wide UDP/TCP port should be used.
+
+ For the internal implementation of ares_dup(3), shift to use the
+ _ports() version of the get/set functions, so port information is
+ transferred correctly to the new channel.
+
+ Update manpages, and add missing ares_set_servers_csv to the lists
+ while we're at it
+
+- api: Add ares_set_sortlist(3) entrypoint
+
+ Allow explicit configuration of the channel's sortlist, by
+ specifying a string in the same format as the equivalent
+ /etc/resolv.conf option.
+
+ This allows library users to perform the same configuration
+ that is available via /etc/resolv.conf, but without needing
+ to change that file.
+
+- api: Allow injection of user-specified malloc/free functions
+
+ Add a new ares_library_init_mem() initialization function for the
+ library which allows the library user to specify their own malloc,
+ realloc & free equivalents for use library-wide.
+
+ Store these function pointers in library-wide global variables,
+ defaulting to libc's malloc(), realloc() and free().
+
+ Change all calls to malloc, realloc and free to use the function pointer
+ instead. Also ensure that ares_strdup() is always available
+ (even if the local environment includes strdup(3)), and change the
+ library code to always use it.
+
+ Convert calls to calloc() to use ares_malloc() + memset
+
+- api: Add option to expose some internal functions
+
+ Purely for testing, add --enable-expose-statics option to configure
+ which converts some static internal functions to be externally visible.
+
+- api: Expose the ares_library_initialized() function
+
+- ahost: Allow repeated -s options
+
+ This also removes a potential leak where later -s options would
+ replace earlier ones without freeing the relevant string.
+
+- Mark unhittable lines
+
+ Add comments for the benefit of the lcov tool, marking
+ lines that cannot be hit. Typically these are fall-back
+ protection arms that are already covered by earlier checks,
+ and so it's not worth taking out the unhittable code (in case
+ someone changes the code between the two places in future).
+
+- ares_set_servers_csv.3: make return type match code
+
+- bitncmp: update comment to match code behaviour
+
+- ares_striendstr: fix so non-NULL return can happen
+
+ This looks to have been broken since it was first introduced in 2005 in
+ commit aba0b775ea30 ("Added ares_getnameinfo which mimics the
+ getnameinfo API")
+
+- config_sortlist: free any existing sortlist on (re)alloc failure
+
+ If we get an allocation failure on 2nd or later entry in the sortlist, the
+ code would return ENOMEM but still leave the initial entries allocated.
+ Ensure that *sortlist is set to NULL whenever ENOMEM is returned.
+
+- ares_dup: clear new channel on failure
+
+ If the attempt to transfer IPv6 servers from the old to the new channel
+ fails, the previous code would still return a channel to the user even though
+ an error return code was generated. This makes it likely that users would
+ leak the channel, so explicitly clear the channel in this case.
+
+- ares_init_options: don't lose init failure
+
+ If (say) init_by_options() fails, the subsequent call to
+ init_by_defaults() was overwriting the return code with
+ success. Still call init_by_defaults() regardless, but track
+ its return value separately
+
+- ares_gethostbyname: don't leak valid-but-empty hostent
+
+ If an AF_UNSPEC query gets a valid response to its AAAA query,
+ but which has no IPv6 addresses in it, then the code chains on to
+ a A record query. However, the hostent from the AAAA response
+ was being leaked along the way (because it gets replaced before
+ the follow-on end_hquery() invocation).
+
+- ares_parse_txt_reply: propagate errors from per-substring loop
+
+ If we get an allocation failure when processing a particular substring in a
+ TXT record, that failure is silently lost; fix that by propagating errors from
+ the inner loop to the outer loop.
+
+- process_answer: fix things up correctly when removing EDNS option
+
+ When a server rejects an EDNS-equipped request, we retry without
+ the EDNS option. However, in TCP mode, the 2-byte length prefix was
+ being calculated wrong -- it was built from the answer length rather than
+ the length of the original request.
+
+ Also, it is theoretically possible that the call to realloc() might change
+ the data pointed to; to allow for this, qbuf also needs updating.
+
+ (Both these fixes were actually included in a patchset sent on the mailing
+ list in Oct 2012, but were included with other functional changes that
+ didn't get merged:
+ http://c-ares.haxx.se/mail/c-ares-archive-2012-10/0004.shtml)
+
+- ares__read_line: clear buf pointer on realloc failure
+
+- ares_expand_name: check for valid bits in label length
+
+ The top two bits of the label length indicate whether this is a
+ label length (00) or an index to a name elsewhere in the message
+ (11). RFC1035 4.1.4 says that the other possible values for the
+ top two bits (01, 10) are reserved for future use.

+ ares_build.h: fix building on 64-bit powerpc
+
+ There are two issues.

+ 2. clang defines __GNU__ and defines both __ppc64__ and __ppc__ when

+ * The 'NTDDI_VERSION' needs to be raised to 0x05010000

+ target to be consistent with e.g. Makefile.msvc etc.
+ * 'ENABLE_IPV6' is no longer used. Hence removed the '%use_ipv6' construct.
+ * object-file order seems to be important (Watcom v.19). Hence
+ 'ares_getopt.obj' must be put after the .obj that references getopt().

+- ares_reinit()
+
+ - To allow an app to force a re-read of /etc/resolv.conf etc, pretty much
+ like the res_init() resolver function offers
+
+- - Tommie Gannert pointed out a silly bug in ares_process_fd() since it didn't
+ check for broken connections like ares_process() did. Based on that, I
+ merged the two functions into a single generic one with two front-ends.
+
+Yang Tse (30 Dec 2009)
+- VMS specific preprocessor symbol checking adjustments
+
+- Mention last changes
+
+- - Fix configure_socket() to use ares_socket_t instead of int data type.
+
+- - Where run-time error checks enabling compiler option /GZ was used it is now
+ replaced with equivalent /RTCsu for Visual Studio 2003 and newer versions.
+
+ - Compiler option /GX is now replaced with equivalent /EHsc for all versions.
+
+- - Ingmar Runge noticed that Windows config-win32.h configuration file
+ did not include a definition for HAVE_CLOSESOCKET which resulted in
+ function close() being inappropriately used to close sockets.
+
+Daniel Stenberg (30 Nov 2009)
+- start working on 1.7.1
+
+Version 1.7.0 (27 Nov 2009)
+
+Yang Tse (27 Nov 2009)
+- Preserve empty line following last target
+
+- - Larry Lansing fixed ares_parse_srv_reply to properly parse replies
+ which might contain non-SRV answers, skipping over potential non-SRV
+ ones such as CNAMEs.
+
+- When using icc, compile with -fpic and link with intel dynamic libraries.
+
+- Added 'currently' in italics to insist on transient situation.
+
+- Fix language
+
+- Daniel wants upcoming release to be 1.7.0
+
+- Mention last changes
+
+- - Removed from external interface preprocessor symbol definition for
+ CARES_HAVE_ARES_FREE_DATA. Current functionality of ares_free_data()
+ makes it unnecessary.
+
+- Added README.msvc
+
+- Changed c-ares naming conventions when using MSVC as described in README.msvc
+
+- - Mention other recent changes
+
+- - Jakub Hrozek renamed addrttl and addr6ttl structs to ares_addrttl and
+ ares_addr6ttl in order to prevent name space pollution, along with
+ necessary changes to code base and man pages.This change does not break
+ ABI, there is no need to recompile existing applications. But existing
+ applications using these structs with the old name will need source code
+ adjustments when recompiled using c-ares 1.6.1.
+
+- - Jakub Hrozek fixed more function prototypes in man pages to sync them
+ with the ones declared in ares.h
+
+- Make configure remove the ares_build.h file included in distribution tarballs.
+
+- Fix macro redefinition.
+
+- Fix name space pollution.
+
+- Allow using different extra import libraries for debug and release builds.
+
+- Add manifest stuff to msvc makefile
+
+- Sync man page with reality
+
+- Add missing external API decoration for ares_set_socket_callback()
+
+- Add ares_free_data() man page.
+
+- - Provide in external interface preprocessor symbol definitions for
+ CARES_HAVE_ARES_FREE_DATA as an indication of function availability.
+
+- Remove typecast
+
+- Fix comment
+
+- Add ares_data.c and ares_data.h
+
+- Jakub Hrozek modified ares_parse_srv_reply() and ares_parse_txt_reply() API
+ to return a linked lists of results. These were also modified to internally
+ use the ares_data memory struct and as such its result must be free'ed with
+ ares_free_data().
+
+- Initial support for the generic ares_free_data() function that will allow
+ applications to free memory allocated and returned by some c-ares funtions.
+
+- Make usage of calloc()'s arguments consistent with rest of code base
+
+- workaround icc 9.1 optimizer issue
+
+- Add icc fvisibility bug test
+
+- Fix icc 9.0 compiler warning: external definition with no prior declaration
+
+- Fix three var names
+
+- Add check for assert.h header file
+
+- getaddrinfo is fully thread safe on solaris versions which
+ implement the function even when h_errno is not a macro.
+
+ The h_errno macro test now only done on systems for which there
+ is no hard coded knowledge about getaddrinfo's thread safeness.
+
+- Remove files generated on previous buildconf/configure run
+
+- Remove enable-thread / disable-thread configure option. These were only placebo
+ options. The library is always built as thread safe as possible on every system.
+
+- Refactor how preprocessor symbol _THREAD_SAFE definition is done.
+
+- Assume that getaddrinfo is thread safe, unless hard coded
+ knowledge says the contrary or h_errno is not defined.
+
+- Related with the threadsafe capability of getaddrinfo:
+
+ - Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2
+ and newer have a threadsafe getaddrinfo.
+
+ - Fix Dragonfly BSD triplet detection.
+
+ - In case the hard-coded knowledge says that getaddrinfo is threadsafe,
+ an additional check is done to verify that h_errno is also defined.
+ If h_errno isn't defined, we finally assume that it isn't threadsafe.
+ Jamie Lokier provided the inspiration for this extra check.
+
+- AIX 5.2 and newer have threadsafe getaddrinfo.
+
+ Add some comments to better understand what the regex's pretend to achieve.
+
+- HP-UX 11.11 and later have threadsafe getaddrinfo
+
+- Check if getaddrinfo is threadsafe when function check allows it to be used
+
+- Renamed fpGetNetworkParams and fpSystemFunction036 to avoid namespace pollution with static library
+
+- Add kernel32.lib
+
+- Mention last changes
+
+- Reinstate copyright symbol lost in previous commit
+
+- Make some strings different in resource file for debug or release builds
+
+- Ignore more subdirs
+
+- Fix compiler warning: conditional expression is constant
+
+- Sync linker and resource compiler options with Makefile.msvc
+
+- Follow Makefile.msvc subdirectory naming scheme, and sync compiler options
+
+- Updated MSVC makefile that allows building dynamic and static
+ c-ares libraries in debug and release flavours.
+
+ Additionally each of the three sample programs is built against
+ each of the four possible c-ares libraries, generating all this
+ a total number of 12 executables and 4 libraries.
+
+- Test for USE_WINSOCK since it is more restrictive than WIN32
+
+- Make header inclusion depend on HAVE_*_H definition
+
+- Remove unneeded preprocessor directives
+
+- Adjust c-ares include paths for memory tracking enabled (--enable-curldebug) builds
+
+- source files used by sample programs
+
+- Renamed c-ares setup.h to ares_setup.h
+
+- Adjust include paths to take in account that currently:
+
+ c-ares with --enable-curldebug uses memdebug.h from libcurl's lib subdirectory.
+
+ memdebug.h needs access to libcurl's setup.h from libcurl's lib subdirectory
+ and also needs access to libcurl's generated curl_config.h

+
+ 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 rather than an official
+release tarball, see the [GIT-INFO](GIT-INFO) file in the root directory
+for specific instructions on how to proceed.
+
+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
+the same for both Git and official release tarballs.
+
+AutoTools Build
+===============
+
+### General Information, works on most Unix Platforms (Linux, FreeBSD, etc)
+
+A normal Unix installation is made in three or four steps (after you've
+unpacked the source archive):
+
+ ./configure
+ make
+ 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](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="$WATCOM/binl/wstrip" CFLAGS=-Wextra
+
+
+### CROSS COMPILE
+
+(This section was graciously brought to us by Jim Duey, with additions by
+Dan Fandrich)
+
+Download and unpack the c-ares package.
+
+`cd` to the new directory. (e.g. `cd c-ares-1.7.6`)
+
+Set environment variables to point to the cross-compile toolchain and call
+configure with any options you need. Be sure and specify the `--host` and
+`--build` parameters at configuration time. The following script is an
+example of cross-compiling for the IBM 405GP PowerPC processor using the
+toolchain from MonteVista for Hardhat Linux.
+
+```sh
+#! /bin/sh
+
+export PATH=$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
+```
+
+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
+
+
+### Cygwin (Windows)
+
+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`
+
+
+### 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`.
+
+
+### 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:$PATH
+ ./configure --host=arm-linux-androideabi [more configure options]
+ make
+ ```
+ - if you want to compile directly from our GIT repo you might run into
+ this issue with older automake stuff:
+
+ ```
+ checking host system type...
+ Invalid configuration `arm-linux-androideabi':
+ system `androideabi' not recognized
+ configure: error: /bin/sh ./config.sub arm-linux-androideabi failed
+ ```
+ this issue can be fixed with using more recent versions of `config.sub`
+ and `config.guess` which can be obtained here:
+ http://git.savannah.gnu.org/gitweb/?p=config.git;a=tree
+ you need to replace your system-own versions which usually can be
+ found in your automake folder:
+ `find /usr -name config.sub`
+
+
+CMake builds
+============
+
+Current releases of c-ares introduce a CMake v3+ build system that has been
+tested on most platforms including Windows, Linux, FreeBSD, MacOS, AIX and
+Solaris.
+
+In the most basic form, building with CMake might look like:
+
+```sh
+cd /path/to/cmake/source
+mkdir build
+cd build
+cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local/cares ..
+make
+sudo make install
+```
+
+Options
+-------
+
+Options to CMake are passed on the command line using "-D${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
+make install
+```
+
+
+Platform-specific build systems
+===============================
+
+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](http://support.microsoft.com/kb/94248/en-us) - How To Use the C Run-Time
+
+ - [KB140584](http://support.microsoft.com/kb/140584/en-us) - How to link with the correct C Run-Time (CRT) library
+
+ - [KB190799](http://msdn.microsoft.com/en-us/library/ms235460) - Potential Errors Passing CRT Objects Across DLL Boundaries
+
+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.
+
+
+### 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](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`.
+
+
+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;
+
+

-c-ares version 1.17.2
+c-ares version 1.18.1
+
+This is an urgent bugfix release for a regression made in 1.18.0.
+
+Bug fixes:
+ o ares_getaddrinfo() would return ai_addrlen of 16 for ipv6
+ adddresses rather than the sizeof(struct sockaddr_in6)
-This is a security and bugfix release. It addresses a few security related
-issues along with various bugfixes mostly related to portability.
-Security:
- o NodeJS passes NULL for addr and 0 for addrlen to ares_parse_ptr_reply() on
- systems where malloc(0) returns NULL. This would cause a crash. [8]
- o When building c-ares with CMake, the RANDOM_FILE would not be set and
- therefore downgrade to the less secure random number generator [12]
- o If ares_getaddrinfo() was terminated by an ares_destroy(), it would cause
- a crash [13]
- o Crash in sortaddrinfo() if the list size equals 0 due to an unexpected
- DNS response [14]
- o Expand number of escaped characters in DNS replies as per RFC1035 5.1 to
- prevent spoofing [16], [17]
- o Perform validation on hostnames to prevent possible XSS due to applications
- not performing valiation themselves [18]
+
+c-ares version 1.18.0
+
+This is a feature and bugfix release. It addresses a couple of new feature
+requests as well as a couple of bug fixes.
Changes:
- o Use non-blocking /dev/urandom for random data to prevent early startup
- performance issues [5]
- o z/OS port [6]
- o ares_malloc(0) is now defined behavior (returns NULL) rather than
- system-specific to catch edge cases [7]
+ o Add support for URI(Uniform Resource Identifier) records via
+ ares_parse_uri_reply() [1]
+ o Provide ares_nameser.h as a public interface as needed by NodeJS [5]
+ o Update URLs from c-ares.haxx.se to c-ares.org [9]
+ o During a domain search, treat ARES_ENODATA as ARES_NXDOMAIN so that the
+ search process will continue to the next domain in the search. [11]
+ o Turn ares_gethostbyname() into a wrapper for ares_getaddrinfo() as they
+ followed very similar code paths and ares_gethostbyaddr() has some more
+ desirable features such as priority sorting and parallel queries for
+ AF_UNSPEC. [12]
+ o ares_getaddrinfo() now contains a name element in the address info
+ structure as the last element. This is not an API or ABI break due to
+ the structure always being internally allocated and it being the last
+ element. [12]
+ o ares_parse_a_reply() and ares_parse_aaaa_reply() were nearly identical, those
+ now use the same helper functions for parsing rather than having their own
+ code. [12]
+ o RFC6761 Section 6.3 says "localhost" lookups need to be special cased to
+ return loopback addresses, and not forward queries to recursive dns servers.
+ On Windows this now returns all loopback addresses, on other systems it
+ returns 127.0.0.1 or ::1 always, and will never forward a request for
+ "localhost" to outside DNS servers. [13]
+ o Haiki: port [14]
Bug fixes:
- o Fuzz testing files were not distributed with official archives [1]
- o Building tests should not force building of static libraries except on
- Windows [2]
- o Windows builds of the tools would fail if built as static due to a missing
- CARES_STATICLIB definition [3]
- o Relative headers must use double quotes to prevent pulling in a system
- library [4]
- o Fix OpenBSD building by implementing portability updates for including
- arpa/nameser.h [9]
- o Fix building out-of-tree for autotools [10]
- o Make install on MacOS/iOS with CMake was missing the bundle destination so
- libraries weren't actually installed [11]
- o Fix retrieving DNS server configuration on MacOS and iOS if the configuration
- did not include search domains [15]
- o ares_parse_a_reply and ares_parse_aaa_reply were erroneously using strdup()
- instead of ares_strdup() [19]
-
+ o add build to .gitignore [2]
+ o z/OS minor update, add missing semicolon in ares_init.c [3]
+ o Fix building when latest ax_code_coverage.m4 is imported [4]
+ o Work around autotools 'error: too many loops' and other newer autotools
+ import related bugs.
+ o MinGW cross builds need advapi32 link as lower case [6]
+ o Cygwin build fix due to containing both socket.h and winsock2.h [7]
+ o ares_expand_name should allow underscores (_) as SRV records legitimately use
+ them [8]
+ o Allow '/' as a valid character for a returned name for CNAME in-addr.arpa
+ delegation [10]
+ o ares_getaddrinfo() was not honoring HOSTALIASES [12]
+ o ares_getaddrinfo() had some test cases disabled due to a bug in the test
+ framework itself which has now been resolved [12]
+ o Due to Travis-CI becoming unfriendly to open-source, Cirrus-CI has now been
+ brought online for automated unit testing.

+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.org/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.
+#

+# AM_PROG_INSTALL_STRIP
+# ---------------------
+# One issue with vendor 'install' (even GNU) is that you can't
+# specify the program used to strip binaries. This is especially
+# annoying in cross-compiling environments, where the build's strip
+# is unlikely to handle the host's binaries.
+# Fortunately install-sh will honor a STRIPPROG variable, so we
+# always use install-sh in "make install-strip", and initialize
+# STRIPPROG with the value of the STRIP variable (set by the user).
+AC_DEFUN([AM_PROG_INSTALL_STRIP],
+[AC_REQUIRE([AM_PROG_INSTALL_SH])dnl
+# Installed binaries are usually stripped using 'strip' when the user
+# run "make install-strip". However 'strip' might not be the right
+# tool to use in cross-compilation environments, therefore Automake
+# will honor the 'STRIP' environment variable to overrule this program.
+dnl Don't test for $cross_compiling = yes, because it might be 'maybe'.

+\`configure' configures c-ares 1.18.1 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]

+ LIBS libraries to pass to the linker, e.g. -l
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
+ you have headers in a nonstandard directory
+ 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.
