86 getdns is a [modern asynchronous DNS API](http://www.vpnc.org/getdns-api/) intended to make all types of DNS information easily available as described by Paul Hoffman. This implementation is licensed under the New BSD License (BSD-new).
97
2422 * Document code using doxygen
2523 * Leverage github as much as possible for project coordination
2624 * Coding style/standards follow the BSD coding style <ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-current/src/share/misc/style>
27 * Follow the git flow branching model described at <http://nvie.com/posts/a-successful-git-branching-model/>
28 ** the master branch is always in a production ready state
29 ** the develop branch contains the latest development changes which are merged from develop into master once they are considered production ready
3025
3126 Non-goals (things we will not be doing at least initially) include:
3227 * implementation of the traditional DNS related routines (gethostbyname, etc.)

7772 ## Extensions / Event loop dependencies
7873
79 The implementation works with a variety of event loops, each built as a separate shared library. See [the wiki](https://github.com/verisign/getdns/wiki/Asynchronous-Support#wiki-included-event-loop-integrations) for more details.

127 .HP 3
128 .I context
129 .RP
130 Used to return the pointer to an opaque structure. The caller passes the address of a pointer (decl: getdns_context *context; passed as &context) which will be populated as a result of returning from the function. The result is a newly allocated and initialized context (if there are no errors). In the getdns_destroy_context function this is the context whose associated memory will be released.
131
132 .HP 3
133 .I set_from_os
134 .RP
135 If set_from_os is 0 then the caller must provide forwarding name servers if running in stub mode. If set_from_os is 1 then the system files are used to initialize the context. /etc/resolv.conf is used to populate forwarders when running as a stub resolver (only "nameserver" lines are recognized). If set_from_os is 1 /etc/hosts entries are preferred before resorting to a DNS query. Errors in the system files will not prevent the context form being constructed.

137168
138169 .LP
139170 When the context is used in the API for the first time and set_from_os is 1, the API starts replacing some of the values with values from the OS, such as those that would be found in res_query(3), /etc/resolv.conf, and so on, then proceeds with the new function. Some advanced users will not want the API to change the values to the OS's defaults; if set_from_os is 0, the API will not do any updates to the initial values based on changes in the OS. For example, this might be useful if the API is acting as a stub resolver that is using a specific upstream recursive resolver chosen by the application, not the one that might come back from DHCP.
140
141 .HP 3
142 .I context
143 .RP

105 The call to getdns_context_create immediately returns a context that can be
106 used with other API calls; that context contains the API's default values. Most
107 applications will want set_from_os set to true.

120 When getdns_context_destroy() returns, the application knows that all
121 outstanding transactions associated with this context will have been called;
122 callbacks that had not been called before getdns_context_destroy() was called
123 will be called with a callback_type of GETDNS_CALLBACK_CANCEL.
124 getdns_context_destroy() returns after all of the needed cleanup is done and
125 callbacks are made.

127 .SH DESCRIPTION (LONG)
128
129 .LP
130 Many calls in the DNS API require a DNS context. A DNS context contains the information that the API needs in order to process DNS calls, such as the locations of upstream DNS servers, DNSSEC trust anchors, and so on. The internal structure of the DNS context is opaque, and might be different on each OS. When a context is passed to any function, it must be an allocated context; the context must not be NULL.
131
132 .LP
133 A typical application using this API doesn't need to know anything about contexts. Basically, the application creates a default context, uses it in the functions that require a context, and then deallocates it when done. Context manipulation is available for more DNS-aware programs, but is unlikely to be of interest to applications that just want the results of lookups for A, AAAA, SRV, and PTR records.
134
135 .LP
136 It is expected that contexts in implementations of the API will not necessarily be thread-safe, but they will not be thread-hostile. A context should not be used by multiple threads: create a new context for use on a different thread. It is just fine for an application to have many contexts, and some DNS-heavy applications will certainly want to have many even if the application uses a single thread.
137
138 .LP
139 When the context is used in the API for the first time and set_from_os is 1, the API starts replacing some of the values with values from the OS, such as those that would be found in res_query(3), /etc/resolv.conf, and so on, then proceeds with the new function. Some advanced users will not want the API to change the values to the OS's defaults; if set_from_os is 0, the API will not do any updates to the initial values based on changes in the OS. For example, this might be useful if the API is acting as a stub resolver that is using a specific upstream recursive resolver chosen by the application, not the one that might come back from DHCP.
140
141 .HP 3
142 .I context
143 .RP
144 In calls to the getdns_create_context functions this parameter is used to return a newly allocated and initialized context (if there are no errors). In the getdns_destroy_context function this is the context whose associated memory will be released.
145
146 .HP 3
147 .I set_from_os
148 .RP
149 If set_from_os is 0 then the caller must provide forwarding name servers if running in stub mode. If set_from_os is 1 then the system files are used to initialize the context. /etc/resolv.conf is used to populate forwarders when running as a stub resolver (only "nameserver" lines are recognized). If set_from_os is 1 /etc/hosts entries are preferred before resorting to a DNS query. Errors in the system files will not prevent the context form being constructed.
150
151 .HP 3
152 .I userarg

154 In the extended use case this argument is passed unchanged to each of the memory management functions each time they are called.

157 .I malloc
158 .RP
159 The function that will be used for creating response dicts (and the members within the response dicts). By default the system malloc is used.

91 The getdns specification emphasizes the asynchronous nature of the API and
92 allows implementations to define their own approach. This page documents this
93 implementation's decisions and facilities provided to the developer.
94

96 This implementation provides asynchronous support via the following mechanisms:

114
115 .SS "File Descriptor Polling"
116
117 A common approach used in asynchronous applications is to poll a file
118 descriptor via system calls like select and poll and then yielding CPU when
119 ready. The API provides the following functions to support this approach:
120
121 .HP 3
122 int getdns_context_fd(getdns_context* context)
123
124 Get the file descriptor to poll for a given context. Callers should never read from this result. It is meant strictly for polling.Returns -1 if the context is NULL.
125
126 .HP 3
127 uint32_t getdns_context_get_num_pending_requests(getdns_context* context, struct timeval* next_timeout)
128
129 Get the number of outstanding asynchronous requests for a given context as well as the the amount of time until the next timeout. The next_timeout struct can be NULL. If supplied and the number of outstanding requests is > 0, then the timeout represents the relative time until the next timeout.
130
131 .HP 3
132 getdns_return_t getdns_context_process_async(getdns_context* context)
133
134 Inform the context to process its outstanding requests. Users should call this when either a timeout has occurred or the file descriptor signals that it is ready. User callbacks are fired during this call.
135
136 .SS "Example Event Loop"
137
138 The following is an example event loop leveraging select:
139
140 .Bd -literal -compact
141 struct timeval tv;
142 /* Keep looping while there are outstanding requests */
143 while (getdns_context_get_num_pending_requests(context, &tv) > 0)
144 {
145 /* setup the read FD_SET to pass to select */
146 int fd = getdns_context_fd(context);
147 fd_set read_fds;
148 FD_ZERO(&read_fds);
149 FD_SET(fd, &read_fds);
150 /* Wait on the FD or for a timeout */
151 select(fd + 1, &read_fds, NULL, NULL, &tv);
152 getdns_context_process_async(context);
153 }

156 .SS "Included Event Loop Integrations"
157
158 .LP
159 A number of applications achieve asynchronous behavior by leveraging event loop abstraction libraries. If the build system discovers a supported event loop, the event loop extension is built in addition to the getdns library. Extensions are built as an additional shared library. The following event loop libraries are supported:
160
161 .B
162 libevent1 and libevent2
163
164 .LP
165 The libevent extension allows a context to attach to a event_base. The event loop is then run like any other application using libevent via event_base_dispatch or event_base_loop and expect getdns callbacks to fire.
166
167 .LP
168 Note that if both libevent1 and libevent2 reside on system, the extension uses libevent2.

202 .LP
203 The event loop integrations documented above all leverage the same event loop extension API provided by this library. The mechanism is exposed to developers who wish to integrate their own event loop. And includes the following functions and structures:
204
205 .LP
206 The application provides a callback to indicate that a timeout has occurred.
207
208 .IP
209 typedef void (*getdns_timeout_callback) (void* userarg);
210
211 .LP
212 Timeout data provided when scheduling a timeout is captured in this structure:
213
214 .Bd -literal -compact
215 typedef struct getdns_timeout_data {
216 /* a timeout id */
217 getdns_transaction_t transaction_id;
218 /* absolute time of the timeout */
219 struct timeval timeout_time;
220 /* the timeout callback to fire */
221 getdns_timeout_callback callback;
222 /* user arg to callback */
223 void* userarg;
224 /* pointer to the underlying extension pointer that the extension will create and free */
225 void* extension_timer;
226 struct getdns_context* context;
227 } getdns_timeout_data_t;
228 .Ed
229
230 .LP
231 The application calls the extension to schedule a timer. Any timer data that needs to be tracked should be stored in eventloop_timer.
232
233 .IP
234 typedef getdns_return_t (*getdns_eventloop_schedule_timeout_t)(struct getdns_context* context,

236 getdns_timeout_data_t* timeout_data,
237 void** eventloop_timer);
238
239 .LP
240 The application calls the extension to free a timer. The timer passed in is the same as that returned in the schedule timeout. This is the only place where it is safe to free timer data. Extensions can expect this will be called for every schedule_timeout call.
241
242 .IP
243 typedef getdns_return_t (*getdns_eventloop_clear_timeout_t)(struct getdns_context* context,
244 void* eventloop_data, void* eventloop_timer);

247 The application informs the extension that the number of outbound requests has changed. This is called when an asynchronous request is submitted or canceled by the user.
248

5376 - Unescaped double quotes are removed from the input. Their only effect is
5377 that within double quotes, space and tab are treated like normal
5378 characters.
5379 - Backslashes not followed by double quotes are not special.
5380 - But 2*n+1 backslashes followed by a double quote become
5381 n backslashes followed by a double quote (n >= 0):

11 # These exist entirely to fool aclocal when bootstrapping libtool.
12 #
13 # In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
14 # which have later been changed to m4_define as they aren't part of the
15 # exported API, or moved to Autoconf or Automake where they belong.
16 #
17 # The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
18 # in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
19 # using a macro with the same name in our local m4/libtool.m4 it'll
20 # pull the old libtool.m4 in (it doesn't see our shiny new m4_define
21 # and doesn't know about Autoconf macros at all.)
22 #
23 # So we provide this file, which has a silly filename so it's always
24 # included after everything else. This provides aclocal with the
25 # AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
26 # because those macros already exist, or will be overwritten later.
27 # We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
28 #
29 # Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
30 # Yes, that means every name once taken will need to remain here until
31 # we give up compatibility with versions before 1.7, at which point
32 # we need to keep only those names which we still refer to.
33
34 # This is to help aclocal find these macros, as it can't see m4_define.

0 proposed getdns cache design
1 Glen Wiley <gwiley@verisign.com>
2
3 API Description Requirements
4 ============================
5 Considerations regarding cache are slightly different depending on
6 whether we are operating as a stub resolver or a recursive resolver.
7 The API description requires that we operate as a recursive resolver
8 and considers stub resolver behavior optional.
9
10 Recursive Resolver Cache
11 ========================
12 Caching is arguably an important feature for most recursive resolvers.
13 In this case we are not intending a replacement for the fully
14 functional recursive resolvers already available (BIND, Unbound, etc.)
15 so we shoudl limit a cache implementation to behaviors important to
16 proper operation of a recursive resolver.
17
18 DNSSEC validation can potentially triggers more queries than a simple
19 request for a A RR so I think it makes sense to cache root and TLD
20 data. Once we have gone that far it isn't much of a reach to cache
21 at each layer in the hierarchy (depth will not increase the coding
22 effort or defect rates).
23
24 Bear in mind that this resolver will only answer local processes,
25 it is not listening for queries over the network.
26
27 Stub Resolver Cache
28 ===================
29 One well supported poition is that a stub resolver should not cache
30 DNS replies as it relies on a proximate recursive resolver for
31 iterative resolution and caching. DNSSEC validation introduces
32 a potential use case for caching even when we would prefer to not
33 cache DNS replies in the stub resolver. I'd like to avoid a
34 religious debate about whether a stub resolver should have a cache
35 and focus on what we need to make the getdns API best suited to
36 its intended focus.
37
38 Since a cache makes sense for a recursive resolver we will need
39 to implement it anyway. With that in mind I recommend that we
40 use a configuration setting to enable caching and control its
41 behavior when running as a stub resolver.
42
43 Cache Design Points
44 ===================
45 If we assume that we need a cache implementation (which I concede is
46 not yet decided) then I would recommend the following design points:
47
48 Local configuration via API or local file (e.g. /etc/getdns.conf, ~/.getdnsrc)
49 - turn cache on/off
50 - turn negative cache on/off
51 - use a per user cache vs. system wide cache
52 - max TTL/TTL override (separate for pos/neg cache entries)
53 - inclusions (use cache for specified domains) (maybe over-eng)
54 - exceptions (avoid ache for specified domains) (maybe over-eng)
55 - persistant vs. transitory cache
56
57 - cache data store via Berkely db to allow for persistance
58
59 - negative cache TTL derived from SOA
60
61 - positive cache TTL
62
63 - max entries - flush oldest entries when max reached
64
65 - if a TTL for an entry in the cache is within 1 minute of expiring the
66 library should refresh that cache entry after answering the query so
67 that the next request for that entry does not experience latency

project-doc/trustanchor.txt less more
0 The problem of how to fetch the trust anchor for DNSSEC validation can
1 be solved in a number of different ways. RFC 5011 provides a process
2 for updating the trust anchor, however the fundamental problem of how
3 to boot strap a trust anchor is a little more difficult.
4
5 Each of the solutions spans a continuum from easy for the operator but
6 offering weak security to hard for the operator but offering strong
7 security. Some of the options we considered are:
8
9
10 Manual
11 ------
12 If the system operator manually fetches the KSK from a well trusted
13 source and places it on the system he can rest assured that the trust
14 anchor is the most reliable. This is also the most difficult approach
15 and fits least well with our goal of providing an easy to use library
16 for non-DNS experts.
17
18 Manual fetching can be done via a web browser, if the user ensures
19 that he handles the certificate for the ICANN website then it is a
20 respectably secure approach.
21
22
23 Key Fetch Tool in Source
24 ------------------------
25 An application can be provided with the library that the system
26 operator can invoke to bootstrap the key material. This application
27 would include the ICANN website and could perform the key retrieval
28 using a valid certificate. Although the certificate may be included in
29 the source tree, the certificates are typically longer lived than the
30 root KSK.
31
32
33 Key in Source
34 -------------
35 The KSK can be placed in the sources which is probably the easiest for
36 the system operator and is sufficiently secure provided the source
37 deliver process is secure.
38
39 One downside to this approach is that the source package becomes stale
40 following a KSK roll. This can be partially mitigated by providing
41 clear diagnostic messages for the user if they attempt to validate
42 DNSSEC responses with outdated keys.
43
44
45 Automatically Fetch Key Via ICANN Website
46 -----------------------------------------
47 One of the easiest approaches is to embed the URL from which we fetch
48 the KSK into the sources, the library can quietly fetch the KSK if one
49 isn't available on the system. This has some potential security
50 risks.

98 <p class=title2>Paul Hoffman, Editor</p>
99 <p class=title2>Document version: "getdns December 2013"</p>
100
101 <p>This document describes a modern asynchronous DNS API. This new API is intended to be useful to
102 application developers and operating system distributors as a way of making
103 all types of DNS information easily available in many types of programs. The major features
104 of this new API are:</p>
105
106 <ul>
107 <li>Full support for event-driven programming</li>
108 <li>Supports DNSSEC in multiple ways</li>
109 <li>Mirroring of the resolution in <code>getaddrinfo()</code></li>
110 <li>Easily supports all RRtypes, even those yet to be defined</li>
111 </ul>
112
113 <p>There is more background into the design and future goals of this API
114 <a href="#Commentary">later in this document</a>.</p>
115
116 <p>This document was discussed on the <a href="http://www.vpnc.org/mailman/listinfo/getdns-api">
117 getdns-api mailing list</a>; future versions of the API might be discussed there as well.

121
122 <h1>1. The <code>getdns</code> Async Functions</h1>
123
124 <p>The API has four async functions:</p>
125
126 <ul>
127
128 <li><code>getdns_address</code> for doing <code>getaddrinfo()</code>-like address lookups</li>
129
130 <li><code>getdns_hostname</code> for doing <code>getnameinfo()</code>-like name lookups</li>
131
132 <li><code>getdns_service</code> for getting results from SRV lookups</li>
133
134 <li><code>getdns_general</code> for looking up any type of DNS record</li>
135
136 </ul>
137
138 <h2>1.1 <code>getdns_general()</code></h2>
139
140 <div class=forh id="getdnsfuncgeneral">getdns_return_t
141 getdns_general(
142 struct getdns_context *context,
143 const char *name,
144 uint16_t request_type,
145 struct getdns_dict *extensions,
146 void *userarg,
147 getdns_transaction_t *transaction_id,
148 getdns_callback_t callbackfn
149 );
150 </div>
151
152 <p class=define><code><b>context</b></code></p>
153 <p class=descrip>A pointer to the DNS context that is to be used with this call. DNS contexts are
154 described <a href="#Contexts">later in this document</a>. Note that a context <i>must</i> be created
155 before calling the function.</p>
156
157 <p class=define><code><b>*name</b></code></p>
158 <p class=descrip>This is a null-terminted string consisting of either an
159 ASCII-based domain name to be looked up, or a null-terminted text string that is an IPv4 or IPv6 address.
160 The values here follow the rules in section 2.1 of RFC 4343
161 to allow non-ASCII octets and special characters in labels.</p>
162
163 <p class=define><code><b>request_type</b></code></p>
164 <p class=descrip>Specifies the RRtype for the query; the RRtype numbers are listed in the IANA
165 registry. For example, to get the NS records, <code>request_type</code> would be 2. The API also has
166 defined macros for most of the RRtypes by name; the definition names all start with
167 "<code>GETDNS_RRTYPE_</code>". For example, to get the NS records, you can also set the
168 <code>request_type</code> to <code>GETDNS_RRTYPE_NS</code>.
169 (The full list of request types is always
170 <a href="http://www.iana.org/assignments/dns-parameters/dns-parameters.xml">here</a>.)</p>
171
172 <p class=define><code><b>*extensions</b></code></p>
173 <p class=descrip>Specifies the extensions for this request; the value may be NULL if there are no
174 extensions. See <a href="#Extensions">the section below</a> for information on how to specify
175 the extensions used for a request.</p>
176
177 <p class=define><code><b>*userarg</b></code></p>
178 <p class=descrip>A void* that is passed to the function, which the funciton
179 returns to the callback function untouched. <code>userarg</code> can be used by the callback
180 function for any user-specific data needed. This can be NULL.</p>
181
182 <p class=define><code><b>*transaction_id</b></code></p>
183 <p class=descrip>A pointer to a value that is filled in by the
184 function to identify the callback being made.
185 This pointer can be NULL, in which case it is ignored and no value is assigned.
186 The <code>getdns_cancel_callback()</code> function uses the
187 <code>transaction_id</code> to determine which callback is to be cancelled.
188 If the function fails,
189 <code>transaction_id</code> is set to 0.</p>
190
191 <p class=define><code><b>*callbackfn</b></code></p>
192 <p class=descrip>A pointer to a callback function that is defined by the application.
193 Typically, the callback function will do all the processing on the results from
194 the API. The parameters of the callback are defined below. This really needs
195 to be a pointer to a function (and not something like NULL); otherwise, the
196 results are unpredictable.</p>
197
198 <p>The async <code>getdns</code> functions return <code>GETDNS_RETURN_GOOD</code> if the call was properly formatted.
199 It returns <code>GETDNS_RETURN_BAD_DOMAIN_NAME</code> if the API determines that the name passed to
200 the function was bad, <code>GETDNS_RETURN_BAD_CONTEXT</code> if the context pointer is bad,
201 <code>GETDNS_RETURN_NO_SUCH_EXTENSION</code> if one or more extensions do not exist, or
202 <code>GETDNS_RETURN_EXTENSION_MISFORMAT</code> if the contents of one or more of the
203 extensions is incorrect. All of the return values are given <a
204 href="#ReturnCodes">later in this document</a>.</p>
205
206 <h2>1.2 <code>getdns_address()</code></h2>
207
208 <div class=forh id="getdnsfuncaddress">getdns_return_t
209 getdns_address(
210 struct getdns_context *context,
211 const char *name,
212 struct getdns_dict *extensions,
213 void *userarg,
214 getdns_transaction_t *transaction_id,
215 getdns_callback_t callbackfn
216 );
217 </div>
218
219 <p>There are three critical differences between <code>getdns_address()</code> and
220 <code>getdns_general()</code> beyond the missing <code>request_type</code> argument:</p>
221
222 <ul>
223
224 <li>In <code>getdns_address()</code>, the <code>name</code> argument can only take a host name.</li>
225
226 <li>You do not need to include a <code>return_both_v4_and_v6</code> extension with the call in
227 <code>getdns_address()</code>: it will always return both IPv4 and IPv6 addresses.</li>
228
229 <li><code>getdns_address()</code> always uses all of namespaces from the context (to better emulate
230 <code>getaddrinfo()</code>), while <code>getdns_general()</code> only uses the DNS namespace.</li>
231
232 </ul>
233
234 <h2>1.3 <code>getdns_hostname()</code></h2>
235
236 <div class=forh id="getdnsfunchostname">getdns_return_t
237 getdns_hostname(
238 struct getdns_context *context,
239 struct getdns_dict *address,
240 struct getdns_dict *extensions,
241 void *userarg,
242 getdns_transaction_t *transaction_id,
243 getdns_callback_t callbackfn
244 );
245 </div>
246
247 <p>The address is given as a <code>getdns_dict</code> data structure (defined below). The list must
248 have two names: <code>address_type</code> (whose value is a bindata; it is currently either "IPv4"
249 or "IPv6" (which are case-sensitive)) and <code>address_data</code> (whose value is a bindata).</p>
250
251 <h2>1.4 <code>getdns_service()</code></h2>
252
253 <div class=forh id="getdnsfuncservice">getdns_return_t
254 getdns_service(
255 struct getdns_context *context,
256 const char *name,
257 struct getdns_dict *extensions,
258 void *userarg,
259 getdns_transaction_t *transaction_id,
260 getdns_callback_t callbackfn
261 );
262 </div>
263
264 <p><code>name</code> must be a domain name for an SRV lookup; the call returns the
265 relevant SRV information for the name.</p>
266
267 <h2>1.5 Callback Functions for <code>getdns</code></h2>
268
269 <p>A call to the async <code>getdns</code> functions typically returns before any network or file I/O occurs. After
270 the API marshalls all the needed information, it calls the callback function that was passed by the
271 application. The callback function might be called at any time, even before the calling function
272 has returned. The API guarantees that the callback will be called exactly once unless the calling function
273 returned an error, in which case the callback function is never called.<p>
274
275 <p>The <code>getdns</code> calling function calls the callback with the parameters defined
276 as follows:</p>
277 <div class=forh id="getdns_callback_t">
278 typedef void (*getdns_callback_t)(
279 struct getdns_context *context,
280 uint16_t callback_type,
281 struct getdns_dict *response,
282 void *userarg,
283 getdns_transaction_t transaction_id);
284 </div>
285
286 <p class=define><code><b>context</b></code></p>
287 <p class=descrip>The DNS context that was used in the calling function. See <a
288 href="#ContextInitial">below</a> for a description of the basic use of contexts, and <a
289 href="#Contexts">later</a> for more advanced use.</p>
290
291 <p class=define><code><b>callback_type</b></code></p>
292 <p class=descrip>Supplies the reason for the callback. See below for the codes and reasons.</p>
293
294 <p class=define><code><b>*response</b></code></p>
295 <p class=descrip>A response object with the response data. This is described below. The response
296 object is part of the API's memory space, and will be freed by the API with the callback returns.</p>
297
298 <p class=define><code><b>*userarg</b></code></p>
299 <p class=descrip>Identical to the <code>*userarg</code> passed to the calling function.</p>
300
301 <p class=define><code><b>transaction_id</b></code></p>
302 <p class=descrip>The transaction identifier that was assigned by the calling function.</p>
303
304 <p>The following are the values for callback_type.</p>
305
306 <p class=define>GETDNS_CALLBACK_COMPLETE</p>
307 <p class=descrip>The response has the requested data in it</p>
308 <p class=define>GETDNS_CALLBACK_CANCEL</p>
309 <p class=descrip>The calling program cancelled the callback; response is NULL</p>
310 <p class=define>GETDNS_CALLBACK_TIMEOUT</p>
311 <p class=descrip>The requested action timed out; response is NULL</p>
312 <p class=define>GETDNS_CALLBACK_ERROR</p>
313 <p class=descrip>The requested action had an error; response is NULL</p>
314
315
316 <h2>1.6 <a id="ContextInitial">Setting Up The DNS Context</a></h2>
317
318 <p>Calls to <code>getdns</code> functions require a DNS context, which is a group of API settings
319 that affect how DNS calls are made. For most applications, a default context is sufficient.</p>
320
321 <p>To create a new DNS context, use the function:</p>
322
323 <div class=forh>getdns_return_t
324 getdns_context_create(
325 struct getdns_context **context,
326 int set_from_os
327 );
328 </div>
329
330 <p class=cont>The call to <code>getdns_context_create</code> immediately returns a context that can
331 be used with other API calls; that context contains the API's default values. Most applications will
332 want <code>set_from_os</code> set to <code>1</code>.</p>
333
334 <div class=forh>getdns_return_t
335 getdns_context_create_with_memory_functions(
336 struct getdns_context **context,
337 int set_from_os,
338 void *(*malloc)(size_t),
339 void *(*realloc)(void *, size_t),
340 void (*free)(void *)
341 );
342 getdns_return_t
343 getdns_context_create_with_extended_memory_functions(
344 struct getdns_context **context,
345 int set_from_os,
346 void *userarg,
347 void *(*malloc)(void *userarg, size_t),
348 void *(*realloc)(void *userarg, void *, size_t),
349 void (*free)(void *userarg, void *)
350 );
351 </div>
352
353 <p>To clean up the context, including cleaning up all outstanding transactions that were called
354 using this context, use the function:</p>
355
356 <div class=forh>void
357 getdns_context_destroy(
358 struct getdns_context *context
359 );
360 </div>
361
362 <p class=cont>When <code>getdns_context_destroy()</code> returns, the
363 application knows that all outstanding transactions associated with this
364 context will have been called; callbacks that had not been called before
365 <code>getdns_context_destroy()</code> was called will be called with a callback_type of
366 <code>GETDNS_CALLBACK_CANCEL</code>. <code>getdns_context_destroy()</code> returns after
367 all of the needed cleanup is done and callbacks are made.</p>
368
369 <h2>1.7 Canceling a Callback</h2>
370
371 <p>To cancel an outstanding callback, use the following function.</p>
372
373 <div class=forh>getdns_return_t
374 getdns_cancel_callback(
375 struct getdns_context *context,
376 getdns_transaction_t transaction_id
377 );
378 </div>
379
380 <p class=cont>This causes the API to call the callback with a <code>callback_type</code> of
381 <code>GETDNS_CALLBACK_CANCEL</code> if the callback for this <code>transaction_id</code> has not
382 already been called. This will cancel the callback regardless of what the original call was
383 doing (such as in the middle of a DNS request, while DNSSEC validation is happening, and so on).
384 The callback code for cancellation should clean up any memory related to the
385 identified call, such as to deallocate the memory for the userarg.
386 <code>getdns_cancel_callback()</code> may return immediately, even before the callback finishes its
387 work and returns. Calling <code>getdns_cancel_callback()</code> with a <code>transaction_id</code>
388 of a callback that has already been called or an unknown <code>transaction_id</code> returns
389 <code>GETDNS_RETURN_UNKNOWN_TRANSACTION</code>; otherwise, <code>getdns_cancel_callback()</code>
390 returns <code>GETDNS_RETURN_GOOD</code>.</p>
391
392 <h2>1.8 Event-driven Programs</h2>
393
394 <p>Event-driven programs (sometimes called "async programs") require an event
395 base and event loop (among other things). Different event libraries have
396 different structures or the event base. Because of this, there is no standard
397 method to set the event base in the DNS API: those are all added as
398 extensions. The API is distributed as a core package and one or more sets of
399 extensions to align with event libraries. It is mandatory to use one of the extension
400 functions to set the event base in the DNS context; this is required before
401 calling any event-driven calls like the <code>getdns</code> functions.</p>
402
403 <p>Each implementation of the DNS API will specify an extension function that
404 tells the DNS context which event base is being used. For example, one
405 implementation of this API that uses the libevent event library might name
406 this function "<code>getdns_extension_set_libevent_base()</code>" while
407 another might name it
408 "<code>getdns_extension_set_eventbase_for_libevent()</code>"; the two
409 extension functions could have very different calling patterns and return
410 values. Thus, the application developer <i>must</i> read the API documentation
411 (not just this design document) in order to determine what extension function
412 to use to tell the API the event base to use.</p>
413
414 <p>The structure of a typical event-driven application might look like the following pseudocode.
415 The code in italics is specific to the event mechanism.</p>
416
417 <pre>
418 Includes for one or more regular C libraries
419 <i>An include for the getdns library specific to the event library you use</i>
420 Definition of your callback function
421 Get the DNS data from the allocated pointer
422 Process that data
423 Check for errors
424 Definition of main()
425 Create context
426 <i>Set up your event base</i>
427 <i>Point the context to your event base</i>
428 Set up the getdns call arguments
429 Make the getdns call
430 Check if the getdns return is good
431 Destroy the context
432 Exit
433 </pre>
434
435 <p>The API does not have direct support for a polling interface. Instead, the callback interface is
436 specifically designed to allow an application that wants to process results in polling instead of in
437 callbacks to be able to create its own polling interface fairly trivially. Such a program would
438 create a data structure for the calls, including their <code>transaction_id</code> and
439 <code>userarg</code>. The <code>userarg</code> could be the polling data structure or have a pointer to it.
440 The application would have just
441 one callback function for all requests, and that function would copy the <code>response</code> into
442 application memory, update the data structure based on the <code>transaction_id</code> index,
443 and return from the callback. The polling code could then check the data structure for any updates
444 at its leisure.</p>
445
446 <h2>1.9 Calling the API Synchronously (Without Events)</h2>
447
448 <p>Thare are functions parallel to the four <code>getdns</code> async functions,
449 except that there is no callback. That is, when an application calls one of these
450 synchronous functions, the
451 API gathers all the required information and then returns the result. The value returned is exactly the
452 same as the response returned in the callback if you had used the async version of the function.</p>
453
454 <div class=forh>getdns_return_t
455 getdns_general_sync(
456 struct getdns_context *context,
457 const char *name,
458 uint16_t request_type,
459 struct getdns_dict *extensions,
460 struct getdns_dict **response
461 );
462 </div>
463
464 <div class=forh>getdns_return_t
465 getdns_address_sync(
466 struct getdns_context *context,
467 const char *name,
468 struct getdns_dict *extensions,
469 struct getdns_dict **response
470 );
471 </div>
472
473 <div class=forh>getdns_return_t
474 getdns_hostname_sync(
475 struct getdns_context *context,
476 struct getdns_dict *address,
477 struct getdns_dict *extensions,
478 struct getdns_dict **response
479 );
480 </div>
481
482 <div class=forh>getdns_return_t
483 getdns_service_sync(
484 struct getdns_context *context,
485 const char *name,
486 struct getdns_dict *extensions,
487 struct getdns_dict **response
488 );
489 </div>
490
491 <p>When you are done with the data in the response, use the following function so that the API can
492 free the memory from its internal pool.</p>
493
494 <pre>void
495 getdns_dict_destroy(
496 struct getdns_dict *response
497 );
498 </pre>
499
500 <h1>2. Data structures in the API</h1>
501
502 <p>The API returns data structures. The data structure is not a representational language like JSON:
503 it is really just a data structure. Data structures can have four types of members:</p>
504
505 <ul>
506
507 <li><span class=default>list</span> is an ordered list, like JSON and Python lists.
508 The members of the list can be any of the four data types.</li>
509
510 <li><span class=default>dict</span> is a name-value pair, like a JSON object or Python dict. The
511 name is a string literal, and the value can be any of the four data types. The order of the
512 name-value pairs in a dict is not important.</li>
513
514 <li><span class=default>int</span> is an integer compatible with uint32_t.</li>
515
516 <li><span class=default>bindata</span> is a struct to hold binary data. It is defined as
517 <code>{ size_t size; uint8_t *binary_stuff; }</code>.</li>
518
519 </ul>
520
521 <p>The API comes with helper functions to get data from the list and dict data types:</p>
522
523 <div class=forh id="datagetters">
524 /* Lists: get the length, get the data_type of the value at a given
525 position, and get the data at a given position */
526 getdns_return_t getdns_list_get_length(struct getdns_list *this_list, size_t *answer);
527 getdns_return_t getdns_list_get_data_type(struct getdns_list *this_list, size_t index, getdns_data_type *answer);
528 getdns_return_t getdns_list_get_dict(struct getdns_list *this_list, size_t index, struct getdns_dict **answer);
529 getdns_return_t getdns_list_get_list(struct getdns_list *this_list, size_t index, struct getdns_list **answer);
530 getdns_return_t getdns_list_get_bindata(struct getdns_list *this_list, size_t index, struct getdns_bindata **answer);
531 getdns_return_t getdns_list_get_int(struct getdns_list *this_list, size_t index, uint32_t *answer);
532
533 /* Dicts: get the list of names, get the data_type of the
534 value at a given name, and get the data at a given name */
535 getdns_return_t getdns_dict_get_names(struct getdns_dict *this_dict, struct getdns_list **answer);
536 getdns_return_t getdns_dict_get_data_type(struct getdns_dict *this_dict, char *name, getdns_data_type *answer);
537 getdns_return_t getdns_dict_get_dict(struct getdns_dict *this_dict, char *name, struct getdns_dict **answer);
538 getdns_return_t getdns_dict_get_list(struct getdns_dict *this_dict, char *name, struct getdns_list **answer);
539 getdns_return_t getdns_dict_get_bindata(struct getdns_dict *this_dict, char *name, struct getdns_bindata **answer);
540 getdns_return_t getdns_dict_get_int(struct getdns_dict *this_dict, char *name, uint32_t *answer);
541 </div>
542
543 <p>All of these helper getter functions return <code>GETDNS_RETURN_GOOD</code> if the call is successful.
544 The list functions will return <code>GETDNS_RETURN_NO_SUCH_LIST_ITEM</code> if the index argument is
545 out of range; the dict functions will return <code>GETDNS_RETURN_NO_SUCH_DICT_NAME</code> if the name
546 argument doesn't exist in the dict. The functions also return <code>GETDNS_RETURN_WRONG_TYPE_REQUESTED</code>
547 if the requested data type doesn't match the contents of the indexed argument or name.</p>
548
549 <p>This document uses graphical representations of data structures. It is important to note that
550 this is only a graphical representation; the brackets, commas, quotation marks, comments, and so on
551 are not part of the data. Also, this document uses macro names instead of some of the int
552 arguments; of course, the data structures have the actual int in them.</p>
553
554 <h2>2.1 Creating Data Structures</h2>
555
556 <p>Some of the features of the API require that you create your own data structures to be used in
557 arguments passed to the API. For example, if you want to use any extensions for the calling functions,
558 you need to create a dict. The requisite functions are:</p>
559
560 <div class=forh id="datasetters">
561 /* Lists: create, destroy, and set the data at a given position */
562 struct getdns_list * getdns_list_create();
563 struct getdns_list * getdns_list_create_with_context(
564 struct getdns_context *context
565 );

607 <p>Lists are extended with the <code>getdns_list_set_</code> calls with the <code>index</code> set to the
608 size of the list (such as 0 for an empty list). Dicts are extended with the <code>getdns_dict_set_</code> calls
609 with the <code>name</code> set to a name that does not yet exist. Name-value pairs are removed with
610 <code>getdns_dict_remove_name()</code>.</p>
611
612 <p>These helper setter functions return <code>GETDNS_RETURN_GOOD</code> if the call is successful.
613 The functions return <code>GETDNS_RETURN_WRONG_TYPE_REQUESTED</code> if the requested data type
614 doesn't match the contents of the indexed argument or name. The list functions will return
615 <code>GETDNS_RETURN_NO_SUCH_LIST_ITEM</code> if the index argument is higher than the length of the
616 list. <code>getdns_dict_remove_name()</code> will return
617 <code>GETDNS_RETURN_NO_SUCH_DICT_NAME</code> if the name argument doesn't exist in the dict. </p>
618
619 <h1>3. <a id="Extensions">Extensions</a></h1>
620
621 <p>Extensions are dict data structures. The names in the dict are the names of the extensions.
622 The definition of each extension describes the value associated with the name. For most extensions,
623 it is an on-off boolean, and the value is <code>GETDNS_EXTENSION_TRUE</code>. (There is
624 not currently a good reason to specify an extension name and give it a value of <code>GETDNS_EXTENSION_FALSE</code>,
625 but that is allowed by the API.)</p>
626
627 <p>For example, to create a dict for extensions and specify the extension to only return
628 results that have been validated with DNSSEC, you might use:</p>
629
630 <pre>
631 /* . . . */
632 struct getdns_dict * this_extensions = getdns_dict_create();
633 this_ret = getdns_dict_set_int(this_extensions, "dnssec_return_only_secure", GETDNS_EXTENSION_TRUE);
634 /* . . . Do some processing with the extensions and results . . . */
635 /* Remember to clean up memory*/
636 getdns_dict_destroy(this_extensions);
637 </pre>
638
639 <p>The extensions described in this section are are:
640
641 <ul>
642
643 <li><code>dnssec_return_status</code></li>
644
645 <li><code>dnssec_return_only_secure</code></li>
646
647 <li><code>dnssec_return_supporting_responses</code></li>
648
649 <li><code>return_both_v4_and_v6</code></li>
650
651 <li><code>add_opt_parameters</code></li>
652
653 <li><code>add_warning_for_bad_dns</code></li>
654
655 <li><code>specify_class</code></li>
656
657 <li><code>return_api_information</code></li>
658
659 <li><code>return_call_debugging</code></li>
660
661 </ul>
662
663 <h2>3.1 Extensions for DNSSEC</h2>
664
665 <p>If an application wants the API to do DNSSEC validation for a request, it must set one or more
666 DNSSEC-related extensions. Note that the default is for none of these extensions to be set and
667 the API will not perform DNSSEC, and thus will return results sooner.</p>
668
669 <p>To return the DNSSEC status for each DNS record in the <code>replies_tree</code> list, use the
670 <code>dnssec_return_status</code> extension. The extension's value (an int) is set to
671 <code>GETDNS_EXTENSION_TRUE</code> to cause the returned status to have the name
672 <code>dnssec_status</code> (an int) added to the other names in the record's dict ("header",
673 "question", and so on). The values for that name are <code>GETDNS_DNSSEC_SECURE</code>,
674 <code>GETDNS_DNSSEC_BOGUS</code>, <code>GETDNS_DNSSEC_INDETERMINATE</code>, and
675 <code>GETDNS_DNSSEC_INSECURE</code>. Thus, a reply might look like:</p>
676
677 <pre>
678 { # This is the first reply
679 "dnssec_status": GETDNS_DNSSEC_INDETERMINATE,
680 "header": { "id": 23456, "qr": 1, "opcode": 0, ... },
681 . . .
682 </pre>
683
684 <p>If instead of returning the status, you want to only see secure results, use the
685 <code>dnssec_return_only_secure</code> extension. The extension's value (an int) is set to
686 <code>GETDNS_EXTENSION_TRUE</code> to cause only records that the API can validate as secure with
687 DNSSEC to be returned in the <code>replies_tree</code> and <code>replies_full</code> lists. No
688 additional names are added to the dict of the record; the change is that some records might not
689 appear in the results. When this context option is set, if the API receives DNS replies but none
690 are determined to be secure, the error code at the top level of the response object is
691 <code>GETDNS_RESPSTATUS_NO_SECURE_ANSWERS</code>.</p>
692
693 <p>Applications that want to do their own validation will want to have the DNSSEC-related records
694 for a particular response. Use the <code>dnssec_return_supporting_responses</code> extension. The
695 extension's value (an int) is set to <code>GETDNS_EXTENSION_TRUE</code> to cause a set
696 of additional DNSSEC-related records needed for validation to be returned in the response object.
697 This set comes as <code>additional_dnssec</code> (a list) at the top level of the response object.
698 This list includes any trust anchors needed for the validation. Thus, a reply might look like:</p>
699
700 <pre>
701 { # This is the response object
702 "additional_dnssec": [ &lt;bindata of the first DNSSEC record&gt;, &lt;bindata of the second DNSSEC record&gt; ... ],
703 "replies_tree":
704 [
705 . . .
706 </pre>
707
708 <p>If a request is using a context in which stub resolution is set, and that request also has
709 any of the <code>dnssec_return_status</code>, <code>dnssec_return_only_secure</code>, or
710 <code>dnssec_return_supporting_responses</code> extensions specified, the API will not perform
711 the request and will instead return an error of <code>GETDNS_RETURN_DNSSEC_WITH_STUB_DISALLOWED</code>.</p>
712
713 <h2>3.2 Returning Both IPv4 and IPv6 Responses</h2>
714
715 <p>Many applications want to get both IPv4 and IPv6 addresses in a single call so that the results
716 can be processed together. The <code>getdns_address</code> and <code>getdns_address_sync</code>
717 functions are able to do this automatically. If you are using the <code>getdns_general</code> or
718 <code>getdns_general_sync</code> function, you can enable this with the
719 <code>return_both_v4_and_v6</code> extension. The extension's value (an int) is set to
720 <code>GETDNS_EXTENSION_TRUE</code> to cause the results to be the lookup of either A or AAAA records
721 to include any A and AAAA records for the queried name (otherwise, the extension does nothing).
722 These results are expected to be used with Happy Eyeballs systems that will find the best socket for
723 an application.</p>
724
725 <h2>3.3 Setting Up OPT Resource Records</h2>
726
727 <p>For lookups that need an OPT resource record in the Additional Data section, use the
728 <code>add_opt_parameters</code> extension. The extension's value (a dict) contains the
729 parameters; these are described in more detail in RFC 2671. They are:</p>
730
731 <ul>
732
733 <li><code>maximum_udp_payload_size</code> (an int), a value between 512 and 65535; if not specified,
734 this defaults to those from the DNS context</li>
735
736 <li><code>extended_rcode</code> (an int), a value between 0 and 255; if not specified,
737 this defaults to those from the DNS context</li>
738
739 <li><code>version</code> (an int), a value between 0 and 255; if not specified, this
740 defaults to 0</li>
741
742 <li><code>do_bit</code> (an int), a value between 0 and 1; if not specified, this defaults
743 to those from the DNS context</li>
744
745 <li><code>options</code> (a list) contains dicts for each option to be specified.
746 Each list time contains two names: <code>option_code</code> (an int) and <code>option_data</code>
747 (a bindata). The API marshalls the entire set of options into a properly-formatted RDATA
748 for the resource record.</li>
749
750 </ul>
751
752 <p>It is very important to note that the OPT resource record specified in the
753 <code>add_opt_parameters</code> extension might not be the same the one that the API sends in the
754 query. For example, if the application also includes any of the DNSSEC extensions, the API will make
755 sure that the OPT resource record sets the resource record appropriately, making the needed changes
756 to the settings from the <code>add_opt_parameters</code> extension.</p>
757
758 <p>The use of this extension can conflict with the values in the DNS context. For example,
759 the default for an OS might be a maximum payload size of 65535, but the extension might specify
760 1550. In such a case, the API will honor the values stated in the extension, but will honor the
761 values from the DNS context if values are not given in the extension.</p>
762
763 <h2>3.4 Getting Warnings for Responses that Violate the DNS Standard</h2>
764
765 <p>To receive a warning if a particular response violates some parts of the DNS standard, use
766 the <code>add_warning_for_bad_dns</code> extension. The extension's value (an int) is set to
767 <code>GETDNS_EXTENSION_TRUE</code> to cause each reply in the <code>replies_tree</code>
768 to contain an additional name, <code>bad_dns</code> (a list). The list is zero or more
769 ints that indicate types of bad DNS found in that reply. The list of values is:
770
771 <p class=define>GETDNS_BAD_DNS_CNAME_IN_TARGET</p>
772 <p class=descrip>A DNS query type that does not allow a target to be a CNAME pointed to a CNAME</p>
773 <p class=define>GETDNS_BAD_DNS_ALL_NUMERIC_LABEL</p>
774 <p class=descrip>One or more labels in a returned domain name is all-numeric; this is not legal for a hostname</p>
775 <p class=define>GETDNS_BAD_DNS_CNAME_RETURNED_FOR_OTHER_TYPE</p>
776 <p class=descrip>A DNS query for a type other than CNAME returned a CNAME response</p>
777
778
779 <h2>3.5 Using Other Class Types</h2>
780
781 <p>The vast majority of DNS requests are made with the Internet (IN) class. To make a request in a
782 different DNS class, use, the <code>specify_class</code> extension. The extension's value (an int)
783 contains the class number. Few applications will ever use this extension.</p>
784
785 <h2>3.6 Extensions Relating to the API</h2>
786
787 <p>An application might want to see information about the API itself. Use the
788 <code>return_api_information</code> extension. An application that wants to get this information
789 before a "real" query is issued can add this extension to a PTR query for 127.0.0.1.
790 The extension's value (an int) is set to
791 <code>GETDNS_EXTENSION_TRUE</code> to add the following to the top level of the response object:</p>
792
793 <ul>
794
795 <li><code>version_string</code> (a bindata) represents the version string for this version of the DNS
796 API.</li>
797
798 <li><code>implementation_string</code> (a bindata) is a string set by the API implementer. It might
799 be human-readable, and it might have information in it useful to an application developer (but it doesn't
800 have to).</li>
801
802 <li><code>resolver_type</code> (an int) is the type of resolver that the API is acting as in this context:
803 <code>GETDNS_CONTEXT_RECURSING</code> or <code>GETDNS_CONTEXT_STUB</code> (it will be
804 a recursing resolver unless the application changed this in a context.</li>
805
806 <li><code>all_context</code> (a dict) with names for all the types of context. This can be used with
807 getdns_pretty_print_dict() for debugging.</li>
808
809 </ul>
810
811 <p>An application might want to see debugging information for queries such as the length of time it
812 takes for each query to return to the API. Use the <code>return_call_debugging</code> extension. The
813 extension's value (an int) is set to <code>GETDNS_EXTENSION_TRUE</code> to add the name
814 <code>call_debugging</code> (a list) to the top level of the response object. Each member of the
815 list is a dict that represents one call made for the call to the API. Each member has the following
816 names:</p>
817
818 <ul>
819 <li><code>query_name</code> (a bindata) is the name that was sent</li>
820 <li><code>query_type</code> (an int) is the type that was queried for</li>
821 <li><code>query_to</code> (a bindata) is the address to which the query was sent</li>
822 <li><code>start_time</code> (a bindata) is the time the query started in milliseconds since the epoch,
823 represented as a uint64_t</li>
824 <li><code>end_time</code> (a bindata) is the time the query was received in milliseconds since the epoch,
825 represented as a uint64_t</li>
826 <li><code>entire_reply</code> (a bindata) is the entire response received</li>
827 <li><code>dnssec_result</code> (an int) is the DNSSEC status, or <code>GETDNS_DNSSEC_NOT_PERFORMED</code>
828 if DNSSEC validation was not performed</li>
829 </ul>
830
831 <h1>4. Response Data from Queries</h1>
832
833 <p>The callback function contains a pointer to a response object.
834 A response object is always a dict. The response
835 object always contains at least three names: <code>replies_full</code> (a list) and
836 <code>replies_tree</code> (a list), and <code>status</code> (an int).
837 <code>replies_full</code> is a list of DNS replies (each is bindata) as they appear on the wire.
838 <code>replies_tree</code> is a list of DNS replies (each is a dict) with the various part of the
839 reply parsed out. <code>status</code> is a status code for the query.</p>
840
841 <p>Because the API might be extended in the future, a response object might also contain names other
842 than <code>replies_full</code>, <code>replies_tree</code>, and <code>status</code>. Similarly, any
843 of the dicts described here might be extended in later versions of the API. Thus, an application
844 using the API must not assume that it knows all possible names in a dict.</p>
845
846 <p>The following lists the status codes for response objects. Note that, if the status is that there
847 are no responses for the query, the lists in <code>replies_full</code> and <code>replies_tree</code>
848 will have zero length.</p>
849
850 <p class=define>GETDNS_RESPSTATUS_GOOD</p>
851 <p class=descrip>At least one response was returned</p>
852 <p class=define>GETDNS_RESPSTATUS_NO_NAME</p>
853 <p class=descrip>Queries for the name yielded all negative responses</p>
854 <p class=define>GETDNS_RESPSTATUS_ALL_TIMEOUT</p>
855 <p class=descrip>All queries for the name timed out</p>
856 <p class=define>GETDNS_RESPSTATUS_NO_SECURE_ANSWERS</p>
857 <p class=descrip>The context setting for getting only secure responses was specified, and at least one DNS response was received, but no DNS response was determined to be secure through DNSSEC.</p>
858
859
860 <p>The top level of <code>replies_tree</code> can optionally have the following names: <code>canonical_name</code> (a
861 bindata), <code>intermediate_aliases</code> (a list), <code>answer_ipv4_address</code> (a bindata),
862 <code>answer_ipv6_address</code> (a bindata), and <code>answer_type</code> (an int).</p>
863
864 <ul>
865
866 <li>The value of <code>canonical_name</code> is the name that the API used for its lookup. It is in
867 FQDN presentation format.</li>
868
869 <li>The values in the <code>intermediate_aliases</code> list are domain names from any CNAME or
870 unsynthesized DNAME found when resolving the original query. The list might have zero entries
871 if there were no CNAMEs in the path. These may be useful, for example, for name comparisons
872 when following the rules in RFC 6125.</li>
873
874 <li>The value of <code>answer_ipv4_address</code> and <code>answer_ipv6_address</code> are
875 the addresses of the server from which the answer was received.</li>
876
877 <li>The value of <code>answer_type</code> is the type of name service that generated the response.
878 The values are:</li>
879
880 </ul>
881
882 <p class=define>GETDNS_NAMETYPE_DNS</p>
883 <p class=descrip>Normal DNS (RFC 1035)</p>
884 <p class=define>GETDNS_NAMETYPE_WINS</p>
885 <p class=descrip>The WINS name service (some reference needed)</p>
886
887
888 <p>If the call was <code>getdns_address</code> or <code>getdns_address_sync</code>, the top level
889 of <code>replies_tree</code> has an additional name, <code>just_address_answers</code> (a list).
890 The value of <code>just_address_answers</code> is a list that contains all of the A and AAAA
891 records from the answer sections of any of the replies, in the order they appear in the replies.
892 Each item in the list is a dict with at least two names: <code>address_type</code> (whose value is
893 a bindata; it is currently either "IPv4" or "IPv6") and <code>address_data</code> (whose value is a bindata).
894 Note that the <code>dnssec_return_only_secure</code> extension affects
895 what will appear in the <code>just_address_answers</code> list. Also note if later versions of the
896 DNS return other address types, those types will appear in this list as well.</p>
897
898 <p>The API can make service discovery through SRV records easier. If
899 the call was <code>getdns_service</code> or <code>getdns_service_sync</code>,
900 the top level of <code>replies_tree</code> has an additional name,
901 <code>srv_addresses</code> (a list).
902 The list is ordered by priority and weight based on the weighting
903 algorithm in RFC 2782, lowest priority value first. Each element
904 of the list is dict has at least two names: <code>port</code> and <code>domain_name</code>. If the
905 API was able to determine the address of the target domain name (such as from its cache or from the
906 Additional section of responses), the dict for an element will also contain
907 <code>address_type</code> (whose value is a bindata; it is currently either "IPv4" or "IPv6") and
908 <code>address_data</code> (whose value is a bindata). Note that the
909 <code>dnssec_return_only_secure</code> extension affects what will appear in the
910 <code>srv_addresses</code> list.</p>
911
912 <h2>4.1 Structure of DNS <code>replies_tree</code></h2>
913
914 <p>The names in each entry in the the <code>replies_tree</code> list for DNS responses include
915 <code>header</code> (a dict), <code>question</code> (a dict), <code>answer</code> (a list),
916 <code>authority</code> (a list), and <code>additional</code> (a list), corresponding to the sections
917 in the DNS message format. The answer, authority, and additional lists each contain zero or more
918 dicts, with each dict in each list representing a resource record.</p>
919
920 <p>The names in the <code>header</code> dict are all the fields from Section 4.1.1. of RFC 1035.
921 They are: <code>id</code>, <code>qr</code>, <code>opcode</code>, <code>aa</code>, <code>tc</code>,
922 <code>rd</code>, <code>ra</code>, <code>z</code>, <code>rcode</code>, <code>qdcount</code>,
923 <code>ancount</code>, <code>nscount</code>, and <code>arcount</code>. All are ints.</p>
924
925 <p>The names in the <code>question</code> dict are the three fields from Section 4.1.2. of RFC 1035:
926 <code>qname</code> (a bindata), <code>qtype</code> (an int), and <code>qclass</code> (an int).</p>
927
928 <p>Resource records are a bit different than headers and question sections in that the RDATA portion
929 often has its own structure. The other names in the resource record dicts are <code>name</code> (a
930 bindata), <code>type</code> (an int), <code>class</code> (an int), <code>ttl</code> (an int) and
931 <code>rdata</code> (a dict); there is no name equivalent to the RDLENGTH field.</p>
932
933 <p>The <code>rdata</code> dict has different names for each response type. There is a <a
934 href="#TypeList">complete list of the types defined</a> in the API. For names that end in
935 "-obsolete" or "-unknown", the bindata is the entire RDATA field. For example, the
936 <code>rdata</code> for an A record has a name <code>ipv4_address</code> (a bindata); the
937 <code>rdata</code> for an SRV record has the names <code>priority</code> (an int),
938 <code>weight</code> (an int), <code>port</code> (an int), and <code>target</code> (a bindata).</p>
939
940 <p>Each <code>rdata</code> dict also has a <code>rdata_raw</code> field (a bindata). This is useful
941 for types not defined in this version of the API. It also might be of value if a later version of
942 the API allows for additional parsers. Thus, doing a query for types not known by the API still will
943 return a result: an <code>rdata</code> with just a <code>rdata_raw</code>.</p>
944
945 <p>It is expected that later extensions to the API will give some DNS types different names. It is
946 also possible that later extensions will change the names for some of the DNS types listed above.</p>
947
948 <p>For example, a response to a <code>getdns_address()</code> call for www.example.com would
949 look something like this:</p>
950
951 <pre>
952 { # This is the response object
953 "replies_full": [ &lt;bindata of the first response&gt;, &lt;bindata of the second response&gt; ],
954 "just_address_answers": [ &lt;bindata of 0x0a0b0c01&gt;, &lt;bindata of 0x33445566334455663344556633445566&gt; ],
955 "canonical_name": &lt;bindata of "www.example.com"&gt;,
956 "answer_type": GETDNS_NAMETYPE_DNS,
957 "intermediate_aliases": [],
958 "replies_tree":

1019 <p>In DNS responses, domain names are treated special. RFC 1035 describes a form of name compression
1020 that requires that the entire record be available for analysis. The API deals with this by
1021 converting compressed names into full names when returning names in the <code>replies_tree</code>.
1022 This conversion happens for <code>qname</code> in <code>question</code>; <code>name</code> in the
1023 <code>answer</code>, <code>authority</code>, and <code>additional</code>; and in domain names in the
1024 data in names under <code>rdata</code> where the response type is AFSDB, CNAME, MX, NS, PTR, RP, RT, and SOA.</p>
1025
1026 <h2>4.2 Converting Domain Names</h2>
1027
1028 <p>Names in DNS fields are stored in a fashion very different from the normal presentation format
1029 normally used in applications. The DNS format is described in the first paragraph in Section 3.1 of
1030 RFC 1035; the presentation format here is a null-terminated string with interior dots. These helper
1031 functions only work with names in the DNS format that are not compressed. They are useful for
1032 converting domain names in the <code>replies_tree</code> to and from the FQDN presentation
1033 format.</p>
1034
1035 <p><code>getdns_convert_dns_name_to_fqdn()</code> converts a domain name in DNS format to the
1036 presentation format. For example, the hex sequence <code>03 77 77 77 07 65 78 61 6d 70 6c 65 03 63
1037 6f 6d 00</code> would be converted to "www.example.com".
1038 <code>getdns_convert_fqdn_to_dns_name()</code> does the reverse: it converts a null-terminated
1039 string in FQDN format to bytes in DNS format.</p>

1368 <h1>6. Examples</h1>
1369
1370 <p>This section gives examples of code that calls the API to do many common tasks.
1371 The purpose of the code here is to give application developers a quick hands-on
1372 demo of using the API.</p>
1373
1374 <p>Note that the examples here all use getdns_libevent.h as the include that will call in the API
1375 code as well as calling in libevent as the event library. They also use
1376 <code>getdns_context_set_libevent_base()</code> as the name of the function to set the event base in
1377 the DNS context. If you are using a different event library, you will of course use a different

1658 <h2>6.3 Get Addresses for a Domain Name And Their Associated DNSSEC Validation Status</h2>
1659
1660 <p>This example shows how to check for secure DNSSEC results using the
1661 <code>dnssec_return_status</code> extension. In the innermost loop of the
1662 callback function, add a check for the DNSSEC status. It shows how to add two
1663 extensions to the <code>extensions</code> argument of the call.</p>
1664
1665 <pre>
1666 struct getdns_dict * this_extensions = getdns_dict_create();
1667 this_ret = getdns_dict_set_int(this_extensions, "return_both_v4_and_v6", GETDNS_EXTENSION_TRUE);
1668 this_ret = getdns_dict_set_int(this_extensions, "dnssec_return_status", GETDNS_EXTENSION_TRUE);
1669 . . .
1670 if (*this_type == GETDNS_RRTYPE_A)
1671 {
1672 uint32_t * this_dnssec_status;
1673 this_ret = getdns_dict_get_int(this_rdata, "dnssec_status", this_dnssec_status);
1674 if (&amp;this_dnssec_status != GETDNS_DNSSEC_SECURE)
1675 {
1676 // Log the DNSSEC status somewhere
1677 }
1678 else
1679 {
1680 // Deal with the record however you were going to
1681 }
1682 }
1683 . . .
1684 </pre>
1685
1686 <p>You can put the DNSSEC status check outside the check for the particular type of record you care about, but
1687 you will then get log messages for bad status on records you might not care about as well.</p>
1688
1689 <h2>6.4 Using the API Synchronously with <code>getdns_sync_request()</code></h2>
1690
1691 <p>This example is the same as the earlier examples, but uses <code>getdns_general_sync()</code>
1692 and thus does not use the async code. Note that the processing of the answers is essentially the same
1693 as it is for the synchronous example, it is just done in <code>main()</code>.</p>

1787 <h1>7. More Helper Functions</h1>
1788
1789 <p>The following two functions convert individual labels of IDNs between their Unicode
1790 encoding and their ASCII encoding. They follow the rules for IDNA 2008 described in
1791 RFC 5890-5892.</p>
1792 <div class=forh>char *

1796 </div>
1797 <div class=forh>char *
1798 getdns_convert_alabel_to_ulabel(
1799 char *alabel
1800 );
1801 </div>
1802
1803 <p>If an application wants the API do perform DNSSEC validation without using the extensions, it
1804 can use the <code>getdns_validate_dnssec()</code> helper function.</p>
1805 <div class=forh>getdns_return_t
1806 getdns_validate_dnssec(
1807 struct getdns_bindata *record_to_validate,
1808 struct getdns_list *bundle_of_support_records,
1809 struct getdns_list *trust_anchor_rdatas
1810 );
1811 </div>
1812 <p class=cont>The <code>record_to_validate</code> is the resource record being validated. The API
1813 will use the resource records in <code>bundle_of_support_records</code> and the RDATAs in the
1814 <code>trust_ancor_rdatas</code> as trust anchors. The function returns one of
1815 <code>GETDNS_DNSSEC_SECURE</code>, <code>GETDNS_DNSSEC_BOGUS</code>,
1816 <code>GETDNS_DNSSEC_INDETERMINATE</code>, or <code>GETDNS_DNSSEC_INSECURE</code>.</p>
1817
1818 <p>There are two functions that help process data:</p>
1819
1820 <div class=forh>
1821 char *
1822 getdns_pretty_print_dict(
1823 struct getdns_dict *some_dict
1824 );
1825 </div>
1826 <p class=cont>This returns a string that is the nicely-formatted version
1827 of the dict and all of the named elements in it.</p>
1828
1829 <div class=forh>
1830 char *
1831 getdns_display_ip_address(
1832 struct getdns_bindata *bindata_of_ipv4_or_ipv6_address
1833 );
1834 </div>
1835 <p class=cont>This returns a string that is the nicely-formatted version
1836 of the IPv4 or IPv6 address in it. The API determines they type of address
1837 by the length given in the bindata.</p>
1838
1839 <h1>8. <a id="Contexts">DNS Contexts</a></h1>
1840
1841 <p>Many calls in the DNS API require a DNS context. A DNS
1842 context contains the information that the API needs in order to process DNS calls, such as the
1843 locations of upstream DNS servers, DNSSEC trust anchors, and so on. The internal structure of the
1844 DNS context is opaque, and might be different on each OS. When a context is passed to any function,
1845 it must be an allocated context; the context must not be NULL.</p>
1846
1847 <p>A typical application using this API doesn't need to know anything about contexts. Basically,
1848 the application creates a default context, uses it in the functions that require a context, and
1849 then deallocates it when done. Context manipulation is available for more DNS-aware programs,
1850 but is unlikely to be of interest to applications that just want the results of lookups for
1851 A, AAAA, SRV, and PTR records.</p>
1852
1853 <p>It is expected that contexts in implementations of the API will not necessarily be thread-safe,
1854 but they will not be thread-hostile. A context should not be used by multiple threads: create a new
1855 context for use on a different thread. It is just fine for an application to have many contexts,
1856 and some DNS-heavy applications will certainly want to have many even if the application uses
1857 a single thread.</p>
1858
1859 <p>See <a href="#ContextInitial">above</a> for the method for creating and destroying
1860 contexts. When the context is used in the API for the first time and <code>set_from_os</code> is
1861 <code>1</code>, the API starts replacing some of the values with values from the OS, such as
1862 those that would be found in res_query(3), /etc/resolv.conf, and so on, then proceeds with the new
1863 function. Some advanced users will not want the API to change the values to the OS's defaults; if
1864 <code>set_from_os</code> is <code>0</code>, the API will not do any updates to the initial
1865 values based on changes in the OS. For example, this might be useful if the API is acting
1866 as a stub resolver that is using a specific upstream recursive resolver chosen by the
1867 application, not the one that might come back from DHCP.</p>
1868
1869 <h2>8.1 Updating the Context Automatically</h2>
1870
1871 <p>The context returned by <code>getdns_context_create()</code> is updated by the API by default,
1872 such as when changes are made to /etc/resolv.conf. When there is a change, the callback function
1873 that is set in <code>getdns_context_set_context_update_callback()</code> (described below) is
1874 called.</p>
1875
1876 <p>Many of the defaults for a context come from the operating system under which the API is running.
1877 In specific, it is important that the implementation should try to replicate as best as possible the
1878 logic of a local <code>getaddrinfo()</code> when creating a new context. This includes making
1879 lookups in WINS for NetBIOS, mDNS lookups, nis names, and any other name lookup that
1880 <code>getaddrinfo()</code> normally does automatically. The API should look at nsswitch, the Windows
1881 resolver, and so on.</p>
1882
1883 <p>In the function definitions below, the choice listed <span class=default>in bold</span> is the one used
1884 for the API default context.</p>
1885
1886 <h2>8.2 Updating the Context Manually</h2>
1887
1888 <p>Setting specific values in a context are done with value-specific
1889 functions shown here. The setting functions all return either <code>GETDNS_RETURN_GOOD</code> for
1890 success, <code>GETDNS_RETURN_BAD_CONTEXT</code> for trying to set a type with a value that
1891 is not allowed, or <code>GETDNS_RETURN_CONTEXT_UPDATE_FAIL</code> for a failure to update the context.</p>
1892
1893 <p>An application can be notified when the context is changed.</p>
1894
1895 <div class=forh>
1896 getdns_return_t
1897 getdns_context_set_context_update_callback(
1898 struct getdns_context *context,
1899 void (*value)(struct getdns_context *context, uint16_t changed_item)
1900 );</div>
1901 <p class=cont>The value is a pointer to the callback function that will be
1902 called when any context is changed. Such changes might be from automatic
1903 changes from the API (such as changes to /etc/resolv.conf), or might be from any of the
1904 API functions in this section being called. The second argument to the callback function
1905 specifies which of the context changed; the context codes are listed
1906 <a href="#ContextCodes">later in this document</a>.</p>

1922 Some implementations of this API are expected to also be able to act as stub resolvers.
1923 If an
1924 implementation of this API is only able to act as a recursive resolver, a call to

2066 <h2>8.7 Context Specific to Stub Resolvers</h2>
2067
2068 <p>An application can change the quering mechanism of a context to be to act as a stub
2069 resolver. Such an application might first get the default information to make this change
2070 from the operating system, probably through DHCP.</p>
2071
2072 <p>Note that if a context is changed to being a stub resolver, this automatically prevents the application
2073 from using the extenstions for DNSSEC. An application that wants to both do DNSSEC and stub resolution
2074 must do its own DNSSEC processing, possibly with the <code>getdns_validate_dnssec()</code> function.</p>

2082 <p class=cont>The list of dicts define where a stub resolver will send queries. Each dict contains
2083 at least two names: <code>address_type</code> (whose value is a bindata; it is currently either
2084 "IPv4" or "IPv6") and <code>address_data</code> (whose value is a bindata). It might also contain
2085 <code>port</code> to specify which port to use to contact these DNS servers; the default is 53. If
2086 the stub and a recursive resolver both support TSIG (RFC 2845), the <code>upstream_list</code> entry
2087 can also contain <code>tsig_algorithm</code> (a bindata) that is the name of the TSIG hash
2088 algorithm, and <code>tsig_secret</code> (a bindata) that is the TSIG key.</p>

2198 <h1>9. The Generated Files</h1>
2199
2200 <p>There is <a href="getdns-0.371.tgz">a tarball</a> that includes the .h files,
2201 the examples, and so on. The examples all make, even though there is no API implementation, based
2202 on a pseudo-implementation in the tarball; see make-examples-PLATFORM.sh. Note that this currently builds fine
2203 on the Macintosh and Ubuntu; help is definitely appreciated on making the build process
2204 work on more platforms if it fails there.</p>
2205
2206 <h1>10. <a id="Commentary">Commentary</a></h1>
2207
2208 <p>The following description of the API may be of value to those who might implement the design, and
2209 those who are using an implementation of the design.</p>
2210
2211 <h2>10.1 API Design Considerations</h2>
2212
2213 <p>The genesis of this DNS API design was seeing other DNS API designs flounder. There are other
2214 DNS APIs already available (such as draft-hayatnagarkar-dnsext-validator-api, as well
2215 as DNSSEC APIs in BIND and Unbound), but there has been very little uptake of them. In talking to
2216 application developers, there was a consistent story: that they felt that the APIs were developed by and
2217 for DNS people, not applications developers.</p>
2218
2219 <p>This API design comes from talking to a small handful of applications developers about what they
2220 would want to see in a modern DNS API. Now that the API is public, it would be great to hear from many
2221 more application developers about whether it would meet their needs if it was implemented. My goal
2222 is to create a design that is a natural follow-on to <code>getaddrinfo()</code> that has all the
2223 capabilities that most application developers might want now or in the next few years: access to all
2224 types of DNS records (including those which are yet to be defined), full DNSSEC awareness, IDN
2225 handling, and parity for IPv4 and IPv6 addresses.</p>
2226
2227 <p>Note that this is just a design for a new API: there is no implementation of the design yet, but
2228 at least one is being worked on. The process of designing the API without implementing it at the
2229 same time has the huge advantage that major design changes could be made without any worry about
2230 "but we already coded it the other way". In the early revisions of this document, many fundamental
2231 design choices changed over and over, and even bike-shedding-like changes were allowed because they
2232 didn't involve any programming effort.</p>
2233
2234 <p>This work was done independently, not through the IETF because the IETF generally doesn't take on
2235 API work, and has explicitly avoided DNS API work in the past.</p>
2236
2237 <p>This API design has a Creative Commons license so that it can be
2238 used widely by potential API implementers. This also allows other people who want to fork the design
2239 to do so cleanly. Of course, any implementation of this API can choose whatever kind of license the
2240 API implementer wishes, but it would be fabulous if one or more such implementations had Creative
2241 Commons or BSD-ish licenses.</p>
2242
2243 <p>The API relies heavily on C macros and hopefully has no magic numbers.</p>
2244
2245 <h2>10.2 API Implementation Considerations</h2>
2246
2247 <p>All implementations of this API must act as recursive resolvers, and some might choose not to be
2248 able to act as stub resolvers. Note that all implementations of this API must be DNSSEC validators.</p>
2249
2250 <p>Because there are many C event libraries available, and they have different calling routines,
2251 it is the implementation of an API that determines which event library is used. This is certainly
2252 not optimal for C programmers, but they appear to have gotten used to is so far. All implementations
2253 of this API must support synchronous calls with <code>getdns_sync_request()</code>.</p>
2254
2255 <p>Versions are differentiated by version strings instead of version numbers. The version string for
2256 this API is "getdns April 2013". Each implementation is free to set the implementation string as it
2257 feels fit.</p>
2258
2259 <p>The API's .h file contains a macro called <code>GETDNS_COMPILATION_COMMENT</code>. This can be useful
2260 to an application which will use the API because it can check the string without calling any
2261 functions. Each time the API implementation is compiled, this string should be updated with unique
2262 information about the implementation build.</p>
2263
2264 <p>The implementation of both the async and sync <code>getdns</code> functions will
2265 copy all the values of the parameters into local memory, in case the application changes or
2266 deallocates them.</p>

0 The programs in this directory are intended to provide a regression
1 test suite - we should be adding tests here as we build the package.
2
3 When building unit tests one approach that makes regression testing
4 easy is to generate canonical output and maintain that with the
5 code. Changes to the code should produce output that matches the
6 canonical output, if it doesn't then the developer needs to look at
7 the differences to determine whether something broke or is fixed. Once
8 the new output is verified it can replace the canonical output.
9
10 A typical flow might be illustrated via tests_list:
11 - build tests_list (an executable linked against the library)
12 - run the regression tests
13 ./tests_list > tests_list.out
14 - compare output to canonical output
15 diff tests_list.out tests_list.can > tests_list.res
16 - if there are any diffs then a change affected the output
17 - verify the new output and copy it to tests_list.can
18 - commit the new canonical output to the repository
19
20 Some of the tests that remain to be implemented:
21 - memory leak testing integrated into the test progs
