240 Introduction</h3>
241
242 <p>As a little historical anecdote, ISC DHCP once packaged all the
243 relevant RFCs and standards documents along with the software
244 package. Until one day when a voice was heard from one of the
245 many fine institutions that build and distribute this software...
246 they took issue with the IETF's copyright on the RFC's. It
247 seems the IETF's copyrights don't allow modification of RFC's
248 (except for translation purposes).
249 </p>
250 <p>Our main purpose in providing the RFCs is to aid in
251 documentation, but since RFCs are now available widely from many
252 points of distribution on the Internet, there is no real need to
253 provide the documents themselves. So, this document has been
254 created in their stead, to list the various IETF RFCs one might
255 want to read, and to comment on how well (or poorly) we have
256 managed to implement them.

261 Definition: Reference Implementation</h3>
262
263 <p>ISC DHCP, much like its other cousins in ISC software, is
264 self-described as a 'Reference Implementation.' There has been
265 a great deal of confusion about this term. Some people seem to
266 think that this term applies to any software that once passed
267 a piece of reference material on its way to market (but may do
268 quite a lot of things that aren't described in any reference, or
269 may choose to ignore the reference it saw entirely). Other folks
270 get confused by the word 'reference' and understand that to mean
271 that there is some special status applied to the software - that
272 the software itself is the reference by which all other software
273 is measured. Something along the lines of being "The DHCP
274 Protocol's Reference Clock," it is supposed.
275 </p>
276 <p>The truth is actually quite a lot simpler. Reference
277 implementations are software packages which were written
278 to behave precisely as appears in reference material. They
279 are written "to match reference."
280 </p>
281 <p>If the software has a behaviour that manifests itself
282 externally (whether it be something as simple as the 'wire
283 format' or something higher level, such as a complicated
284 behaviour that arises from multiple message exchanges), that
285 behaviour must be found in a reference document.
286 </p>
287 <p>Anything else is a bug, the only question is whether the
288 bug is in reference or software (failing to implement the
289 reference).
290 </p>
291 <p>This means:
292 </p>
293 <p>
294 </p>
295 <ul class="text">
296 <li>To produce new externally-visible behaviour, one must first
297 provide a reference.
298 </li>
299 <li>Before changing externally visible behaviour to work around
300 simple incompatibilities in any other implementation, one must
301 first provide a reference.
302 </li>
303 </ul><p>
304
305 </p>
306 <p>That is the lofty goal, at any rate. It's well understood that,
307 especially because the ISC DHCP Software package has not always been
308 held to this standard (but not entirely due to it), there are many
309 non-referenced behaviours within ISC DHCP.
310 </p>
311 <p>The primary goal of reference implementation is to prove the
312 reference material. If the reference material is good, then you
313 should be able to sit down and write a program that implements the
314 reference, to the word, and come to an implementation that
315 is distinguishable from others in the details, but not in the
316 facts of operating the protocol. This means that there is no
317 need for 'special knowledge' to work around arcane problems that
318 were left undocumented. No secret handshakes need to be learned
319 to be imparted with the necessary "real documentation".
320 </p>
321 <p>Also, by accepting only reference as the guidebook for ISC
322 DHCP's software implementation, anyone who can make an impact on
323 the color texture or form of that reference has a (somewhat
324 indirect) voice in ISC DHCP's software design. As the IETF RFC's
325 have been selected as the source of reference, that means everyone
326 on the Internet with the will to participate has a say.

331 Low Layer References</h3>
332
333 <p>It may surprise you to realize that ISC DHCP implements 802.1
334 'Ethernet' framing, Token Ring, and FDDI. In order to bridge the
335 gap there between these physical and DHCP layers, it must also
336 implement IP and UDP framing.
337 </p>
338 <p>The reason for this stems from Unix systems' handling of BSD
339 sockets (the general way one might engage in transmission of UDP
340 packets) on unconfigured interfaces, or even the handling of
341 broadcast addressing on configured interfaces.
342 </p>
343 <p>There are a few things that DHCP servers, relays, and clients all
344 need to do in order to speak the DHCP protocol in strict compliance
345 with <a class='info' href='#RFC2131'>[RFC2131]<span> (</span><span class='info'>Droms, R., &ldquo;Dynamic Host Configuration Protocol,&rdquo; March&nbsp;1997.</span><span>)</span></a>.
346
347 </p>
348 <ol class="text">
349 <li>Transmit a UDP packet from IP:0.0.0.0 Ethernet:Self, destined to
350 IP:255.255.255.255 LinkLayer:Broadcast on an unconfigured (no IP
351 address yet) interface.
352 </li>
353 <li>Receive a UDP packet from IP:remote-system LinkLayer:remote-system,
354 destined to IP:255.255.255.255 LinkLayer:Broadcast, again on an
355 unconfigured interface.
356 </li>
357 <li>Transmit a UDP packet from IP:Self, Ethernet:Self, destined to
358 IP:remote-system LinkLayer:remote-system, without transmitting a
359 single ARP.
360 </li>
361 <li>And of course the simple case, a regular IP unicast that is
362 routed via the usual means (so it may be direct to a local system,
363 with ARP providing the glue, or it may be to a remote system via
364 one or more routers as normal). In this case, the interfaces are
365 always configured.
366 </li>
367 </ol>
368
369 <p>The above isn't as simple as it sounds on a regular BSD socket.
370 Many unix implementations will transmit broadcasts not to
371 255.255.255.255, but to x.y.z.255 (where x.y.z is the system's local
372 subnet). Such packets are not received by several known DHCP client
373 implementations - and it's not their fault, <a class='info' href='#RFC2131'>[RFC2131]<span> (</span><span class='info'>Droms, R., &ldquo;Dynamic Host Configuration Protocol,&rdquo; March&nbsp;1997.</span><span>)</span></a>
374 very explicitly demands that these packets' IP destination
375 addresses be set to 255.255.255.255.
376 </p>
377 <p>Receiving packets sent to 255.255.255.255 isn't a problem on most
378 modern unixes...so long as the interface is configured. When there
379 is no IPv4 address on the interface, things become much more murky.
380 </p>
381 <p>So, for this convoluted and unfortunate state of affairs in the
382 unix systems of the day ISC DHCP was manufactured, in order to do
383 what it needs not only to implement the reference but to interoperate
384 with other implementations, the software must create some form of
385 raw socket to operate on.
386 </p>
387 <p>What it actually does is create, for each interface detected on
388 the system, a Berkeley Packet Filter socket (or equivalent), and
389 program it with a filter that brings in only DHCP packets. A
390 "fallback" UDP Berkeley socket is generally also created, a single
391 one no matter how many interfaces. Should the software need to
392 transmit a contrived packet to the local network the packet is
393 formed piece by piece and transmitted via the BPF socket. Hence
394 the need to implement many forms of Link Layer framing and above.
395 The software gets away with not having to implement IP routing
396 tables as well by simply utilizing the aforementioned 'fallback'
397 UDP socket when unicasting between two configured systems is
398 needed.
399 </p>
400 <p>Modern unixes have opened up some facilities that diminish how
401 much of this sort of nefarious kludgery is necessary, but have not
402 found the state of affairs absolutely resolved. In particular,
403 one might now unicast without ARP by inserting an entry into the
404 ARP cache prior to transmitting. Unconfigured interfaces remain
405 the sticking point, however...on virtually no modern unixes is
406 it possible to receive broadcast packets unless a local IPv4
407 address has been configured, unless it is done with raw sockets.

490 and procedures. ISC DHCP is not known to diverge from this document
491 in any way. There are, however, a few points on which different
492 implementations have arisen out of vagueries in the document.
493 DHCP Clients exist which, at one time, present themselves as using
494 a Client Identifier Option which is equal to the client's hardware
495 address. Later, the client transmits DHCP packets with no Client
496 Identifier Option present - essentially identifying themselves using
497 the hardware address. Some DHCP Servers have been developed which
498 identify this client as a single client. ISC has interpreted
499 RFC2131 to indicate that these clients must be treated as two
500 separate entities (and hence two, separate addresses). Client
501 behaviour (Embedded Windows products) has developed that relies on
502 the former implementation, and hence is incompatible with the
503 latter. Also, RFC2131 demands explicitly that some header fields
504 be zeroed upon certain message types. The ISC DHCP Server instead
505 copies many of these fields from the packet received from the client
506 or relay, which may not be zero. It is not known if there is a good
507 reason for this that has not been documented.

511 formatting and processing options. The document unfortunately
512 waffles to a great extent about the NULL termination of DHCP Options,
513 and some DHCP Clients (Windows 95) have been implemented that rely
514 upon DHCP Options containing text strings to be NULL-terminated (or
515 else they crash). So, ISC DHCP detects if clients null-terminate the
516 host-name option and, if so, null terminates any text options it
517 transmits to the client. It also removes NULL termination from any
518 known text option it receives prior to any other processing.

615 RR used in DNS to perform a kind of atomic locking.
616 </p>
617 <p>ISC DHCP adopted early versions of these documents, and has not
618 yet synchronized with the final standards versions.
619 </p>
620 <p>For RFCs 4702 and 4704, the 'N' bit is not yet supported. The
621 result is that it is always set zero, and is ignored if set.
622 </p>
623 <p>For RFC4701, which is used to match client identities with names
624 in the DNS as part of name conflict resolution. Note that ISC DHCP's
625 implementation of DHCIDs vary wildly from this specification.
626 First, ISC DHCP uses a TXT record in which the contents are stored
627 in hexadecimal. Second, there is a flaw in the selection of the
628 'Identifier Type', which results in a completely different value
629 being selected than was defined in an older revision of this
630 document...also this field is one byte prior to hexadecimal
631 encoding rather than two. Third, ISC DHCP does not use a digest
632 type code. Rather, all values for such TXT records are reached
633 via an MD5 sum. In short, nothing is compatible, but the
634 principle of the TXT record is the same as the standard DHCID
635 record. However, for DHCPv6 FQDN, we do use DHCID type code '2',
636 as no other value really makes sense in our context.

643 <p>The Failover Protocol defines means by which two DHCP Servers
644 can share all the relevant information about leases granted to
645 DHCP clients on given networks, so that one of the two servers may
646 fail and be survived by a server that can act responsibly.
647 </p>
648 <p>Unfortunately it has been quite some years (2003) since the last
649 time this document was edited, and the authors no longer show any
650 interest in fielding comments or improving the document.
651 </p>
652 <p>The status of this protocol is very unsure, but ISC's
653 implementation of it has proven stable and suitable for use in
654 sizable production environments.

656 <p><a class='info' href='#draft-failover'>draft-ietf-dhc-failover-12.txt<span> (</span><span class='info'>Droms, R., &ldquo;DHCP Failover Protocol,&rdquo; March&nbsp;2003.</span><span>)</span></a> [draft&#8209;failover]
657 describes the Failover Protocol. In addition to what is described
658 in this document, ISC DHCP has elected to make some experimental
659 changes that may be revoked in a future version of ISC DHCP (if the
660 draft authors do not adopt the new behaviour). Specifically, ISC
661 DHCP's POOLREQ behaviour differs substantially from what is
662 documented in the draft, and the server also implements a form of
663 'MAC Address Affinity' which is not described in the failover
664 document. The full nature of these changes have been described on
665 the IETF DHC WG mailing list (which has archives), and also in ISC
666 DHCP's manual pages. Also note that although this document
667 references a RECOVER-WAIT state, it does not document a protocol
668 number assignment for this state. As a consequence, ISC DHCP has
669 elected to use the value 254.
670 </p>
671 <p> An optimization described in the failover protocol draft
672 is included since 4.2.0a1. It permits a DHCP server
673 operating in communications-interrupted state to 'rewind' a
674 lease to the state most recently transmitted to its peer,
675 greatly increasing a server's endurance in
676 communications-interrupted. This is supported using a new
677 'rewind state' record on the dhcpd.leases entry for each
678 lease.

708 </p>
709 <p>Support for DHCPv6 was first added in version 4.0.0. The server
710 and client support only IA_NA. While the server does support multiple
711 IA_NAs within one packet from the client, our client only supports
712 sending one. There is no relay support.

727 <li>The same option space appears in DHCPv6 packets multiple times.
728 If the packet was got via a relay, then the client's packet is

731 option space" is used. Further, a client packet may contain an
732 IA_NA, which may contain an IAADDR - but really, in an abstract
