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. 257 </p> 258 <a name="anchor2"></a><br /><hr /> 259 <table summary="layout" cellpadding="0" cellspacing="2" class="TOCbug" align="right"><tr><td class="TOCbug"><a href="#toc"> TOC </a></td></tr></table> 260 <a name="rfc.section.2"></a><h3>2. 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. 327 </p> 328 <a name="anchor3"></a><br /><hr /> 329 <table summary="layout" cellpadding="0" cellspacing="2" class="TOCbug" align="right"><tr><td class="TOCbug"><a href="#toc"> TOC </a></td></tr></table> 330 <a name="rfc.section.3"></a><h3>3. 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., “Dynamic Host Configuration Protocol,” March 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., “Dynamic Host Configuration Protocol,” March 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. 408 </p> 409 <a name="anchor4"></a><br /><hr /> 410 <table summary="layout" cellpadding="0" cellspacing="2" class="TOCbug" align="right"><tr><td class="TOCbug"><a href="#toc"> TOC </a></td></tr></table> 411 <a name="rfc.section.3.1"></a><h3>3.1. 412 Ethernet Protocol References</h3> 413 414 <p>ISC DHCP Implements Ethernet Version 2 ("DIX"), which is a variant 415 of IEEE 802.2.

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. 508 </p> 509 <p><a class='info' href='#RFC2132'>RFC2132<span> (</span><span class='info'>Alexander, S. and R.

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. 519 </p> 520 <a name="anchor13"></a><br /><hr /> 521 <table summary="layout" cellpadding="0" cellspacing="2" class="TOCbug" align="right"><tr><td class="TOCbug"><a href="#toc"> TOC </a></td></tr></table> 522 <a name="rfc.section.5.2"></a><h3>5.2. 523 DHCPv4 Option References</h3> 524 525 <p><a class='info' href='#RFC2241'>RFC2241<span> (</span><span class='info'>Provan, D., “DHCP Options for Novell Directory Services,” November 1997.</span><span>)</span></a> [RFC2241] defines options for 526 Novell Directory Services. 527 </p> 528 <p><a class='info' href='#RFC2242'>RFC2242<span> (</span><span class='info'>Droms, R. and K.

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.

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.
