7 | This is a development snapshot of Version 3 of the Internet Software |
8 | Consortium DHCP Distribution. | |

12 | Version 3 of the ISC DHCP Distribution includes the following features |
13 | that are new since version 2.0: | |
29d5553a | 14 | |
da411127 TL |
15 | - DHCP Failover Protocol support |
16 | - OMAPI, an API for accessing and modifying the DHCP server and | |
17 | client state. | |
18 | - Conditional behaviour | |
19 | - Storing arbitrary information on leases | |
20 | - Address pools with access control | |
21 | - Client classing | |
22 | - Address allocation restriction by class | |
23 | - Relay agent information option support | |
24 | - Dynamic DNS updates | |
25 | - Many bug fixes, performance enhancements, and minor new DHCP | |
26 | protocol features. | |

6d779c72 TL |
28 | This release has been beta tested quite thorougly, and we think it is |
29 | substantially more robust at this time than 2.0pl5. The release | |
30 | candidate is expected to be free of serious bugs, but it's called a | |
31 | release candidate because we want people to try it and find any last | |
32 | real problems before we call it done. We do not expect to add | |
33 | anything other than documentation and any remaining bug fixes to the | |
34 | 3.0 release. | |
35 | ||
36 | The 3.0 Release Candidate 1 lease file is not backwards compatible | |
f67f6c4a TL |
37 | with the 3.0 Beta 1 lease file, so if you have to go back, you will |
38 | have to convert your lease files back to the 3.0 Beta 1 format - if | |
87784777 | 39 | you try to run a 3.0 Beta 1 server on a 3.0 lease file, it will |
6d779c72 TL |
40 | cheerfully delete all your leases. |
41 | ||
42 | If you are running 3.0 beta 1 and are doing dynamic DNS updates, the | |
43 | lease file is no longer forward-compatible to 3.0 final. A script | |
44 | has been provided to convert 3.0b1 lease files. This is in | |
45 | contrib/3.0b1-lease-convert. | |

47 | For information on how to install, configure and run this software, |
48 | as well as how to find documentation and report bugs, please consult | |
49 | the README file. | |
50 | ||
da411127 TL |
51 | The Dynamic DNS Update support is a descendent of an implementation |
52 | done by Lans Carstensen and Brian Dols at Rose-Hulman Institute of | |
de57e64b TL |
53 | Technology, Jim Watt at Applied Biosystems, Irina Goble at Integrated |
54 | Measurement Systems, Igor Sharfmesser at Kazakh Telecom, and Brian | |
55 | Murrell at BC Tel Advanced Communications. I'd like to express my | |
56 | thanks to all of these good people here, both for working on the code | |
57 | and for prodding me into improving it. | |
58 | ||
87784777 TL |
59 | Changes since 3.0 Release Candidate 1 |
60 | ||
61 | - Fix a small bug in binary-to-ascii, thanks to H. Peter Anvin of | |
62 | Transmeta. | |
63 | ||
64 | - Fix a memory smash that happens when fixed-address leases are used. | |
65 | ANY SITE AT WHICH FIXED-ADDRESS STATEMENTS ARE BEING USED SHOULD | |
66 | UPGRADE IMMEDIATELY. This has been a long-standing bug - thanks to | |
67 | Alvise Nobile for discovering it and helping me to find it! | |
68 | ||
69 | - There is a known problem with the DHCP server doing failover on | |
70 | Compaq Alpha systems. This patchlevel is not a release candidate | |
71 | because of this bug. The bug should be straightforward to fix, so | |
72 | a new release candidate is expected shortly. | |
73 | ||
74 | - There is a known problem in the DDNS update code that is probably a | |
75 | bug, and is not, as far as we know, fixed in this patchlevel. | |
76 | ||
77 | ||
6d779c72 TL |
78 | Changes since 3.0 Beta 2 Patchlevel 24 |
79 | ||
80 | - Went over problematic failover state transitions and made them all | |
81 | work, so that failover should now much less fragile. | |
82 | ||
83 | - Add some dhcpctl and omapi documentation | |
84 | ||
85 | - Fix compile errors when compiling with unusual predefines. | |
86 | ||
87 | - Make Token Ring work on Linux 2.4 | |
88 | ||
89 | - Fix the Digital Unix BPF_WORDALIGN bug. | |
90 | ||
91 | - Fix some dhcp client documentation errors. | |
92 | ||
93 | - Update some parts of the README file. | |
94 | ||
95 | - Support GCC on SCO. | |
96 | ||
de57e64b TL |
97 | Changes since 3.0 Beta 2 Patchlevel 23 |
98 | ||
99 | - Fix a bug in the DNS update code where a status code was not being | |
100 | checked. This may have been causing core dumps. | |
101 | ||
102 | - When parsing the lease file, if a lease declaration includes a | |
103 | billing class statement, and the lease already has a billing class, | |
104 | unbill the old class. | |
105 | ||
106 | - When processing failover transactions, where acks will be deferred, | |
107 | process the state transition immediately. | |
108 | ||
109 | - Don't try to use the new SIOCGIFCONF buffer size detection code on | |
110 | Linux 2.0, which doesn't provide this functionality. | |
111 | ||
112 | - Apply a patch suggested by Tuan Uong for a problem in dlpi.c. | |
113 | ||
114 | - Fix a problem in using the which command in the configure script. | |
115 | ||
116 | - Fix a parse error in the client when setting up an omapi listener. | |
117 | ||
118 | - Document the -n and -g flags to the client. | |
119 | ||
120 | - Make sure there is always a stdin and stdout on startup. This | |
121 | prevents shell scripts from accidentally writing error messages into | |
122 | configuration files that happen to be opened as stderr. | |
123 | ||
124 | - If an interface is removed, the client will now notice that it is | |
125 | gone rather than spinning. This has only been tested on NetBSD. | |
126 | ||
127 | - The client will attempt to get an address even if it can't create a | |
128 | lease file. | |
129 | ||
130 | - Don't overwrite tracefiles. | |
131 | ||
132 | - Fix some memory allocation bugs in failover. | |
2aa36519 | 133 | |
140158d3 TL |
134 | Changes since 3.0 Beta 2 Patchlevel 22 |
135 | ||
136 | - Apply some patches suggested by Cyrille Lefevre, who is maintaining | |
137 | the FreeBSD ISC DHCP Distribution port. | |
138 | ||
139 | - Fix a core dump in DHCPRELEASE. | |
140 | ||
3a395e60 TL |
141 | Changes since 3.0 Beta 2 Patchlevel 21 |
142 | ||
143 | - This time for sure: fix the spin described in the changes for pl20. | |
144 | ||
fc74dd0c TL |
145 | Changes since 3.0 Beta 2 Patchlevel 20 |
146 | ||
147 | - Fix a problem with Linux detecting large numbers of interfaces (Ben) | |
148 | ||
149 | - Fix a memory smash in the quotify code, which was introduced in | |
150 | pl19. | |
151 | ||
152 | - Actually fix the spin described in the changes for pl20. The | |
153 | previous fix only partially fixed the problem - enough to get it | |
154 | past the regression test. | |
155 | ||
ed5ee591 TL |
156 | Changes since 3.0 Beta 2 Patchlevel 19 |
157 | ||
158 | - Fix a bug that could cause the server to abort if compiled with | |
159 | POINTER_DEBUG enabled. | |
160 | ||
161 | - Fix a bug that could cause the server to spin when responding to a | |
162 | DHCPREQUEST. | |
163 | ||
164 | - Apply Joost Mulders' suggested patches for DLPI on x86. | |
165 | ||
166 | - Support NUL characters in quoted strings. | |
167 | ||
168 | - Install unformatted man pages on SunOS. | |
169 | ||
b3fad8ac TL |
170 | Changes since 3.0 Beta 2 Patchlevel 18 |
171 | ||
3350f5b7 TL |
172 | - Allow the server to be placed in partner-down state using OMAPI. |
173 | (Damien Neil) | |
174 | ||
175 | - Implement omshell, which can be used to do arbitrary things to the | |
176 | server (in theory). (Damien Neil) | |
177 | ||
178 | - Fix a case where if a client had two different leases the server could | |
179 | actually dereference the second one when it hadn't been referenced, | |
180 | leading to memory corruption and a core dump. (James Brister) | |
181 | ||
182 | - Fix a case where a client could request the address of another client's | |
183 | lease, but find_lease wouldn't detect that the other client had it, and | |
184 | would attempt to allocate it to the client, resulting in a lease conflict | |
185 | message. | |
186 | ||
187 | - Fix a case where a client with more than one client identifier could be | |
188 | given a lease where the hardware address was correct but the client | |
189 | identifier was not, resulting in a lease conflict message. | |
190 | ||
191 | - Fix a problem where the server could write out a colon-seperated | |
192 | hex list as a value for a variable, which would then not parse. | |
193 | The fix is to always write strings as quoted strings, with any | |
194 | non-printable characters quoted as octal escape sequences. So | |
195 | a file written the old way still won't work, but new files written | |
196 | this way will work. | |
197 | ||
b3fad8ac TL |
198 | - Fix documentation for sending non-standard options. |
199 | ||
200 | - Use unparsable names for unknown options. WARNING: this will | |
201 | break any configuration files that use the option-nnn convention. | |
202 | If you want to continue to use this convention for some options, | |
203 | please be sure to write a definition, like this: | |
204 | ||
205 | option option-nnn code nnn = string; | |
206 | ||
207 | You can use a descriptive name instead of option-nnn if you like. | |
208 | ||
209 | - Fix a problem where we would see a DHCPDISCOVER/DHCPOFFER/ | |
210 | DHCPREQUEST/DHCPACK/DHCPREQUEST/DHCPNAK sequence. This was the | |
211 | result of a deceptively silly bug in supersede_lease. | |
212 | ||
213 | - Fix client script exit status check, according to a fix supplied by | |
214 | Hermann Lauer. | |
215 | ||
216 | - Fix an endianness bug in the tracefile support, regarding ICMP | |
217 | messages. | |
218 | ||
3350f5b7 TL |
219 | - Fix a bug in the client where the medium would not work correctly if |
220 | it contained quoted strings. | |
221 | ||
b3fad8ac TL |
222 | ** there was no pl17 ** |
223 | ||
e6d30fd6 TL |
224 | Changes since 3.0 Beta 2 Patchlevel 16 |
225 | ||
6da9db9d TL |
226 | - Add support for transaction tracing. This allows the state of the |
227 | DHCP server on startup, and all the subsequent transactions, to be | |
228 | recorded in a file which can then be played back to reproduce the | |
229 | behaviour of the DHCP server. This can be used to quickly | |
230 | reproduce bugs that cause core dumps or corruption, and also for | |
231 | tracking down memory leaks. | |
232 | ||
233 | - Incorporate some bug fixes provided by Joost Mulders for the DLPI | |
234 | package which should clear up problems people have been seeing on | |
235 | Solaris. | |
236 | ||
237 | - Fix bugs in the handling of options stored as linked lists (agent | |
238 | options, fqdn options and nwip options) that could cause memory | |
239 | corruption and core dumps. | |
240 | ||
241 | - Fix a bug in DHCPREQUEST handling that resulted in DHCPNAK messages | |
242 | not being send in some cases when they were needed. | |
243 | ||
244 | - Make the lease structure somewhat more compact. | |
245 | ||
246 | - Make initial failover startup *much* faster. This was researched | |
247 | and implemented by Damien Neil. | |
248 | ||
249 | - Add a --version flag to all executables, which prints the program | |
250 | name and version to standard output. | |
251 | ||
252 | - Don't rewrite the lease file every thousand leases. | |
253 | ||
e6d30fd6 TL |
254 | - A bug in nit.c for older SunOS machines was fixed by a patch sent in |
255 | by Takeshi Hagiwara. | |
256 | ||
6da9db9d TL |
257 | - Fix a memory corruption bug in the DHCP client. |
258 | ||
259 | - Lots of documentation updates. | |
260 | ||
261 | - Add a feature allowing environment variables to be passed to the | |
262 | DHCP client script on the DHCP client command line. | |
263 | ||
264 | - Fix client medium support, which had been broken for some time. | |
265 | ||
266 | - Fix a bug in the DHCP client initial startup backoff interval, which | |
267 | would cause two DHCPDISCOVERS to be sent back-to-back on startup. | |
268 | ||
269 | ||
af49fdff TL |
270 | Changes since 3.0 Beta 2 Patchlevel 15 |
271 | ||
272 | - Some documentation tweaks. | |
273 | ||
274 | - Maybe fix a problem in the DLPI code. | |
275 | ||
276 | - Fix some error code space inconsistencies in ddns update code. | |
277 | ||
278 | - Support relay agents that intercept unicast DHCP messages to stuff | |
279 | agent options into them. | |
280 | ||
281 | - Fix a small memory leak in the relay agent option support code. | |
282 | ||
c5b569f8 TL |
283 | - Fix a core dump that would occur if a packet was sent with no |
284 | options. | |
285 | ||
754ae3e9 TL |
286 | Changes since 3.0 Beta 2 Patchlevel 14 |
287 | ||
288 | - Finish fixing a long-standing bug in the agent options code. This | |
289 | was causing core dumps and failing to operate correctly - in | |
290 | particular, agent option stashing wasn't working. Agent option | |
291 | stashing should now be working, meaning that agent options can be | |
292 | used in class statements to control address allocation. | |
293 | ||
294 | - Fix up documentation. | |
295 | ||
296 | - Fix a couple of small memory leaks that would have added up | |
297 | significantly in a high-demand situation. | |
298 | ||
299 | - Add a log-facility configuration parameter. | |
300 | ||
301 | - Fix a compile error on some older operating systems. | |
302 | ||
303 | - Add the ability in the client to execute certain statements before | |
304 | transmitting packets to the server. Handy for debugging; not much | |
305 | practical use otherwise. | |
306 | ||
307 | - Don't send faked-out giaddr when renewing or bound - again, useful | |
308 | for debugging. | |
309 | ||
2f2e7960 TL |
310 | Changes since 3.0 Beta 2 Patchlevel 13 |
311 | ||
312 | - Fixed a problem where the fqdn decoder would sometimes try to store | |
313 | an option with an (unsigned) negative length, resulting in a core | |
314 | dump on some systems. | |
315 | ||
316 | - Work around the Win98 DHCP client, which NUL-terminates the FQDN | |
317 | option. | |
318 | ||
319 | - Work around Win98 and Win2k clients that will claim they want to do | |
320 | the update even when they don't have any way to do it. | |
321 | ||
322 | - Fix some log messages that can be printed when failover is operating | |
323 | that were not printing enough information. | |
324 | ||
325 | - It was possible for a DHCPDISCOVER to get an allocation even when | |
326 | the state machine said the server shouldn't be responding. | |
327 | ||
328 | - Don't load balance DHCPREQUESTs from clients in RENEWING and | |
329 | REBINDING, since in RENEWING, if we heard it, it's for us, and in | |
330 | REBINDING, the client wouldn't have got to REBINDING if its primary | |
331 | were answering. | |
332 | ||
333 | - When we get a bogus state lease binding state transition, don't do | |
334 | the transition. | |
335 | ||
336 | ||
66e98927 TL |
337 | Changes since 3.0 Beta 2 Patchlevel 12 |
338 | ||
339 | - Fixed a couple of silly compile errors. | |
340 | ||
a1e2e3d6 TL |
341 | Changes since 3.0 Beta 2 Patchlevel 11 |
342 | ||
343 | - Albert Herranz tracked down and fixed a subtle bug in the base64 | |
344 | decoder that would prevent any key with an 'x' in its base64 | |
345 | representation from working correctly. | |
346 | ||
347 | - Thanks to Chris Cheney and Michael Sanders, we have a fix for the | |
348 | hang that they both spotted in the DHCP server - when | |
349 | one-lease-per-client was set, the code to release the "other" lease | |
350 | could spin. | |
351 | ||
352 | - Fix a problem with alignment of the input buffer in bpf in cases | |
353 | where two packets arrive in the same bpf read. | |
354 | ||
355 | - Fix a problem where the relay agent would crash if you specified an | |
356 | interface name on the command line. | |
357 | ||
358 | - Add the ability to conditionalize client behaviour based on the | |
359 | client state. | |
360 | ||
361 | - Add support for the FQDN option, and added support for a new way of | |
362 | doing ddns updates (ddns update style interim) that allows more than | |
363 | one DHCP server to update the DNS for the same network(s). This | |
364 | was implemented by Damien Neil with some additional functionality | |
365 | added by Ted Lemon. | |
366 | ||
367 | - Damien added a "log" statement, so that the configuration file can | |
368 | be made to log debugging information and other information. | |
369 | ||
370 | - Fixed a bug that caused option buffers not to be terminated with an | |
371 | end option. | |
372 | ||
373 | - Fixed a long-standing bug in the support for option spaces where the | |
374 | options are stored as an ordered list rather than in a hash table, | |
375 | which could theoretically result in memory pool corruption. | |
376 | ||
377 | - Prevent hardware declarations with no actual hardware address from | |
378 | being written as something unparsable, and behave correctly in the | |
379 | face of a null hardware address on input. | |
380 | ||
381 | - Allow key names to be FQDNs, and qualify the algorithm name if it is | |
382 | specified unqualified. | |
383 | ||
384 | - Modify the DDNS update code so that it never prints the "resolver | |
385 | failed" message, but instead says *why* the resolver failed. | |
386 | ||
387 | - Officially support the subnet selection option, which now has an | |
388 | RFC. | |
389 | ||
390 | - Fix a build bug on MacOS X. | |
391 | ||
392 | - Allow administrator to disable ping checking. | |
393 | ||
394 | - Clean up dhcpd.conf documentation and add more information about how | |
395 | it works. | |
396 | ||
6c68ec36 TL |
397 | Changes since 3.0 Beta 2 Patchlevel 10 |
398 | ||
399 | - Fix a bug introduced during debugging (!) and accidentally committed | |
400 | to CVS. | |
401 | ||
9fd337e7 TL |
402 | Changes since 3.0 Beta 2 Patchlevel 9 |
403 | ||
404 | - Fix DHCP client handling of vendor encapsulated options. | |
405 | ||
406 | - Fix a bug in the handling of relay agent information options introduced | |
407 | in patchlevel 9. | |
408 | ||
409 | - Stash agent options on client leases by default, and use the stashed | |
410 | options at renewal time. | |
411 | ||
412 | - Add the ability to test the client's binding state in the client | |
413 | configuration language. | |
414 | ||
415 | - Fix a core dump in the DNS update code. | |
416 | ||
417 | - Fix some expression evaluation bugs that were causing updates to be | |
418 | done when no client hostname was received. | |
419 | ||
420 | - Fix expression evaluation debugging printfs. | |
421 | ||
422 | - Teach pretty_print_option to print options in option spaces other than | |
423 | the DHCP option space. | |
424 | ||
425 | - Add a warning message if the RHS of a not is not boolean. | |
426 | ||
427 | - Never select for more than a day, because some implementations of | |
428 | select will just fail if the timeout is too long (!). | |
429 | ||
430 | - Fix a case where a DHCPDISCOVER from an unknown network would be | |
431 | silently dropped. | |
432 | ||
433 | - Fix a bug where if a client requested an IP address for which a different | |
434 | client had the lease, the DHCP server would reallocate it anyway. | |
435 | ||
436 | - Fix the DNS update code so that if the client changes its name, the DNS | |
437 | will be correctly updated. | |
438 | ||
3922772a TL |
439 | Changes since 3.0 Beta 2 Patchlevel 8 |
440 | ||
441 | - Oops, there was another subtle math error in the header-length | |
442 | bounds-checking. | |
443 | ||
444 | Changes since 3.0 Beta 2 Patchlevel 7 | |
848c2547 TL |
445 | |
446 | - Oops, forgot to byte-swap udp header length before bounds-checking it. | |
447 | ||
3922772a | 448 | Changes since 3.0 Beta 2 Patchlevel 6 |
0f6045f8 | 449 | |
f8572308 TL |
450 | - Fix a possible DoS attack where a client could cause the checksummer |
451 | to dump core. This was a read, not a write, so it shouldn't be | |
452 | possible to exploit it any further than that. | |
453 | ||
454 | - Implement client- and server-side support for using the Client FQDN | |
455 | option. | |
456 | ||
457 | - Support for other option spaces in the client has been added. This | |
458 | means that it is now possible to define a vendor option space on the | |
459 | client, request options in that space from the server (which must | |
460 | define the same option space), and then use those options in the | |
461 | client. This also allows NWIP and Client FQDN options to be used | |
462 | meaningfully. | |
463 | ||
464 | - Add object initializer support. This means that objects can now be | |
465 | initialized to something other than all-zeros when allocated, which | |
466 | makes, e.g., the interface object support code a little more robust. | |
467 | ||
468 | - Fix an off-by-one bug in the host stuffer. This was causing host | |
469 | deletes not the work, and may also have been causing OMAPI | |
470 | connections to get dropped. Thanks to James Brister for tracking | |
471 | this one down! | |

473 | - Fixed a core dump in the interface discovery code that is triggered | |
474 | when there is no subnet declaration for an interface, but the server | |
475 | decides to continue running. Thanks to Shane Kerr for tracking | |
476 | down and fixing this problem. | |

481 | to support arbitrary-length interface lists. | |
482 | ||
483 | - Support NUL-terminated DHCP options when initializing client-script | |
484 | environment. | |
485 | ||
486 | - Fix suffix operator. | |
487 | ||
488 | - Fix NetWare/IP option parsing. | |
489 | ||
490 | - Better error/status checking in dhcpctl initialization and omapi | |
491 | connection code. | |
492 | ||

494 | ||
495 | - Fix SunOS4 and (maybe) Ultrix builds. | |
496 | ||
497 | - Fix a bug where a certain sort of incoming packet could cause a core | |
498 | dump on Solaris (and probably elsewhere). | |
499 | ||
500 | - Add some more safety checks in error logging code. | |
501 | ||
502 | - Add support for ISC_R_INCOMPLETE in OMAPI protocol connection code. | |
503 | ||
504 | - Fix relay agent so that if an interface is specified on the command | |
505 | line, the relay agent does not dump core. | |
506 | ||
507 | - Fix class matching so that match if can be combined with match or | |
508 | spawn with. | |
509 | ||
510 | - Do not allow spurious leases in the lease database to introduce | |
511 | potentially bogus leases into the in-memory database. | |
512 | ||
513 | - Fix a byte-order problem in the client hardware address type code | |
514 | for OMAPI. | |
515 | ||
516 | - Be slightly less picky about what sort of hardware addresses OMAPI | |
517 | can install in host declarations. | |

519 | Changes since 3.0 Beta 2 Patchlevel 4 |
520 | ||
521 | - Incorporated Peter Marschall's proposed change to array/record | |
522 | parsing, which allows things like the slp-agent option to be encoded | |
523 | correctly. Thanks very much to Peter for taking the initiative to | |
524 | do this, and for doing such a careful job of it (e.g., updating the | |
525 | comments)! | |
526 | ||
527 | - Added an encoding for the slp-agent option. :') | |
528 | ||
6ed7a93d TL |
529 | - Fixed SunOS 4 build. Thanks to Robert Elz for responding to my |
530 | request for help on this with patches! | |
531 | ||
532 | - Incorporated a change that should fix a problem reported by Philippe | |
533 | Jumelle where when the network connection between two servers is | |
534 | lost, they never reconnect. | |
535 | ||
536 | - Fix client script files other than that for NetBSD to actually use | |
537 | make_resolv_conf as documented in the manual page. | |
538 | ||
539 | - Fix a bug in the packet handling code that could result in a core | |
540 | dump. | |
541 | ||
542 | - Fix a bug in the bootp code where responses on the local net would | |
543 | be sent to the wrong MAC address. Thanks to Jerry Schave for | |
544 | catching this one. | |
545 | ||
490eb5e7 TL |
546 | Changes since 3.0 Beta 2 Patchlevel 3 |
547 | ||
548 | - In the DHCP client, execute client statements prior to using the values | |
549 | of options, so that the client configuration can overried, e.g., the | |
550 | lease renewal time. | |
551 | ||
552 | - Fix a reference counting error that would result in very reproducible | |
553 | failures in updates, as well as occasional core dumps, if a zone was | |
554 | declared without a key. | |
555 | ||
556 | - Fix some Linux 2.0 compilation problems. | |
557 | ||
558 | - Fix a bug in scope evaluation during execution of "on" statements that | |
559 | caused values not to be recorded on leases. | |
560 | ||
561 | - If the dhcp-max-message-size option is specified in scope, and the | |
562 | client didn't send this option, use the one specified in scope to | |
563 | determine the maximum size of the response. | |
564 | ||

565 | Changes since 3.0 Beta 2 Patchlevel 2 |
566 | ||

567 | - Fix a case where spawning subclasses were being allocated |
568 | incorrectly, resulting in a core dump. | |
569 | ||
592d8153 TL |
570 | - Fix a case where the DHCP server might inappropriately NAK a |
571 | RENEWING client. | |
572 | ||
573 | - Fix a place dhcprequest() where static leases could leak. | |
574 | ||
575 | - Include memory.h in omapip_p.h so that we don't get warnings about | |
576 | using memcmp(). | |
577 | ||
2aa36519 TL |
578 | Changes since 3.0 Beta 2 Patchlevel 1 |
579 | ||
580 | - Notice when SIOCFIGCONF returns more data than fit in the buffer - | |
581 | allocate a larger buffer, and retry. Thanks to Greg Fausak for | |
582 | pointing this out. | |
583 | ||
584 | - In the server, if no interfaces were configured, report an error and | |
585 | exit. | |
586 | ||
587 | - Don't ever record a state of 'startup'. | |
588 | ||
589 | - Don't try to evaluate the local failover binding address if none was | |
590 | specified. Thanks to Joseph Breu for finding this. |
