 399.	[bug]		When reloading the server with a config file
			containing a syntax error, it could catch an
			assertion failure trying to perform zone
			maintenance on, or sending notifies from,
			tentatively created zones whose	views were
			never fully configured and lacked an address 
			database and request manager.

10 11 12
 398.	[bug]		"dig" sometimes caught an assertion failure when
			using TSIG, depending on the key length.

13 14
 397.	[func]		Added utility functions dns_view_gettsig() and
			dns_view_getpeertsig().
15

16 17 18
 396.	[doc]		There is now a man page for "nsupdate" 
			in doc/man/bin/nsupdate.8.

19 20 21
 395.	[bug]		nslookup printed incorrect RR type mnemonics
			for RRs of type >= 21 [RT #237].

 394.	[bug]		Current name was not propagated via $INCLUDE.

 393.	[func]		Initial answer while loading (awl) support.
			Entry points: dns_master_loadfileinc(),
			dns_master_loadstreaminc(), dns_master_loadbufferinc().
			Note: calls to dns_master_load*inc() should be rate
			be rate limited so as to not use up all file
			descriptors.

31 32 33 34 35
 392.	[func]		Add ISC_R_FAMILYNOSUPPORT.  Returned when OS does
			not support the given address family requested. 

 391.	[clarity]	ISC_R_FAMILY -> ISC_R_FAMILYMISMATCH.

36 37 38 39 40
 390.	[func]		The function dns_zone_setdbtype() now takes
			an argc/argv style vector of words and sets 
			both the zone database type and its arguments,
			making the functions dns_zone_adddbarg()
			and dns_zone_cleardbargs() unnecessary.

 377.	[bug]		When additional data lookups were refused due to 
78 79 80
			"allow-query", the databases were still being
			attached causing reference leaks.

81 82 83
 376.	[bug]		The server should always use good entropy when
			performing cryptographic functions needing entropy.

84 85 86 87 88 89
 375.	[bug]		Per-zone "allow-query" did not properly override the
			view/global one for CNAME targets and additional
			data [RT #220].

 374.	[bug]		SOA in authoritative negative responses had wrong TTL.

90 91
 373.	[func]		nslookup is now installed by "make install".

 362.	[bug]		rndc no longer aborts if the configuration file is
			missing an options statement. [RT #209]

123 124 125 126 127 128 129 130 131 132
 361.	[func]		When the RBT find or chain functions set the name and
			origin for a node that stores the root label
			the name is now set to an empty name, instead of ".",
			to simplify later use of the name and origin by
			dns_name_concatenate(), dns_name_totext() or
			dns_name_format().

 360.	[func]		dns_name_totext() and dns_name_format() now allow
			an empty name to be passed, which is formatted as "@".

133 134
 359.	[bug]		dnssec-signzone occasionally signed glue records.

			an assertion failure.

155 156 157
 351.	[bug]		Constructing a response with rcode SERVFAIL to a TSIG
			signed query could crash the server.

158 159 160 161

			a memory leak.

162
 349.	[bug]		Processing a query with the CD bit set now works
163 164
			as expected.

165 166 167 168

			* Significantly improve structure handling
			* Don't pre-load entire batch files
			* Add name/rr counting/limiting
			* Fix SIGINT handling
			* Shorten timeouts to match v8's behavior
181 182

 344.	[bug]		When shutting down, lwresd sometimes tried
183
			to shut down its client tasks twice,
184 185
			triggering an assertion.

186 187 188 189 190 191 192 193 194
 343.	[bug]		Although zone maintenance SOA queries and
			notify requests were signed with TSIG keys
			when configured for the server in case,
			the TSIG was not verified on the response.

 342.	[bug]		The wrong name was being passed to
			dns_name_dup() when generating a TSIG
			key using TKEY.

195
 341.	[func]		Support 'key' clause in named.conf zone masters
196 197
			statement:

198

206 207 208 209
 339.	[bug]		DNSSEC validation of the response to an ANY
			query at a name with a CNAME RR in a secure
			zone triggered an assertion failure.

210 211
 338.	[bug]		lwresd logged to syslog as named, not lwresd.

212 213 214
 337.	[bug]		"dig" did not recognize "nsap-ptr" as an RR type
			on the command line.

215 216 217 218
 336.	[bug]		"dig -f" used 64 k of memory for each line in
			the file.  It now uses much less, though still
			proportionally to the file size.

219 220 221
 335.	[bug]		named would occasionally attempt recursion when
			it was disallowed or undesired.

222 223
 334.	[func]		Added hmac-md5 to libisc.

224
 333.	[bug]		The resolver incorrectly accepted referrals to
225 226
			domains that were not parents of the query name,
			causing assertion failures.
227

228 229
 332.	[func]		New function dns_name_reset().

230 231
 331.	[bug]		Only log "recursion denied" if RD is set. (RT #178)

232 233
 330.	[func]		New function isc_log_wouldlog().

234 235 236 237
 329.	[func]		omapi_auth_register() now takes a size_t argument for
			the length of a key's secret data.  Previously
			OMAPI only stored secrets up to the first NUL byte.

238 239
 328.	[func]		Added isc_base64_decodestring().

240 241 242
 327.	[bug]		rndc.conf parser wasn't correctly recognising an IP
			address where a host specification was required.

243 244
 326.	[func]		'keys' in an 'inet' control statement is now
			required and must have at least one item in it.
245 246
			A "not supported" warning is now issued if a 'unix'
			control channel is defined.
247

248 249
 325.	[bug]		isc_lex_gettoken was processing octal strings when
			ISC_LEXOPT_CNUMBER was not set.

251 252 253 254
 324.	[func]		In the resolver, turn EDNS0 off if there is no
			response after a number of retransmissions.
			This is to allow queries some chance of succeeding
			even if all the authoritative servers of a zone
255
			silently discard EDNS0 requests instead of
256 257
			sending an error response like they ought to.

258
 323.	[bug]		dns_rbt_findname() did not ignore empty rbt nodes.
259
			Because of this, servers authoritative for a parent
260 261 262 263
			and grandchild zone but not authoritative for the
			intervening child zone did not correctly issue
			referrals to the servers of the child zone.

266 267 268
			DNSSEC insecurity proofs work in many cases
			where they previously didn't.

269 270 271 272 273
 321.	[bug]		When synthesizing a CNAME RR for a DNAME
			response, query_addcname() failed to intitialize
			the type and class of the CNAME dns_rdata_t,
			causing random failures.

274 275 276 277 278
 320.	[func]		Multiple rndc changes: parses an rndc.conf file,
			uses authentication to talk to named, command
			line syntax changed.  This will all be described
			in the ARM.

279 280 281
 319.	[func]		The named.conf "controls" statement is now used
			to configure the OMAPI command channel.

282 283 284
 318.	[func]		dns_c_ndcctx_destroy() could never return anything
			except ISC_R_SUCCESS; made it have void return instead.

285 286 287 288
 317.	[func]		Use callbacks from libomapi to determine if a
			new connection is valid, and if a key requested
			to be used with that connection is valid.

289 290
 316.	[bug]		Generate a warning if we detect an unexpected <eof>
			but treat as <eol><eof>.

294
 314.	[func]		The named.conf controls statement can now have
295
			more than one key specified for the inet clause.
296

297
 313.	[bug]		When parsing resolv.conf, don't terminate on an
298
			error.	Instead, parse as much as possible, but
299 300
			still return an error if one was found.

301 302 303 304 305
 312.	[bug]		Increase the number of allowed elements in the
			resolv.conf search path from 6 to 8.  If there
			are more than this, ignore the remainder rather
			than returning a failure in lwres_conf_parse.

306 307 308
 311.	[bug]		lwres_conf_parse failed when the first line of
			resolv.conf was empty or a comment.

309 310 311 312 313 314 315 316 317 318 319 320 321
 310.	[func]		Changes to named.conf "controls" statement (inet
			subtype only)

			  - support "keys" clause

				controls {
				   inet * port 1024
					allow { any; } keys { "foo"; }
				}

			  - allow "port xxx" to be left out of statement,
			    in which case it defaults to omapi's default port
			    of 953.
322

323 324 325 326 327 328
 309.	[bug]		When sending a referral, the server did not look
			for name server addresses as glue in the zone
			holding the NS RRset in the case where this zone
			was not the same as the one where it looked for
			name server addresses as authoritative data.

329 330 331
 308.	[bug]		Treat a SOA record not at top of zone as an error
			when loading a zone. (RT #154)

332 333 334 335 336 337
 307.	[bug]		When canceling a query, the resolver didn't check for
			isc_socket_sendto() calls that did not yet have their
			completion events posted, so it could (rarely) end up
			destroying the query context and then want to use
			it again when the send event posted, triggering an
			assertion as it tried to cancel an already-canceled
338
			query.	(RT #77)
339

340
 306.	[bug]		Reading HMAC-MD5 private key files didn't work.

			an address database.

349 350 351 352
 304.	[bug]		If more than LWRES_CONFMAXNAMESERVERS servers
			are listed in resolv.conf, silently ignore them
			instead of returning failure.

361

362 363 364 365 366 367
 300.	[bug]		Using both <isc/net.h> and <lwres/net.h> didn't work
			on platforms lacking IPv6 because each included their
			own ipv6 header file for the missing definitions.  Now
			each library's ipv6.h defines the wrapper symbol of
			the other (ISC_IPV6_H and LWRES_IPV6_H).

368 369 370
 299.	[cleanup]	Get the user and group information before changing the
			root directory, so the administrator does not need to
			keep a copy of the user and group databases in the
371
			chroot'ed environment.	Suggested by Hakan Olsson.
372

373 374 375 376
 298.	[bug]		A mutex deadlock occurred during shutdown of the
			interface manager under certain conditions.
			Digital Unix systems were the most affected.

377 378
 297.	[bug]		Specifying a key name that wasn't fully qualified
			in certain parts of the config file could cause
379
			an assertion failure.
380

381 382 383 384

			failed unless configure had been run in the source
			directory, too.

385 386 387 388 389 390 391 392
 295.	[bug]		When invoked with type==CNAME and a message
			not constructed by dns_message_parse(),
			dns_message_findname() failed to find anything
			due to checking for attribute bits that are set
			only in dns_message_parse().   This caused an
			infinite loop when constructing the response to
			an ANY query at a CNAME in a secure zone.

399

400 401 402 403 404 405 406
 292.	[bug]		Due to problems with the way some operating systems
			handle simultaneous listening on IPv4 and IPv6
			addresses, the server no longer listens on IPv6
			addresses by default.  To revert to the previous
			behavior, specify "listen-on-v6 { any; };" in
			the config file.

407 408 409 410

430 431
 285.	[bug]		A change made to the dst API for beta4 inadvertently
