 392.	[func]		Add ISC_R_FAMILYNOSUPPORT.  Returned when OS does
			not support the given address family requested.

 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 
48 49 50
			"allow-query", the databases were still being

54 55 56 57 58 59

93 94 95 96 97 98 99 100 101 102
 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

125 126 127
 351.	[bug]		Constructing a response with rcode SERVFAIL to a TSIG

128 129 130 131

133 134

			* Add name/rr counting/limiting
			* Fix SIGINT handling
			* Shorten timeouts to match v8's behavior
151 152

 344.	[bug]		When shutting down, lwresd sometimes tried
153
			to shut down its client tasks twice,
154 155
			triggering an assertion.

156 157 158 159 160 161 162 163 164
 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.

165
 341.	[func]		Support 'key' clause in named.conf zone masters
166 167
			statement:

168

176 177 178 179
 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.

180 181
 338.	[bug]		lwresd logged to syslog as named, not lwresd.

182 183 184
 337.	[bug]		"dig" did not recognize "nsap-ptr" as an RR type
			on the command line.

185 186 187 188
 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.

189 190 191
 335.	[bug]		named would occasionally attempt recursion when
			it was disallowed or undesired.

192 193
 334.	[func]		Added hmac-md5 to libisc.

194
 333.	[bug]		The resolver incorrectly accepted referrals to
195 196
			domains that were not parents of the query name,
			causing assertion failures.
197

198 199
 332.	[func]		New function dns_name_reset().

200 201
 331.	[bug]		Only log "recursion denied" if RD is set. (RT #178)

202 203
 330.	[func]		New function isc_log_wouldlog().

204 205 206 207
 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.

208 209
 328.	[func]		Added isc_base64_decodestring().

210 211 212
 327.	[bug]		rndc.conf parser wasn't correctly recognising an IP
			address where a host specification was required.

213 214
 326.	[func]		'keys' in an 'inet' control statement is now
			required and must have at least one item in it.
215 216
			A "not supported" warning is now issued if a 'unix'
			control channel is defined.
217

218 219

			ISC_LEXOPT_CNUMBER was not set.

221 222 223 224
 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
225
			silently discard EDNS0 requests instead of
226 227
			sending an error response like they ought to.

228
 323.	[bug]		dns_rbt_findname() did not ignore empty rbt nodes.
229
			Because of this, servers authoritative for a parent
230 231 232 233
			and grandchild zone but not authoritative for the
			intervening child zone did not correctly issue
			referrals to the servers of the child zone.

236 237 238
			DNSSEC insecurity proofs work in many cases
			where they previously didn't.

239 240 241 242 243
 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.

244 245 246 247 248
 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.

249 250 251
 319.	[func]		The named.conf "controls" statement is now used
			to configure the OMAPI command channel.

252 253 254
 318.	[func]		dns_c_ndcctx_destroy() could never return anything
			except ISC_R_SUCCESS; made it have void return instead.

255 256 257 258
 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.

259 260
 316.	[bug]		Generate a warning if we detect an unexpected <eof>
			but treat as <eol><eof>.

264
 314.	[func]		The named.conf controls statement can now have
265
			more than one key specified for the inet clause.
266

267
 313.	[bug]		When parsing resolv.conf, don't terminate on an
268
			error.	Instead, parse as much as possible, but
269 270
			still return an error if one was found.

271 272 273 274 275
 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.

276 277 278
 311.	[bug]		lwres_conf_parse failed when the first line of
			resolv.conf was empty or a comment.

279 280 281 282 283 284 285 286 287 288 289 290 291
 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.
292

293 294 295 296 297 298
 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.

299 300 301
 308.	[bug]		Treat a SOA record not at top of zone as an error
			when loading a zone. (RT #154)

302 303 304 305 306 307
 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
308
			query.	(RT #77)
309

310
 306.	[bug]		Reading HMAC-MD5 private key files didn't work.

			assertion failure trying to perform zone
			maintenance on tentatively created zones whose
			views were never fully configured and lacked
			an address database.

319 320 321 322
 304.	[bug]		If more than LWRES_CONFMAXNAMESERVERS servers
			are listed in resolv.conf, silently ignore them
			instead of returning failure.

323
 303.	[bug]		Add additional sanity checks to differentiate a AXFR
324 325

331

332 333 334 335 336 337
 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).

338 339 340
 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
341
			chroot'ed environment.	Suggested by Hakan Olsson.
342

343 344 345 346
 298.	[bug]		A mutex deadlock occurred during shutdown of the
			interface manager under certain conditions.
			Digital Unix systems were the most affected.

347 348
 297.	[bug]		Specifying a key name that wasn't fully qualified
			in certain parts of the config file could cause
349
			an assertion failure.

351 352 353 354

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

355 356 357 358 359 360 361 362
 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.

369

370 371 372 373 374 375 376
 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.

377 378 379 380
