			"allow-query", the databases were still being
			attached causing reference leaks.

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

24

 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 "@".

67
68

115
116

 344.	[bug]		When shutting down, lwresd sometimes tried
117
			to shut down its client tasks twice,
118
119
			triggering an assertion.

120
121
122
123
124
125

 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.

129
 341.	[func]		Support 'key' clause in named.conf zone masters
130
131
			statement:

132
				masters {
133
134
135
					10.0.0.1 port 666 key "foo";

 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.

144
145
 338.	[bug]		lwresd logged to syslog as named, not lwresd.

146
147
148
 337.	[bug]		"dig" did not recognize "nsap-ptr" as an RR type
			on the command line.

149
150
151
152
 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.

153
154
155
 335.	[bug]		named would occasionally attempt recursion when
			it was disallowed or undesired.

156
157
 334.	[func]		Added hmac-md5 to libisc.

158
 333.	[bug]		The resolver incorrectly accepted referrals to
159
160
			domains that were not parents of the query name,
			causing assertion failures.
161

162
163
 332.	[func]		New function dns_name_reset().

164
165
 331.	[bug]		Only log "recursion denied" if RD is set. (RT #178)

166
167
 330.	[func]		New function isc_log_wouldlog().

168
169
170
171
 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.

172
173
 328.	[func]		Added isc_base64_decodestring().

174
175
176
 327.	[bug]		rndc.conf parser wasn't correctly recognising an IP
			address where a host specification was required.

177
178
 326.	[func]		'keys' in an 'inet' control statement is now
			required and must have at least one item in it.
179
180
			A "not supported" warning is now issued if a 'unix'
			control channel is defined.
181

182
183
 325.	[bug]		isc_lex_gettoken was processing octal strings when
			ISC_LEXOPT_CNUMBER was not set.

185
186
187
188
 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
189
			silently discard EDNS0 requests instead of
190
191
			sending an error response like they ought to.

192
 323.	[bug]		dns_rbt_findname() did not ignore empty rbt nodes.
193
			Because of this, servers authoritative for a parent
194
195
196
197
			and grandchild zone but not authoritative for the
			intervening child zone did not correctly issue
			referrals to the servers of the child zone.

			DNSSEC insecurity proofs work in many cases

203
204
205
206
207
 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.

208
209
210
211
212
 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.

213
214
215
 319.	[func]		The named.conf "controls" statement is now used
			to configure the OMAPI command channel.

216
217
218
 318.	[func]		dns_c_ndcctx_destroy() could never return anything
			except ISC_R_SUCCESS; made it have void return instead.

219
220
221
222
 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.

223
224
 316.	[bug]		Generate a warning if we detect an unexpected <eof>
			but treat as <eol><eof>.

 315.	[bug]		Handle non-empty blanks lines. (RT #163)
227

228
 314.	[func]		The named.conf controls statement can now have
229
			more than one key specified for the inet clause.
230

231
 313.	[bug]		When parsing resolv.conf, don't terminate on an
232
			error.	Instead, parse as much as possible, but
233
234
			still return an error if one was found.

235
236
237
238
239
 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.

240
241
242
 311.	[bug]		lwres_conf_parse failed when the first line of
			resolv.conf was empty or a comment.

 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.
256

257
258
259
260
261
262
 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.

263
264
265
 308.	[bug]		Treat a SOA record not at top of zone as an error
			when loading a zone. (RT #154)

266
267
268
269
270
271
 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
272
			query.	(RT #77)
273

274
 306.	[bug]		Reading HMAC-MD5 private key files didn't work.

			are listed in resolv.conf, silently ignore them
			instead of returning failure.

287

288

300
301
 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).

302
303
304
 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
305
			chroot'ed environment.	Suggested by Hakan Olsson.

			interface manager under certain conditions.
			Digital Unix systems were the most affected.

311

 297.	[bug]		Specifying a key name that wasn't fully qualified
			in certain parts of the config file could cause
313
			an assertion failure.

325
326
 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.

 294.	[bug]		If we run out of space in while processing glue
			when reading a master file and commit "current name"
			reverts to "name_current" instead of staying as
			"name_glue".

332
 293.	[port]		Add support for FreeBSD 4.0 system tests.
333

334
335
336
337
338
339
340
 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.

341

364
365

				isc_buffer_consumedlength(b)	(int)
				isc_buffer_remaininglength(b)	(int)
				isc_buffer_activelength(b)	(int)
