53 BIND 9.8.0 includes a number of changes from BIND 9.7 and earlier
54 releases. New features include:
56 - Built-in trust anchor for the root zone, which can be
57 switched on via "dnssec-validation auto;"
59 - Support for response policy zones (RPZ).
60 - Support for writable DLZ zones.
61 - Improved ease of configuration of GSS/TSIG for
62 interoperability with Active Directory
63 - Support for GOST signing algorithm for DNSSEC.
64 - Removed RTT Banding from server selection algorithm.
65 - New "static-stub" zone type.
66 - Allow configuration of resolver timeouts via
67 "resolver-query-timeout" option.
71 BIND 9.7.0 includes a number of changes from BIND 9.6 and earlier
72 releases. Most are intended to simplify DNSSEC configuration.
76 - Fully automatic signing of zones by "named".
77 - Simplified configuration of DNSSEC Lookaside Validation (DLV).
78 - Simplified configuration of Dynamic DNS, using the "ddns-confgen"
79 command line tool or the "local" update-policy option. (As a side
80 effect, this also makes it easier to configure automatic zone
82 - New named option "attach-cache" that allows multiple views to
84 - DNS rebinding attack prevention.
85 - New default values for dnssec-keygen parameters.
86 - Support for RFC 5011 automated trust anchor maintenance
87 - Smart signing: simplified tools for zone signing and key
89 - The "statistics-channels" option is now available on Windows.
90 - A new DNSSEC-aware libdns API for use by non-BIND9 applications
91 - On some platforms, named and other binaries can now print out
92 a stack backtrace on assertion failure, to aid in debugging.
93 - A "tools only" installation mode on Windows, which only installs
94 dig, host, nslookup and nsupdate.
95 - Improved PKCS#11 support, including Keyper support and explicit
96 OpenSSL engine selection.
98 Known issues in this release:
100 - In rare cases, DNSSEC validation can leak memory. When this
101 happens, it will cause an assertion failure when named exits,
102 but is otherwise harmless. A fix exists, but was too late for
103 this release; it will be included in BIND 9.7.1.
107 - If you had built BIND 9.6 with any of ALLOW_NSEC3PARAM_UPDATE,
108 ALLOW_SECURE_TO_INSECURE or ALLOW_INSECURE_TO_SECURE defined, then
109 you should ensure that all changes that are in progress have
110 completed prior to upgrading to BIND 9.7. BIND 9.7 implements
111 those features in a way which is not backwards compatible.
113 - Prior releases had a bug which caused HMAC-SHA* keys with long
114 secrets to be used incorrectly. Fixing this bug means that older
115 versions of BIND 9 may fail to interoperate with this version
116 when using TSIG keys. If this occurs, the new "isc-hmac-fixup"
117 tool will convert a key with a long secret into a form that works
118 correctly with all versions of BIND 9. See the "isc-hmac-fixup"
119 man page for additional details.
121 - Revoking a DNSSEC key with "dnssec-revoke" changes its key ID.
122 It is possible for the new key ID to collide with that of a
123 different key. Newly generated keys will not have this problem,
124 as "dnssec-keygen" looks for potential collisions before
125 generating keys, but exercise caution if using key revokation
126 with keys that were generated by older versions of BIND 9. See
127 the Administrator's Reference Manual, section 4.10 ("Dynamic
128 Trust Anchor Management") for more details.
130 - A bug was fixed in which a key's scheduled inactivity date was
131 stored incorectly. Users who participated in the 9.7.0 BETA test
132 and had DNSSEC keys with scheduled inactivity dates will need to
133 reset those keys' dates using "dnssec-settime -I".
137 BIND 9 currently requires a UNIX system with an ANSI C compiler,
138 basic POSIX support, and a 64 bit integer type.
140 We've had successful builds and tests on the following systems:
142 COMPAQ Tru64 UNIX 5.1B
144 FreeBSD 4.10, 5.2.1, 6.2
147 NetBSD 3.x, 4.0-beta, 5.0-beta
149 Solaris 8, 9, 9 (x86), 10
153 NOTE: As of BIND 9.5.1, 9.4.3, and 9.3.6, older versions of
154 Windows, including Windows NT and Windows 2000, are no longer
157 We have recent reports from the user community that a supported
158 version of BIND will build and run on the following systems:
168 Red Hat Enterprise Linux 4, 5
178 Do not use a parallel "make".
180 Several environment variables that can be set before running
181 configure will affect compilation:
184 The C compiler to use. configure tries to figure
185 out the right one for supported systems.
188 C compiler flags. Defaults to include -g and/or -O2
189 as supported by the compiler.
192 System header file directories. Can be used to specify
193 where add-on thread or IPv6 support is, for example.
194 Defaults to empty string.
197 Any additional preprocessor symbols you want defined.
198 Defaults to empty string.
201 Change the default syslog facility of named/lwresd.
202 -DISC_FACILITY=LOG_LOCAL0
203 Enable DNSSEC signature chasing support in dig.
204 -DDIG_SIGCHASE=1 (sets -DDIG_SIGCHASE_TD=1 and
206 Disable dropping queries from particular well known ports.
207 -DNS_CLIENT_DROPPORT=0
208 Sibling glue checking in named-checkzone is enabled by default.
209 To disable the default check set. -DCHECK_SIBLING=0
210 named-checkzone checks out-of-zone addresses by default.
211 To disable this default set. -DCHECK_LOCAL=0
212 To create the default pid files in ${localstatedir}/run rather
213 than ${localstatedir}/run/{named,lwresd}/ set.
215 Enable workaround for Solaris kernel bug about /dev/poll
216 -DISC_SOCKET_USE_POLLWATCH=1
217 The watch timeout is also configurable, e.g.,
218 -DISC_SOCKET_POLLWATCH_TIMEOUT=20
221 Linker flags. Defaults to empty string.
223 The following need to be set when cross compiling.
226 The native C compiler.
227 BUILD_CFLAGS (optional)
228 BUILD_CPPFLAGS (optional)
230 -DNEED_OPTARG=1 (optarg is not declared in <unistd.h>)
231 BUILD_LDFLAGS (optional)
232 BUILD_LIBS (optional)
234 To build shared libraries, specify "--with-libtool" on the
235 configure command line.
237 For the server to support DNSSEC, you need to build it
238 with crypto support. You must have OpenSSL 0.9.5a
239 or newer installed and specify "--with-openssl" on the
240 configure command line. If OpenSSL is installed under
241 a nonstandard prefix, you can tell configure where to
242 look for it using "--with-openssl=/prefix".
244 On some platforms it is necessary to explictly request large
245 file support to handle files bigger than 2GB. This can be
246 done by "--enable-largefile" on the configure command line.
248 On some platforms, BIND 9 can be built with multithreading
249 support, allowing it to take advantage of multiple CPUs.
250 You can specify whether to build a multithreaded BIND 9
251 by specifying "--enable-threads" or "--disable-threads"
252 on the configure command line. The default is operating
255 Support for the "fixed" rrset-order option can be enabled
256 or disabled by specifying "--enable-fixed-rrset" or
257 "--disable-fixed-rrset" on the configure command line.
258 The default is "disabled", to reduce memory footprint.
260 If your operating system has integrated support for IPv6, it
261 will be used automatically. If you have installed KAME IPv6
262 separately, use "--with-kame[=PATH]" to specify its location.
264 "make install" will install "named" and the various BIND 9 libraries.
265 By default, installation is into /usr/local, but this can be changed
266 with the "--prefix" option when running "configure".
268 You may specify the option "--sysconfdir" to set the directory
269 where configuration files like "named.conf" go by default,
270 and "--localstatedir" to set the default parent directory
271 of "run/named.pid". For backwards compatibility with BIND 8,
272 --sysconfdir defaults to "/etc" and --localstatedir defaults to
273 "/var" if no --prefix option is given. If there is a --prefix
274 option, sysconfdir defaults to "$prefix/etc" and localstatedir
275 defaults to "$prefix/var".
277 To see additional configure options, run "configure --help".
278 Note that the help message does not reflect the BIND 8
279 compatibility defaults for sysconfdir and localstatedir.
281 If you're planning on making changes to the BIND 9 source, you
282 should also "make depend". If you're using Emacs, you might find
285 If you need to re-run configure please run "make distclean" first.
286 This will ensure that all the option changes take.
288 Building with gcc is not supported, unless gcc is the vendor's usual
289 compiler (e.g. the various BSD systems, Linux).
291 Known compiler issues:
292 * gcc-3.2.1 and gcc-3.1.1 is known to cause problems with solaris-x86.
293 * gcc prior to gcc-3.2.3 ultrasparc generates incorrect code at -02.
294 * gcc-3.3.5 powerpc generates incorrect code at -02.
295 * Irix, MipsPRO 7.4.1m is known to cause problems.
297 A limited test suite can be run with "make test". Many of
298 the tests require you to configure a set of virtual IP addresses
299 on your system, and some require Perl; see bin/tests/system/README
302 SunOS 4 requires "printf" to be installed to make the shared
303 libraries. sh-utils-1.16 provides a "printf" which compiles
308 The BIND 9 Administrator Reference Manual is included with the
309 source distribution in DocBook XML and HTML format, in the
312 Some of the programs in the BIND 9 distribution have man pages
313 in their directories. In particular, the command line
314 options of "named" are documented in /bin/named/named.8.
315 There is now also a set of man pages for the lwres library.
317 If you are upgrading from BIND 8, please read the migration
318 notes in doc/misc/migration. If you are upgrading from
319 BIND 4, read doc/misc/migration-4to9.
