Acknowledgments - -Introduction - -BIND (Berkeley Internet Name Domain) is a complete, highly portable -implementation of the DNS (Domain Name System) protocol. - -The BIND name server, named, is able to serve as an authoritative name -server, recursive resolver, DNS forwarder, or all three simultaneously. It -implements views for split-horizon DNS, automatic DNSSEC zone signing and -key management, catalog zones to facilitate provisioning of zone data -throughout a name server constellation, response policy zones (RPZ) to -protect clients from malicious data, response rate limiting (RRL) and -recursive query limits to reduce distributed denial of service attacks, -and many other advanced DNS features. BIND also includes a suite of -administrative tools, including the dig and delv DNS lookup tools, -nsupdate for dynamic DNS zone updates, rndc for remote name server -administration, and more. - -BIND 9 is a complete re-write of the BIND architecture that was used in -versions 4 and 8. Internet Systems Consortium (https://www.isc.org), a 501 -(c)(3) public benefit corporation dedicated to providing software and -services in support of the Internet infrastructure, developed BIND 9 and -is responsible for its ongoing maintenance and improvement. BIND is open -source software licenced under the terms of the ISC License for all -versions up to and including BIND 9.10, and the Mozilla Public License -version 2.0 for all subsequent verisons. - -For a summary of features introduced in past major releases of BIND, see -the file HISTORY. - -For a detailed list of changes made throughout the history of BIND 9, see -the file CHANGES. See below for details on the CHANGES file format. - -For up-to-date release notes and errata, see http://www.isc.org/software/ -bind9/releasenotes - -Reporting bugs and getting help - -To report non-security-sensitive bugs or request new features, you may -open an Issue in the BIND 9 project on the ISC GitLab server at https:// -gitlab.isc.org/isc-projects/bind9. - -Please note that, unless you explicitly mark the newly created Issue as -"confidential", it will be publicly readable. Please do not include any -information in bug reports that you consider to be confidential unless the -issue has been marked as such. In particular, if submitting the contents -of your configuration file in a non-confidential Issue, it is advisable to -obscure key secrets: this can be done automatically by using -named-checkconf -px. - -If the bug you are reporting is a potential security issue, such as an -assertion failure or other crash in named, please do NOT use GitLab to -report it. Instead, please send mail to security-officer@isc.org. - -Professional support and training for BIND are available from ISC at -https://www.isc.org/support. - -To join the BIND Users mailing list, or view the archives, visit https:// -lists.isc.org/mailman/listinfo/bind-users. - -If you're planning on making changes to the BIND 9 source code, you may -also want to join the BIND Workers mailing list, at https://lists.isc.org/ -mailman/listinfo/bind-workers. - -Contributing to BIND - -ISC maintains a public git repository for BIND; details can be found at -http://www.isc.org/git/. - -Information for BIND contributors can be found in the following files: - -General information: doc/dev/contrib.md - BIND 9 code style: doc/dev/ -style.md - BIND architecture and developer guide: doc/dev/dev.md - -Patches for BIND may be submitted as Merge Requests in the ISC GitLab -server at at https://gitlab.isc.org/isc-projects/bind9/merge_requests. - -By default, external contributors don't have ability to fork BIND in the -GitLab server, but if you wish to contribute code to BIND, you may request -permission to do so. Thereafter, you can create git branches and directly -submit requests that they be reviewed and merged. - -If you prefer, you may also submit code by opening a GitLab Issue and -including your patch as an attachment, preferably generated by git -format-patch. - -BIND 9.10 features - -BIND 9.10.0 includes a number of changes from BIND 9.9 and earlier -releases. New features include: - - * DNS Response-rate limiting (DNS RRL), which blunts the impact of - reflection and amplification attacks, is always compiled in and no - longer requires a compile-time option to enable it. - * An experimental "Source Identity Token" (SIT) EDNS option is now - available. Similar to DNS Cookies as invented by Donald Eastlake 3rd, - these are designed to enable clients to detect off-path spoofed - responses, and to enable servers to detect spoofed-source queries. - Servers can be configured to send smaller responses to clients that - have not identified themselves using a SIT option, reducing the - effectiveness of amplification attacks. RRL processing has also been - updated; clients proven to be legitimate via SIT are not subject to - rate limiting. Use configure --enable-sit to enable this feature in - BIND. - * A new zone file format, map, stores zone data in a format that can be - mapped directly into memory, allowing significantly faster zone - loading. - * delv (domain entity lookup and validation) is a new tool with dig-like - semantics for looking up DNS data and performing internal DNSSEC - validation. This allows easy validation in environments where the - resolver may not be trustworthy, and assists with troubleshooting of - DNSSEC problems. (NOTE: In previous development releases of BIND 9.10, - this utility was called delve. The spelling has been changed to avoid - confusion with the delve utility included with the Xapian search - engine.) - * Improved EDNS(0) processing for better resolver performance and - reliability over slow or lossy connections. - * A new configure --with-tuning=large option tunes certain compiled-in - constants and default settings to values better suited to large - servers with abundant memory. This can improve performance on such - servers, but will consume more memory and may degrade performance on - smaller systems. - * Substantial improvement in response-policy zone (RPZ) performance. Up - to 32 response-policy zones can be configured with minimal performance - loss. - * To improve recursive resolver performance, cache records which are - still being requested by clients can now be automatically refreshed - from the authoritative server before they expire, reducing or - eliminating the time window in which no answer is available in the - cache. - * New rpz-client-ip triggers and drop policies allowing response - policies based on the IP address of the client. - * ACLs can now be specified based on geographic location using the - MaxMind GeoIP databases. Use configure --with-geoip to enable. - * Zone data can now be shared between views, allowing multiple views to - serve the same zones authoritatively without storing multiple copies - in memory. - * New XML schema (version 3) for the statistics channel includes many - new statistics and uses a flattened XML tree for faster parsing. The - older schema is now deprecated. - * A new stylesheet, based on the Google Charts API, displays XML - statistics in charts and graphs on javascript-enabled browsers. - * The statistics channel can now provide data in JSON format as well as - XML. - * New stats counters track TCP and UDP queries received per zone, and - EDNS options received in total. - * The internal and export versions of the BIND libraries (libisc, - libdns, etc) have been unified so that external library clients can - use the same libraries as BIND itself. - * A new compile-time option, configure --enable-native-pkcs11, allows - BIND 9 cryptography functions to use the PKCS#11 API natively, so that - BIND can drive a cryptographic hardware service module (HSM) directly - instead of using a modified OpenSSL as an intermediary. (Note: This - feature requires an HSM to have a full implementation of the PKCS#11 - API; many current HSMs only have partial implementations. The new - pkcs11-tokens command can be used to check API completeness. Native - PKCS#11 is known to work with the Thales nShield HSM and with SoftHSM - version 2 from the Open DNSSEC project.) - * The new max-zone-ttl option enforces maximum TTLs for zones. This can - simplify the process of rolling DNSSEC keys by guaranteeing that - cached signatures will have expired within the specified amount of - time. - * dig +subnet sends an EDNS CLIENT-SUBNET option when querying. - * dig +expire sends an EDNS EXPIRE option when querying. When this - option is sent with an SOA query to a server that supports it, it will - report the expiry time of a slave zone. - * New dnssec-coverage tool to check DNSSEC key coverage for a zone and - report if a lapse in signing coverage has been inadvertently - scheduled. - * Signing algorithm flexibility and other improvements for the rndc - control channel. - * named-checkzone and named-compilezone can now read journal files, - allowing them to process dynamic zones. - * Multiple DLZ databases can now be configured. Individual zones can be - configured to be served from a specific DLZ database. DLZ databases - now serve zones of type master and redirect. - * rndc zonestatus reports information about a specified zone. - * named now listens on IPv6 as well as IPv4 interfaces by default. - * named now preserves the capitalization of names when responding to - queries: for instance, a query for "example.com" may be answered with - "example.COM" if the name was configured that way in the zone file. - Some clients have a bug causing them to depend on the older behavior, - in which the case of the answer always matched the case of the query, - rather than the case of the name configured in the DNS. Such clients - can now be specified in the new no-case-compress ACL; this will - restore the older behavior of named for those clients only. - * new dnssec-importkey command allows the use of offline DNSSEC keys - with automatic DNSKEY management. - * New named-rrchecker tool to verify the syntactic correctness of - individual resource records. - * When re-signing a zone, the new dnssec-signzone -Q option drops - signatures from keys that are still published but are no longer - active. - * named-checkconf -px will print the contents of configuration files - with the shared secrets obscured, making it easier to share - configuration (e.g. when submitting a bug report) without revealing - private information. - * rndc scan causes named to re-scan network interfaces for changes in - local addresses. - * On operating systems with support for routing sockets, network - interfaces are re-scanned automatically whenever they change. - * tsig-keygen is now available as an alternate command name to use for - ddns-confgen. - -BIND 9.10.1 - -BIND 9.10.1 is a maintenance release, and addresses the security flaws -described in CVE-2014-3214 and CVE-2014-3859. - -BIND 9.10.2 - -BIND 9.10.2 is a maintenance release, and addresses the security flaws -described in CVE-2014-8500, CVE-2014-8680 and CVE-2015-1349. - -BIND 9.10.3 - -BIND 9.10.3 is a maintenance release, and addresses the security flaws -described in CVE-2015-4620, CVE-2015-5477, CVE-2015-5722, and -CVE-2015-5986. - -It also makes the following new features available: - - * New "fetchlimit" quotas are now available for the use of recursive - resolvers that are are under high query load for domains whose - authoritative servers are nonresponsive or are experiencing a denial - of service attack. - - + fetches-per-server limits the number of simultaneous queries that - can be sent to any single authoritative server. The configured - value is a starting point; it is automatically adjusted downward - if the server is partially or completely non-responsive. The - algorithm used to adjust the quota can be configured via the - fetch-quota-params option. - + fetches-per-zone limits the number of simultaneous queries that - can be sent for names within a single domain. (Note: Unlike - fetches-per-server, this value is not self-tuning.) - + New stats counters have been added to count queries spilled due to - these quotas. - -NOTE: These features are NOT built in by default; use configure ---enable-fetchlimit to enable them. - - * dig now supports sending of arbitrary EDNS options by specifying them - on the command line. - -BIND 9.10.4 - -BIND 9.10.4 is a maintenance release, and addresses the security flaws -described in CVE-2015-8000, CVE-2015-8461, CVE-2015-8704, CVE-2015-8705, -CVE-2016-1285, CVE-2016-1286, CVE-2016-2088, CVE-2016-2775 and -CVE-2016-2776. - -BIND 9.10.5 - -BIND 9.10.5 is a maintenance release, and addresses the security flaws -disclosed in CVE-2016-2775, CVE-2016-2776, CVE-2016-6170, CVE-2016-8864, -CVE-2016-9131, CVE-2016-9147, CVE-2016-9444, CVE-2017-3135, CVE-2017-3136, -CVE-2017-3137, and CVE-2017-3138. - -BIND 9.10.6 - -BIND 9.10.6 is a maintenance release, and addresses the security flaws -disclosed in CVE-2017-3140 and CVE-2017-3141, CVE-2017-3142 and -CVE-2017-3143. - -BIND 9.10.7 - -BIND 9.10.7 is a maintenance release, and addresses the security flaw -disclosed in CVE-2017-3145. - -BIND 9.10.8 - -BIND 9.10.8 is a maintenance release, and addresses the security flaw -disclosed in CVE-2018-5738. - -Building BIND - -BIND requires a UNIX or Linux system with an ANSI C compiler, basic POSIX -support, and a 64-bit integer type. Successful builds have been observed -on many versions of Linux and UNIX, including RedHat, Fedora, Debian, -Ubuntu, SuSE, Slackware, FreeBSD, NetBSD, OpenBSD, Mac OS X, Solaris, -HP-UX, AIX, SCO OpenServer, and OpenWRT. - -BIND is also available for Windows XP, 2003, 2008, and higher. See -win32utils/readme1st.txt for details on building for Windows systems. - -To build on a UNIX or Linux system, use: - - $ ./configure - $ make - -If you're planning on making changes to the BIND 9 source, you should run -make depend. If you're using Emacs, you might find make tags helpful. - -Several environment variables that can be set before running configure -will affect compilation: - -Variable Description -CC The C compiler to use. configure tries to figure out the - right one for supported systems. - C compiler flags. Defaults to include -g and/or -O2 as -CFLAGS supported by the compiler. Please include '-g' if you need - to set CFLAGS. - System header file directories. Can be used to specify -STD_CINCLUDES where add-on thread or IPv6 support is, for example. - Defaults to empty string. - Any additional preprocessor symbols you want defined. -STD_CDEFINES Defaults to empty string. For a list of possible settings, - see the file OPTIONS. -LDFLAGS Linker flags. Defaults to empty string. -BUILD_CC Needed when cross-compiling: the native C compiler to use - when building for the target system. -BUILD_CFLAGS Optional, used for cross-compiling -BUILD_CPPFLAGS -BUILD_LDFLAGS -BUILD_LIBS - -macOS - -Building on macOS assumes that the "Command Tools for Xcode" is installed. -This can be downloaded from https://developer.apple.com/download/more/ or -if you have Xcode already installed you can run "xcode-select --install". -This will add /usr/include to the system and install the compiler and -other tools so that they can be easily found. - -Compile-time options - -To see a full list of configuration options, run configure --help. - -On most platforms, BIND 9 is built with multithreading support, allowing -it to take advantage of multiple CPUs. You can configure this by -specifying --enable-threads or --disable-threads on the configure command -line. The default is to enable threads, except on some older operating -systems on which threads are known to have had problems in the past. -(Note: Prior to BIND 9.10, the default was to disable threads on Linux -systems; this has now been reversed. On Linux systems, the threaded build -is known to change BIND's behavior with respect to file permissions; it -may be necessary to specify a user with the -u option when running named.) - -To build shared libraries, specify --with-libtool on the configure command -line. - -Certain compiled-in constants and default settings can be increased to -values better suited to large servers with abundant memory resources (e.g, -64-bit servers with 12G or more of memory) by specifying --with-tuning= -large on the configure command line. This can improve performance on big -servers, but will consume more memory and may degrade performance on -smaller systems. - -For the server to support DNSSEC, you need to build it with crypto -support. To use OpenSSL, you should have OpenSSL 1.0.2e or newer -installed. If the OpenSSL library is installed in a nonstandard location, -specify the prefix using "--with-openssl=<PREFIX>" on the configure -command line. To use a PKCS#11 hardware service module for cryptographic -operations, specify the path to the PKCS#11 provider library using -"--with-pkcs11=<PREFIX>", and configure BIND with -"--enable-native-pkcs11". - -To support the HTTP statistics channel, the server must be linked with at -least one of the following: libxml2 http://xmlsoft.org or json-c https:// -github.com/json-c. If these are installed at a nonstandard location, -specify the prefix using --with-libxml2=/prefix or --with-libjson=/prefix. - -To support GeoIP location-based ACLs, the server must be linked with -libGeoIP. This is not turned on by default; BIND must be configured with -"--with-geoip". If the library is installed in a nonstandard location, use -specify the prefix using "--with-geoip=/prefix". - -Portions of BIND that are written in Python, including dnssec-coverage, -dnssec-checkds, and some of the system tests, require the 'argparse' -module to be available. 'argparse' is a standard module as of Python 2.7 -and Python 3.2. - -On some platforms it is necessary to explicitly request large file support -to handle files bigger than 2GB. This can be done by using ---enable-largefile on the configure command line. - -Support for the "fixed" rrset-order option can be enabled or disabled by -specifying --enable-fixed-rrset or --disable-fixed-rrset on the configure -command line. By default, fixed rrset-order is disabled to reduce memory -footprint. - -If your operating system has integrated support for IPv6, it will be used -automatically. If you have installed KAME IPv6 separately, use --with-kame -[=PATH] to specify its location. - -make install will install named and the various BIND 9 libraries. By -default, installation is into /usr/local, but this can be changed with the ---prefix option when running configure. - -You may specify the option --sysconfdir to set the directory where -configuration files like named.conf go by default, and --localstatedir to -set the default parent directory of run/named.pid. For backwards -compatibility with BIND 8, --sysconfdir defaults to /etc and ---localstatedir defaults to /var if no --prefix option is given. If there -is a --prefix option, sysconfdir defaults to $prefix/etc and localstatedir -defaults to $prefix/var. - -Automated testing - -A system test suite can be run with make test. The system tests require -you to configure a set of virtual IP addresses on your system (this allows -multiple servers to run locally and communicate with one another). These -IP addresses can be configured by running the command bin/tests/system/ -ifconfig.sh up as root. - -Some tests require Perl and the Net::DNS and/or IO::Socket::INET6 modules, -and will be skipped if these are not available. Some tests require Python -and the 'dnspython' module and will be skipped if these are not available. -See bin/tests/system/README for further details. - -Unit tests are implemented using Automated Testing Framework (ATF). To run -them, use configure --with-atf, then run make test or make unit. - -Documentation - -The BIND 9 Administrator Reference Manual is included with the source -distribution, in DocBook XML, HTML and PDF format, in the doc/arm -directory. - -Some of the programs in the BIND 9 distribution have man pages in their -directories. In particular, the command line options of named are -documented in bin/named/named.8. - -Frequently (and not-so-frequently) asked questions and their answers can -be found in the ISC Knowledge Base at https://kb.isc.org. - -Additional information on various subjects can be found in other README -files throughout the source tree. - -Change log - -A detailed list of all changes that have been made throughout the -development BIND 9 is included in the file CHANGES, with the most recent -changes listed first. Change notes include tags indicating the category of -the change that was made; these categories are: - -Category Description -[func] New feature -[bug] General bug fix -[security] Fix for a significant security flaw -[experimental] Used for new features when the syntax or other aspects of - the design are still in flux and may change -[port] Portability enhancement -[maint] Updates to built-in data such as root server addresses and - keys -[tuning] Changes to built-in configuration defaults and constants to - improve performance -[performance] Other changes to improve server performance -[protocol] Updates to the DNS protocol such as new RR types -[test] Changes to the automatic tests, not affecting server - functionality -[cleanup] Minor corrections and refactoring -[doc] Documentation -[contrib] Changes to the contributed tools and libraries in the - 'contrib' subdirectory - Used in the master development branch to reserve change -[placeholder] numbers for use in other branches, e.g. when fixing a bug - that only exists in older releases - -In general, [func] and [experimental] tags will only appear in new-feature -releases (i.e., those with version numbers ending in zero). Some new -functionality may be backported to older releases on a case-by-case basis. -All other change types may be applied to all currently-supported releases. - -Acknowledgments - - * The original development of BIND 9 was underwritten by the following - organizations: - - Sun Microsystems, Inc. - Hewlett Packard - Compaq Computer Corporation - IBM - Process Software Corporation - Silicon Graphics, Inc. - Network Associates, Inc. - U.S. Defense Information Systems Agency - USENIX Association - Stichting NLnet - NLnet Foundation - Nominum, Inc. - - * This product includes software developed by the OpenSSL Project for - use in the OpenSSL Toolkit. http://www.OpenSSL.org/ - * This product includes cryptographic software written by Eric Young - (eay@cryptsoft.com) - * This product includes software written by Tim Hudson - (tjh@cryptsoft.com) |
