 CODE OF CONDUCT
 BIND 9 Code of Conduct
 Like the technical community as a whole, the BIND 9 team and community is
 made up of a mixture of professionals and volunteers from all over the
 world, working on every aspect of the mission - including mentorship,
 teaching, and connecting people.
 Diversity is one of our huge strengths, but it can also lead to
 communication issues and unhappiness. To that end, we have a few ground
 rules that we ask people to adhere to. This code applies equally to the
 core development team, open source contributors and those seeking help and
 guidance.
 This isn't an exhaustive list of things that you can't do. Rather, take it
 in the spirit in which it's intended - a guide to make it easier to enrich
 all of us and the technical communities in which we participate.
 This code of conduct applies to all spaces managed by the BIND 9 project
 or Internet Systems Consortium. This includes chat, the mailing lists, the
 issue tracker, and any other fora created by the project team which the
 community uses for communication. In addition, violations of this code
 outside these spaces may affect a person's ability to participate within
 them.
 If you believe someone is violating the code of conduct, we ask that you
 report it by emailing conduct@isc.org. For more details please see our
 Reporting Guidelines.
  * Be friendly and patient.
  * Be welcoming. We strive to be a community that welcomes and supports
    people of all backgrounds and identities. This includes, but is not
    limited to members of any race, ethnicity, culture, national origin,
    colour, immigration status, social and economic class, educational
    level, sex, sexual orientation, gender identity and expression, age,
    size, family status, political belief, religion, and mental and
    physical ability.
  * Be considerate. Your work will be used by other people, and you in
    turn will depend on the work of others. Any decision you take will
    affect users and colleagues, and you should take those consequences
    into account when making decisions. Remember that we're a world-wide
    community, so you might not be communicating in someone else's primary
    language.
  * Be respectful. Not all of us will agree all the time, but disagreement
    is no excuse for poor behavior and poor manners. We might all
    experience some frustration now and then, but we cannot allow that
    frustration to turn into a personal attack. It's important to remember
    that a community where people feel uncomfortable or threatened is not
    a productive one. Members of the BIND 9 community should be respectful
    when dealing with other members as well as with people outside the
    BIND 9 community.
  * Be careful in the words that you choose. We are a community of
    professionals, and we conduct ourselves professionally. Be kind to
    others. Do not insult or put down other participants. Harassment and
    other exclusionary behavior aren't acceptable. This includes, but is
    not limited to:
      + Violent threats or language directed against another person.
      + Discriminatory jokes and language.
      + Posting sexually explicit or violent material.
      + Posting (or threatening to post) other people's personally
        identifying information ("doxing").
      + Personal insults, especially those using racist or sexist terms.
      + Unwelcome sexual attention.
      + Advocating for, or encouraging, any of the above behavior.
      + Repeated harassment of others. In general, if someone asks you to
        stop, then stop.
  * When we disagree, try to understand why. Disagreements, both social
    and technical, happen all the time and BIND 9 is no exception. It is
    important that we resolve disagreements and differing views
    constructively. Remember that we're different. The strength of BIND 9
    comes from its varied community, people from a wide range of
    backgrounds. Different people have different perspectives on issues.
    Being unable to understand why someone holds a viewpoint doesn't mean
    that they're wrong. Don't forget that it is human to err and blaming
    each other doesn't get us anywhere. Instead, focus on helping to
    resolve issues and learning from mistakes.

 HISTORY
 Functional enhancements from prior major releases of BIND 9
 BIND 9.14
 BIND 9.14 (a stable branch based on the 9.13 development branch) includes
 a number of changes from BIND 9.12 and earlier releases. New features
 include:
  * A new "plugin" mechanism has been added to allow query functionality
    to be extended using dynamically loadable libraries. The "filter-aaaa"
    feature has been removed from named and is now implemented as a
    plugin.
  * Socket and task code has been refactored to improve performance.
  * QNAME minimization, as described in RFC 7816, is now supported.
  * "Root key sentinel" support, enabling validating resolvers to indicate
    via a special query which trust anchors are configured for the root
    zone.
  * Secondary zones can now be configured as "mirror" zones; their
    contents are transferred in as with traditional slave zones, but are
    subject to DNSSEC validation and are not treated as authoritative data
    when answering. This makes it easier to configure a local copy of the
    root zone as described in RFC 7706.
  * The "validate-except" option allows configuration of domains below
    which DNSSEC validation should not be performed.
  * The default value of "dnssec-validation" is now "auto".
  * IDNA2008 is now supported when linking with libidn2.
  * "named -V" now outputs the default paths for files used by named and
    other tools.
 In addition, workarounds that were formerly in place to enable resolution
 of domains whose authoritative servers did not respond to EDNS queries
 have been removed. See https://dnsflagday.net for more details.
 Cryptographic support has been modernized. BIND now uses the best
 available pseudo-random number generator for the platform on which it's
 built. Very old versions of OpenSSL are no longer supported. Cryptography
 is now mandatory: building BIND without DNSSEC is no longer supported.
 Special code to support certain legacy operating systems has also been
 removed; see the file PLATFORMS.md for details of supported platforms. In
 addition to OpenSSL, BIND now requires support for IPv6, threads, and
 standard atomic operations provided by the C compiler.
 BIND 9.12
 BIND 9.12 includes a number of changes from BIND 9.11 and earlier
 releases. New features include:
  * named and related libraries have been substantially refactored for
    improved query performance -- particularly on delegation heavy zones
    -- and for improved readability, maintainability, and testability.
  * Code implementing the name server query processing logic has been
    moved into a new libns library, for easier testing and use in tools
    other than named.
  * Cached, validated NSEC and other records can now be used to synthesize
    NXDOMAIN responses.
  * The DNS Response Policy Service API (DNSRPS) is now supported.
  * Setting 'max-journal-size default' now limits the size of journal
    files to twice the size of the zone.
  * dnstap-read -x prints a hex dump of the wire format of each logged DNS
    message.
  * dnstap output files can now be configured to roll automatically when
    reaching a given size.
  * Log file timestamps can now also be formatted in ISO 8601 (local) or
    ISO 8601 (UTC) formats.
  * Logging channels and dnstap output files can now be configured to use
    a timestamp as the suffix when rolling to a new file.
  * 'named-checkconf -l' lists zones found in named.conf.
  * Added support for the EDNS Padding and Keepalive options.
  * 'new-zones-directory' option sets the location where the configuration
    data for zones added by rndc addzone is stored.
  * The default key algorithm in rndc-confgen is now hmac-sha256.
  * filter-aaaa-on-v4 and filter-aaaa-on-v6 options are now available by
    default without a configure option.

 OPTIONS
 Setting the STD_CDEFINES environment variable before running configure can
 be used to enable certain compile-time options that are not explicitly
 defined in configure.
 Some of these settings are:

 PLATFORMS
 Supported platforms
 In general, this version of BIND will build and run on any POSIX-compliant
 system with a C11-compliant C compiler, BSD-style sockets with
 RFC-compliant IPv6 support, POSIX-compliant threads, the libuv
 asynchronous I/O library, and the OpenSSL cryptography library.
 The following C11 features are used in BIND 9:
  * Atomic operations support from the compiler is needed, either in the
    form of builtin operations, C11 atomics, or the Interlocked family of
    functions on Windows.
  * Thread Local Storage support from the compiler is needed, either in
    the form of C11 _Thread_local/thread_local, the __thread GCC
    extension, or the __declspec(thread) MSVC extension on Windows.
 BIND 9.15 requires a fairly recent version of libuv (at least 1.x). For
 some of the older systems listed below, you will have to install an
 updated libuv package from sources such as EPEL, PPA, or other native
 sources for updated packages. The other option is to build and install
 libuv from source.
 Certain optional BIND features have additional library dependencies. These
 include libxml2 and libjson-c for statistics, libmaxminddb for
 geolocation, libfstrm and libprotobuf-c for DNSTAP, and libidn2 for
 internationalized domain name conversion.
 ISC regularly tests BIND on many operating systems and architectures, but
 lacks the resources to test all of them. Consequently, ISC is only able to
 offer support on a "best effort" basis for some.
 Regularly tested platforms
 As of Dec 2019, BIND 9.15 is fully supported and regularly tested on the
 following systems:
  * Debian 9, 10
  * Ubuntu LTS 16.04, 18.04
  * Fedora 31
  * Red Hat Enterprise Linux / CentOS 7, 8
  * FreeBSD 11.3, 12.0
  * OpenBSD 6.5
  * Alpine Linux
 The amd64, i386, armhf and arm64 CPU architectures are all fully
 supported.
 Best effort
 The following are platforms on which BIND is known to build and run. ISC
 makes every effort to fix bugs on these platforms, but may be unable to do
 so quickly due to lack of hardware, less familiarity on the part of
 engineering staff, and other constraints. With the exception of Windows
 Server 2012 R2, none of these are tested regularly by ISC.
  * Windows Server 2012 R2, 2016 / x64
  * Windows 10 / x64
  * macOS 10.12+
  * Solaris 11
  * NetBSD
  * Other Linux distributions still supported by their vendors, such as:
      + Ubuntu 19.04+
      + Gentoo
      + Arch Linux
  * OpenWRT/LEDE 17.01+
  * Other CPU architectures (mips, mipsel, sparc, ...)
 Community maintained
 These systems may not all have the required dependencies for building BIND
 easily available, although it will be possible in many cases to compile
 those directly from source. The community and interested parties may wish
 to help with maintenance, and we welcome patch contributions, although we
 cannot guarantee that we will accept them. All contributions will be
 assessed against the risk of adverse effect on officially supported
 platforms.
  * Platforms past or close to their respective EOL dates, such as:
      + Ubuntu 14.04, 18.10
      + CentOS 6
      + Debian Jessie
      + FreeBSD 10.x
 Unsupported platforms
 These are platforms on which BIND 9.15 is known not to build or run:
  * Platforms without at least OpenSSL 1.0.2
  * Windows 10 / x86
  * Windows Server 2012 and older
  * Solaris 10 and older
  * Platforms that don't support IPv6 Advanced Socket API (RFC 3542)
  * Platforms that don't support atomic operations (via compiler or
    library)
  * Linux without NPTL (Native POSIX Thread Library)
  * Platforms on which libuv cannot be compiled

 engineering staff, and other constraints. With the exception of Windows
 Server 2012 R2, none of these are tested regularly by ISC.
 * Windows Server 2012 R2, 2016 / x64
 * Windows 10 / x64
 * macOS 10.12+
 * Solaris 11
 * NetBSD
 * Other Linux distributions still supported by their vendors, such as:
    * Ubuntu 19.04+
    * Gentoo
    * Arch Linux
 * OpenWRT/LEDE 17.01+
 * Other CPU architectures (mips, mipsel, sparc, ...)
 ### Community maintained
 These systems may not all have the required dependencies for building BIND
 easily available, although it will be possible in many cases to compile
 those directly from source. The community and interested parties may wish
 to help with maintenance, and we welcome patch contributions, although we
 cannot guarantee that we will accept them.  All contributions will be
 assessed against the risk of adverse effect on officially supported
 platforms.
 * Platforms past or close to their respective EOL dates, such as:
    * Ubuntu 14.04, 18.10
    * CentOS 6
    * Debian Jessie
    * FreeBSD 10.x
 ## Unsupported platforms
 These are platforms on which BIND 9.15 is known *not* to build or run:
 * Platforms without at least OpenSSL 1.0.2
 * Windows 10 / x86
 * Windows Server 2012 and older
 * Solaris 10 and older
 * Platforms that don't support IPv6 Advanced Socket API (RFC 3542)
 * Platforms that don't support atomic operations (via compiler or library)
 * Linux without NPTL (Native POSIX Thread Library)
 * Platforms on which `libuv` cannot be compiled

 Portions of BIND that are written in Python, including dnssec-keymgr,
 dnssec-coverage, dnssec-checkds, and some of the system tests, require the
 argparse, ply and distutils.core modules to be available. argparse is a
 standard module as of Python 2.7 and Python 3.2. ply is available from
 https://pypi.python.org/pypi/ply. distutils.core is required for
 installation.
 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.
 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 libraries: libxml2 http://xmlsoft.org or json-c
 https://github.com/json-c/json-c. If these are installed at a nonstandard
 location, then:
  * for libxml2, specify the prefix using --with-libxml2=/prefix,
  * for json-c, adjust PKG_CONFIG_PATH.
 To support compression on the HTTP statistics channel, the server must be
 linked against libzlib. If this is installed in a nonstandard location,
 specify the prefix using --with-zlib=/prefix.
 To support storing configuration data for runtime-added zones in an LMDB
 database, the server must be linked with liblmdb. If this is installed in
 a nonstandard location, specify the prefix using with-lmdb=/prefix.
 To support MaxMind GeoIP2 location-based ACLs, the server must be linked
 with libmaxminddb. This is turned on by default if the library is found;
 if the library is installed in a nonstandard location, specify the prefix
 using --with-maxminddb=/prefix. GeoIP2 support can be switched off with
 --disable-geoip.
 For DNSTAP packet logging, you must have installed libfstrm https://
 github.com/farsightsec/fstrm and libprotobuf-c https://
 developers.google.com/protocol-buffers, and BIND must be configured with
 --enable-dnstap.

 Most notes in the CHANGES file include a reference to a bug report or
 issue number. Prior to 2018, these were usually of the form [RT #NNN] and
 referred to entries in the "bind9-bugs" RT database, which was not open to
 the public. More recent entries use the form [GL #NNN] or, less often, [GL
 !NNN], which, respectively, refer to issues or merge requests in the
 GitLab database. Most of these are publicly readable, unless they include
 information which is confidential or security sensitive.
 To look up a GitLab issue by its number, use the URL https://
 gitlab.isc.org/isc-projects/bind9/issues/NNN. To look up a merge request,
 use https://gitlab.isc.org/isc-projects/bind9/merge_requests/NNN.
 In rare cases, an issue or merge request number may be followed with the
 letter "P". This indicates that the information is in the private ISC
 GitLab instance, which is not visible to the public.

 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.
 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 libraries: `libxml2`
 [http://xmlsoft.org](http://xmlsoft.org) or `json-c`
 [https://github.com/json-c/json-c](https://github.com/json-c/json-c).
 If these are installed at a nonstandard location, then:
 * for `libxml2`, specify the prefix using `--with-libxml2=/prefix`,
 * for `json-c`, adjust `PKG_CONFIG_PATH`.
 To support compression on the HTTP statistics channel, the server must be
 linked against `libzlib`.  If this is installed in a nonstandard location,
 specify the prefix using `--with-zlib=/prefix`.
 To support storing configuration data for runtime-added zones in an LMDB
 database, the server must be linked with liblmdb. If this is installed in a
 nonstandard location, specify the prefix using `with-lmdb=/prefix`.
 To support MaxMind GeoIP2 location-based ACLs, the server must be linked
 with `libmaxminddb`. This is turned on by default if the library is
 found; if the library is installed in a nonstandard location,
 specify the prefix using `--with-maxminddb=/prefix`. GeoIP2 support
 can be switched off with `--disable-geoip`.
 For DNSTAP packet logging, you must have installed `libfstrm`
 [https://github.com/farsightsec/fstrm](https://github.com/farsightsec/fstrm)
 and `libprotobuf-c`
 [https://developers.google.com/protocol-buffers](https://developers.google.com/protocol-buffers),
 and BIND must be configured with `--enable-dnstap`.

 'argparse' is a standard module as of Python 2.7 and Python 3.2.
 'ply' is available from [https://pypi.python.org/pypi/ply](https://pypi.python.org/pypi/ply).

 #### Bug report identifiers
 Most notes in the CHANGES file include a reference to a bug report or
 issue number. Prior to 2018, these were usually of the form `[RT #NNN]`
 and referred to entries in the "bind9-bugs" RT database, which was not open
 to the public. More recent entries use the form `[GL #NNN]` or, less often,
 `[GL !NNN]`, which, respectively, refer to issues or merge requests in the
 GitLab database. Most of these are publicly readable, unless they include
 information which is confidential or security sensitive.
 To look up a GitLab issue by its number, use the URL
 [https://gitlab.isc.org/isc-projects/bind9/issues/NNN](https://gitlab.isc.org/isc-projects/bind9/issues).
 To look up a merge request, use
 [https://gitlab.isc.org/isc-projects/bind9/merge_requests/NNN](https://gitlab.isc.org/isc-projects/bind9/merge_requests).
 In rare cases, an issue or merge request number may be followed with the
 letter "P". This indicates that the information is in the private ISC
 GitLab instance, which is not visible to the public.

 The input keys can be specified in a number of ways:
 .PP
 By default,
 \fBdnssec\-dsfromkey\fR
 reads a key file named like

 With the
 \fB\-f \fR\fB\fIfile\fR\fR
 option,
 \fBdnssec\-dsfromkey\fR
 reads keys from a zone file or partial zone file (which can contain just the DNSKEY records)\&.
