Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + Everyone is permitted to copy and distribute verbatim copies + of this license document, but changing it is not allowed. + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number.

All three can +be built from this repository. However, all three released separately as .tar.bz2, +.deb and .rpm. + +COMPILING Authoritative Server +------------------------------ +The PowerDNS Authoritative Server depends on Boost, OpenSSL and requires a +compiler with C++-2011 support. + +On Debian 9, the following is useful: + +```sh +apt install g++ libboost-all-dev libtool make pkg-config default-libmysqlclient-dev libssl-dev virtualenv +``` + +When building from git, the following packages are also required: + +```sh +apt install autoconf automake ragel bison flex +``` + +For Ubuntu 18.04 (Bionic Beaver), the following packages should be installed: + +```sh +apt install libcurl4-openssl-dev luajit lua-yaml-dev libyaml-cpp-dev libtolua-dev lua5.3 autoconf automake ragel bison flex g++ libboost-all-dev libtool make pkg-config libssl-dev virtualenv lua-yaml-dev libyaml-cpp-dev libluajit-5.1-dev libcurl4 gawk +# For DNSSEC ed25519 (algorithm 15) support with --with-libsodium +apt install libsodium-dev +# If using the gmysql (Generic MySQL) backend +apt install default-libmysqlclient-dev +# If using the gpgsql (Generic PostgreSQL) backend +apt install postgresql-server-dev-10 +# If using --enable-systemd (will create the service scripts so it can be managed with systemctl/service) +apt install libsystemd0 libsystemd-dev +# If using the geoip backend +apt install libmaxminddb-dev libmaxminddb0 libgeoip1 libgeoip-dev +``` + +Then generate the configure file: + +```sh +autoreconf -vi +``` + +To compile a very clean version, use: + +```sh +./configure --with-modules="" --without-lua --disable-lua-records +make +# make install +``` + +This generates a PowerDNS Authoritative Server binary with no modules built in. + +See https://doc.powerdns.com/authoritative/backends/index.html for a list of available modules. + +When `./configure` is run without `--with-modules`, the bind and gmysql module are +built-in by default and the pipe-backend is compiled for runtime loading. + +To add multiple modules, try: + +```sh +./configure --with-modules="bind gmysql gpgsql" +``` + +Note that you will need the development headers for PostgreSQL as well in this case. + +See https://doc.powerdns.com/authoritative/appendices/compiling.html for more details. + +If you run into C++11-related symbol trouble, please try passing `CPPFLAGS=-D_GLIBCXX_USE_CXX11_ABI=0` (or 1) to `./configure` to make sure you are compatible with the installed dependencies. + +Compiling the Recursor +---------------------- +See [README.md](pdns/recursordist/README.md) in `pdns/recursordist/`. + +Compiling dnsdist +----------------- +See [README-dnsdist.md](pdns/README-dnsdist.md) in `pdns/`. + +Building the HTML documentation +------------------------------- + +The HTML documentation (as seen [on the PowerDNS docs site](https://doc.powerdns.com/authoritative/)) is built from ReStructured Text (rst) files located in `docs`. They are compiled into HTML files using [Sphinx](http://www.sphinx-doc.org/en/master/index.html), a documentation generator tool which is built in Python. + +**Using a normal Python installation** + +For those simply contributing to the documentation, this avoids needing to install the various build +tools and other dependencies. + +Install Python 2.7 or Python 3 (preferable) if you don't yet have it installed. On some operating +systems you may also have to install `python3-pip` or similarly named. + +Ubuntu 16.04 / 18.04 + +```sh +apt update +apt install python3 python3-pip python3-venv +``` + +macOS (using homebrew) + +```sh +brew install python3 +``` + +Update your `pip` and install/update `virtualenv` to avoid problems: + +```sh +# for python2, use "pip" instead of "pip3" +pip3 install -U pip +pip3 install -U virtualenv +``` + +Enter the repository's `docs` folder, set up the virtualenv, and install the requirements + +```sh +cd docs +# for python2, use "virtualenv .venv" instead +python3 -m venv .venv +source .venv/bin/activate +# The virtualenv may use an older pip, so upgrade it again +pip3 install -U pip setuptools setuptools-git +# Now you can install the requirements +pip3 install -r requirements.txt +``` + +Finally, you can build the documentation: + +```sh +sphinx-build . html-docs +``` + +Note: If your shell has problems finding sphinx-build, try using `.venv/bin/sphinx-build` instead. + +The HTML documentation is now available in `html-docs`. + +**Using the build tools** + +This method is preferable for those who already have a working build environment for PowerDNS. + +Install the dependencies under "COMPILING", and run autoreconf if you haven't already: + +```sh +autoreconf -vi +``` + +Enter the `docs` folder, and use make to build the HTML docs. + +``` +cd docs +make html-docs +``` + +The HTML documentation will now be available in `html-docs`. + +Solaris Notes +------------- +Use a recent gcc. OpenCSW is a good source, as is Solaris 11 IPS. + +If you encounter problems with the Solaris make, gmake is advised. + +FreeBSD Notes +------------- +You need to compile using gmake - regular make only appears to work, but doesn't in fact. Use gmake, not make. + +The clang compiler installed through FreeBSD's package manager does not expose all of the C++11 features needed under `std=gnuc++11`. Force the compiler to use `std=c++11` mode instead. + +```sh +export CXXFLAGS=-std=c++11 +``` + +macOS Notes +----------- +PowerDNS Authoritative Server is available through Homebrew: + +``` +brew install pdns +``` + +If you want to compile yourself, the dependencies can be installed using +Homebrew. You need to tell configure where to find OpenSSL, too. + +```sh +brew install boost lua pkg-config ragel openssl +./configure --with-modules="" --with-lua PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig +make -j4 +``` + +Additionally, for PostgreSQL support, run `brew install postgresql` and add `--with-modules="gpgsql"` to `./configure`. +For MySQL support, run `brew install mariadb` and add `--with-modules="gmysql"` to `./configure`. + +Linux notes +----------- +None really. diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..e26c915 --- /dev/null +++ b/Makefile.am @@ -0,0 +1,16 @@ +SUBDIRS = ext modules pdns codedocs docs + +EXTRA_DIST = \ + INSTALL \ + NOTICE \ + README \ + COPYING \ + codedocs/doxygen.conf \ + contrib/powerdns.solaris.init.d \ + pdns/named.conf.parsertest \ + regression-tests/zones/unit.test \ + builder-support/gen-version + +ACLOCAL_AMFLAGS = -I m4 + +dvi: # do nothing to build dvi diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..b87c639 --- /dev/null +++ b/Makefile.in @@ -0,0 +1,984 @@ +# Makefile.in generated by automake 1.15.1 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994-2017 Free Software Foundation, Inc. + +# This Makefile.in is free software;

However, all three released separately as .tar.bz2, +.deb and .rpm. + +COMPILING Authoritative Server +------------------------------ +The PowerDNS Authoritative Server depends on Boost, OpenSSL and requires a +compiler with C++-2011 support. + +On Debian 9, the following is useful: + +```sh +apt install g++ libboost-all-dev libtool make pkg-config default-libmysqlclient-dev libssl-dev virtualenv +``` + +When building from git, the following packages are also required: + +```sh +apt install autoconf automake ragel bison flex +``` + +For Ubuntu 18.04 (Bionic Beaver), the following packages should be installed: + +```sh +apt install libcurl4-openssl-dev luajit lua-yaml-dev libyaml-cpp-dev libtolua-dev lua5.3 autoconf automake ragel bison flex g++ libboost-all-dev libtool make pkg-config libssl-dev virtualenv lua-yaml-dev libyaml-cpp-dev libluajit-5.1-dev libcurl4 gawk +# For DNSSEC ed25519 (algorithm 15) support with --with-libsodium +apt install libsodium-dev +# If using the gmysql (Generic MySQL) backend +apt install default-libmysqlclient-dev +# If using the gpgsql (Generic PostgreSQL) backend +apt install postgresql-server-dev-10 +# If using --enable-systemd (will create the service scripts so it can be managed with systemctl/service) +apt install libsystemd0 libsystemd-dev +# If using the geoip backend +apt install libmaxminddb-dev libmaxminddb0 libgeoip1 libgeoip-dev +``` + +Then generate the configure file: + +```sh +autoreconf -vi +``` + +To compile a very clean version, use: + +```sh +./configure --with-modules="" --without-lua --disable-lua-records +make +# make install +``` + +This generates a PowerDNS Authoritative Server binary with no modules built in. + +See https://doc.powerdns.com/authoritative/backends/index.html for a list of available modules. + +When `./configure` is run without `--with-modules`, the bind and gmysql module are +built-in by default and the pipe-backend is compiled for runtime loading. + +To add multiple modules, try: + +```sh +./configure --with-modules="bind gmysql gpgsql" +``` + +Note that you will need the development headers for PostgreSQL as well in this case. + +See https://doc.powerdns.com/authoritative/appendices/compiling.html for more details. + +If you run into C++11-related symbol trouble, please try passing `CPPFLAGS=-D_GLIBCXX_USE_CXX11_ABI=0` (or 1) to `./configure` to make sure you are compatible with the installed dependencies. + +Compiling the Recursor +---------------------- +See [README.md](pdns/recursordist/README.md) in `pdns/recursordist/`. + +Compiling dnsdist +----------------- +See [README-dnsdist.md](pdns/README-dnsdist.md) in `pdns/`. + +Building the HTML documentation +------------------------------- + +The HTML documentation (as seen [on the PowerDNS docs site](https://doc.powerdns.com/authoritative/)) is built from ReStructured Text (rst) files located in `docs`. They are compiled into HTML files using [Sphinx](http://www.sphinx-doc.org/en/master/index.html), a documentation generator tool which is built in Python. + +**Using a normal Python installation** + +For those simply contributing to the documentation, this avoids needing to install the various build +tools and other dependencies. + +Install Python 2.7 or Python 3 (preferable) if you don't yet have it installed. On some operating +systems you may also have to install `python3-pip` or similarly named. + +Ubuntu 16.04 / 18.04 + +```sh +apt update +apt install python3 python3-pip python3-venv +``` + +macOS (using homebrew) + +```sh +brew install python3 +``` + +Update your `pip` and install/update `virtualenv` to avoid problems: + +```sh +# for python2, use "pip" instead of "pip3" +pip3 install -U pip +pip3 install -U virtualenv +``` + +Enter the repository's `docs` folder, set up the virtualenv, and install the requirements + +```sh +cd docs +# for python2, use "virtualenv .venv" instead +python3 -m venv .venv +source .venv/bin/activate +# The virtualenv may use an older pip, so upgrade it again +pip3 install -U pip setuptools setuptools-git +# Now you can install the requirements +pip3 install -r requirements.txt +``` + +Finally, you can build the documentation: + +```sh +sphinx-build . html-docs +``` + +Note: If your shell has problems finding sphinx-build, try using `.venv/bin/sphinx-build` instead. + +The HTML documentation is now available in `html-docs`. + +**Using the build tools** + +This method is preferable for those who already have a working build environment for PowerDNS. + +Install the dependencies under "COMPILING", and run autoreconf if you haven't already: + +```sh +autoreconf -vi +``` + +Enter the `docs` folder, and use make to build the HTML docs. + +``` +cd docs +make html-docs +``` + +The HTML documentation will now be available in `html-docs`. + +Solaris Notes +------------- +Use a recent gcc. OpenCSW is a good source, as is Solaris 11 IPS. + +If you encounter problems with the Solaris make, gmake is advised. + +FreeBSD Notes +------------- +You need to compile using gmake - regular make only appears to work, but doesn't in fact. Use gmake, not make. + +The clang compiler installed through FreeBSD's package manager does not expose all of the C++11 features needed under `std=gnuc++11`. Force the compiler to use `std=c++11` mode instead. + +```sh +export CXXFLAGS=-std=c++11 +``` + +macOS Notes +----------- +PowerDNS Authoritative Server is available through Homebrew: + +``` +brew install pdns +``` + +If you want to compile yourself, the dependencies can be installed using +Homebrew. You need to tell configure where to find OpenSSL, too. + +```sh +brew install boost lua pkg-config ragel openssl +./configure --with-modules="" --with-lua PKG_CONFIG_PATH=/usr/local/opt/openssl/lib/pkgconfig +make -j4 +``` + +Additionally, for PostgreSQL support, run `brew install postgresql` and add `--with-modules="gpgsql"` to `./configure`. +For MySQL support, run `brew install mariadb` and add `--with-modules="gmysql"` to `./configure`. + +Linux notes +----------- +None really. diff --git a/aclocal.m4 b/aclocal.m4 new file mode 100644 index 0000000..6ba8786 --- /dev/null +++ b/aclocal.m4 @@ -0,0 +1,1558 @@ +# generated automatically by aclocal 1.15.1 -*- Autoconf -*- + +# Copyright (C) 1996-2017 Free Software Foundation, Inc. + +# This file is free software; the Free Software Foundation +# gives unlimited permission to copy and/or distribute it, +# with or without modifications, as long as this notice is preserved. + +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY, to the extent permitted by law; without +# even the implied warranty of MERCHANTABILITY or FITNESS FOR A +# PARTICULAR PURPOSE. + +m4_ifndef([AC_CONFIG_MACRO_DIRS], [m4_defun([_AM_CONFIG_MACRO_DIRS], [])m4_defun([AC_CONFIG_MACRO_DIRS], [_AM_CONFIG_MACRO_DIRS($@)])]) +m4_ifndef([AC_AUTOCONF_VERSION], + [m4_copy([m4_PACKAGE_VERSION], [AC_AUTOCONF_VERSION])])dnl +m4_if(m4_defn([AC_AUTOCONF_VERSION]), [2.69],, +[m4_warning([this file was generated for autoconf 2.69. +You have another version of autoconf.

+ +YaHTTP aims to be a pure http request/response parser that has no IO ties. It is intended to be used on small-footprint applications and other utilities that want to use HTTP over something else than network IO. + +[![Build Status](https://travis-ci.org/cmouse/yahttp.svg?branch=master)](https://travis-ci.org/cmouse/yahttp) +[![Coverity Scan Build Status](https://scan.coverity.com/projects/2161/badge.svg)](https://scan.coverity.com/projects/2161) +[![Coverage Status](https://coveralls.io/repos/github/cmouse/yahttp/badge.svg)](https://coveralls.io/github/cmouse/yahttp) + +WARNINGS +-------- +If you are upgrading from version before May 02, 2014 - *PLEASE BE SURE TO CHECK THAT EVERYTHING WORKS AS EXPECTED*. There has been complete overhaul of the library and many things have changed. + +NOTES +----- +Do not use resp = req, or resp(req) to build the response object, despite it being supported. This will cause request headers to get duplicated. Also, you *must* set response#version to request#version if you intend to support older than HTTP/1.1 clients. Set response#status to at least 200, it won't be done for you. No Server or Product token is sent either, you can add those if you want. + +If you do not want to send chunked responses, set content-length header. Setting this header will always disable chunked responses. This will also happen if you downgrade your responses to version 10 or 9. + +Integration guide +----------------- + +Here are some instructions on how to integrate YaHTTP into your project. + +With automake and libtool +------------------------- + +If you don't need router or any of the C++11 features, you can just create empty yahttp-config.h, or symlink it to your project's config.h for the yahttp.hpp to include. Then just put this stuff into it's own folder and create Makefile.am with following contents (you can change the compilation flags): + +``` +noinst_LTLIBRARIES=libyahttp.la +libyahttp_la_CXXFLAGS=$(RELRO_CFLAGS) $(PIE_CFLAGS) -D__STRICT_ANSI__ +libyahttp_la_SOURCES=cookie.hpp exception.hpp reqresp.cpp reqresp.hpp router.cpp router.hpp url.hpp utility.hpp yahttp.hpp +``` + +You can define RELRO and PIE to match your project. + +To compile your project use -Lpath/to/yahttp -lyahttp + +If you need router, additionally check for boost or C++11 and replace yahttp-config.h to config.h in yahttp.hpp or add relevant options to your compiler CXXFLAGS. See below for the flags. + +Without automake +---------------- + +Create simple Makefile with contents for C++11: + +``` +OBJECTS=reqresp.o router.o +CXX=gcc +CXXFLAGS=-W -Wall -DHAVE_CXX11 -std=c++11 +``` + +Or create simple Makefile with contents for boost: + +``` +OBJECTS=reqresp.o router.o +CXX=gcc +CXXFLAGS=-W -Wall -DHAVE_BOOST +``` + +Or if you don't need either one, just: + +``` +OBJECTS=reqresp.o +CXX=gcc +CXXFLAGS=-W -Wall +``` + +YaHTTP include files can be placed where the rest of your includes are.

+Note: shortly before the 3.2 release of PowerDNS, Fredrik Danerklinkt +(author of this Luabackend) opened https://github.com/fredan/luabackend +and is doing development there. + + +http://www.lua.org for more information about what Lua really is. + + +This backend is just a "glue" between PowerDNS and your own Lua application. + +What this means is that you can not have a working setup that can serve you +dns-questions directly from start. What you need to do is to program your own +backend completely in Lua! Which database server to use etc is now up to you! + +What you have here is the possibility to make your own "dns-server" without the +knowledge of programming in c/c++. + +There is one thing that needs to be said. Remember that each thread +PowerDNS launches of this backend is completely different so they cannot +share information between each other! + +You will need some kind of a database that can be shared for this. + +All the functionnames that PowerDNS accept for a backend should be the same +in your Lua script, in lowercase. Also, the parameters should be in the same +order. Where there is a structure in c/c++ there is a table in the Lua backend. +This is also true for return values. A few functions expect that you return a +table in a table. + + +============= +NEW FUNCTIONS +============= + +There is a couple of new functions for you to use in Lua: + +---------------------------------------- +logger(log_facility, "your", "messages") +---------------------------------------- + +All these log_facilities is available: +log_all, log_ntlog, log_alert, log_critical, log_error, log_warning, log_notice, +log_info, log_debug, log_none + + +----------- +dnspacket() +----------- + +This will give you back three parameters with +remote_ip, remote_port and local_ip in that order. + +Can only be used in the functions list() and getsoa(). + + +------------------------ +getarg("your_parameter") +------------------------ + +This one tries to get the value of the name "lua-your_parameter" from the +pdns.conf file. + + +------------------------ +mustdo("your_parameter") +------------------------ + +This is the same as getarg() but return a boolean instead of a string. + + +You also have all the different QTypes in a table called 'QTypes'. + + +==================== +WHAT HAS BEEN TESTED +==================== + +The only functionality of the minimal functions except zone-transfer has +been tested. + +In the included powerdns-luabackend.lua file there is a example of how +this can be done. Note that this is more or less a static example since +there is no possibility for each thread to know when something has changed. + +However, you can run 'pdns_control reload' and it should reload the hole thing +from scratch (does not work for the moment, PowerDNS only calls two thread with +the reload command - not all of them). + + +=========================================== +WHAT YOU WILL FIND UNDER THE TEST DIRECTORY +=========================================== + +The script 'pdns' is used to test the server on the ip address '127.0.0.1' with +the port 5300. You should be able to run the following test with the included +'powerdns-luabackend.lua' file: + +$dig any www.test.com @127.0.0.1 -p5300 +multiline +; <<>> DiG 9.7.3 <<>> any www.test.com @127.0.0.1 -p5300 +multiline +;; global options: +cmd +;; Got answer: +;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 1001 +;; flags: qr aa rd; QUERY: 1, ANSWER: 3, AUTHORITY: 0, ADDITIONAL: 0 +;; WARNING: recursion requested but not available + +;; QUESTION SECTION: +;www.test.com.

For example: + +lua-f_lookup = mynewfunction + +will call the function 'mynewfunction' for the lookup-routine. + +If you want your own configuration parameters you can have that too. +Just call the function getarg("my_parameter") and it will return the value +of 'lua-my_parameter'. For boolean you use the function mustdo("my_parameter"). + + +============================== +YOUR OWN ERROR FUNCTION IN LUA +============================== + +You can have an error function in Lua when Lua gives back a error. + +First make your error function then you put this in pdns.conf: + +lua-f_exec_error = + + +====== +DNSSEC +====== + +You can have full dnssec support in our Lua application. You should note the +following regarding this: + +You don't have to implement the function 'updateDNSSECOrderAndAuth' since the +default code will work correctly for you via the backend itself. + +The functions activateDomainKey and deactivateDomainKey can be implemented via a +new function called updateDomainKey, which has three parameters (the other two +has only two parameters) where the third is a boolean which is true or false +depending on which function that was called from the beginning. + + +======================= +INFORMATION FOR LOGGING +======================= + +If you have the parameter 'query-logging' or 'lua-logging-query' set to +true/yes/on, then you will see what is happening in each function when PowerDNS +calls them. + +This can, hopefully, help you with some debugging if you run into some kind of +trouble with your Lua application. + + +=============== +ASKING QUESTION +=============== + +You can send question about this backend to >dev/null first and if you don't get any +answer from that you can try to send them to me at fredan-pdns@fredan.org + +Fredrik Danerklint. \ No newline at end of file diff --git a/modules/luabackend/dnssec.cc b/modules/luabackend/dnssec.cc new file mode 100644 index 0000000..076df6f --- /dev/null +++ b/modules/luabackend/dnssec.cc @@ -0,0 +1,603 @@ +/* + * This file is part of PowerDNS or dnsdist. + * Copyright -- PowerDNS.COM B.V. and its contributors + * originally authored by Fredrik Danerklint + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of version 2 of the GNU General Public License as + * published by the Free Software Foundation. + * + * In addition, for the avoidance of any doubt, permission is granted to + * link this program with OpenSSL and to (re)distribute the binaries + * produced as the result of such linking. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It is licensed to you under the terms of the GPL version 2. + + \section overview High level overview + MTasker is designed to support very simple cooperative multitasking to facilitate writing + code that would ordinarily require a statemachine, for which the author does not consider + himself smart enough. + + This class does not perform any magic it only makes calls to makecontext() and swapcontext(). + Getting the details right however is complicated and MTasker does that for you. + + If preemptive multitasking or more advanced concepts such as semaphores, locks or mutexes + are required, the use of POSIX threads is advised. + + MTasker is designed to offer the performance of statemachines while maintaining simple thread semantics. It is not + a replacement for a full threading system. + + \section compatibility Compatibility + MTasker is only guaranteed to work on Linux with glibc 2.2.5 and higher. It does not work on FreeBSD and notably, + not on Red Hat 6.0. It may work on Solaris, please test. + + \section concepts Concepts + + There are two important concepts, the 'kernel' and the 'thread'. Each thread starts out as a function, + which is passed to MTasker::makeThread(), together with a possible argument. + + This function is now free to do whatever it wants, but realise that MTasker implements cooperative + multitasking, which means that the coder has the responsibility of not taking the CPU overly long. + Other threads can only get the CPU if MTasker::yield() is called or if a thread sleeps to wait for an event, + using the MTasker::waitEvent() method. + + \section kernel The Kernel + The Kernel consists of functions that do housekeeping, but also of code that the client coder + can call to report events. A minimal kernel loop looks like this: + \code + for(;;) { + MT.schedule(); + if(MT.noProcesses()) // exit if no processes are left + break; + } + \endcode + + The kernel typically starts from the main() function of your program. New threads are also + created from the kernel. This can also happen before entering the main loop.
