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 Library 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. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) 19yy - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - 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. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) 19yy name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License.

This file is offered as-is, +without warranty of any kind. + +Basic Installation +================== + + Briefly, the shell commands `./configure; make; make install' should +configure, build, and install this package. The following +more-detailed instructions are generic; see the `README' file for +instructions specific to this package. Some packages provide this +`INSTALL' file but do not implement all of the features documented +below. The lack of an optional feature in a given package is not +necessarily a bug. More recommendations for GNU packages can be found +in *note Makefile Conventions: (standards)Makefile Conventions. + + The `configure' shell script attempts to guess correct values for +various system-dependent variables used during compilation. It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. Caching is +disabled by default to prevent problems with accidental use of stale +cache files. + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You need `configure.ac' if +you want to change it or regenerate `configure' using a newer version +of `autoconf'. + + The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. + + Running `configure' might take a while. While running, it prints + some messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package, generally using the just-built uninstalled binaries. + + 4. Type `make install' to install the programs and any data files and + documentation. When installing into a prefix owned by root, it is + recommended that the package be configured and built as a regular + user, and only the `make install' phase executed with root + privileges. + + 5. Optionally, type `make installcheck' to repeat any self-tests, but + this time using the binaries in their final installed location. + This target does not install anything. Running this target as a + regular user, particularly if the prior `make install' required + root privileges, verifies that the installation completed + correctly. + + 6. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + + 7. Often, you can also type `make uninstall' to remove the installed + files again. In practice, not all packages have tested that + uninstallation works correctly, even though it is required by the + GNU Coding Standards. + + 8. Some packages, particularly those that use Automake, provide `make + distcheck', which can by used by developers to test that all other + targets like `make install' and `make uninstall' work correctly. + This target is generally not run by end users. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c99 CFLAGS=-g LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you can use GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. This +is known as a "VPATH" build. + + With a non-GNU `make', it is safer to compile the package for one +architecture at a time in the source code directory. After you have +installed the package for one architecture, use `make distclean' before +reconfiguring for another architecture. + + On MacOS X 10.5 and later systems, you can create libraries and +executables that work on multiple system types--known as "fat" or +"universal" binaries--by specifying multiple `-arch' options to the +compiler but only a single `-arch' option to the preprocessor. Like +this: + + ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ + CPP="gcc -E" CXXCPP="g++ -E" + + This is not guaranteed to produce working output in all cases, you +may have to build one architecture at a time and combine the results +using the `lipo' tool if you have problems. + +Installation Names +================== + + By default, `make install' installs the package's commands under +`/usr/local/bin', include files under `/usr/local/include', etc. You +can specify an installation prefix other than `/usr/local' by giving +`configure' the option `--prefix=PREFIX', where PREFIX must be an +absolute file name. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +pass the option `--exec-prefix=PREFIX' to `configure', the package uses +PREFIX as the prefix for installing programs and libraries. +Documentation and other data files still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=DIR' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. In general, the +default for these options is expressed in terms of `${prefix}', so that +specifying just `--prefix' will affect all of the other directory +specifications that were not explicitly provided. + + The most portable way to affect installation locations is to pass the +correct locations to `configure'; however, many packages provide one or +both of the following shortcuts of passing variable assignments to the +`make install' command line to change installation locations without +having to reconfigure or recompile. + + The first method involves providing an override variable for each +affected directory. For example, `make install +prefix=/alternate/directory' will choose an alternate location for all +directory configuration variables that were expressed in terms of +`${prefix}'. Any directories that were specified during `configure', +but not in terms of `${prefix}', must each be overridden at install +time for the entire installation to be relocated. The approach of +makefile variable overrides for each directory variable is required by +the GNU Coding Standards, and ideally causes no recompilation. +However, some platforms have known limitations with the semantics of +shared libraries that end up requiring recompilation when using this +method, particularly noticeable in packages that use GNU Libtool. + + The second method involves providing the `DESTDIR' variable. For +example, `make install DESTDIR=/alternate/directory' will prepend +`/alternate/directory' before all installation names. The approach of +`DESTDIR' overrides is not required by the GNU Coding Standards, and +does not work on platforms that have drive letters. On the other hand, +it does better at avoiding recompilation issues, and works well even +when some directory options were not specified in terms of `${prefix}' +at `configure' time. + +Optional Features +================= + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + + Some packages offer the ability to configure how verbose the +execution of `make' will be. For these packages, running `./configure +--enable-silent-rules' sets the default to minimal output, which can be +overridden with `make V=1'; while running `./configure +--disable-silent-rules' sets the default to verbose, which can be +overridden with `make V=0'. + +Particular systems +================== + + On HP-UX, the default C compiler is not ANSI C compatible. If GNU +CC is not installed, it is recommended to use the following options in +order to use an ANSI C compiler: + + ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" + +and if that doesn't work, install pre-built binaries of GCC for HP-UX. + + HP-UX `make' updates targets which have the same time stamps as +their prerequisites, which makes it generally unusable when shipped +generated files such as `configure' are involved. Use GNU `make' +instead. + + On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot +parse its `' header file. The option `-nodtk' can be used as +a workaround. If GNU CC is not installed, it is therefore recommended +to try + + ./configure CC="cc" + +and if that doesn't work, try + + ./configure CC="cc -nodtk" + + On Solaris, don't put `/usr/ucb' early in your `PATH'. This +directory contains several dysfunctional programs; working variants of +these programs are available in `/usr/bin'. So, if you need `/usr/ucb' +in your `PATH', put it _after_ `/usr/bin'. + + On Haiku, software installed for all users goes in `/boot/common', +not `/usr/local'. It is recommended to use the following options: + + ./configure --prefix=/boot/common + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS + KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the option `--target=TYPE' to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +causes the specified `gcc' to be used as the C compiler (unless it is +overridden in the site shell script). + +Unfortunately, this technique does not work for `CONFIG_SHELL' due to +an Autoconf limitation. Until the limitation is lifted, you can use +this workaround: + + CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of all of the options to `configure', and exit. + +`--help=short' +`--help=recursive' + Print a summary of the options unique to this package's + `configure', and exit. The `short' variant lists options used + only in the top level, while the `recursive' variant lists options + also present in any nested packages. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made.

Best of all, +DNSCurve has very low overhead and adds virtually no latency to +queries. + +DNSCurve aims at securing the entire chain down to authoritative +servers. However, it only works with authoritative servers that explicitly +support the protocol. And unfortunately, DNSCurve hasn't received much +adoption yet. + +The DNSCrypt protocol is very similar to DNSCurve, but focuses on +securing communications between a client and its first-level resolver. +While not providing end-to-end security, it protects the local +network (which is often the weakest link in the chain) against +man-in-the-middle attacks. It also provides some confidentiality to +DNS queries. + +The DNSCrypt daemon acts as a DNS proxy between a regular client, like +a DNS cache or an operating system stub resolver, and a DNSCrypt-aware +resolver, like OpenDNS. + +Installation +------------ + +The daemon is known to work on recent versions of OSX, OpenBSD, Bitrig, +NetBSD, Dragonfly BSD, FreeBSD, Linux, iOS (requires a jailbroken +device), and Windows (requires MingW). + +Download the +[latest version](https://github.com/opendns/dnscrypt-proxy/downloads) +and extract it: + + $ bunzip2 -cd dnscrypt-proxy-*.tar.bz2 | tar xvf - + $ cd dnscrypt-proxy-* + +Compile and install it using the standard procedure: + + $ ./configure && make -j2 + # make install + +Replace `-j2` with whatever number of CPU cores you want to use for the +compilation process. + +Running `make -j2 test` in the `src/libnacl` directory is also highly +recommended. + +The proxy will be installed as `/usr/local/sbin/dnscrypt-proxy` by default. + +Command-line switches are documented in the `dnscrypt-proxy(8)` man page. + +Usage +----- + +Having a dedicated system user, with no privileges and with an empty +home directory, is highly recommended. For extra security, DNSCrypt +will chroot() to this user's home directory and drop root privileges +for this user's uid as soon as possible. + +The easiest way to start the daemon is: + + # dnscrypt-proxy --daemonize + +The proxy will accept incoming requests on 127.0.0.1, tag them with an +authentication code, forward them to OpenDNS resolvers, and validate +each answer before passing it to the client. + +Given such a setup, in order to actually start using DNSCrypt, you +need to update your `/etc/resolv.conf` file and replace your current +set of resolvers with: + + nameserver 127.0.0.1 + +Other common command-line switches include: + +* `--daemonize` in order to run the server as a background process. +* `--local-address=[:port]` in order to locally bind a different IP +address than 127.0.0.1 +* `--logfile=` in order to write log data to a dedicated file. By + default, logs are sent to stdout if the server is running in foreground, + and to syslog if it is running in background. +* `--max-active-requests=` to set the maximum number of active + requests. The default value is 250. +* `--pid-file=` in order to store the PID number to a file. +* `--user=` in order to chroot()/drop privileges. + +DNSCrypt comes pre-configured for OpenDNS, although the +`--resolver-address=[:port]`, +`--provider-name=` +and `--provider-key=` can be specified in +order to change the default settings. + +Using DNSCrypt in combination with a DNS cache +---------------------------------------------- + +The DNSCrypt proxy is **not** a DNS cache. This means that incoming +queries will **not** be cached and every single query will require a +round-trip to the upstream resolver. + +For optimal performance, the recommended way of running DNSCrypt is to +run it as a forwarder for a local DNS cache, like `unbound` or +`powerdns-recursor`. + +Both can safely run on the same machine as long as they are listening +to different IP addresses (preferred) or different ports. + +If your DNS cache is `unbound`, all you need is to edit the +`unbound.conf` file and add the following lines at the end of the `server` +section: + + do-not-query-localhost: no + + forward-zone: + name: "." + forward-addr: 127.0.0.1@40 + +The first line is not required if you are using different IP addresses +instead of different ports. + +Then start `dnscrypt-proxy`, telling it to use a specific port (`40`, in +this example): + + # dnscrypt-proxy --local-address=127.0.0.1:40 --daemonize + +IPv6 support +------------ + +IPv6 is fully supported. IPv6 addresses with a port number should be +specified as [ip]:port + + # dnscrypt-proxy --local-address='[::1]:40' --daemonize + +Queries using nonstandard ports / over TCP +------------------------------------------ + +Some routers and firewalls can block outgoing DNS queries or +transparently redirect them to their own resolver. This especially +happens on public Wifi hotspots, such as coffee shops. + +As a workaround, the port number can be changed using +the `--resolver-port=` option. For example, OpenDNS servers +reply to queries sent to ports 53, 443 and 5353. + +By default, dnscrypt-proxy sends outgoing queries to UDP port 443. + +In addition, the DNSCrypt proxy can force outgoing queries to be +sent over TCP. For example, TCP port 443, which is commonly used for +communication over HTTPS, may not be filtered. + +The `--tcp-only` command-line switch forces this behavior. When +an incoming query is received, the daemon immediately replies with a +"response truncated" message, forcing the client to retry over TCP. +The daemon then authenticates the query and forwards it over TCP +to the resolver. + +TCP is slower than UDP, and this workaround should never be used +except when bypassing a filter is actually required. Moreover, +multiple queries over a single TCP connections aren't supported yet. + +EDNS payload size +----------------- + +DNS packets sent over UDP have been historically limited to 512 bytes, +which is usually fine for queries, but sometimes a bit short for +replies. + +Most modern authoritative servers, resolvers and stub resolvers +support the Extension Mechanism for DNS (EDNS) that, among other +things, allows a client to specify how large a reply over UDP can be. + +Unfortunately, this feature is disabled by default on a lot of +operating systems. It has to be explicitly enabled, for example by +adding `options edns0` to the `/etc/resolv.conf` file on most +Unix-like operating systems. + +`dnscrypt-proxy` can transparently rewrite outgoing packets before +authenticating them, in order to add the EDNS0 mechanism. By +default, a conservative payload size of 1280 bytes is advertised. + +This size can be made larger by starting the proxy with the +`--edns-payload-size=` command-line switch. Values up to 4096 +are usually safe. + +A value below or equal to 512 will disable this mechanism, unless a +client sends a packet with an OPT section providing a payload size. + +The `hostip` utility +-------------------- + +The DNSCrypt proxy ships with a simple tool named `hostip` that +resolves a name to IPv4 or IPv6 addresses. + +This tool can be useful for starting some services before +`dnscrypt-proxy`. + +Queries made by `hostip` are not authenticated. + +GUIs for dnscrypt-proxy +----------------------- + +If you need a simple graphical user interface in order to start/stop +the proxy and change your DNS settings, check out the following +projects: + +- [DNSCrypt OSX Client](https://github.com/opendns/dnscrypt-osx-client): +a preferences pane, a menu bar indicator and a service to change the +DNS settings.

The elements + * are singly linked for minimum space and pointer manipulation overhead at + * the expense of O(n) removal for arbitrary elements. New elements can be + * added to the list after an existing element or at the head of the list. + * Elements being removed from the head of the list should use the explicit + * macro for this purpose for optimum efficiency. A singly-linked list may + * only be traversed in the forward direction. Singly-linked lists are ideal + * for applications with large datasets and few or no removals or for + * implementing a LIFO queue. + * + * A list is headed by a single forward pointer (or an array of forward + * pointers for a hash table header). The elements are doubly linked + * so that an arbitrary element can be removed without a need to + * traverse the list. New elements can be added to the list before + * or after an existing element or at the head of the list. A list + * may only be traversed in the forward direction. + * + * A simple queue is headed by a pair of pointers, one the head of the + * list and the other to the tail of the list. The elements are singly + * linked to save space, so elements can only be removed from the + * head of the list. New elements can be added to the list before or after + * an existing element, at the head of the list, or at the end of the + * list. A simple queue may only be traversed in the forward direction. + * + * A tail queue is headed by a pair of pointers, one to the head of the + * list and the other to the tail of the list. The elements are doubly + * linked so that an arbitrary element can be removed without a need to + * traverse the list. New elements can be added to the list before or + * after an existing element, at the head of the list, or at the end of + * the list. A tail queue may be traversed in either direction. + * + * A circle queue is headed by a pair of pointers, one to the head of the + * list and the other to the tail of the list. The elements are doubly + * linked so that an arbitrary element can be removed without a need to + * traverse the list. New elements can be added to the list before or after + * an existing element, at the head of the list, or at the end of the list. + * A circle queue may be traversed in either direction, but has a

Patch from Ka-Hing Cheung. + o When adding or deleting an event from a non-main thread, only wake up the main thread when its behavior actually needs to change. + o Fix some bugs when using the old evdns interfaces to initialize the evdns module. + o Detect errors during bufferevent_connect(). Patch from Christopher Davis. + o Fix compilation for listener.h for C++ - missing extern "C". Patch from Ferenc Szalai. + o Make the event_base_loop() family of functions respect thread-safety better. This should clear up a few hard-to-debug race conditions. + o Fix a bug when using a specialized memory allocator on win32. + o Have the win32 select() backend label TCP-socket-connected events as EV_WRITE, not EV_READ. This should bring it in line with the other backends, and improve portability. Patch from Christopher Davis. + o Stop using enums as arguments or return values when what we mean is a bitfield of enum values. C++ doesn't believe that you can OR two enum values together and get another enum, and C++ takes its typing seriously. Patch from Christopher Davis. + o Add an API to replace all fatal calls to exit() with a user-provided panic function. + o Replace all assert() calls with a variant that is aware of the user-provided logging and panic functions. + o Add a return value to event_assign so that it can fail rather than asserting when the user gives it bad input. event_set still dies on bad input. + o The event_base_new() and event_base_new_with_config() functions now never call exit() on failure. For backward "compatibility", event_init() still does, but more consistently. + o Remove compat/sys/_time.h. It interfered with system headers on HPUX, and its functionality has been subsumed by event2/util.h and util-internal.h. + o Add a new bufferevent_socket_connect_hostname() to encapsulate the resolve-then-connect operation. + o Build kqueue.c correctly on GNU/kFreeBSD platforms. Patch pulled upstream from Debian. + o Alternative queue-based timeout algorithm for programs that use a large number of timeouts with the same value. + o New event_base_config option to disable the timeval cache entirely. + o Make EV_PERSIST timeouts more accurate: schedule the next event based on the scheduled time of the previous event, not based on the current time. + o Allow http.c to handle cases where getaddrinfo returns an IPv6 address. Patch from Ryan Phillips. + o Fix a problem with excessive memory allocation when using multiple event priorities. + o Default to using arc4random for DNS transaction IDs on systems that have it; from OpenBSD. + o Never check the environment when we're running setuid or setgid; from OpenBSD. + o Options passed to evdns_set_option() no longer need to end with a colon. + o Add an evutil_getaddrinfo() function to clone getaddrinfo on platforms that don't have it. + o Add an evdns_getaddrinfo() function to provide a nonblocking getaddrinfo using evdns, so programs can perform useful hostname lookup. + o Finally expose the IOCP-based bufferevent backend. It passes its unit tests, but probably still has some bugs remaining. Code by Nick Mathewson and Christopher Davis. + o Numerous other bugfixes. + o On FreeBSD and other OSes, connect can return ECONREFUSED immediately; instead of failing the function call, pretend with faileld in the callback. + o Fix a race condition in the pthreads test case; found by Nick Mathewson + o Remove most calls to event_err() in http and deal with memory errors instead + + + +Changes in 2.0.2-alpha (25 Jul 2009): + o Add a new flag to bufferevents to make all callbacks automatically deferred. + o Make evdns functionality locked, and automatically defer dns callbacks. + o Fix a possible free(NULL) when freeing an event_base with no signals. + o Add a flag to disable checking environment varibles when making an event_base + o Disallow setting less than 1 priority. + o Fix a bug when removing a timeout from the heap. [Patch from Marko Kreen] + o Use signal.h, not sys/signal.h. [Patch from mmadia] + o Try harder to build with certain older c99 compilers. + o Make sure that an event_config's flags field is always initialized to 0. [Bug report from Victor Goya] + o Avoid data corruption when reading data entirely into the second-to-last chain of an evbuffer. [Bug report from Victor Goya] + o Make sendfile work on FreeBSD + o Do not use vararg macros for accessing evrpc structures; this is not backwards compatible, but we did not promise any backwards compatibility for the rpc code. + o Actually define the event_config_set_flag() function. + o Try harder to compile with Visual C++. + o Move event_set() and its allies to event2/event_compat.h where they belong. + o Remove the event_gotsig code, which has long been deprecated and unused. + o Add an event_get_base() function to return the base assigned to an event. + o New function to automate connecting on a socket-based bufferevent. + o New functions to automate listening for incoming TCP connections. + o Do case-insensitive checks with a locale-independent comparison function. + o Rename the evbuffercb and everrorcb callbacks to bufferevent_data_cb and bufferevent_event_cb respectively. The old names are available in bufferevent_compat.h. + o Rename the EVBUFFER_* codes used by bufferevent event callbacks to BEV_EVENT_*, to avoid namespace collision with evbuffer flags. The old names are available in bufferevent_compat.h. + o Move the EVBUFFER_INPUT and EVBUFFER_OUTPUT macros to bufferevent_compat.h + o Add a bufferevent_getfd() function to mirror bufferevent_setfd() + o Make bufferevent_setfd() return an error code if the operation is not successful. + o Shave 22 bytes off struct event on 32-bit platforms by shrinking and re-ordering fields. The savings on 64-bit platforms is likely higher. + o Cap the maximum number of priorities at 256. + o Change the semantics of evbuffer_cb_set_flags() to be set-flag only; add a new evbuffer_cb_clear_flags() to remove set flags. + o Change the interface of evbuffer_add_reference so that the cleanup callback gets more information + o Revise the new evbuffer_reserve_space/evbuffer_commit_space() interfaces so that you can use them without causing extraneous copies or leaving gaps in the evbuffer. + o Add a new evbuffer_peek() interface to inspect data in an evbuffer without removing it. + o Fix a deadlock when suspending reads in a bufferevent due to a full buffer. (Spotted by Joachim Bauch.) + o Fix a memory error when freeing a thread-enabled event base with registered events. (Spotted by Joachim Bauch.) + o Try to contain degree of failure when running on a win32 version so heavily firewalled that we can't fake a socketpair. + o Activate fd events in a pseudorandom order with O(N) backends, so that we don't systematically favor low fds (select) or earlier-added fds (poll, win32). + o Replace some read()/write() instances with send()/recv() to work properly on win32. + o Set truncated flag correctly in evdns server replies. + o Raise RpcGenError in event_rpcgen.py; from jmanison and Zack Weinberg + o Fix preamble of rpcgen-generated files to rely on event2 includes; based on work by jmansion; patch from Zack Weinberg. + o Allow specifying the output filename for rpcgen; based on work by jmansion; patch from Zack Weinberg. + o Allow C identifiers as struct names; allow multiple comments in .rpc files; from Zack Weinberg + o Mitigate a race condition when using socket bufferevents in multiple threads. + o Use AC_SEARCH_LIBS, not AC_CHECK_LIB to avoid needless library use. + o Do not allow event_del(ev) to return while that event's callback is executing in another thread. This fixes a nasty race condition. + o event_get_supported_methods() now lists methods that have been disabled with the EVENT_NO* environment options. + o Rename encode_int[64] to evtag_encode_int[64] to avoid polluting the global namespace. The old method names are still available as macros in event2/tag_compat.h. + + + +Changes in 2.0.1-alpha (17 Apr 2009): + o free minheap on event_base_free(); from Christopher Layne + o debug cleanups in signal.c; from Christopher Layne + o provide event_base_new() that does not set the current_base global + o bufferevent_write now uses a const source argument; report from Charles Kerr + o improve documentation on event_base_loopexit; patch from Scott Lamb + o New function, event_{base_}loopbreak. Like event_loopexit, it makes an event loop stop executing and return. Unlike event_loopexit, it keeps subsequent pending events from getting executed. Patch from Scott Lamb + o Check return value of event_add in signal.c + o provide event_reinit() to reintialize an event_base after fork + o New function event_set_mem_functinons. It allows the user to give libevent replacement functions to use for memory management in place of malloc(), free(), etc. This should be generally useful for memory instrumentation, specialized allocators, and so on. + o The kqueue implementation now catches signals that are raised after event_add() is called but before the event_loop() call. This makes it match the other implementations. + o The kqueue implementation now restores original signal handlers correctly when its signal events are removed. + o Check return value of event_add in signal.c + o Add a more powerful evbuffer_readln as a replacement for evbuffer_readline. The new function handles more newline styles, and is more useful with buffers that may contain a nul characters. + o Do not mangle socket handles on 64-bit windows. + o The configure script now takes an --enable-gcc-warnigns option that turns on many optional gcc warnings. (Nick has been building with these for a while, but they might be useful to other developers.) + o move EV_PERSIST handling out of the event backends + o small improvements to evhttp documentation + o always generate Date and Content-Length headers for HTTP/1.1 replies + o set the correct event base for HTTP close events + o When building with GCC, use the "format" attribute to verify type correctness of calls to printf-like functions. + o Rewrite win32.c backend to be O(n lg n) rather than O(n^2). + o Removed obsoleted recalc code + o support for 32-bit tag numbers in rpc structures; this is wire compatible, but changes the API slightly. + o pull setters/getters out of RPC structures into a base class to which we just need to store a pointer; this reduces the memory footprint of these structures. + o prefix {encode,decode}_tag functions with evtag to avoid collisions + o fix a bug with event_rpcgen for integers + o Correctly handle DNS replies with no answers set (Fixes bug 1846282) + o add -Wstrict-aliasing to warnings and more cleanup + o removed linger from http server socket; reported by Ilya Martynov + o event_rpcgen now allows creating integer arrays + o support string arrays in event_rpcgen + o change evrpc hooking to allow pausing of RPCs; this will make it possible for the hook to do some meaning ful work; this is not backwards compatible. + o allow an http request callback to take ownership of a request structure + o allow association of meta data with RPC requests for hook processing + o associate more context for hooks to query such as the connection object + o remove pending timeouts on event_base_free() + o also check EAGAIN for Solaris' event ports; from W.C.A. Wijngaards + o devpoll and evport need reinit; tested by W.C.A Wijngaards + o event_base_get_method; from Springande Ulv + o Send CRLF after each chunk in HTTP output, for compliance with RFC2626. Patch from "propanbutan". Fixes bug 1894184. + o Add a int64_t parsing function, with unit tests, so we can apply Scott Lamb's fix to allow large HTTP values. + o Use a 64-bit field to hold HTTP content-lengths. Patch from Scott Lamb. + o Allow regression code to build even without Python installed + o remove NDEBUG ifdefs from evdns.c + o detect integer types properly on platforms without stdint.h + o udpate documentation of event_loop and event_base_loop; from Tani Hosokawa. + o simplify evbuffer by removing orig_buffer + o do not insert event into list when evsel->add fails + o add support for PUT/DELETE requests; from Josh Rotenberg + o introduce evhttp_accept_socket() to accept from an already created socket + o include Content-Length in reply for HTTP/1.0 requests with keep-alive + o increase listen queue for http sockets to 128; if that is not enough the evhttp_accpet_socket() api can be used with a prepared socket. + o Patch from Tani Hosokawa: make some functions in http.c threadsafe. + o test support for PUT/DELETE requests; from Josh Rotenberg + o rewrite of the evbuffer code to reduce memory copies + o Some older Solaris versions demand that _REENTRANT be defined to get strtok_r(); do so. + o Do not free the kqop file descriptor in other processes, also allow it to be 0; from Andrei Nigmatulin + o Provide OpenSSL style support for multiple threads accessing the same event_base + o make event_rpcgen.py generate code include event-config.h; reported by Sam Banks. + o switch thread support so that locks get allocated as they are needed. + o make event methods static so that they are not exported; from Andrei Nigmatulin + o make RPC replies use application/octet-stream as mime type + o do not delete uninitialized timeout event in evdns + o Correct the documentation on buffer printf functions. + o Don't warn on unimplemented epoll_create(): this isn't a problem, just a reason to fall back to poll or select. + o Correctly handle timeouts larger than 35 minutes on Linux with epoll.c. This is probably a kernel defect, but we'll have to support old kernels anyway even if it gets fixed. + o Make name_from_addr() threadsafe in http.c + o Add new thread-safe interfaces to evdns functions. + o Make all event_tagging interfaces threadsafe. + o Rename internal memory management functions. + o New functions (event_assign, event_new, event_free) for use by apps that want to be safely threadsafe, or want to remain ignorant of the contents of struct event. + o introduce bufferevent_read_buffer; allows reading without memory copy. + o expose bufferevent_setwatermark via header files and fix high watermark on read + o fix a bug in buffrevent read water marks and add a test for them + o fix a bug in which bufferevent_write_buffer would not schedule a write event + o provide bufferevent_input and bufferevent_output without requiring knowledge of the structure + o introduce bufferevent_setcb and bufferevent_setfd to allow better manipulation of bufferevents + o convert evhttp_connection to use bufferevents. + o use libevent's internal timercmp on all platforms, to avoid bugs on old platforms where timercmp(a,b,<=) is buggy. + o Remove the never-exported, never-used evhttp_hostportfile function. + o Support input/output filters for bufferevents; somewhat similar to libio's model. This will allow us to implement SSL, compression, etc, transparently to users of bufferevents such as the http layer. + o allow connections to be removed from an rpc pool + o add new evtimer_assign, signal_assign, evtimer_new, and signal_new functions to manipulate timer and signal events, analagous to the now-recommended event_assign and event_new + o switch internal uses of event_set over to use event_assign. + o introduce evbuffer_contiguous_space() api that tells a user how much data is available in the first buffer chain + o introduce evbuffer_reserve_space() and evbuffer_commit_space() to make processing in filters more efficient. + o reduce system calls for getting current time by caching it. + o separate signal events from io events; making the code less complex. + o support for periodic timeouts + o support for virtual HTTP hosts. + o turn event_initialized() into a function, and add function equivalents to EVENT_SIGNAL and EVENT_FD so that people don't need to include event_struct.h + o Build test directory correctly with CPPFLAGS set. + o Provide an API for retrieving the supported event mechanisms. + o event_base_new_with_config() and corresponding config APIs. + o migrate the evhttp header to event2/ but accessors are still missing. + o deprecate timeout_* event functions by moving them to event_compat.h + o Move windows gettimeofday replacement into a new evutil_gettimeofday(). + o Make configure script work on IRIX. + o provide a method for canceling ongoing http requests. + o Make vsnprintf() returns consistent on win32. + o Fix connection keep-alive behavior for HTTP/1.0 + o Fix use of freed memory in event_reinit; pointed out by Peter Postma + o constify struct timeval * where possible + o make event_get_supported_methods obey environment variables + o support for edge-triggered events on epoll and kqueue backends: patch from Valery Kholodkov + o support for selecting event backends by their features, and for querying the features of a backend. + o change failing behavior of event_base_new_with_config: if a config is provided and no backend is selected, return NULL instead of aborting. + o deliver partial data to request callbacks when chunked callback is set even if there is no chunking on the http level; allows cancelation of requests from within the chunked callback; from Scott Lamb. + o allow min_heap_erase to be called on removed members; from liusifan. + o Rename INPUT and OUTPUT to EVRPC_INPUT and EVRPC_OUTPUT. Retain INPUT/OUTPUT aliases on on-win32 platforms for backwards compatibility. + o Do not use SO_REUSEADDR when connecting + o Support 64-bit integers in RPC structs + o Correct handling of trailing headers in chunked replies; from Scott Lamb. + o Support multi-line HTTP headers; based on a patch from Moshe Litvin + o Reject negative Content-Length headers; anonymous bug report + o Detect CLOCK_MONOTONIC at runtime for evdns; anonymous bug report + o Various HTTP correctness fixes from Scott Lamb + o Fix a bug where deleting signals with the kqueue backend would cause subsequent adds to fail + o Support multiple events listening on the same signal; make signals regular events that go on the same event queue; problem report by Alexander Drozdov. + o Fix a problem with epoll() and reinit; problem report by Alexander Drozdov. + o Fix off-by-one errors in devpoll; from Ian Bell + o Make event_add not change any state if it fails; reported by Ian Bell. + o Fix a bug where headers arriving in multiple packets were not parsed; fix from Jiang Hong; test by me. + o Match the query in DNS replies to the query in the request; from Vsevolod Stakhov. + o Add new utility functions to correctly observe and log winsock errors. + o Do not remove Accept-Encoding header + o Clear the timer cache on entering the event loop; reported by Victor Chang + o Only bind the socket on connect when a local address has been provided; reported by Alejo Sanchez + o Allow setting of local port for evhttp connections to support millions of connections from a single system; from Richard Jones. + o Clear the timer cache when leaving the event loop; reported by Robin Haberkorn + o Fix a typo in setting the global event base; reported by lance. + o Set the 0x20 bit on outgoing alphabetic characters in DNS requests randomly, and insist on a match in replies. This helps resist DNS poisoning attacks. + o Make the http connection close detection work properly with bufferevents and fix a potential memory leak associated with it. + o Restructure the event backends so that they do not need to keep track of events themselves, as a side effect multiple events can use the same fd or signal. + o Add generic implementations for parsing and emiting IPv6 addresses on platforms that do not have inet_ntop and/or inet_pton. + o Allow DNS servers that have IPv6 addresses. + o Add an evbuffer_write_atmost() function to write a limited number of bytes to an fd. + o Refactor internal notify-main-thread logic to prefer eventfd to pipe, then pipe to socketpair, and only use socketpairs as a last resort. + o Try harder to pack all evbuffer reads into as few chains as possible, using readv/WSARecv as appropriate. + o New evthread_use_windows_threads() and evthread_use_pthreads() functions to set up the evthread callbacks with reasonable defaults. + o Change the semantics of timeouts in conjunction with EV_PERSIST; timeouts in that case will now repeat until deleted. + o sendfile, mmap and memory reference support for evbuffers. + o New evutil_make_listen_socket_reuseable() to abstract SO_REUSEADDR. + o New bind-to option to allow DNS clients to bind to an arbitrary port for outgoing requests. + o evbuffers can now be "frozen" to prevent operations at one or both ends. + o Bufferevents now notice external attempts to add data to an inbuf or remove it from an outbuf, and stop them. + o Fix parsing of queries where the encoded queries contained \r, \n or + + o Do not allow internal events to starve lower-priority events. + +Changes in 1.4.0: + o allow \r or \n individually to separate HTTP headers instead of the standard "\r\n"; from Charles Kerr. + o demote most http warnings to debug messages + o Fix Solaris compilation; from Magne Mahre + o Add a "Date" header to HTTP responses, as required by HTTP 1.1. + o Support specifying the local address of an evhttp_connection using set_local_address + o Fix a memory leak in which failed HTTP connections whould not free the request object + o Make adding of array members in event_rpcgen more efficient, but doubling memory allocation + o Fix a memory leak in the DNS server + o Fix compilation when DNS_USE_OPENSSL_FOR_ID is enabled + o Fix buffer size and string generation in evdns_resolve_reverse_ipv6(). + o Respond to nonstandard DNS queries with "NOTIMPL" rather than by ignoring them. + o In DNS responses, the CD flag should be preserved, not the TC flag. + o Fix http.c to compile properly with USE_DEBUG; from Christopher Layne + o Handle NULL timeouts correctly on Solaris; from Trond Norbye + o Recalculate pending events properly when reallocating event array on Solaris; from Trond Norbye + o Add Doxygen documentation to header files; from Mark Heily + o Add a evdns_set_transaction_id_fn() function to override the default + transaction ID generation code. + o Add an evutil module (with header evutil.h) to implement our standard cross-platform hacks, on the theory that somebody else would like to use them too. + o Fix signals implementation on windows. + o Fix http module on windows to close sockets properly. + o Make autogen.sh script run correctly on systems where /bin/sh isn't bash. (Patch from Trond Norbye, rewritten by Hagne Mahre and then Hannah Schroeter.) + o Skip calling gettime() in timeout_process if we are not in fact waiting for any events. (Patch from Trond Norbye) + o Make test subdirectory compile under mingw. + o Fix win32 buffer.c behavior so that it is correct for sockets (which do not like ReadFile and WriteFile). + o Make the test.sh script run unit tests for the evpoll method. + o Make the entire evdns.h header enclosed in "extern C" as appropriate. + o Fix implementation of strsep on platforms that lack it + o Fix implementation of getaddrinfo on platforms that lack it; mainly, this will make Windows http.c work better. Original patch by Lubomir Marinov. + o Fix evport implementation: port_disassociate called on unassociated events resulting in bogus errors; more efficient memory management; from Trond Norbye and Prakash Sangappa + o support for hooks on rpc input and output; can be used to implement rpc independent processing such as compression or authentication. + o use a min heap instead of a red-black tree for timeouts; as a result finding the min is a O(1) operation now; from Maxim Yegorushkin + o associate an event base with an rpc pool + o added two additional libraries: libevent_core and libevent_extra in addition to the regular libevent. libevent_core contains only the event core whereas libevent_extra contains dns, http and rpc support + o Begin using libtool's library versioning support correctly. If we don't mess up, this will more or less guarantee binaries linked against old versions of libevent continue working when we make changes to libevent that do not break backward compatibility. + o Fix evhttp.h compilation when TAILQ_ENTRY is not defined. + o Small code cleanups in epoll_dispatch(). + o Increase the maximum number of addresses read from a packet in evdns to 32. + o Remove support for the rtsig method: it hasn't compiled for a while, and nobody seems to miss it very much. Let us know if there's a good reason to put it back in. + o Rename the "class" field in evdns_server_request to dns_question_class, so that it won't break compilation under C++. Use a macro so that old code won't break. Mark the macro as deprecated. + o Fix DNS unit tests so that having a DNS server with broken IPv6 support is no longer cause for aborting the unit tests. + o Make event_base_free() succeed even if there are pending non-internal events on a base. This may still leak memory and fds, but at least it no longer crashes. + o Post-process the config.h file into a new, installed event-config.h file that we can install, and whose macros will be safe to include in header files. + o Remove the long-deprecated acconfig.h file. + o Do not require #include before #include . + o Add new evutil_timer* functions to wrap (or replace) the regular timeval manipulation functions. + o Fix many build issues when using the Microsoft C compiler. + o Remove a bash-ism in autogen.sh + o When calling event_del on a signal, restore the signal handler's previous value rather than setting it to SIG_DFL. Patch from Christopher Layne. + o Make the logic for active events work better with internal events; patch from Christopher Layne. + o We do not need to specially remove a timeout before calling event_del; patch from Christopher Layne. diff --git a/release/src/router/dnscrypt/src/libevent/Doxyfile b/release/src/router/dnscrypt/src/libevent/Doxyfile new file mode 100644 index 0000000000..5d3865e7e7 --- /dev/null +++ b/release/src/router/dnscrypt/src/libevent/Doxyfile @@ -0,0 +1,257 @@ +# Doxyfile 1.5.1 + +# This file describes the settings to be used by the documentation system +# doxygen (www.doxygen.org) for a project +# +# All text after a hash (#) is considered a comment and will be ignored +# The format is: +# TAG = value [value, ...] +# For lists items can also be appended using: +# TAG += value [value, ...] +# Values that contain spaces should be placed between quotes (" ") + +#--------------------------------------------------------------------------- +# Project related configuration options +#--------------------------------------------------------------------------- + +# The PROJECT_NAME tag is a single word (or a sequence of words surrounded +# by quotes) that should identify the project. + +PROJECT_NAME = libevent + +# Place all output under 'doxygen/' + +OUTPUT_DIRECTORY = doxygen/ + +# If the JAVADOC_AUTOBRIEF tag is set to YES then Doxygen +# will interpret the first line (until the first dot) of a JavaDoc-style +# comment as the brief description.

For the next couple of years, though, 'struct event' +# is user-visible, and so we can pretty much guarantee that release +# series won't be binary-compatible. +@INSTALL_LIBEVENT_TRUE@dist_bin_SCRIPTS = event_rpcgen.py +pkgconfigdir = $(libdir)/pkgconfig +LIBEVENT_PKGCONFIG = libevent.pc $(am__append_2) $(am__append_4) + +# These sources are conditionally added by configure.in or conditionally +# included from other files. +PLATFORM_DEPENDENT_SRC = \ + epoll_sub.c \ + arc4random.c + +EXTRA_DIST = \ + LICENSE \ + autogen.sh \ + event_rpcgen.py \ + libevent.pc.in \ + make-event-config.sed \ + Doxyfile \ + whatsnew-2.0.txt \ + Makefile.nmake test/Makefile.nmake \ + $(PLATFORM_DEPENDENT_SRC) + +LIBEVENT_LIBS_LA = libevent.la libevent_core.la libevent_extra.la \ + $(am__append_1) $(am__append_3) +@INSTALL_LIBEVENT_TRUE@lib_LTLIBRARIES = $(LIBEVENT_LIBS_LA) +@INSTALL_LIBEVENT_TRUE@pkgconfig_DATA = $(LIBEVENT_PKGCONFIG) +@INSTALL_LIBEVENT_FALSE@noinst_LTLIBRARIES = $(LIBEVENT_LIBS_LA) +SUBDIRS = . include sample test +@BUILD_WIN32_FALSE@SYS_LIBS = +@BUILD_WIN32_TRUE@SYS_LIBS = -lws2_32 -lshell32 -ladvapi32 +@BUILD_WIN32_FALSE@SYS_SRC = $(am__append_5) $(am__append_6) \ +@BUILD_WIN32_FALSE@ $(am__append_7) $(am__append_8) \ +@BUILD_WIN32_FALSE@ $(am__append_9) $(am__append_10) \ +@BUILD_WIN32_FALSE@ $(am__append_11) +@BUILD_WIN32_TRUE@SYS_SRC = win32select.c evthread_win32.c \ +@BUILD_WIN32_TRUE@ buffer_iocp.c event_iocp.c \ +@BUILD_WIN32_TRUE@ bufferevent_async.c $(am__append_5) \ +@BUILD_WIN32_TRUE@ $(am__append_6) $(am__append_7) \ +@BUILD_WIN32_TRUE@ $(am__append_8) $(am__append_9) \ +@BUILD_WIN32_TRUE@ $(am__append_10) $(am__append_11) +@BUILD_WIN32_FALSE@SYS_INCLUDES = +@BUILD_WIN32_TRUE@SYS_INCLUDES = -IWIN32-Code +BUILT_SOURCES = include/event2/event-config.h +CORE_SRC = event.c evthread.c buffer.c \ + bufferevent.c bufferevent_sock.c bufferevent_filter.c \ + bufferevent_pair.c listener.c bufferevent_ratelim.c \ + evmap.c log.c evutil.c evutil_rand.c strlcpy.c $(SYS_SRC) + +EXTRA_SRC = event_tagging.c http.c evdns.c evrpc.c +@BUILD_WITH_NO_UNDEFINED_FALSE@NO_UNDEFINED = +@BUILD_WITH_NO_UNDEFINED_TRUE@NO_UNDEFINED = -no-undefined +@BUILD_WITH_NO_UNDEFINED_FALSE@MAYBE_CORE = +@BUILD_WITH_NO_UNDEFINED_TRUE@MAYBE_CORE = libevent_core.la +GENERIC_LDFLAGS = -version-info $(VERSION_INFO) $(RELEASE) $(NO_UNDEFINED) +libevent_la_SOURCES = $(CORE_SRC) $(EXTRA_SRC) +libevent_la_LIBADD = @LTLIBOBJS@ $(SYS_LIBS) +libevent_la_LDFLAGS = $(GENERIC_LDFLAGS) +libevent_core_la_SOURCES = $(CORE_SRC) +libevent_core_la_LIBADD = @LTLIBOBJS@ $(SYS_LIBS) +libevent_core_la_LDFLAGS = $(GENERIC_LDFLAGS) +@PTHREADS_TRUE@libevent_pthreads_la_SOURCES = evthread_pthread.c +@PTHREADS_TRUE@libevent_pthreads_la_LIBADD = $(MAYBE_CORE) +@PTHREADS_TRUE@libevent_pthreads_la_LDFLAGS = $(GENERIC_LDFLAGS) +libevent_extra_la_SOURCES = $(EXTRA_SRC) +libevent_extra_la_LIBADD = $(MAYBE_CORE) $(SYS_LIBS) +libevent_extra_la_LDFLAGS = $(GENERIC_LDFLAGS) +@OPENSSL_TRUE@libevent_openssl_la_SOURCES = bufferevent_openssl.c +@OPENSSL_TRUE@libevent_openssl_la_LIBADD = $(MAYBE_CORE) $(OPENSSL_LIBS) +@OPENSSL_TRUE@libevent_openssl_la_LDFLAGS = $(GENERIC_LDFLAGS) +noinst_HEADERS = util-internal.h mm-internal.h ipv6-internal.h \ + evrpc-internal.h strlcpy-internal.h evbuffer-internal.h \ + bufferevent-internal.h http-internal.h event-internal.h \ + evthread-internal.h ht-internal.h defer-internal.h \ + minheap-internal.h log-internal.h evsignal-internal.h \ + evmap-internal.h changelist-internal.h iocp-internal.h \ + ratelim-internal.h WIN32-Code/event2/event-config.h \ + WIN32-Code/tree.h compat/sys/queue.h $(am__append_12) +EVENT1_HDRS = event.h evhttp.h evdns.h evrpc.h evutil.h +@INSTALL_LIBEVENT_TRUE@include_HEADERS = $(EVENT1_HDRS) +AM_CPPFLAGS = -I$(srcdir)/compat -I$(srcdir)/include -I./include $(SYS_INCLUDES) +DISTCLEANFILES = *~ libevent.pc ./include/event2/event-config.h +all: $(BUILT_SOURCES) config.h + $(MAKE) $(AM_MAKEFLAGS) all-recursive + +.SUFFIXES: +.SUFFIXES: .c .lo .o .obj +am--refresh: Makefile + @: +$(srcdir)/Makefile.in: $(srcdir)/Makefile.am $(am__configure_deps) + @for dep in $?;

As a + result, evbuffers can be used to pass data around without actually + incurring the overhead of copying the data. + + A new evbuffer can be allocated with evbuffer_new(), and can be + freed with evbuffer_free(). Most users will be using evbuffers via + the bufferevent interface. To access a bufferevent's evbuffers, use + bufferevent_get_input() and bufferevent_get_output(). + + There are several guidelines for using evbuffers. + + - if you already know how much data you are going to add as a result + of calling evbuffer_add() multiple times, it makes sense to use + evbuffer_expand() first to make sure that enough memory is allocated + before hand. + + - evbuffer_add_buffer() adds the contents of one buffer to the other + without incurring any unnecessary memory copies. + + - evbuffer_add() and evbuffer_add_buffer() do not mix very well: + if you use them, you will wind up with fragmented memory in your + buffer. + + - For high-performance code, you may want to avoid copying data into and out + of buffers. You can skip the copy step by using + evbuffer_reserve_space()/evbuffer_commit_space() when writing into a + buffer, and evbuffer_peek() when reading. + + In Libevent 2.0 and later, evbuffers are represented using a linked + list of memory chunks, with pointers to the first and last chunk in + the chain. + + As the contents of an evbuffer can be stored in multiple different + memory blocks, it cannot be accessed directly. Instead, evbuffer_pullup() + can be used to force a specified number of bytes to be contiguous. This + will cause memory reallocation and memory copies if the data is split + across multiple blocks.

The number of dots in the query name + * determines the order in which this list is used. + * + * Searching appears to be a single lookup from the point of view of the API, + * although many DNS queries may be generated from a single call to + * evdns_resolve. Searching can also drastically slow down the resolution + * of names. + * + * To disable searching: + * 1. Never set it up. If you never call evdns_resolv_conf_parse or + * evdns_search_add then no searching will occur. + * + * 2. If you do call evdns_resolv_conf_parse then don't pass + * DNS_OPTION_SEARCH (or DNS_OPTIONS_ALL, which implies it). + * + * 3. When calling evdns_resolve, pass the DNS_QUERY_NO_SEARCH flag. + * + * The order of searches depends on the number of dots in the name. If the + * number is greater than the ndots setting then the names is first tried + * globally. Otherwise each search domain is appended in turn. + * + * The ndots setting can either be set from a resolv.conf, or by calling + * evdns_search_ndots_set. + * + * For example, with ndots set to 1 (the default) and a search domain list of + * ["myhome.net"]: + * Query: www + * Order: www.myhome.net, www. + * + * Query: www.abc + * Order: www.abc., www.abc.myhome.net + * + * Internals: + * + * Requests are kept in two queues. The first is the inflight queue. In + * this queue requests have an allocated transaction id and nameserver. + * They will soon be transmitted if they haven't already been. + * + * The second is the waiting queue. The size of the inflight ring is + * limited and all other requests wait in waiting queue for space. This + * bounds the number of concurrent requests so that we don't flood the + * nameserver. Several algorithms require a full walk of the inflight + * queue and so bounding its size keeps thing going nicely under huge + * (many thousands of requests) loads. + * + * If a nameserver loses too many requests it is considered down and we + * try not to use it. After a while we send a probe to that nameserver + * (a lookup for google.com) and, if it replies, we consider it working + * again. If the nameserver fails a probe we wait longer to try again + * with the next probe. + */ + +#ifndef _EVENT2_DNS_H_ +#define _EVENT2_DNS_H_ + +#ifdef __cplusplus +extern "C" { +#endif + +/* For integer types. */ +#include + +/** Error codes 0-5 are as described in RFC 1035. */ +#define DNS_ERR_NONE 0 +/** The name server was unable to interpret the query */ +#define DNS_ERR_FORMAT 1 +/** The name server was unable to process this query due to a problem with the + * name server */ +#define DNS_ERR_SERVERFAILED 2 +/** The domain name does not exist */ +#define DNS_ERR_NOTEXIST 3 +/** The name server does not support the requested kind of query */ +#define DNS_ERR_NOTIMPL 4 +/** The name server refuses to reform the specified operation for policy + * reasons */ +#define DNS_ERR_REFUSED 5 +/** The reply was truncated or ill-formatted */ +#define DNS_ERR_TRUNCATED 65 +/** An unknown error occurred */ +#define DNS_ERR_UNKNOWN 66 +/** Communication with the server timed out */ +#define DNS_ERR_TIMEOUT 67 +/** The request was canceled because the DNS subsystem was shut down. */ +#define DNS_ERR_SHUTDOWN 68 +/** The request was canceled via a call to evdns_cancel_request */ +#define DNS_ERR_CANCEL 69 +/** There were no answers and no error condition in the DNS packet. + * This can happen when you ask for an address that exists, but a record + * type that doesn't. */ +#define DNS_ERR_NODATA 70 + +#define DNS_IPv4_A 1 +#define DNS_PTR 2 +#define DNS_IPv6_AAAA 3 +#define DNS_TXT 4 + +#define DNS_QUERY_NO_SEARCH 1 + +#define DNS_OPTION_SEARCH 1 +#define DNS_OPTION_NAMESERVERS 2 +#define DNS_OPTION_MISC 4 +#define DNS_OPTION_HOSTSFILE 8 +#define DNS_OPTIONS_ALL 15 + +/* Obsolete name for DNS_QUERY_NO_SEARCH */ +#define DNS_NO_SEARCH DNS_QUERY_NO_SEARCH + +struct txt_record { + char txt[255]; + size_t len; +}; + +/** + * The callback that contains the results from a lookup. + * - result is one of the DNS_ERR_* values (DNS_ERR_NONE for success) + * - type is either DNS_IPv4_A or DNS_PTR or DNS_IPv6_AAAA or DNS_TXT + * - count contains the number of addresses of form type + * - ttl is the number of seconds the resolution may be cached for. + * - addresses needs to be cast according to type.

The Libevent API provides a mechanism to execute a callback + function when a specific event occurs on a file descriptor or after a + timeout has been reached. Furthermore, Libevent also support callbacks due + to signals or regular timeouts. + + Libevent is meant to replace the event loop found in event driven network + servers. An application just needs to call event_dispatch() and then add or + remove events dynamically without having to change the event loop. + + + Currently, Libevent supports /dev/poll, kqueue(2), select(2), poll(2), + epoll(4), and evports. The internal event mechanism is completely + independent of the exposed event API, and a simple update of Libevent can + provide new functionality without having to redesign the applications. As a + result, Libevent allows for portable application development and provides + the most scalable event notification mechanism available on an operating + system. Libevent can also be used for multithreaded programs. Libevent + should compile on Linux, *BSD, Mac OS X, Solaris and, Windows. + + @section usage Standard usage + + Every program that uses Libevent must inclurde the + header, and pass the -levent flag to the linker. (You can instead link + -levent_core if you only want the main event and buffered IO-based code, + and don't want to link any protocol code.) + + @section setup Library setup + + Before you call any other Libevent functions, you need to set up the + library. If you're going to use Libevent from multiple threads in a + multithreaded application, you need to initialize thread support -- + typically by using evthread_use_pthreads() or + evthread_use_windows_threads(). See for more + information. + + This is also the point where you can replace Libevent's memory + management functions with event_set_mem_functions, and enable debug mode + with event_enable_debug_mode(). + + @section base Creating an event base + + Next, you need to create an event_base structure, using event_base_new() + or event_base_new_with_config(). The event_base is responsible for + keeping track of which events are "pending" (that is to say, being + watched to see if they become active) and which events are "active". + Every event is associated with a single event_base. + + @section event Event notification + + For each file descriptor that you wish to monitor, you must create an + event structure with event_new(). (You may also declare an event + structure and call event_assign() to initialize the members of the + structure.) To enable notification, you add the structure to the list + of monitored events by calling event_add(). The event structure must + remain allocated as long as it is active, so it should generally be + allocated on the heap. + + @section loop Dispaching evets. + + Finally, you call event_base_dispatch() to loop and dispatch events. + You can also use event_base_loop() for more fine-grained control. + + Currently, only one thread can be dispatching a given event_base at a + time. If you want to run events in multiple threads at once, you can + either have a single event_base whose events add work to a work queue, + or you can create multiple event_base objects. + + @section bufferevent I/O Buffers + + Libevent provides a buffered I/O abstraction on top of the regular event + callbacks. This abstraction is called a bufferevent. A bufferevent + provides input and output buffers that get filled and drained + automatically. The user of a buffered event no longer deals directly + with the I/O, but instead is reading from input and writing to output + buffers. + + Once initialized via bufferevent_socket_new(), the bufferevent structure + can be used repeatedly with bufferevent_enable() and + bufferevent_disable(). Instead of reading and writing directly to a + socket, you would call bufferevent_read() and bufferevent_write(). + + When read enabled the bufferevent will try to read from the file descriptor + and call the read callback. The write callback is executed whenever the + output buffer is drained below the write low watermark, which is 0 by + default. + + See for more information. + + @section timers Timers + + Libevent can also be used to create timers that invoke a callback after a + certain amount of time has expired. The evtimer_new() function returns + an event struct to use as a timer. To activate the timer, call + evtimer_add(). Timers can be deactivated by calling evtimer_del(). + + @section evdns Asynchronous DNS resolution + + Libevent provides an asynchronous DNS resolver that should be used instead + of the standard DNS resolver functions. See the + functions for more detail. + + @section evhttp Event-driven HTTP servers + + Libevent provides a very simple event-driven HTTP server that can be + embedded in your program and used to service HTTP requests. + + To use this capability, you need to include the header in your + program. See that header for more information. + + @section evrpc A framework for RPC servers and clients + + Libevent provides a framework for creating RPC servers and clients.

If ACTION-IF-FOUND is not specified, the +# default action will define HAVE_PTHREAD. +# +# Please let the authors know if this macro fails on any platform, or +# if you have any other suggestions or comments. This macro was based +# on work by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) +# (with help from M. Frigo), as well as ac_pthread and hb_pthread +# macros posted by Alejandro Forero Cuervo to the autoconf macro +# repository.
