This file is free documentation; the Free Software Foundation gives unlimited permission to copy, distribute and modify it. 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. 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. 4. Type `make install' to install the programs and any data files and documentation. 5. 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. 6. Often, you can also type `make uninstall' to remove the installed files again. 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 `..'. 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. 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'. 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. 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'. Optional Features ================= 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. 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 bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /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 the options to `configure', and exit. `--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. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. opensmtpd-7.6.0p1/README.md100644 001750 001750 00000020163 14704245311 0010762# OpenSMTPD [![Version](https://img.shields.io/badge/Version-7.6.0p1-brihtgreen.svg)](https://github.com/OpenSMTPD/OpenSMTPD/releases/tag/7.6.0p1) [![Coverity Scan analysis](https://scan.coverity.com/projects/278/badge.svg)](https://scan.coverity.com/projects/opensmtpd-opensmtpd) [![Packaging status](https://repology.org/badge/tiny-repos/opensmtpd.svg)](https://repology.org/project/opensmtpd/versions) [![License: ISC](https://img.shields.io/badge/License-ISC-blue.svg)](https://www.isc.org/licenses/) > **Warning** > This repository may be out of date compared to [OpenBSD smtpd source code](https://cvsweb.openbsd.org/src/usr.sbin/smtpd/). Downstream package maintainers should be aware of this when backporting security fixes and other changes. OpenSMTPD is a FREE implementation of the server-side SMTP protocol as defined by [RFC 5321](https://tools.ietf.org/html/rfc5321), with some additional standard extensions. It allows ordinary machines to exchange e-mails with other systems speaking the SMTP protocol. OpenSMTPD runs on various [Unix](https://en.wikipedia.org/wiki/Unix) and Unix-like operating systems including: - Linux - [FreeBSD](https://www.freebsd.org) - [OpenBSD](https://www.openbsd.org) - [NetBSD](https://www.netbsd.org) - [DragonFlyBSD](https://www.dragonflybsd.org) - [macOS](https://en.wikipedia.org/wiki/MacOS) For more information: http://www.opensmtpd.org/portable.html If you are looking for a comprehensive manual on how to build your own mail server visit our [wiki](https://github.com/OpenSMTPD/OpenSMTPD/wiki). ## Get in touch If you want to stay up to day with most recent developments or chat about OpenSMTPD you can: - subscribe to our [mailing list](http://www.opensmtpd.org/list.html) - join the IRC channel: `#opensmtpd` @ [irc.libera.chat](https://libera.chat) - submit a bug report or a feature request here on [GitHub](https://github.com/OpenSMTPD/OpenSMTPD) - visit GitHub's [discussions page](https://github.com/OpenSMTPD/OpenSMTPD/discussions) ## Documentation The manual pages are available [online](https://www.opensmtpd.org/manual.html), which you are encouraged to contribute to. ## Install via package manager Many distributions already provide a packaged version of opensmtpd. All you need to do is install it via your package manager. > **Warning** Some distributions might ship old versions of OpenSMTPD, and some distributions may selectively backport security fixes and other code changes. ### Debian/Ubuntu sudo apt install opensmtpd ### Archlinux Has a [dedicated wiki page](https://wiki.archlinux.org/index.php/OpenSMTPD#Installation) ### Alpine Linux apk install opensmtpd ### Fedora yum install opensmtpd ### macOS OpenSMTPD is available from [MacPorts](https://www.macports.org): port install opensmtpd ## Install via container Container images available at [this repo's packages page.](https://github.com/orgs/OpenSMTPD/packages) ## Install from source ### Install dependencies OpenSMTPD relies on: - [pkgconf](https://github.com/pkgconf/pkgconf) or [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/) - [libevent](http://libevent.org/) - [libressl](https://www.libressl.org/) or [OpenSSL](https://www.openssl.org/) When not building from a release tarball (e.g. from the git repository), the following dependencies are needed too: - [autoconf](http://www.gnu.org/software/autoconf/) - [automake](http://www.gnu.org/software/automake/) - [bison](http://www.gnu.org/software/bison/) or [byacc](http://invisible-island.net/byacc/byacc.html) - [libtool](http://www.gnu.org/software/libtool/) By default OpenSMTPD expects latest versions of all dependencies unless noted otherwise. Note that some distributions have different packages for a same library, you should always use the `-dev` or `-devel` package (for example, `libevent-dev` or `libevent-devel`) if you're going to build OpenSMTPD yourself. ### Get the source code Clone from github: git clone https://github.com/OpenSMTPD/OpenSMTPD.git [Download tarball](https://github.com/OpenSMTPD/OpenSMTPD/archive/7.6.0p1.tar.gz) Latest release can always be found [here](https://github.com/OpenSMTPD/OpenSMTPD/releases/latest) ### Compile cd opensmtpd* ./bootstrap # Only if you build from git sources ./configure make sudo make install #### Special notes for macOS Please launch configure with special directive about libevent directory: ./configure --with-libevent=/opt/local Though macOS includes a copy of bison in the bases system, you will need to install a more recent version from, e.g., MacPorts. ### Install sudo make install ### Setup historical interface OpenSMTPD provides a single utility `smtpctl` to control the daemon and the local submission subsystem. To accommodate systems that require historical interfaces such as `sendmail`, `newaliases` or `makemap`, the `smtpctl` utility can operate in compatibility mode if called with the historical name. On mailwrapper-enabled systems, this is achieved by editing `/etc/mailer.conf` and adding the following lines: sendmail /usr/sbin/smtpctl send-mail /usr/sbin/smtpctl mailq /usr/sbin/smtpctl makemap /usr/sbin/smtpctl newaliases /usr/sbin/smtpctl Whereas on systems that don't provide mailwrapper, it can be achieved by setting the appropriate symbolic links: ln -s /usr/sbin/smtpctl sendmail ln -s /usr/sbin/smtpctl send-mail ln -s /usr/sbin/smtpctl mailq ln -s /usr/sbin/smtpctl makemap ln -s /usr/sbin/smtpctl newaliases The OpenSMTPD project leaves it up to the package maintainers to setup the links in their packages as it is very hard for us to accommodate all systems with the preferred method in a clean way. ### Configure `/etc/smtpd.conf` Please have a look at the complete format description of `smtpd.conf` [configuration file](https://man.openbsd.org/smtpd.conf) ### Add OpenSMTPD users To operate, OpenSMTPD requires at least one user, by default `_smtpd`; and preferably two users, by default `_smtpd` and `_smtpq`. Using two users instead of one will increase security by a large factor so... if you want to voluntarily reduce security or you have absolute more faith in our code than we do, by all means use one. The instructions below assume the default users however, the configure script allows overriding these using the options: `--with-user-smtpd`, `--with-user-queue`, and `--with-group-queue`. #### NetBSD, Linux (Debian, Arch Linux, ...) mkdir /var/empty useradd -c "SMTP Daemon" -d /var/empty -s /sbin/nologin _smtpd useradd -c "SMTPD Queue" -d /var/empty -s /sbin/nologin _smtpq #### DragonFlyBSD, FreeBSD pw useradd _smtpd -c "SMTP Daemon" -d /var/empty -s /sbin/nologin pw useradd _smtpq -c "SMTPD Queue" -d /var/empty -s /sbin/nologin #### macOS First we need a group with an unused GID below `500`, list the current ones used: /usr/bin/dscl . -list /Groups PrimaryGroupID | sort -n -k2,2 Add a group - here we have picked `444`: /usr/bin/sudo /usr/bin/dscl . -create /Groups/_smtpd PrimaryGroupID 444 Then the user.

Helps with use cases like LDAP or custom auth. - Implement report responses for proc-filters too. - Changed the table protocol to a simpler text-based one. Existing proc tables needs to be updated since old ones won't work. The new protocol is documented in smtpd-tables(7). - Fixed the parsing of IPv6 addresses in file-backed table(5) - Document expected MDA behavior and the environment set by OpenSMTPD. - Set ORIGINAL_RECIPIENT in the environment of MDA scripts for compatibility with postfix. - Updated the bundled libtls. # Release 7.5.0p0 (2024-04-10) - Added support for RFC 7505 "Null MX" handling and treat an MX of "localhost" as it were a "Null MX". - Allow inline tables and filter listings in smtpd.conf(5) to span over multiple lines. - Enabled DSN for the implicit socket too. - Added the `no-dsn' option for listen on socket too. - Reject headers that start with a space or a tab. - Fixed parsing of the ORCPT parameter. - Fixed table lookups of IPv6 addresses. - Fixed handling of escape characters in To, From and Cc headers. - Run LMTP deliveries as the recipient user again. - Disallow custom commands and file reading in root's .forward file. - Do not process other users .forward files when an alternate delivery user is provided in a dispatcher. - Unify the table(5) parser used in smtpd(8) and makemap(8). - Allow to use table(5) mappings on various match constraints. Portability fixes: - re-add ASR_IPV4_BEFORE_IPV6 compile-time knob to prefer connecting to IPv6 instead of IPv4. - update asr(3) and imsg with OpenBSD. - fixed rpath handling on NetBSD in the configure. # Release 7.4.0p1 (2023-11-16) - Fixed potential crash with LibreSSL versions prior 3.8 due to arc4random_buf() symbol clash. - Fixed manpage install path; reintroduced --with-mantype - Fixed typo in the configure help string: it's --without-libbsd - Fixed a couple of issues on MacOS: - Fixed typo that resulted in the re-declaration of strlcpy() and strlcat() - Cast suseconds_t to long for *printf - Fixed res_hnok() and b64_{pton,ntop}() discovery # Release 7.4.0p0 (2023-10-25) - Avoid truncation of filtered data lines. Lines in the email body passed through a filter were truncated to roughly LINE_MAX bytes. - Allow arguments on NOOP. - Swap link-auth filter arguments and bump filter protocol version. It was ambiguous in the case the user name would contain a '|' character. - Add Message-ID as needed for messages received on the submission port. This was dropped during the incoming message parser refactor in 2018. - Drop ENGINE support. - Updated the bundled copy of libtls. This includes the removal of the support for TLS v1.0 and 1.1 as they were "MUST NOT use" for more than two years already. The neverending cleanup of the -portable layer continued. This includes the complete rework of some parts: - Rework of the configure script: + use AC_SYSTEM_EXTENSIONS + better checks for libraries using AC_SEARCH_LIBS + dropped some useless and/or redundant checks + better checks for functions, shouldn't yield false-positives + various simplification to the -portable layer thanks to these changes - Simplified the `bootstrap` script. # Release 7.3.0p2 (2023-09-20) - avoid potential use of uninitialized in ASN1_time_parse - backport ENGINE removal fix the build with newer LibreSSL # Release 7.3.0p1 (2023-06-30) - add missing include of stdio.h for fparseln(3) on FreeBSD - fix a typo in the configure - use fatal() instead of err(3) in xclosefrom() - don't add "-lcrypto -lssl" thrice - fix the build of the bundled libtls with LibreSSL - force the use of the bundled libtls and libasr - append, not prepend, to LIBS during automatic configuration - do not add -L/usr/local/lib or -L/usr/lib, nor -I/usr/local/include or -I/usr/include as consequence of missing --with-libevent - optionally link libbsd-ctor too # Release 7.3.0p0 (2023-06-17) Includes the following security fixes: - OpenBSD 7.2 errata 20 "smtpd(8) could abort due to a connection from a local, scoped ipv6 address" - OpenBSD 7.2 errata 22 "Out of bounds accesses in libc resolver" ## Configuration changes - The certificate to use is now selected by looking at the names found in the certificates themselves rather than the `pki` name. The set of certificates for a TLS listener must be defined explicitly by using the `pki` listener option multiple times. ## Synced with OpenBSD 7.3 - OpenBSD 6.8: * Run LMTP deliveries as the smtpd user instead of the recipient user. - OpenBSD 6.9: * Introduced smtp(1) `-a` to perform authentication before sending a message. * Fixed a memory leak in smtpd(8) resolver. * Prevented a crash due to premature release of resources by the smtpd(8) filter state machine. * Switch to libtls internally. * Change the way SNI works in smtpd.conf(5). TLS listeners may be configured with multiple certificates. The matching is based on the names included in the certificates. * Allow to specify TLS protocols and ciphers per listener and relay action. - OpenBSD 7.0: * Fixed incorrect status code for expired mails resulting in misleading bounce report in smtpd(8). * Added TLS options `cafile=(path)`, `nosni`, `noverify` and `servername=(name)` to smtp(1). * Allowed specification of TLS ciphers and protocols in smtp(1). - OpenBSD 7.1: * Stop verifying the cert or CA for a relay using opportunistic TLS. * Enabled TLS verify by default for outbound "smtps://" and "smtp+tls://", restoring documented smtpd(8) behavior. - OpenBSD 7.3: * Prevented smtpd(8) abort due to a connection from a local, scoped ipv6 address. ## Portable layer changes - libbsd and libtls are now optionally used if found. + Added `--with-libbsd`/`--without-libbsd` configure flag to enable linking to libbsd-overlay. + Added `--with-bundled-libtls` to force the usage of the bundled libtls. LibreTLS 3.7.0 (last version at the time of writing) and previous have a regression with OpenSSL 3+, so please use the bundled one. See the GitHub issue #1171 for more info. - Updated and cleanup of the OpenBSD compats. + Ported `res_randomid()` from OpenBSD. - The configure option `--with-path-CAfile` shouldn't be required anymore in most systems but it is retained since it could be useful in some configuration when using the bundled libtls. - Various minor portability fixes. # Release 6.8.0p2 (2020-12-24) - Fixed an uninitialized variable and potential stack overflow with IPv6 connections in smtpd(8). - Fixed smtpd(8) handling of user names containing "@" symbols. - Allowed handling of long lines in an smtpd(8) aliases table. - Removed mail.local(8) support for world-writable mail spools. # Release 6.7.1p1 (2020-05-21) - fixes a packaging issue causing asr.h to be installed in target system - fixes a possible crash in the MTA when establishing IPv6 connections # Release 6.7.0p1 (2020-05-21) ## New Features: - Allowed use of the smtpd(8) session username in built-in filters when available. - Introduced a `bypass` keyword to smtpd(8) so that built-in filters can bypass processing when a condition is met. - Allowed use of 'auth' as an origin in smtpd.conf(5). - Allowed use of mail-from and rctp-to as for and from parameters in smtpd.conf(5). ## Bug fixes: - Ensured legacy ssl(8) session ID is persistent during a client TLS session, fixing an issue using TLSv1.3 with smtp.mail.yahoo.com. - Fixed security vulnerabilities in smtpd(8). Corrected an out-of-bounds read in smtpd allowing an attacker to inject arbitrary commands into the envelope file to be executed as root, and ensured privilege revocation in smtpctl(8) to prevent arbitrary commands from being run with the _smtpq group. - Allowed mail.local(8) to be run as non-root, opening a pipe to lockspool(1) for file locking. - Fixed a security vulnerability in smtpd(8) which could lead to a privilege escalation on mbox deliveries and unprivileged code execution on lmtp deliveries. - Added support for CIDR in a: spf atoms in smtpd(8). - Fixed a possible crash in smtpd(8) when combining "from rdns" with nested virtual aliases under a particular configuration. ## Experimental Features: - Introduced smtp-out event reporting. - Improved filtering protocol. # Release 6.6.4p1 (2020-02-24) An out of bounds read in smtpd allows an attacker to inject arbitrary commands into the envelope file which are then executed as root. Separately, missing privilege revocation in smtpctl allows arbitrary commands to be run with the _smtpq group. # Release 6.6.3p1 (2020-02-10) Following the 6.6.2p1 release, various improvements were done in OpenBSD -current to mitigate the risk of similar bugs. This release back-ports them to the portable version of OpenSMTPD. # Release 6.6.2p1 (2020-01-28) This is CRITICAL security bugfix for [CVE-2020-7247](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-7247) Read more details in [this blog post](https://poolp.org/posts/2020-01-30/opensmtpd-advisory-dissected/) # Release 6.6.1p1 (2019-11-06) ## Changes in this release (since 6.6.0p1) This is a bugfix release. No new features were added. - Fixed crash on recipient expansion [#968](https://github.com/OpenSMTPD/OpenSMTPD/issues/968) - Fixed broken build with LibreSSL [#944](https://github.com/OpenSMTPD/OpenSMTPD/issues/944) - Fixed crash in `arc4random` caused by differences in OpenSSL vs LibreSSL compatibility layer plumbing [#958](https://github.com/OpenSMTPD/OpenSMTPD/issues/958) - Fixed issue where `from any` rules never matched by IPv6 sources [#969](https://github.com/OpenSMTPD/OpenSMTPD/issues/969) - Fixed crash that happened during mail relay on musl distros [#929](https://github.com/OpenSMTPD/OpenSMTPD/issues/929) - Added reference aliases file in `etc/aliases` - Fixed multiple compilation warnings [#965](https://github.com/OpenSMTPD/OpenSMTPD/issues/965) [#966](https://github.com/OpenSMTPD/OpenSMTPD/issues/966) [#967](https://github.com/OpenSMTPD/OpenSMTPD/issues/967) [#978](https://github.com/OpenSMTPD/OpenSMTPD/issues/978) [#977](https://github.com/OpenSMTPD/OpenSMTPD/issues/977) [#975](https://github.com/OpenSMTPD/OpenSMTPD/issues/975) # Release 6.6.0p1 (2019-10-26) ## Dependencies note: This release builds with LibreSSL > 3.0.2 or OpenSSL > 1.1.0. It's preferable to depend on LibreSSL as OpenSMTPD is written and tested with that dependency. In addition, the features parity is not respected, some features will not be available with OpenSSL, like ECDSA server-side certificates support in this release. OpenSSL library is considered as a best effort target TLS library and provided as a commodity, LibreSSL has become our target TLS library. ## Changes in this release (since 6.4.0): - various improvements to documentation and code - reverse dns session matching criteria added to smtpd.conf(5) - regex table lookup support added to smtpd.conf(5) - introduced support for ECDSA certificates with an ECDSA privsep engine - introduced builtin filters for basic filtering of incoming sessions - introduced option to deliver junk to a Junk folder in mail.maildir(8) - fixed the smtp(1) client so it uses correct default port for SMTPS - fixed an smtpd(8) crash on excessively large input - ensured mail rejected by an LMTP server stay queued ## Experimental features: - introduced a filters API to allow writing standalone filters for smtpd - introduced proxy-v2 support allowing smtpd to operate behind a proxy opensmtpd-7.6.0p1/LICENSE100644 001750 001750 00000035667 14426123625 0010533This file is part of the OpenSMTPD software.

It is reproduced here in a slightly edited form for convenience. A 65-character subset of US-ASCII is used, enabling 6 bits to be represented per printable character. (The extra 65th character, "=", is used to signify a special processing function.) The encoding process represents 24-bit groups of input bits as output strings of 4 encoded characters. Proceeding from left to right, a 24-bit input group is formed by concatenating 3 8-bit input groups. These 24 bits are then treated as 4 concatenated 6-bit groups, each of which is translated into a single digit in the base64 alphabet. Each 6-bit group is used as an index into an array of 64 printable characters. The character referenced by the index is placed in the output string. Table 1: The Base64 Alphabet Value Encoding Value Encoding Value Encoding Value Encoding 0 A 17 R 34 i 51 z 1 B 18 S 35 j 52 0 2 C 19 T 36 k 53 1 3 D 20 U 37 l 54 2 4 E 21 V 38 m 55 3 5 F 22 W 39 n 56 4 6 G 23 X 40 o 57 5 7 H 24 Y 41 p 58 6 8 I 25 Z 42 q 59 7 9 J 26 a 43 r 60 8 10 K 27 b 44 s 61 9 11 L 28 c 45 t 62 + 12 M 29 d 46 u 63 / 13 N 30 e 47 v 14 O 31 f 48 w (pad) = 15 P 32 g 49 x 16 Q 33 h 50 y Special processing is performed if fewer than 24 bits are available at the end of the data being encoded. A full encoding quantum is always completed at the end of a quantity. When fewer than 24 input bits are available in an input group, zero bits are added (on the right) to form an integral number of 6-bit groups. Padding at the end of the data is performed using the '=' character. Since all base64 input is an integral number of octets, only the ------------------------------------------------- following cases can arise: (1) the final quantum of encoding input is an integral multiple of 24 bits; here, the final unit of encoded output will be an integral multiple of 4 characters with no "=" padding, (2) the final quantum of encoding input is exactly 8 bits; here, the final unit of encoded output will be two characters followed by two "=" padding characters, or (3) the final quantum of encoding input is exactly 16 bits; here, the final unit of encoded output will be three characters followed by one "=" padding character. */ int b64_ntop(u_char const *src, size_t srclength, char *target, size_t targsize) { size_t datalength = 0; u_char input[3]; u_char output[4]; u_int i; while (2 < srclength) { input[0] = *src++; input[1] = *src++; input[2] = *src++; srclength -= 3; output[0] = input[0] >> 2; output[1] = ((input[0] & 0x03) << 4) + (input[1] >> 4); output[2] = ((input[1] & 0x0f) << 2) + (input[2] >> 6); output[3] = input[2] & 0x3f; if (datalength + 4 > targsize) return (-1); target[datalength++] = Base64[output[0]]; target[datalength++] = Base64[output[1]]; target[datalength++] = Base64[output[2]]; target[datalength++] = Base64[output[3]]; } /* Now we worry about padding. */ if (0 != srclength) { /* Get what's left. */ input[0] = input[1] = input[2] = '\0'; for (i = 0; i < srclength; i++) input[i] = *src++; output[0] = input[0] >> 2; output[1] = ((input[0] & 0x03) << 4) + (input[1] >> 4); output[2] = ((input[1] & 0x0f) << 2) + (input[2] >> 6); if (datalength + 4 > targsize) return (-1); target[datalength++] = Base64[output[0]]; target[datalength++] = Base64[output[1]]; if (srclength == 1) target[datalength++] = Pad64; else target[datalength++] = Base64[output[2]]; target[datalength++] = Pad64; } if (datalength >= targsize) return (-1); target[datalength] = '\0'; /* Returned value doesn't count \0. */ return (datalength); } /* skips all whitespace anywhere. converts characters, four at a time, starting at (or after) src from base - 64 numbers into three 8 bit bytes in the target area. it returns the number of data bytes stored at the target, or -1 on error. */ int b64_pton(char const *src, u_char *target, size_t targsize) { u_int tarindex, state; int ch; char *pos; state = 0; tarindex = 0; while ((ch = *src++) != '\0') { if (isspace(ch)) /* Skip whitespace anywhere. */ continue; if (ch == Pad64) break; pos = strchr(Base64, ch); if (pos == 0) /* A non-base64 character. */ return (-1); switch (state) { case 0: if (target) { if (tarindex >= targsize) return (-1); target[tarindex] = (pos - Base64) << 2; } state = 1; break; case 1: if (target) { if (tarindex + 1 >= targsize) return (-1); target[tarindex] |= (pos - Base64) >> 4; target[tarindex+1] = ((pos - Base64) & 0x0f) << 4 ; } tarindex++; state = 2; break; case 2: if (target) { if (tarindex + 1 >= targsize) return (-1); target[tarindex] |= (pos - Base64) >> 2; target[tarindex+1] = ((pos - Base64) & 0x03) << 6; } tarindex++; state = 3; break; case 3: if (target) { if (tarindex >= targsize) return (-1); target[tarindex] |= (pos - Base64); } tarindex++; state = 0; break; } } /* * We are done decoding Base-64 chars.

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 to 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. * * An XOR simple queue is used in the same way as a regular simple queue. * The difference is that the head structure also includes a "cookie" that * is XOR'd with the queue pointer (first, last or next) to generate the * real pointer value. * * For details on the use of these macros, see the queue(3) manual page. */ #if defined(QUEUE_MACRO_DEBUG) || (defined(_KERNEL) && defined(DIAGNOSTIC)) #define _Q_INVALID ((void *)-1) #define _Q_INVALIDATE(a) (a) = _Q_INVALID #else #define _Q_INVALIDATE(a) #endif /* * Singly-linked List definitions. */ #define SLIST_HEAD(name, type) \ struct name { \ struct type *slh_first;
