LuaInspect +includes its own copy of SciTE ExtMan +, and it's recommended to use +the included version because older versions might not work +properly. The files in the scite_lua subfolder are not strictly +necessary but are suggested. In particularly, scite_lua/luainspect.lua +allows ExtMan to find LuaInspect, and you will need to adjust this if +you move LuaInspect somewhere else relative to ExtMan. + +Dependencies: + Tested with SciTE version 2.12/2.20 (older versions might not work). + Requires http://lua-users.org/wiki/SciteExtMan (version included). + Note: ExtMan's ctagsdx.lua is recommended (allows "goto mark" + command to return to previous location following a "go to + definition" or "show all variable uses"). + +If you want to customize styles, add the contents of the +`light_styles` or `dark_styles` variable in the scite.lua file to a +SciTE properties file. + +== Configuring SciTE options == + +The following LuaInspect options can be configured in one of your +SciTE properties files: + + luainspect.update.always (0 or 1, default 1) + luainspect.delay.count (integer >= 1, default 5) + luainspect.annotate.all.locals (0 or 1, default 0) + luainspect.incremental.compilation (0 or 1, default 1) + luainspect.performance.tests (0 or 1, default 0) + luainspect.autocomplete.vars (0 or 1, default 0) + luainspect.autocomplete.syntax (0 or 1, default 0) + luainspect.path.append (string, default '') + luainspect.cpath.append (string, default '') + style.script_lua.scheme (string, '' or 'dark', default '') + +For details, see scite.lua. + +== Installation on VIM == + +See [2] for VIM editor support. + +== Preliminary support for luaanalyze style comments == + +To make all variables in scope match name 'ast$' be recognized by LuaInspect as a +table with field 'tag' of type string, add this to your code: + + --! context.apply_value('ast$', {tag=''}) + +The LuaInspect code itself uses this: + + --! require 'luainspect.typecheck' (context) + +== Design Notes == + +The font styles are intended to make the more dangerous +or questionable code stand out more. + +Local variables named '_' are ignored for purposes of unused/masking variable +reporting.

However, + this does mean that `getfenv(setfenv(f, t))` does not necessarily equal `t`, + which is incompatible with 5.1 code (a possible workaround would be [1]). + If `setfenv(f, {})` has an upvalue but no debug info, then this will raise + an error to prevent inadvertently executing potentially untrusted code in the + global environment. + + It is not normally considered good design to use `setfenv` and `getfenv` + (one reason they were removed in 5.2). When possible, consider replacing + these with `load` or `loadfile`, which are more restrictive and have native + implementations in 5.2. + + This module might be merged into a more general Lua 5.1/5.2 compatibility + library (e.g. a full reimplementation of Lua 5.2 `_G`). However, + `load/loadfile/getfenv/setfenv` perhaps are among the more cumbersome + functions not to have. + +INSTALLATION + + Download compat_env.lua: + + wget https://raw.github.com/gist/1654007/compat_env.lua + + Copy compat_env.lua into your LUA_PATH. + + Alternately, unpack, test, and install into LuaRocks: + + wget https://raw.github.com/gist/1422205/sourceunpack.lua + lua sourceunpack.lua compat_env.lua + (cd out && luarocks make) + +Related work + + http://lua-users.org/wiki/LuaVersionCompatibility + https://github.com/stevedonovan/Penlight/blob/master/lua/pl/utils.lua + - penlight implementations of getfenv/setfenv + http://lua-users.org/lists/lua-l/2010-06/msg00313.html + - initial getfenv/setfenv implementation + +References + + [1] http://lua-users.org/lists/lua-l/2010-06/msg00315.html + +Copyright + +(c) 2012 David Manura.

SciTE comes + with two built-in extensions. The multiplexing extension + (MultiplexExtension.cxx) allows you to plug-in more than one + extension. The Lua extension (LuaExtension.cxx) allows you to write + an extension with Lua scripts [2] rather than C++. Extensions in Lua + and C++ are fairly similar, but there is an "extension." + property that "is part of the generic SciTE Extension Interface but + is currently only used by the Lua Scripting Extension" [3] and that + allows an extension script to be applied only when the active buffer + is of a specific file type or directory (rather than globally). + These are called "Lua extension scripts" in contrast to (global) "Lua + startup scripts" ("ext.lua.startup.script" property). Handler + functions in the Lua extension scripts override global handlers in + the Lua startup script. Lua extension scripts supposedly provide a + standard and user-configurable way to apply extensions to specific + languages. + + Scintilla (not just SciTE) also supports lexers [4-5], which are + traditionally implemented in C++ (e.g. LexLua.cxx) and can be enabled + by the user for specific file types (rather than globally) via the + "lexer." property. Lexers can also be written in Lua + scripts [6] (i.e. OnStyle handler), via the Lua extension interface, + apparently either as Lua startup scripts or Lua extension scripts. + This differs from C++ lexers, which are not loaded via the extension + interface. Lexers are a Scintilla concept. Extensions are a SciTE + concept. + + LuaInspect is both a lexer and an extension. It does both + syntax highlighting (lexer) as well as event handling (extension) to + support intelligent behavior and analysis. LuaInspect also applies + only to Lua files (not globally) and it is implemented in Lua (not + C++). These characteristics entail that LuaInspect be a Lua extension + script. There is one exception though mentioned in the comments above + the scite.lua M.install() function in that certain initialization + actions are best handled early via a Lua startup script, so scite.lua + is called both as a startup script and extension script to do different + actions (although the mechanism is a bit awkward). You could have + LuaInspect operate entirely as a Lua startup script, but that + could interfere when editing non-Lua files. + + The fact that SciTE reloads extensions scripts on buffer swaps + is probably unnecessary but outside of our control. In any case, + overhead should be low. Note that the AST and token lists are cached + in the buffer object, which persists across buffer swaps, so the + really expensive parsing is avoided on buffer swaps. + + There is also SciTE ExtMan [7], which is normally (always?) loaded + as a Lua startup script. This provides various global utility + functions, as well as a mechanism to multiplex multiple Lua startup + scripts. LuaInspect does not use the latter, implementing instead + it's own install_handler mechanism, because LuaInspect is involved + in Lua extension scripts rather than Lua startup scripts. + install_handler is careful though to ensure that global handlers + in any Lua startup script (including ExtMan handlers) are still called. + + [1] http://www.scintilla.org/SciTEExtension.html + [2] http://www.scintilla.org/SciTELua.html + [3] http://www.scintilla.org/SciTEDoc.html + [4] http://www.scintilla.org/SciTELexer.html + [5] http://www.scintilla.org/ScintillaDoc.html#LexerObjects + [6] http://www.scintilla.org/ScriptLexer.html + [7] http://lua-users.org/wiki/SciteExtMan +]] + + +-- Whether to update the AST on every edit (true) or only when the selection +-- is moved to a different line (false). false can be more efficient for large files. +local UPDATE_ALWAYS = scite_GetProp('luainspect.update.always', '1') == '1' + +-- Styling will be delayed for DELAY_COUNT styling events following user typing. +-- However it will be immediately triggered on a cursor or line change. +-- 0 implies always style.

INSTALL.TXT + +Metalua 0.5 +=========== + +Metalua is a static metaprogramming system for Lua: a set of tools +that let you alter the compilation process in arbitrary, powerful and +maintainable ways. For the potential first-time users of such a +system, a descripition of these tools, as implemented by Metalua, +follows. + +Dynamic Parsers +--------------- + +One of the tools is the dynamic parser, which allows a source file to +change the grammar recognized by the parser, while it's being +parsed. Taken alone, this feature lets you make superficial syntax +tweaks on the language. The parser is based on a parser combinator +library called 'gg'; you should know the half dozen functions in gg +API to do advanced things: + +- There are a couple of very simple combinators like gg.list, + gg.sequence, qq.multisequence, gg.optkeyword etc. that offer a level + of expressiveness comparable to Yacc-like parsers. For instance, if + mlp.expr parses Lua expressions, gg.list{ mlp.expr } creates a + parser which handles lists of Lua expressions. + +- Since you can create all the combinators you can think of (they're + regular, higher-order functions), there also are combinators + specialized for typical language tasks. In Yacc-like systems, the + language definition quickly becomes unreadable, because all + non-native features have to be encoded in clumsy and brittle ways. + So if your parser won't natively let you specify infix operator + precedence and associativity easily, tough luck for you and your + code maintainers. With combinators OTOH, most of such useful + functions already exist, and you can write your owns without + rewriting the parser itself. For instance, adding an infix operator + would just look like: + + > mlp.expr.infix:add{ "xor", prec=40, assoc='left', builder=xor_builder } + + Moreover, combinators tend to produce usable error messages when fed + with syntactically incorrect inputs. It matters, because clearly + explaining why an invalid input is invalid is almost as important as + compiling a valid one, for a use=able compiler. + +Yacc-like systems might seem simpler to adopt than combinators, as +long as they're used on extremely simple problems. However, if you +either try to write something non trivial, or to write a simple macro +in a robust way, you'll need to use lots of messy tricks and hacks, +and spend much more time getting them (approximately) right than +that 1/2 hour required to master the regular features of gg. + + +Real meta-programming +--------------------- + +If you plan to go beyond trivial keyword-for-keyword syntax tweaks, +what will limit you is not syntax definition, but the ability to +manipulate source code conveniently: without the proper tools and +abstractions, even the simplest tasks will turn into a dirty hacks +fest, then either into a maintenance nightmare, or simply into +abandonware. Providing an empowering framework so that you don't get +stuck in such predicaments is Metalua's whole purpose. The central +concept is that programs prefer to manipulate code as trees, whereas +most developers prefer ASCII sources, so both representations must be +freely interchangeable. The make-or-break deal is then: + +- To easily let users see sources as trees, as sources, or as + combination thereof, and switch representations seamlessly. + +- To offer the proper libraries, that won't force you to reinvent a + square wheel, will take care of the most common pitfalls, won't + force you to resort to brittle hacks. + +On the former point, Lisps are at a huge advantage, their user syntax +already being trees. But languages with casual syntax can also offer +interchangeable tree/source views; Metalua has some quoting +{ ... } +and anti-quoting -{ ... } operators which let you switch between both +representations at will: internally it works on trees, but you always +have the option to see them as quoted sources. Metalua also supports a +slightly improved syntax for syntax trees, to improve their +readability. + +Library-wise, Metalua offers a set of syntax tree manipulation tools: + +- Structural pattern matching, a feature traditionally found in + compiler-writing specialized languages (and which has nothing to do + with string regular expressions BTW), which lets you express + advanced tree analysis operations in a compact, readable and + efficient way. If you have to work with advanced data structures + and you try it, you'll never go back. + +- The walker library allows you to perform transformations on big + portions of programs. It lets you easily express things like: + "replace all return statements which aren't in a nested function by + error statements", "rename all local variables and their instances + into unique fresh names", "list the variables which escape this + chunk's scope", "insert a type-checking instruction into every + assignments to variable X", etc. Most of non-trivial macros will + require some of those global code transformations, if you really want + them to behave correctly. + +- Macro hygiene, although not perfect yet in Metalua, is required if + you want to make macro writing reasonably usable (and contrary to a + popular belief, renaming local variables into fresh names only + address the easiest part of the hygiene issue; cf. changelog below + for more details). + +- The existing extensions are progressively refactored in more modular + ways, so that their features can be effectively reused in other + extensions. + + +Noteworthy changes from 0.4.1 to 0.5 +==================================== + +Simplification of the install and structure: + +- This release is included in Lua for Windows, so it now couldn't get simpler + for MS-Windows users! + +- Metalua is written in pure Lua again, thus making it platform-independant. + No more mandatory C libraries. Pluto interface might be back, as an option, + in a future version, but it's not worth the install trouble involved by + DLL dependencies. + +- Simpler build process, just run make.sh or make.bat depending on your OS. + +- Metalua libraries are now in a separate metalua/* package. This allows to + mix them with other Lua libraries, and to use them from plain Lua programs + if you FIXME + + +Other changes: + +- new option -S in metalua: prints sources re-generated from AST, after macro + expansion. + +- compatible with more Lua VMs: 64 bits numbers, integral numbers, big endians... + +- some new extensions: xloop, xmatch, improved match. + +- ASTs now keep track of the source extract that generated them (API is not + mature though, it will be changed and broken). + +- improved table printer: support of a plain-Lua mode, alternative indentation + mode for deeply-nested tables. + +- added a generic table serializer, which handles shared and recursive + sub-tables correctly. + +- gg API has been made slightly more flexible, as a first step towards a + comprehensive syntax support for gg grammar definition. Follow the gg-syntax + branch on github for ongoing work. + + +Noteworthy changes from 0.4 to 0.4.1 +==================================== + +- Proper reporting of runtime errors +- Interactive REPL loop +- Support for 64 bits architectures +- Update to Pluto 2.2 and Lua 5.1.3 +- Build for Visual Studio .NET + +Notworthy changes from 0.3 to 0.4 +================================= + +- A significantly bigger code base, mostly due to more libraries: + about 2.5KLoC for libs, 4KLoC for the compiler. However, this remains + tiny in today's desktop computers standards. You don't have to know + all of the system to do useful stuff with it, and since compiled + files are Lua 5.1 compatible, you can keep the "big" system on a + development platform, and keep a lightweight runtime for embedded or + otherwise underpowered targets. + + +- The compiler/interpreter front-end is completely rewritten. The new + frontend program, aptly named 'Metalua', supports proper passing of + arguments to programs, and is generally speaking much more user + friendly than the mlc from the previous version. + + +- Metalua source libraries are looked for in environmemt variable + LUA_MPATH, distinct from LUA_PATH. This way, in an application + that's part Lua part Metalua, you keep a natural access to the + native Lua compiler. + + By convention, Metalua source files should have extension .mlua. By + default, bytecode and plain lua files have higher precedence than + Metalua sources, which lets you easily precompile your libraries. + + +- Compilation of files are separated in different Lua Rings: this + prevents unwanted side-effects when several files are compiled + (This can be turned off, but shouldn't be IMO). + + +- Metalua features are accessible programmatically. Library + 'Metalua.runtime' loads only the libraries necessary to run an + already compiled file; 'Metalua.compile' loads everything useful at + compile-time. + + Transformation functions are available in a library 'mlc' that + contains all meaningful transformation functions in the form + 'mlc.destformat_of_sourceformat()', such as 'mlc.luacfile_of_ast()', + 'mlc.function_of_luastring()' etc. This library has been + significantly completed and rewritten (in Metalua) since v0.3. + + +- Helper libraries have been added. For now they're in the + distribution, at some point they should be luarocked in. These + include: + - Lua Rings and Pluto, duct-taped together into Springs, an improved + Rings that lets states exchange arbitrary data instead of just + scalars and strings. Since Pluto requires a (minor) patch to the + VM, it can be disabled. + - Lua bits for bytecode dumping. + - As always, very large amounts of code borrowed from Yueliang. + - As a commodity, I've also packaged Lua sources in. + + +- Extensions to Lua standard libraries: many more features in table + and the baselib, a couple of string features, and a package system + which correctly handles Metalua source files. + + +- Builds on Linux, OSX, Microsoft Visual Studio. Might build on mingw + (not tested recently, patches welcome). It's easily ported to all + systems with a full support for lua, and if possible dynamic + libraries. + + The MS-windows building is based on a dirty .bat script, because + that's pretty much the only thing you're sure to find on a win32 + computer. It uses Microsoft Visual Studio as a compiler (tested with + VC++ 6). + + Notice that parts of the compiler itself are now written in Metalua, + which means that its building now goes through a bootstrapping + stage. + + +- Structural pattern matching improvements: + - now also handles string regular expressions: 'someregexp'/pattern + will match if the tested term is a string accepted by the regexp, + and on success, the list of captures done by the regexp is matched + against pattern. + - Matching of multiple values has been optimized + - the default behavior when no case match is no to raise an error, + it's the most commonly expected case in practice. Trivial to + cancel with a final catch-all pattern. + - generated calls to type() are now hygienic (it's been the cause of + a puzzling bug report; again, hygiene is hard). + + +- AST grammar overhaul: + The whole point of being alpha is to fix APIs with a more relaxed + attitude towards backward compatibility. I think and hope it's the + last AST revision, so here is it: + - `Let{...} is now called `Set{...} + (Functional programmers would expect 'Let' to introduce an + immutable binding, and assignment isn't immutable in Lua) + - `Key{ key, value } in table literals is now written `Pair{ key, value } + (it contained a key *and* its associated value; besides, 'Pair' is + consistent with the name of the for-loop iterator) + - `Method{...} is now `Invoke{...} + (because it's a method invocation, not a method declaration) + - `One{...} is now `Paren{...} and is properly documented + (it's the node representing parentheses: it's necessary, since + parentheses are sometimes meaningful in Lua) + - Operator are simplified: `Op{ 'add', +{2}, +{2} } instead of + `Op{ `Add, +{2}, +{2} }. Operator names match the corresponding + metatable entries, without the leading double-underscore. + - The operators which haven't a metatable counterpart are + deprecated: 'ne', 'ge', 'gt'. + + +- Overhaul of the code walking library: + - the API has been simplified: the fancy predicates proved more + cumbersome to use than a bit of pattern matching in the visitors. + - binding identifiers are handled as a distinct AST class + - walk.id is scope-aware, handles free and bound variables in a + sensible way. + - the currified API proved useless and sometimes cumbersome, it's + been removed. + + +- Hygiene: I originally planned to release a full-featured hygienic + macro system with v0.4, but what exists remains a work in + progress. Lua is a Lisp-1, which means unhygienic macros are very + dangerous, and hygiene a la Scheme pretty much limits macro writing + to a term rewriting subset of the language, which would be crippling + to use. + + Note: inside hygiene, i.e. preventing macro code from capturing + variables in user code, is trivial to address through alpha + conversion, it's not the issue. The trickier part is outside + hygiene, when user's binders capture globals required by the + macro-generated code. That's the cause of pretty puzzling and hard + to find bugs. And the *really* tricky part, which is still an open + problem in Metalua, is when you have several levels of nesting + between user code and macro code. For now this case has to be + hygienized by hand. + + Note 2: Converge has a pretty powerful approach to hygienic macros + in a Lisp-1 language; for reasons that would be too long to expose + here, I don't think its approach would be the best suited to Metalua. + But I might well be proved wrong eventually. + + Note 3: Redittors must have read that Paul Graham has released Arc, + which is also a Lisp-1 with Common Lisp style macros; I expect this + to create a bit of buzz, out of which might emerge proper solutions + the macro hygiene problem. + + +- No more need to create custom syntax for macros when you don't want + to. Extension 'dollar' will let you declare macros in the dollar + table, as in +{block: function dollar.MYMACRO(a, b, c) ... end}, + and use it as $MYMACRO(1, 2, 3) in your code. + + With this extension, you can write macros without knowing anything + about the Metalua parser. Together with quasi-quotes and automatic + hygiene, this will probably be the closest we can go to "macros for + dummies" without creating an unmaintainable mess generator. + + Besides, it's consistent with my official position that focusing on + superficial syntax issues is counter-productive most of the time :) + + +- Lexers can be switched on the fly. This lets you change the set of + keywords temporarily, with the new gg.with_lexer() combinator. You + can also handle radically different syntaxes in a single file (think + multiple-languages systems such as LuaTeX, or programs+goo as PHP). + + +- Incorporation of the bug fixes reported to the mailing list and on + the blog. + + +- New samples and extensions, in various states of completion: + + * lists by comprehension, a la python/haskell. It includes lists + chunking, e.g. mylist[1 ... 3, 5 ... 7] + + * anaphoric macros for 'if' and 'while' statements: with this + extension, the condition of the 'if'/'while' is bound to variable + 'it' in the body; it lets you write things like: + + > while file:read '*l' do print(it) end. + + No runtime overhead when 'it' isn't used in the body. An anaphoric + variable should also be made accessible for functions, to let + easily write anonymous recursive functions. + + * Try ... catch ... finally extension. Syntax is less than ideal, + but the proper way to fix that is to refactor the match extension + to improve code reuse. There would be many other great ways to + leverage a refactored match extension, e.g. destructuring binds or + multiple dispatch methods. To be done in the next version. + + * with ... do extension: it uses try/finally to make sure that + resources will be properly closed. The only constraint on + resources is that they have to support a :close() releasing method. + For instance, he following code guarantees that file1 and file2 + will be closed, even if a return or an error occurs in the body. + + > with file1, file2 = io.open "f1.txt", io.open "f2.txt" do + > contents = file1:read'*a' .. file2:read ;*a' + > end + + * continue statement, logging facilities, ternary "?:" choice + operator, assignments as expressions, and a couple of similarly + tiny syntax sugar extensions. + + +You might expect in next versions +================================= +The next versions of Metalua will provide some of the following +improvements, in no particular order: better error reporting, +especially at runtime (there's a patch I've been too lazy to test +yet), support for 64 bits CPUs, better support for macro hygiene, more +samples and extensions, an adequate test suite, refactored libraries. + + +Credits +======= + +I'd like to thank the people who wrote the open source code which +makes Metalua run: the Lua team, the authors of Yueliang, Pluto, Lua +Rings, Bitlib; and the people whose bug reports, patches and +insightful discussions dramatically improved the global design, +including John Belmonte, Vyacheslav Egorov, David Manura, Olivier +Gournet, Eric Raible, Laurence Tratt, Alexander Gladysh, Ryan +Pusztai... diff --git a/builders/lua-inspect/metalualib/gg.lua b/builders/lua-inspect/metalualib/gg.lua new file mode 100644 index 000000000..26d93d955 --- /dev/null +++ b/builders/lua-inspect/metalualib/gg.lua @@ -0,0 +1,748 @@ +---------------------------------------------------------------------- +-- Metalua. +-- +-- Summary: parser generator.

Then build mosquitto, add a mosquitto user and set ownership for /var/log/mosquitto and /var/lib/mosquitto/ (default log and persistence locations). + +``` +make +sudo make install +sudo groupadd mosquitto +sudo useradd -s /sbin/nologin mosquitto -g mosquitto -d /var/lib/mosquitto +sudo mkdir -p /var/log/mosquitto/ /var/lib/mosquitto/ +sudo chown -R mosquitto:mosquitto /var/log/mosquitto/ +sudo chown -R mosquitto:mosquitto /var/lib/mosquitto/ +``` + +Finally, you may create a service for mosquitto. Create the file /etc/systemd/system/mosquitto.service with these annotations: + +``` +[Unit] +Description=Mosquitto MQTT v3.1/v5 server +Wants=network.target +Documentation=http://mosquitto.org/documentation/ + +[Service] +Type=simple +User=mosquitto +Group=mosquitto +ExecStart=/usr/local/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf +Restart=on-failure +SyslogIdentifier=Mosquitto + +[Install] +WantedBy=multi-user.target +``` + +If you are running another distro or need more details on building mosquitto, please check the offical mosquitto docs. + +#### Building the plugin + +Only Linux (tested in Debian, Ubuntu and Mint ùs) and MacOS are supported. + +Before attempting to build the plugin, make sure you have go installed on the system. +The minimum required Go version for the current release is 1.18. +To check which version (if any) of Go is installed on the system, simply run the following: + +``` +go version +``` + +If Go is not installed or the installed version is older than 1.18, please update it. +You can retrieve and install the latest version of Go from the official [Go download website](https://go.dev/dl/) which also have installation instructions. + +This will fetch the go dependecies and then build the `go-auth.so` shared object: + +``` +make +``` + +This assumes that `mosquitto.h`, `mosquitto_plugin.h` and `mosquitto_broker.h` are located at `/usr/include` or `/usr/local/include` +on MacOS or debian-based systems (and probably other linux systems too). + +On debian-based systems you can install the header files via apt (```apt install mosquitto-dev libmosquitto-dev```). They will be placed under `/usr/include`. + +On MacOS you can install the header files via homebrew (```brew install mosquitto```). MacOS on ARM hardware will place the header +files under `/opt/homebrew/include` and on x86_64 (Intel) hardware under `/usr/local/homebrew/include`. You have to either copy these headers under `/usr/local/include`, +create a symlink or configure `make` to include homebrew's include path too. + +You can also just download the header files at https://github.com/eclipse/mosquitto/tree/master/include (**change versions accordingly**) +and place them under `/usr/local/include`. + +If this doesn't work for your distribution or OS version, please check `Makefile` `CFLAGS` and `LDFLAGS` and adjust accordingly. +File an issue or open a PR if you wish to contribute correct flags for your system. + +#### Raspberry Pi + +**Important notice:** RPi support has been tested only until versions 1.4.x. +The introduction of new plugin functions in Mosquitto may result in some issue compiling versions 1.5.x and later. +Please reach me with any solutions you may find when resolving said issues. + +To build on a Raspberry Pi (tested with Pi 3 B), you'll need to have Go installed first. +You can install latest version (**last tested was 1.10.1, change it to suit your needs**) with something like this: + +``` +wget https://storage.googleapis.com/golang/go1.10.1.linux-armv6l.tar.gz +sudo tar -C /usr/local -xzf go1.10.1.linux-armv6l.tar.gz +``` + +Add Go to your path at .profile: + +` +export PATH=$PATH:/usr/local/go/bin:~/go/bin +` + +Source the file (`source ~/.profile`) and check Go was correctly installed (`go version`). + +Now get requirements and build as usual (just have some more patience). + +##### Openssl and websockets notes + +There seems to be missing packages in some Raspbian versions, so you should try to apt update before installing dependencies. Alternatively, you cand build openssl like this: + +``` +git clone git://git.openssl.org/openssl.git +cd openssl +./config +make +make test +sudo make install +``` + +For websockets support, you'll have to build libwebsockets, which needs cmake. So something like this should do the trick: + +``` +sudo apt-get install cmake +git clone https://github.com/warmcat/libwebsockets.git +cd libwebsockets +mkdir build +cd build +cmake .. +make +make install +``` + +### Configuration + +The plugin is configured in [Mosquitto's](https://mosquitto.org/) configuration file (typically `mosquitto.conf`). +You may define all options there, or include e.g. a `conf.d` dir for plugin configuration: + +``` +include_dir /etc/mosquitto/conf.d +``` + +Create some conf file (e.g., `go-auth.conf`) at your preferred location, e.g. `/etc/mosquitto/conf.d/`, and register the plugin's shared object path and desired backends with: + +``` +auth_plugin /etc/mosquitto/conf.d/go-auth.so + +auth_opt_backends files, postgres, jwt +``` + +Set all other plugin options below in the same file. + +#### Cache + +There are 2 types of caches supported: an in memory one using [go-cache](https://github.com/patrickmn/go-cache), or a Redis backed one. + +Set `cache` option to true to use a cache (defaults to false when missing) and `cache_type` to set the type of the cache. By default the plugin will use `go-cache` unless explicitly told to use Redis. +Set `cache_reset` to flush the cache on mosquitto startup (**hydrating `go-cache` on startup is not yet supported**). + +**Update v1.2:** +Set `cache_refresh` to refresh expiration each time a record is found in the cache (defaults to false). +Before v1.2 cache was always refreshed upon check. +In order to prevent security issues, where an attacker would frequently check on a topic to keep their granted status, +even when revoked in the underlying backend, this has been turned into an option that defaults to no refreshing. + +Finally, set expiration times in seconds for authentication (`auth`) and authorization (`acl`) caches: + +``` +auth_opt_cache true +auth_opt_cache_type redis +auth_opt_cache_reset true +auth_opt_cache_refresh true + +auth_opt_auth_cache_seconds 30 +auth_opt_acl_cache_seconds 30 +auth_opt_auth_jitter_seconds 3 +auth_opt_acl_jitter_seconds 3 +``` + +`auth_jitter_seconds` and `acl_jitter_seconds` options allow to randomize cache expiration time by a given offset +The value used for expiring a cache record would then be `cache_seconds` +/- `jitter_seconds`. With above values (30 seconds for cache and 3 seconds for jitter), effective expiration would yield any value between 27 and 33 seconds. +Setting a `jitter` value is useful to reduce lookups storms that could occur every `auth/acl_cache_seconds` if lots of clients connected at the same time, e.g. after a server restart when all clients may reconnect immediately creating lots of entries expiring at the same time. +You may omit or set jitter options to 0 to disable this feature. + +If `cache_reset` is set to false or omitted, cache won't be flushed upon service start. + +When using Redis, the following defaults will be used if no values are given. Also, these are the available options for cache: + +``` +auth_opt_cache_host localhost +auth_opt_cache_port 6379 +auth_opt_cache_password pwd +auth_opt_cache_db 3 +``` + +If you want to use a Redis cluster as your cache, you may omit previous Redis options and instead need to set `auth_opt_cache_mode` to `cluster` and provide the different addresses as a list of comma separated `host:port` strings with the `auth_opt_cache_addresses` options: + +``` +auth_opt_cache_mode cluster +auth_opt_cache_addresses host1:port1,host2:port2,host3:port3 +``` + +Notice that if `cache_mode` is not provided or isn't equal to `cluster`, cache will default to use a single instance with the common options. If instead the mode is set to `cluster` but no addresses are given, the plugin will default to not use a cache. + +#### Hashing + +There are 3 options for password hashing available: `PBKDF2` (default), `Bcrypt` and `Argon2ID`. Every backend that needs one -that's all but `grpc`, `http` and `custom`- gets a hasher and whether it uses specific options or general ones depends on the auth opts passed. + +Provided options define what hasher each backend will use: + +- If there are general hashing options available but no backend ones, then every backend will use those general ones for its hasher. +- If there are no options available in general and none for a given backend either, that backend will use defaults (see `hashing/hashing.go` for default values). +- If there are options for a given backend but no general ones, the backend will use its own hasher and any backend that doesn't register a hasher will use defaults. + +You may set the desired general hasher with this option, passing either `pbkdf2`, `bcrypt` or `argon2id` values. When not set, the option will default to `pbkdf2`. + +``` +auth_opt_hasher pbkdf2 + +``` + +Each hasher has specific options. Notice that when using the `pw` utility, these values must match those used to generate the password. + +##### PBKDF2 + +``` +auth_opt_hasher_salt_size 16 # salt bytes length +auth_opt_hasher_iterations 100000 # number of iterations +auth_opt_hasher_keylen 64 # key length +auth_opt_hasher_algorithm sha512 # hashing algorithm, either sha512 (default) or sha256 +auth_opt_hasher_salt_encoding # salt encoding, either base64 (default) or utf-8 +``` + +##### Bcrypt + +``` +auth_opt_hasher_cost 10 # key expansion iteration count +``` + +##### Argon2ID + +``` +auth_opt_hasher_salt_size 16 # salt bytes length +auth_opt_hasher_iterations 3 # number of iterations +auth_opt_hasher_keylen 64 # key length +auth_opt_hasher_memory 4096 # amount of memory (in kibibytes) to use +auth_opt_hasher_parallelism 2 # degree of parallelism (i.e. number of threads) +``` + +**These options may be defined for each backend that needs a hasher by prepending the backend's name to the option, e.g. for setting `argon2id` as `Postgres'` hasher**: + +``` +auth_opt_pg_hasher argon2id +auth_opt_pg_hasher_salt_size 16 # salt bytes length +auth_opt_pg_hasher_iterations 3 # number of iterations +auth_opt_pg_hasher_keylen 64 # key length +auth_opt_pg_hasher_memory 4096 # amount of memory (in kibibytes) to use +auth_opt_pg_hasher_parallelism # degree of parallelism (i.e. number of threads) +``` + +#### Logging + +You can set the log level with the `log_level` option. Valid values are: `debug`, `info`, `warn`, `error`, `fatal` and `panic`. If not set, default value is `info`. + +``` +auth_opt_log_level debug +``` + +Log destination may be set with `log_dest` option. Valid values are `stderr` (default), `stdout` and `file`. In the latter case the `log_file` option needs to be set, e.g.: + +``` +auth_opt_log_dest file +auth_opt_log_file /var/log/mosquitto/mosquitto.log +``` + +If `log_dest` or `log_file` are invalid, or if there's an error opening the file (e.g. no permissions), logging will default to `stderr`. + +**Do not, I repeat, do not set `log_level` to `debug` in production, it may leak sensitive information.** +**Reason? When debugging it's quite useful to log actual passwords, hashes, etc. to check which backend or hasher is failing to do its job.** +**This should be used only when debugging locally, I can't stress enough how log level should never, ever be set to `debug` in production.** + +**You've been warned.** + +#### Retry + +By default, if backend had an error (and no other backend granted access), an error is returned to Mosquitto. + +It's possible to enable retry, which will immediately retry all configured backends. This could be useful if the +backend may be behind a load-balancer (like HTTP backend) and one instance may fail: + +``` +auth_opt_retry_count 2 +``` + +The above example will do up to 2 retries (3 calls in total considering the original one) if the responsible backend had an error or was down while performing the check. + +#### Prefixes + +Though the plugin may have multiple backends enabled, there's a way to specify which backend must be used for a given user: prefixes. +When enabled, `prefixes` allow to check if the username contains a predefined prefix in the form prefix_username and use the configured backend for that prefix. +There's also an option to strip the prefix upon checking user or acl, +so that if a record for `username` exists on a backend with prefix `prefix`, +then both `username` and `prefix_username` would be authenticated/authorized. Notice that the former would +need to loop through all the backends since it carries no prefix, while the latter will only be checked by the correct backend. + +Options to enable and set prefixes are the following: + +``` +auth_opt_check_prefix true +auth_opt_strip_prefix true +auth_opt_prefixes filesprefix, pgprefix, jwtprefix +``` + +Prefixes must meet the declared backends order and number. If amounts don't match, the plugin will default to prefixes disabled. + +Underscores (\_) are not allowed in the prefixes, as a username's prefix will be checked against the first underscore's index. Of course, if a username has no underscore or valid prefix, it'll be checked against all backends. + +#### Superuser checks + +By default `superuser` checks are supported and enabled in all backends but `Files` (see details below). They may be turned off per backend by either setting individual disable options or not providing necessary options such as queries for DB backends, or for all of them by setting this global option to `true`: + +``` +auth_opt_disable_superuser true +``` + +Any other value or missing option will have `superuser` enabled. + +#### ACL access values + +Mosquitto 1.5 introduced a new ACL access value, `MOSQ_ACL_SUBSCRIBE`, which is similar to the classic `MOSQ_ACL_READ` value but not quite the same: + +``` + * MOSQ_ACL_SUBSCRIBE when a client is asking to subscribe to a topic string. + * This differs from MOSQ_ACL_READ in that it allows you to + * deny access to topic strings rather than by pattern. For + * example, you may use MOSQ_ACL_SUBSCRIBE to deny + * subscriptions to '#', but allow all topics in + * MOSQ_ACL_READ. This allows clients to subscribe to any + * topic they want, but not discover what topics are in use + * on the server. + * MOSQ_ACL_READ when a message is about to be sent to a client (i.e. whether + * it can read that topic or not). +``` + +The main difference is that subscribe is checked at first, when a client connects and tells the broker it wants to subscribe to some topic, while read is checked when an actual message is being published to that topic, which makes it particular. +So in practice you could deny general subscriptions such as # by returning false from the acl check when you receive `MOSQ_ACL_SUBSCRIBE`, but allow any particular one by returning true on `MOSQ_ACL_READ`. +Please take this into consideration when designing your ACL records on every backend. + +Also, these are the current available values from `mosquitto`: + +``` +#define MOSQ_ACL_NONE 0x00 +#define MOSQ_ACL_READ 0x01 +#define MOSQ_ACL_WRITE 0x02 +#define MOSQ_ACL_SUBSCRIBE 0x04 +``` + +If you're using prior versions then `MOSQ_ACL_SUBSCRIBE` is not available and you don't need to worry about it. + +#### Backend options + +Any other options with a leading ```auth_opt_``` are handed to the plugin and used by the backends. +Individual backends have their options described in the sections below. + +#### Testing + +As of now every backend has proper but really ugly tests in place: they expect services running for each backend, and are also pretty outdated and cumbersome to work with in general. +This issue captures these concerns and a basic plan to refactor tests: . + +You may run all tests (see Testing X for each backend's testing requirements) like this: + +``` +make test +``` + +### Registering checks + +Backends may register which checks they'll run, enabling the option to only check user auth through some backends, for example an HTTP one, while delegating ACL checks to another backend, e.g. Files. +By default, when the option is not present, all checks for that backend will be enabled (unless `superuser` is globally disabled in the case of `superuser` checks). +For `user` and `acl` checks, at least one backend needs to be registered, either explicitly or by default. + +You may register which checks a backend will perform with the option `auth_opt_backend_register` followed by comma separated values of the registered checks, e.g.: + +``` +auth_opt_http_register user +auth_opt_files_register user, acl +auth_opt_redis_register superuser +``` + +Possible values for checks are `user`, `superuser` and `acl`. Any other value will result in an error on plugin initialization. + +### Files + +The `files` backend implements the regular password and acl checks as described in mosquitto. Passwords should be in `PBKDF2`, `Bcrypt` or `Argon2ID` format (for other backends too), see [Hashing](#hashing) for more details about different hashing strategies. Hashes may be generated using the `pw` utility (built by default when running `make`) included in the plugin (or one of your own). Passwords may also be tested using the [pw-test package](https://github.com/iegomez/pw-test). + +Usage of `pw`: + +``` +Usage of ./pw: + -a string + algorithm: sha256 or sha512 (default "sha512") + -c int + bcrypt ost param (default 10) + -e string + salt encoding (default "base64") + -h string + hasher: pbkdf2, argon2 or bcrypt (default "pbkdf2") + -i int + hash iterations: defaults to 100000 for pbkdf2, please set to a reasonable value for argon2 (default 100000) + -l int + key length, recommended values are 32 for sha256 and 64 for sha512 + -m int + memory for argon2 hash (default 4096) + -p string + password + -pl int + parallelism for argon2 (default 2) + -s int + salt size (default 16) + +``` + +For this backend `passwords` and `acls` file paths must be given: + +``` +auth_opt_files_password_path /path/to/password_file +auth_opt_files_acl_path /path/to/acl_file +``` + +The following are correctly formatted examples of password and acl files: + +#### Passwords file + +``` +test1:PBKDF2$sha512$100000$2WQHK5rjNN+oOT+TZAsWAw==$TDf4Y6J+9BdnjucFQ0ZUWlTwzncTjOOeE00W4Qm8lfPQyPCZACCjgfdK353jdGFwJjAf6vPAYaba9+z4GWK7Gg== +test2:PBKDF2$sha512$100000$o513B9FfaKTL6xalU+UUwA==$mAUtjVg1aHkDpudOnLKUQs8ddGtKKyu+xi07tftd5umPKQKnJeXf1X7RpoL/Gj/ZRdpuBu5GWZ+NZ2rYyAsi1g== +``` + +#### ACL file + +``` +user test1 +topic write test/topic/1 +topic read test/topic/2 + +user test2 +topic read test/topic/+ + +user test3 +topic read test/# + +pattern read test/%u +pattern read test/%c + +``` + +The `ACLs` file follows mosquitto's regular syntax: [mosquitto(5)](https://mosquitto.org/man/mosquitto-conf-5.html). + +There's no special `superuser` check for this backend since granting a user all permissions on `#` works in the same way. +Furthermore, if this is **the only backend registered**, then providing no `ACLs` file path will default to grant all permissions for authenticated users when doing `ACL` checks (but then, why use a plugin if you can just use Mosquitto's static file checks, right?): if, instead, no `ACLs` file path is provided but **there are more backends registered**, this backend will default to deny any permissions for any user (again, back to basics). + +#### Testing Files + +Proper test files are provided in the repo (see test-files dir) and are needed in order to test this backend. + +### PostgreSQL + +The `postgres` backend allows to specify queries for user, superuser and acl checks to be tested against your schema. + +The following `auth_opt_` options are supported: + +| Option | default | Mandatory | Meaning | +|------------------|-------------|:---------:|----------------------------------------| +| pg_host | localhost | | hostname/address | +| pg_port | 5432 | | TCP port | +| pg_user | | Y | username | +| pg_password | | Y | password | +| pg_dbname | | Y | database name | +| pg_userquery | | Y | SQL for users | +| pg_superquery | | N | SQL for superusers | +| pg_aclquery | | N | SQL for ACLs | +| pg_sslmode | verify-full | N | SSL/TLS mode. | +| pg_sslcert | | N | SSL/TLS Client Cert. | +| pg_sslkey | | N | SSL/TLS Client Cert.

The query + MUST return a single row only (any other number of rows is considered to be + "user not found"), and it MUST return a single column only with the PBKDF2 + password hash. A single `'$1'` in the query string is replaced by the + username attempting to access the broker. + + SELECT pass FROM account WHERE username = $1 limit 1 + + + The SQL query for checking whether a user is a _superuser_ - and thus + circumventing ACL checks - is optional. If it is specified, the query MUST + return a single row with a single value: 0 is false and 1 is true. + A single `'$1`' in the query string is replaced by the + username attempting to access the broker. The following example uses the + same `users` table, but it could just as well reference a distinct table + or view. + + SELECT COUNT(*) FROM account WHERE username = $1 AND super = 1 + + The SQL query for checking ACLs is optional, but if it is specified, the + `postgres` backend can try to limit access to particular topics or topic branches + depending on the value of a database table. The query MAY return zero or more + rows for a particular user, each returning EXACTLY one column containing a + topic (wildcards are supported). A single `'$1`' in the query string is + replaced by the username attempting to access the broker, and a single `'$2`' is + replaced with the integer value `1` signifying a read-only access attempt + (SUB) or `2` signifying a read-write access attempt (PUB). + + In the following example, the table has a column `rw` containing 1 for + readonly topics, 2 for writeonly topics and 3 for readwrite topics: + + SELECT topic FROM acl WHERE (username = $1) AND rw = $2 + + +When option pg_superquery is not present, Superuser check will always return false, hence there'll be no superusers. + +When option pg_aclquery is not present, AclCheck will always return true, hence all authenticated users will be authorized to pub/sub to any topic. + +Example configuration: + +``` +auth_opt_pg_host localhost +auth_opt_pg_port 5432 +auth_opt_pg_dbname appserver +auth_opt_pg_user appserver +auth_opt_pg_password appserver +auth_opt_pg_connect_tries 5 +auth_opt_pg_userquery select password_hash from "user" where username = $1 and is_active = true limit 1 +auth_opt_pg_superquery select count(*) from "user" where username = $1 and is_admin = true +auth_opt_pg_aclquery select distinct 'application/' || a.id || '/#' from "user" u inner join organization_user ou on ou.user_id = u.id inner join organization o on o.id = ou.organization_id inner join application a on a.organization_id = o.id where u.username = $1 and $2 = $2 + +``` + +**DB connect tries**: on startup, depending on `pg_connect_tries` option, the plugin will try to connect and ping the DB a max number of times or forever every 2 seconds. +By default it will try to reconnect forever to maintain backwards compatibility and avoid issues when `mosquitto` starts before the DB service does, +but you may choose to ping a max amount of times by setting any positive number. +If given 0, the DB will try to connect only once, which would be the same as setting the option to 1. + +#### Password hashing + +For instructions on how to set a backend specific hasher or use the general one, see [Hashing](#hashing). + +#### Testing Postgres + +In order to test the postgres backend, a simple DB with name, user and password "go_auth_test" is expected. + +User, database and test DB tables may be created with these commands: + +```sql +create user go_auth_test with login password 'go_auth_test'; +create database go_auth_test with owner go_auth_test; +``` + +```sql +create table test_user( +id bigserial primary key, +username character varying (100) not null, +password_hash character varying (200) not null, +is_admin boolean not null); +``` + +```sql +create table test_acl( +id bigserial primary key, +test_user_id bigint not null references test_user on delete cascade, +topic character varying (200) not null, +rw int not null); +``` + +### Mysql + +The `mysql` backend works almost exactly as the `postgres` one, except for a few configurations and that options start with `mysql_` instead of `pg_`. +One change has to do with the connection protocol, either a Unix socket or tcp (options are unix or tcp).

If the `Issuer` claim is not contained in this list of valid hosts, the authorization will fail. Special +value `*` means "any host" and is intended for testing/development purposes only - NEVER use this in production! + +If the option `jwt_superuser_uri` is not set then `superuser` checks are disabled for this mode. + +For all URIs, the backend will send a request with the `Authorization` header set to `Bearer token`, where token should be a correct JWT token and corresponds to the `username` received from Mosquitto. + +When `jwt_parse_token` is set, the backend will parse the token using `jwt_secret` and extract the username from either the claim's `Subject` (`sub` field), or from the `username` field when `jwt_userfield` is set to `Username`. This `username` will be sent along other params in all requests, and the `Authorization` header will be set to `Bearer token` as usual. + +Notice that failing to provide `jwt_secret` or passing a wrong one will result in an error when parsing the token and the request will not be made. +Set these options only if you intend to keep the plugin synced with your JWT service and wish for the former to pre-parse the token. + +##### Response mode + +When response mode is set to `json`, the backend expects the URIs to return a status code (if not 2XX, unauthorized) and a json response, consisting of two fields: + +- Ok: bool +- Error: string + +If either the status is different from 2XX or `Ok` is false, auth will fail (not authenticated/authorized). In the latter case, an `Error` message stating why it failed will be included. + +When response mode is set to `status`, the backend expects the URIs to return a simple status code (if not 2XX, unauthorized). + +When response mode is set to `text`, the backend expects the URIs to return a status code (if not 2XX, unauthorized) and a plain text response of simple "ok" when authenticated/authorized, and any other message (possibly an error message explaining failure to authenticate/authorize) when not. + +##### Params mode + +When params mode is set to `json`, the backend will send a json encoded string with the relevant data. For example, for acl check, this will get sent: + +```json +{ + "topic": "mock/topic", + "clientid": "mock_client", + "acc": 1 // 1 is read, 2 is write, 3 is readwrite, 4 is subscribe +} +``` + +When set to `form`, it will send params like a regular html form post, so acc will be a string instead of an int. + +*Important*: Please note that when using JWT, username and password are not needed, so for user and superuser check the backend will send an empty string or empty form values. On the other hand, all three cases will set the "authorization" header with the jwt token, which mosquitto will pass to the plugin as the regular "username" param. + +*Update: The username is expected to be set at the Subject field of the JWT claims (it was expected at Username earlier).* + +To clarify this, here's an example for connecting from a javascript frontend using the Paho MQTT js client (notice how the jwt token is set in userName and password has any string as it will not get checked): + +```javascript +initMqttClient(applicationID, mode, devEUI) { + const hostname = window && window.location && window.location.hostname; + let wsbroker = hostname; //mqtt websocket enabled broker + let wsport = 1884; // port for above + let date = new Date(); + let clientid = this.getRand() + "_" + date.getTime(); + console.log("Trying to connect to mqtt with hostname: " + hostname + " and clientid " + clientid); + let mqttClient = new window.Paho.MQTT.Client(wsbroker, wsport, + clientid); + + mqttClient.onConnectionLost = function (responseObject) { + console.log("connection lost: " + responseObject.errorMessage); + }; + mqttClient.onMessageArrived = function (message) { + console.log(message.destinationName, ' -- ', message.payloadString); + }; + + let that = this; + + let sslOption = true; + if(hostname == "localhost") { + sslOption = false; + } + + let options = { + timeout: 3, + userName: this.getToken(), + password: "any", + useSSL: sslOption, + keepAliveInterval: 3600, + reconnect: true, + onSuccess: function () { + console.log("mqtt connected"); + // Connection succeeded; subscribe to our topic, you can add multile lines of these + + let topic = 'application/' + applicationID + '/device/' + devEUI + '/data'; + console.log("Subscribing to topic " + topic); + mqttClient.subscribe(topic, {qos: 0}); + + }, + onFailure: function (message) { + console.log("Connection failed: " + message.errorMessage); + } + }; + + mqttClient.connect(options); + return mqttClient; + } +``` + +#### Local mode + +When set to `local` mode, the backend will try to validate JWT tokens against a DB backend, either `postgres` or `mysql`, given by the `jwt_db option`. +Options for the DB connection are the almost the same as the ones given in the Postgres and Mysql backends but prefixed with `jwt_`, e.g.: + +``` +auth_opt_jwt_pg_host localhost +``` + +The difference is that a specific `jwt_userquery` returning a count must be given since JWT backend won't use the `password` passed along by `mosquitto`, +but instead should only use the `username` derived from the JWT token, e.g.: + +``` +auth_opt_jwt_userquery select count(*) from test_user where username = $1 limit 1 +``` + +Thus, the following specific JWT local `auth_opt_` options are supported: + + +| Option | default | Mandatory | Meaning | +| -----------------| ----------------- | :---------: | -------------------------------------------------------- | +| jwt_db | postgres | N | The DB backend to be used, either `postgres` or `mysql` | +| jwt_userquery | | Y | SQL query for users | + + +Notice that general `jwt_secret` is mandatory when using this mode. +`jwt_userfield` is still optional and serves as a mean to extract the username from either the claim's `Subject` (`sub` field), + or from the `username` field when `jwt_userfield` is set to `Username` + +As mentioned, only the `userquery` must not be prefixed by the underlying DB, and now expects an integer result instead of a password hash, as the JWT token needs no password checking. +An example of a different query using either DB is given for the user query. + +For postgres: + +``` +auth_opt_jwt_userquery select count(*) from "user" where username = $1 and is_active = true limit 1 +``` + +For mysql: + +``` +auth_opt_jwt_userquery select count(*) from "user" where username = ? and is_active = true limit 1 +``` + +*Important note:* + +Since local JWT follows the underlying DB backend's way of working, both of these hold true: + +- When option jwt_superquery is not present, Superuser check will always return false, hence there'll be no superusers. +- When option jwt_aclquery is not present, AclCheck will always return true, hence all authenticated users will be authorized to pub/sub to any topic. + + +#### JS mode + +When set to `js` JWT will act in JS mode, which allows to run a JavaScript interpreter VM to conduct checks. Options for this mode are: + +| Option | default | Mandatory | Meaning | +| ------------------------------| --------------- | :---------: | ----------------------------------------------------- | +| jwt_js_stack_depth_limit | 32 | N | Max stack depth for the interpreter | +| jwt_js_ms_max_duration | 200 | N | Max execution time for a hceck in milliseconds | +| jwt_js_user_script_path | | Y | Relative or absolute path to user check script | +| jwt_js_superuser_script_path | | Y | Relative or absolute path to superuser check script | +| jwt_js_acl_script_path | | Y | Relative or absolute path to ACL check script | + +This mode expects the user to define JS scripts that return a boolean result to the check in question. + +The backend will pass `mosquitto` provided arguments along, that is `token` for both `user` and `superuser` check; `token`, `topic`, `clientid` and `acc` for `ACL` checks. + +Optionally, `username` will be passed as an argument when `auth_opt_jwt_parse_token` option is set. As with remote mode, this will need `auth_opt_jwt_secret` to be set and correct, +and `auth_opt_jwt_userfield` to be optionally set. + +This is a valid, albeit pretty useless, example script for ACL checks (see `test-files/jwt` dir for test scripts): + +``` +function checkAcl(token, topic, clientid, acc) { + if(token != "correct") { + return false; + } + + if(topic != "test/topic") { + return false; + } + + if(clientid != "id") { + return false; + } + + if(acc != 1) { + return false; + } + + return true; +} + +checkAcl(token, topic, clientid, acc); +``` + +With `auth_opt_jwt_parse_token` the signature would be `function checkAcl(token, topic, clientid, acc, username)` instead. + +Finally, this mode uses [otto](https://github.com/robertkrimen/otto) under the hood to run the scripts. Please check their documentation for supported features and known limitations. + +#### Files mode + +When set to `files` JWT will run in Files mode, which allows to check user ACLs from a given file. +These ACLs follow the exact same syntax and semantics as those from the [Files](#files) backend. + +Options for this mode are: + +| Option | default | Mandatory | Meaning | +| ------------------------------| --------------- | :---------: | --------------------- | +| jwt_files_acl_path | | Y | Path to ACL files | + + +Notice there's no `passwords` file option since usernames come from parsing the JWT token and no password check is required. +Thus, you should be careful about general ACL rules and prefer to explicitly set rules for each valid user. + +If this shows to be a pain, I'm open to add a file that sets valid `users`, +i.e. like the `passwords` file for regular `Files` backend but without actual passwords. + +If you run into the case where you want to grant some general access but only to valid registered users, +and find that duplicating rules for each of them in ACLs file is really a pain, please open an issue for discussion. + +#### Password hashing + +Since JWT needs not to check passwords, there's no need to configure a `hasher`. + +#### Prefixes + +If `prefixes` are enabled the client should prefix their JWT tokens with the `prefix` defined in the `auth options`: the plugin will strip the prefix from the value forwarded by `Mosquitto` so that the token is a valid JWT one. If the client fails to do so, this backend will still work, but since no prefix is recognized, this might incur in the overhead of potentially checking against some or all of the other backends before checking against the expected JWT one. + +#### Testing JWT + +This backend expects the same test DBs from the Postgres and Mysql test suites. + +### HTTP + +The `http` backend is very similar to the JWT one, but instead of a jwt token it uses simple username/password to check for user auth, and username for superuser and acls. + +The following `auth_opt_` options are supported: + +| Option | default | Mandatory | Meaning | +| ------------------ | --------- | :-------: | ---------------------------------- | +| http_host | | Y | IP address,will skip dns lookup | +| http_port | | Y | TCP port number | +| http_getuser_uri | | Y | URI for check username/password | +| http_superuser_uri | | N | URI for check superuser | +| http_aclcheck_uri | | Y | URI for check acl | +| http_with_tls | false | N | Use TLS on connect | +| http_verify_peer | false | N | Whether to verify peer for tls | +| http_response_mode | status | N | Response type (status, json, text) | +| http_params_mode | json | N | Data type (json, form) | +| http_timeout | 5 | N | Timeout in seconds | +| http_user_agent | mosquitto | N | User Agent to use in requests | +| http_method | POST | N | Http method used (POST, GET, PUT) | + +#### Response mode + +When response mode is set to `json`, the backend expects the URIs to return a status code (if not 2XX, unauthorized) and a json response, consisting of two fields: + +- Ok: bool +- Error: string + +If either the status is different from 2XX or `Ok` is false, auth will fail (not authenticated/authorized). In the latter case, an `Error` message stating why it failed will be included. + +When response mode is set to `status`, the backend expects the URIs to return a simple status code (if not 2XX, unauthorized). + +When response mode is set to `text`, the backend expects the URIs to return a status code (if not 2XX, unauthorized) and a plain text response of simple "ok" when authenticated/authorized, and any other message (possibly an error message explaining failure to authenticate/authorize) when not. + +#### Params mode + +When params mode is set to `json`, the backend will send a json encoded string with the relevant data. For example, for user authentication, this will get sent: + +```json +{ + "username": "user", + "password": "pass", + "clientid": "clientid" +} +``` + +When set to `form`, it will send params like a regular html form post. + +#### Testing HTTP + +This backend has no special requirements as the http servers are specially mocked to test different scenarios. + +### Redis + +The `redis` backend allows to check user, superuser and acls in a defined format. As with the files and different DB backends, passwords hash must be stored and can be created with the `pw` utility. + +For user check, Redis must contain the KEY `username` and the password hash as value. + +For superuser check, a user will be a superuser if there exists a KEY `username:su` and it returns a string value "true". + +Acls may be defined as user specific or for any user, and as subscribe only (MOSQ_ACL_SUBSCRIBE), read only (MOSQ_ACL_READ), write only (MOSQ_ACL_WRITE) or readwrite (MOSQ_ACL_READ | MOSQ_ACL_WRITE, **not** MOSQ_ACL_SUBSCRIBE) rules. + +For user specific rules, SETS with KEYS "username:sacls", "username:racls", "username:wacls" and "username:rwacls", and topics (supports single level or whole hierarchy wildcards, + and #) as MEMBERS of the SETS are expected for subscribe, read, write and readwrite topics. `username` must be replaced with the specific username for each user containing acls. + +For common rules, SETS with KEYS "common:sacls", "common:racls", "common:wacls" and "common:rwacls", and topics (supports single level or whole hierarchy wildcards, + and #) as MEMBERS of the SETS are expected for read, write and readwrite topics. + +Finally, options for Redis are not mandatory and are the following: + +``` +auth_opt_redis_host localhost +auth_opt_redis_port 6379 +auth_opt_redis_db dbname +auth_opt_redis_password pwd +auth_opt_redis_disable_superuser true +auth_opt_redis_mode cluster +auth_opt_redis_addresses host1:port1,host2:port2,host3:port3 +``` + +When not present, host defaults to "localhost", port to 6379, db to 2 and no password is set. + +#### Cluster + +If you want to use a Redis Cluster as your backend, you need to set `auth_opt_redis_mode` to `cluster` and provide the different addresses as a list of comma separated `host:port` strings with the `auth_opt_redis_addresses` options. +If `auth_opt_redis_mode` is set to another value or not set, Redis defaults to single instance behaviour. If it is correctly set but no addresses are given, the backend will fail to initialize. + +#### Password hashing + +For instructions on how to set a backend specific hasher or use the general one, see [Hashing](#hashing). + +#### Testing Redis + +In order to test the Redis backend, the plugin needs to be able to connect to a redis server located at localhost, on port 6379, without using password and that a database named 2 exists (to avoid messing with the commonly used 0 and 1). + +All these requirements are met with a fresh installation of Redis without any custom configurations (at least when building or installing from the distro's repos in Debian based systems, and probably in other distros too). + +After testing, db 2 will be flushed. + +If you wish to test Redis auth, you may set the `requirepass` option at your `redis.conf` to match the password given in the test case: + +``` +requirepass go_auth_test +``` + +#### Testing Redis Cluster + +To test a Redis Cluster the plugin expects that there's a cluster with 3 masters at `localhost:7000`, `localhost:7001` and `localhost:7002`. The easiest way to achieve this is just running some dockerized cluster such as https://github.com/Grokzen/docker-redis-cluster, which I used to test that the cluster mode is working, but building a local cluster should work just fine. I know that this test is pretty bad, and so are the general testing expectations. I'm looking to replace the whole suite with a proper dockerized environment that can also run automatic tests on pushes to ensure any changes are safe, but that will take some time. + + +### MongoDB + +The `mongo` backend, as the `redis` one, defines some formats to checks user, superuser and acls. +Two collections are defined, one for users and the other for common acls. + +In the first case, a user consists of a "username" string, a "password" string (as always, PBKDF2 hash), a "superuser" boolean, and an "acls" array of rules. +These rules consis of a "topic" string and an int "acc", where 1 means read only, 2 means write only, 3 means readwrite and 4 means subscribe (see ACL access values section for more details). + +Example user: + +```json + { "_id" : ObjectId("5a4e760f708ba1a1601fa40f"), + "username" : "test", + "password" : "PBKDF2$sha512$100000$os24lcPr9cJt2QDVWssblQ==$BK1BQ2wbwU1zNxv3Ml3wLuu5//hPop3/LvaPYjjCwdBvnpwusnukJPpcXQzyyjOlZdieXTx6sXAcX4WnZRZZnw==", + "superuser" : true, + "acls" : [ + { "topic" : "test/topic/1", "acc" : 1 }, + { "topic" : "test/topic/1", "acc" : 4 }, + { "topic" : "single/topic/+", "acc" : 1}, + { "topic" : "hierarchy/#", "acc" : 1 }, + { "topic" : "write/test", "acc" : 2 }, + { "topic" : "test/readwrite/1", "acc" : 3 } + ] + } +``` + +Common acls are just like user ones, but live in their own collection and are applicable to any user. Pattern matching against username or clientid acls should be included here. + +Example acls: + +```json + { "_id" : ObjectId("5a4e760f708ba1a1601fa411"), "topic" : "pattern/%u", "acc" : 1 } + { "_id" : ObjectId("5a4e760f708ba1a1601fa413"), "topic" : "pattern/%c", "acc" : 1 } +``` + +Options for `mongo` are not mandatory and are the following: + +``` +auth_opt_mongo_host localhost +auth_opt_mongo_port 6379 +auth_opt_mongo_dbname dbname +auth_opt_mongo_username user +auth_opt_mongo_password pwd +auth_opt_mongo_users users_collection_name +auth_opt_mongo_acls acls_collection_name +auth_opt_mongo_disable_superuser true +auth_opt_mongo_with_tls true +auth_opt_mongo_insecure_skip_verify false +``` + +The last two set names for the collections to be used for the given database. + +When not set, these options default to: + + host: "localhost" + port: "27017" + username: "" + password: "" + dbame: "mosquitto" + users: "users" + acls: "acls" + with_tls: "false" + insecure_skip_verify: "false" + +If you experience any problem connecting to a replica set, please refer to [this issue](https://github.com/iegomez/mosquitto-go-auth/issues/32). + +#### Password hashing + +For instructions on how to set a backend specific hasher or use the general one, see [Hashing](#hashing). + +#### Testing MongoDB + +Much like `redis`, to test this backend the plugin needs to be able to connect to a mongodb server located at localhost, on port 27017, without using username or password. + +All this requirements are met with a fresh installation of MongoDB without any custom configurations (at least when building or installing from the distro's repos in Debian based systems, and probably in other distros too). + +As with `sqlite`, this backend constructs the collections and inserts relevant data, which are whiped out after testing is done, so no user actions are required. + +If you wish to test Mongo's auth, you'll need to run mongo with the `--auth` flag, have a user `go_auth_test` with password `go_auth_test` with the `dbOwner` role over the `mosquitto_test` DB and uncomment these lines from `mongo_test.go`: + +``` + //authOpts["mongo_username"] = "go_auth_test" + //authOpts["mongo_password"] = "go_auth_test" +``` + +### Custom + +Using the `plugin` package from Go, this project allows to write your own custom backend, +compile it as a shared object and link to it from mosquitto-go-auth. +Check Go pluing [docs](https://golang.org/pkg/plugin/) for more details. + +In order to create your own plugin, you need to declare a main package that exposes the following functions (and uses the logrus package for logging): + +```go +package main + +import ( + log "github.com/sirupsen/logrus" +) + +func Init(authOpts map[string]string, logLevel log.Level) error { + //Initialize your plugin with the necessary options + return nil +} + +func GetUser(username, password, clientid string) (bool, error) { + return false, nil +} + +func GetSuperuser(username string) (bool, error) { + return false, nil +} + +func CheckAcl(username, topic, clientid string, acc int) (bool, error) { + return false, nil +} + +func GetName() string { + return "Your plugin name" +} + +func Halt() { + //Do whatever cleanup is needed. +} + +``` + +Init should initialize anything that your plugin needs from the options passed in authOpts. These options may be given through the configuration as any other one, following the auth_opt_whatever_else pattern. + +If you want to register your custom plugin, you need to add `plugin` to the auth_opt_backends option, and the option `auth_opt_plugin_path` with the absolute path to your-plugin.so. + +GetUser, GetSuperuser and CheckAcl should respond with simple true/false to authenticate/authorize a user or pub/sub. + +GetName is used only for logging purposes, as in debug level which plugin authenticated/authorized a user or pub/sub is logged. + +You can build your plugin with: + +`go build -buildmode=plugin` + +Check the plugin directory for dummy example and makefile. + +#### Testing Custom + +As this option is custom written by yourself, there are no tests included in the project. + + +### gRPC + +The `grpc` backend allows to check for user auth, superuser and acls against a gRPC service. + +The following `auth_opt_` options are supported: + + +| Option | default | Mandatory | Meaning | +| ------------------------- | ----------------- | :---------: | ------------------------------ | +| grpc_host | | Y | gRPC server hostname | +| grpc_port | | Y | gRPC server port number | +| grpc_ca_cert | | N | gRPC server CA cert path | +| grpc_tls_cert | | N | gRPC client TLS cert path | +| grpc_tls_key | | N | gRPC client TLS key path | +| grpc_disable_superuser | false | N | disable superuser checks | +| grpc_fail_on_dial_error | false | N | fail to init on dial error | +| grpc_dial_timeout_ms | 500 | N | dial timeout in ms | + +The last one, `grpc_fail_on_dial_error` indicates if failing to dial the service on initialization should be +treated as a fatal error, or it should only be logged and then an attempt to redial should be made on every +user or ACL check until the connection may be established.
