In the API, -these specifications are represented by a JSON object with the following fields: +Fundamental Protocol +-------------------- -``pre vars`` - A list of symbolic variables introduced in the initial state section of the specification. These variables - are represented by a JSON object containing three fields: +This application is a `JSON-RPC `_ server. Additionally, it maintains a persistent cache of application states and explicitly indicates the state in which each command is to be carried out. -.. _contract-vars: +Transport +~~~~~~~~~ - - ``server name``: The name of the variable on the server. - - ``name``: The "display name" of the variable, used in debugging output. - - ``type``: The :ref:`LLVM` or :ref:`JVM` type of this variable. +The server supports three transport methods: -``pre conds`` - A list of the specification's preconditions, as :ref:`Cryptol terms`. -``pre allocated`` - A list of allocations in the initial state section of the specification. In preconditions, - allocations specify that the function being verified expects a pointer to the allocated memory - to exist. An allocation is a JSON object containing four fields, one of which is optional: +``stdio`` + in which the server communicates over ``stdin`` and ``stdout`` + + -.. _allocation: +Socket + in which the server communicates over ``stdin`` and ``stdout`` + + - - ``server name``: The name by which the allocation is referred to on the server. - - ``type``: The :ref:`LLVM` or :ref:`JVM` type of the data for which space is being allocated. - - ``mutable``: A Boolean value indicating whether the allocated memory is mutable or not. - - ``alignment``: An integer value indicating where the start of the allocated memory should - be aligned. This value must be a power of two, and the allocated memory may be aligned at - any multiple of it. The field *must* be ``null`` in JVM specifications, and *may* be ``null`` - in LLVM specifications. +HTTP + in which the server communicates over HTTP + + +In both ``stdio`` and socket mode, messages are delimited using `netstrings. `_ -``pre points to`` - A list of 'points-to' relationships in the initial state section of the specification. These - relationships are captured in a JSON object containing four fields, two of which are optional: -.. _points-to: +Application State +~~~~~~~~~~~~~~~~~ - - ``pointer``: A :ref:`Crucible Setup value` representing the pointer. - - ``points to``: A :ref:`Crucible Setup value` representing the referent of ``pointer``. - - ``check points to type``: An optional description of a type to check the ``points to`` value against. - If the description is ``null``, then this has no effect. The description is represented as a JSON - object containing a tag named ``check against``, with any further fields determined by this tag. - These tag values can be: +According to the JSON-RPC specification, the ``params`` field in a message object must be an array or object. In this protocol, it is always an object. While each message may specify its own arguments, every message has a parameter field named ``state``. - + ``pointer type``: Check the type of the ``points to`` value against the type that the ``pointer`` - value's type points to. - + ``casted type``: Check the type of the ``points to`` value against the provided type. There is - an additional field ``type``, which contains the :ref:`LLVM` or :ref:`JVM` - type to check against. +When the first message is sent from the client to the server, the ``state`` parameter should be initialized to the JSON null value ``null``. Replies from the server may contain a new state that should be used in subsequent requests, so that state changes executed by the request are visible. Prior versions of this protocol represented the initial state as the empty array ``[]``, but this is now deprecated and will be removed. - - ``condition``: An optional condition, represented as a :ref:`Cryptol term`. - If the ``condition`` is not ``null``, then the ``pointer`` value will only point to the ``points to`` - value if the ``condition`` holds. +In particular, per JSON-RPC, non-error replies are always a JSON object that contains a ``result`` field. The result field always contains an ``answer`` field and a ``state`` field, as well as ``stdout`` and ``stderr``. -``argument vals`` - A list of :ref:`Crucible Setup values` representing the arguments to the function being verified. -``post vars`` - A list of variables in the final state section of the specification. While in many cases this - list will be empty, it is sometimes useful to specify that functions return arbitrary values. - These variables are represented in the same way as :ref:`above`. +``answer`` + The value returned as a response to the request (the precise contents depend on which request was sent) + + -``post conds`` - A list of the specification's postconditions, as :ref:`Cryptol terms`. +``state`` + The state, to be sent in subsequent requests. If the server did not modify its state in response to the command, then this state may be the same as the one sent by the client. + + -``post allocated`` - A list of allocations in the final state section of the specification. In postconditions, - allocations specify that the function being verified allocated memory. An allocation is - represented in the same was as :ref:`above`. +``stdout`` and ``stderr`` + These fields contain the contents of the Unix ``stdout`` and ``stderr`` file descriptors. They are intended as a stopgap measure for clients who are still in the process of obtaining structured information from the libraries on which they depend, so that information is not completely lost to users. However, the server may or may not cache this information and resend it. Applications are encouraged to used structured data and send it deliberately as the answer. + + +The precise structure of states is considered an implementation detail that could change at any time. Please treat them as opaque tokens that may be saved and re-used within a given server process, but not created by the client directly. -``post points tos`` - A list of 'points-to' relationships in the final state section of the specification. These - relationships are represented in the same was as :ref:`above`. -``return val`` - An optional :ref:`Crucible Setup value` specifying the expected return value of the function being verified. +Summary +------- -.. _proof-scripts: +A remote server for `SAW `_ for verifying programs with a featureset similar to SAWScript. -Proof Scripts -============= -SAW allows one to direct a verification task using a proof script, which is simply a sequence of proof -tactics to apply. Very commonly, the proof script provided in a verification task is simply an instruction -to use an external SAT/SMT solver such as ABC, Yices, or Z3. +Methods +------- -A proof script is represented as a JSON object with a single field: +SAW RPC Server (command) +~~~~~~~~~~~~~~~~~~~~~~~~ -``tactics`` - A list of proof tactics to apply to the context/goal. A proof tactic is represented as a JSON object - containing a tag named ``tactic``, with any further fields determined by this tag. These tag values can be: - ``use prover`` - Apply an external prover to the goal. There is an additional field ``prover`` which is a JSON object - with a field ``name`` specifying what prover to use (one of ``abc``, ``cvc4``, ``rme``, ``yices``, or ``z3``), - and a field ``uninterpreted functions`` when ``name`` is one of ``cvc4``, ``yices``, or ``z3``. This - field is a list of names of functions taken as uninterpreted/abstract. +``module name`` + Name of module to load. + + +Load the specified Cryptol module. - ``unfold`` - Unfold terms in the context/goal.

There is an additional field ``rules``, a name bound to a simpset on the server. +``file`` + File to load as a Cryptol module. + + +Load the given file as a Cryptol module. - ``assume unsat`` - Assume the goal is unsatisfiable, which in the current implementation of SAW should be interpreted as - assuming the property being checked to be true. This is likely to change in the future. - ``trivial`` - States that the goal should be trivially true (either the constant ``True`` or a function that immediately - returns ``True``. This tactic fails if that is not the case. +SAW RPC Server (command) +~~~~~~~~~~~~~~~~~~~~~~~~ -.. _setup-values: -Crucible Setup Values -===================== +``name`` + The name to assign to the expression for later reference. + + -Setup Values encompass all values that can occur during symbolic execution, including Cryptol terms, -pointers, arrays, and structures. They are used extensively when writing the specifications provided to the -``verify`` commands. Setup Values are represented as JSON objects containing a tag field, ``setup value``, -that determines the other fields. This tag value can be: +``expression`` + The expression to save. + + +Save a term to be referenced later by name. -``named`` - A term previously saved on the server. There is an additional field ``name`` giving the name bound to the - term on the server. -``null`` - A null/empty value. +SAW RPC Server (command) +~~~~~~~~~~~~~~~~~~~~~~~~ -``Cryptol`` - A Cryptol term. There is an additional field ``expression`` containing a Cryptol expression. -``array`` - An array value.

In the API, +these specifications are represented by a JSON object with the following fields: + +``pre vars`` + A list of symbolic variables introduced in the initial state section of the specification. These variables + are represented by a JSON object containing three fields: + +.. _contract-vars: + + - ``server name``: The name of the variable on the server. + - ``name``: The "display name" of the variable, used in debugging output. + - ``type``: The :ref:`LLVM` or :ref:`JVM` type of this variable. + +``pre conds`` + A list of the specification's preconditions, as :ref:`Cryptol terms`. + +``pre allocated`` + A list of allocations in the initial state section of the specification. In preconditions, + allocations specify that the function being verified expects a pointer to the allocated memory + to exist. An allocation is a JSON object containing four fields, one of which is optional: + +.. _allocation: + + - ``server name``: The name by which the allocation is referred to on the server. + - ``type``: The :ref:`LLVM` or :ref:`JVM` type of the data for which space is being allocated. + - ``mutable``: A Boolean value indicating whether the allocated memory is mutable or not. + - ``alignment``: An integer value indicating where the start of the allocated memory should + be aligned. This value must be a power of two, and the allocated memory may be aligned at + any multiple of it. The field *must* be ``null`` in JVM specifications, and *may* be ``null`` + in LLVM specifications. + +``pre points to`` + A list of 'points-to' relationships in the initial state section of the specification. These + relationships are captured in a JSON object containing four fields, two of which are optional: + +.. _points-to: + + - ``pointer``: A :ref:`Crucible Setup value` representing the pointer. + - ``points to``: A :ref:`Crucible Setup value` representing the referent of ``pointer``. + - ``check points to type``: An optional description of a type to check the ``points to`` value against. + If the description is ``null``, then this has no effect. The description is represented as a JSON + object containing a tag named ``check against``, with any further fields determined by this tag. + These tag values can be: + + + ``pointer type``: Check the type of the ``points to`` value against the type that the ``pointer`` + value's type points to. + + ``casted type``: Check the type of the ``points to`` value against the provided type. There is + an additional field ``type``, which contains the :ref:`LLVM` or :ref:`JVM` + type to check against. + + - ``condition``: An optional condition, represented as a :ref:`Cryptol term`. + If the ``condition`` is not ``null``, then the ``pointer`` value will only point to the ``points to`` + value if the ``condition`` holds. + +``argument vals`` + A list of :ref:`Crucible Setup values` representing the arguments to the function being verified. + +``post vars`` + A list of variables in the final state section of the specification. While in many cases this + list will be empty, it is sometimes useful to specify that functions return arbitrary values. + These variables are represented in the same way as :ref:`above`. + +``post conds`` + A list of the specification's postconditions, as :ref:`Cryptol terms`. + +``post allocated`` + A list of allocations in the final state section of the specification. In postconditions, + allocations specify that the function being verified allocated memory. An allocation is + represented in the same was as :ref:`above`. + +``post points tos`` + A list of 'points-to' relationships in the final state section of the specification. These + relationships are represented in the same was as :ref:`above`. + + +``return val`` + An optional :ref:`Crucible Setup value` specifying the expected return value of the function being verified. + +.. _proof-scripts: + +Proof Scripts +============= + +SAW allows one to direct a verification task using a proof script, which is simply a sequence of proof +tactics to apply. Very commonly, the proof script provided in a verification task is simply an instruction +to use an external SAT/SMT solver such as ABC, Yices, or Z3. + +A proof script is represented as a JSON object with a single field: + +``tactics`` + A list of proof tactics to apply to the context/goal. A proof tactic is represented as a JSON object + containing a tag named ``tactic``, with any further fields determined by this tag. These tag values can be: + + ``use prover`` + Apply an external prover to the goal. There is an additional field ``prover`` which is a JSON object + with a field ``name`` specifying what prover to use (one of ``abc``, ``cvc4``, ``rme``, ``yices``, or ``z3``), + and a field ``uninterpreted functions`` when ``name`` is one of ``cvc4``, ``yices``, or ``z3``. This + field is a list of names of functions taken as uninterpreted/abstract. + + ``unfold`` + Unfold terms in the context/goal. There is an additional field ``names``, a list of the names bound on + the server to unfold. + + ``beta reduce goal`` + Perform a single beta reduction on the proof goal. + + ``evaluate goal`` + Fully evaluate the proof goal. There is an additional field ``uninterpreted functions``, a list of names + of functions taken as uninterpreted/abstract. + + ``simplify`` + Simplify the context/goal. There is an additional field ``rules``, a name bound to a simpset on the server. + + ``assume unsat`` + Assume the goal is unsatisfiable, which in the current implementation of SAW should be interpreted as + assuming the property being checked to be true. This is likely to change in the future. + + ``trivial`` + States that the goal should be trivially true (either the constant ``True`` or a function that immediately + returns ``True``. This tactic fails if that is not the case. + +.. _setup-values: + +Crucible Setup Values +===================== + +Setup Values encompass all values that can occur during symbolic execution, including Cryptol terms, +pointers, arrays, and structures. They are used extensively when writing the specifications provided to the +``verify`` commands. Setup Values are represented as JSON objects containing a tag field, ``setup value``, +that determines the other fields. This tag value can be: + +``named`` + A term previously saved on the server. There is an additional field ``name`` giving the name bound to the + term on the server. + +``null`` + A null/empty value. + +``Cryptol`` + A Cryptol term. There is an additional field ``expression`` containing a Cryptol expression. + +``array`` + An array value. There is an additional field ``elements`` which is a list of :ref:`Crucible Setup values` + to populate the array with. + +``struct`` + A struct value. There is an additional field ``fields`` which is a list of :ref:`Crucible Setup values` + to populate the struct with. + +``field`` + A field of a struct. There are two additional fields: + + - ``base``: A :ref:`Crucible Setup value`, the structure containing the field to assign to. + - ``field``: The name of the field to assign to. + +``element lvalue`` + An element of an array. Theer are two additional fields: + + - ``base``: A :ref:`Crucible Setup value`, the array to be indexed for assignment. + - ``index``: An integer giving the index into the array to be assigned to. + +``global initializer`` + A constant global initializer value. There is an additional field ``name`` giving the name of the + global variable on the server to access the initializer of. + +``global lvalue`` + A global variable to be assigned to. There is an additional field ``name`` giving the name of the global + variable on the server that is to be assigned to. + +.. _llvm-types: + +LLVM Types +========== + +For most commands involving the introduction of variables or the allocation of space, the type of data to +be stored must be provided. Since SAW supports both LLVM and JVM verification, the types from these +respective architectures must have JSON representations. Both LLVM and JVM types are represented as JSON +objects with a tag field to indicate any additional information that must/might be present. + +The tag field is named ``type``. This tag value can be: + +``primitive type`` + An LLVM primitive type. This is an additional field ``primitive`` which can be any of the following: + + - ``label``: An LLVM label. + - ``void``: The LLVM void type. + - ``integer``: An LLVM integer. There is an additional field ``size``, an integer giving the number of + bytes in the integer type. + - ``float``: An LLVM float. There is an additional field ``float type`` which can be any of the following: + + + ``half`` + + ``float`` + + ``double`` + + ``fp128`` + + ``x86_fp80`` + + ``PPC_fp128`` + + - ``X86mmx``: An x86 SIMD instruction. + - ``metadata``: LLVM metadata. + +``type alias`` + A type alias.

Its accompanying Python doc strings describe the various ways it can be +used. Below is a brief summary: + +`saw.connect()`, when provided no arguments, will attempt the following in order: + +1. If the environment variable ``SAW_SERVER`` is set and refers to an + executable, it is assumed to be a `saw-remote-api` executable and will be + used for the duration of the script. +2. If the environment variable ``SAW_SERVER_URL`` is set, it is assumed to be + the URL for a running SAW server in ``http`` mode and will be connected to. + (N.B., this can be a local server or a server running in a docker image.) +3. If an executable ``saw-remote-api`` is available on the ``PATH`` it is + assumed to be a SAW server and will be used for the duration of the script. + +Additional arguments and options are documented with the function. + +Notable, the `reset_server` keyword can be used to connect to a running server +and reset it, ensuring states from previous scrips have been cleared. E.g., +`saw.connect(reset_server=True)`. + + +## Acquiring a SAW Server + +There are several ways a server executable can be obtained. + +### Server executables + +An executable of the server is included in the SAW release/nightly tarballs. + +If using a SAW [release](https://github.com/GaloisInc/saw-script/releases), it +is recommended to use `v0.8` or greater if possible. (`v0.7` _does_ include the +server and may work for individual use cases, but running repeated scripts +against the same persistent server will not work as intended.) + +Nightly server builds can be found as `Artifacts` of the [Nightly +Builds](https://github.com/GaloisInc/saw-script/actions/workflows/nightly.yml) +github action. I.e., go to the `Nightly Builds` Github Action, click on a +successful build, scroll to the bottom and under `Artifacts` a Linux, Windows, +and MacOS tarball will be listed. (Apologies... we need to make these easier to +find...) + +### Server docker images + +Docker images for the saw server are currently uploaded to +[DockerHub](https://hub.docker.com/r/galoisinc/saw-remote-api). + +These images are set up to run as HTTP `saw-remote-api` servers, e.g.: + +``` +docker run --name=saw-remote-api -d \ + -p 8080:8080 \ + galoisinc/saw-remote-api:TAG +``` + +(where `TAG` is either `latest` or `nightly`) will launch a server listening at +`http://localhost:8080/`. (As of March 2020, `nightly` is recommended, as the +server in the last official release (i.e., the one accompanying SAW `v0.7`) +contains some non-trivial bugs that greatly limit its utility.) + +The `-v` option to `docker run` can be used to load files into the docker +server's working directory so they can be loaded into the server at the request +of python scripts. E.g., `-v PATH_TO_FILES:/home/saw/files/` will upload the +contents of the host machine's directory `PATH_TO_FILES` to the +`/home/saw/files/` directory in the docker container, which corresponds to the +relative path `files/` for the SAW server. (If desired, it can be useful to +place files in a location in the Docker container such that the same relative +paths in scripts refer to the same files in the host machine and docker +container.) + +### Building from Source + +If this repository is checked out and the build directions are successfully run, +`cabal v2-exec which saw-remote-api` should indicate where the server executable has +been stored by `cabal`. + +Alternatively `cabal v2-install saw-remote-api` should install the server +executable into the user's `~/.cabal/bin` directory (or similar), which (if +configured properly) should then appear as `saw-remote-api` in a user's `PATH`. + + +# Running Python SAW verification scripts + +Once the server is setup and any path variables are setup as desired, the +Python (>= v3.8) client can be installed using +[`poetry`](https://python-poetry.org/docs/#installation) as follows: + +``` +$ cd saw-remote-api/python +$ poetry install +``` + +Then the tests or individual scripts can be run as follows: +``` +$ poetry run python -m unittest discover tests/saw +$ poetry run python tests/saw/test_salsa20.py +``` + +If leveraging environment variables is undesirable, the scripts themselves can +specify a command to launch the server, e.g.: + +``` +saw.connect(COMMAND) +``` + +where `COMMAND` is a command to launch a new SAW server in socket mode. + +Or a server URL can be specified directly in the script, e.g.: + +``` +saw.connect(url=URL) +``` + +where `URL` is a URL for a running SAW server in HTTP mode. + +## Running Verification Scripts from a clean state + +To ensure any previous server state is cleared when running a SAW Python script +against a persistent server (e.g., one running in HTTP mode in a different process), +the `reset_server` keyword can be passed to `saw.connect()`. E.g., + +``` +saw.connect(url="http://localhost:8080/", reset_server=True) +``` + +will connect to a SAW server running at `http://localhost:8080/` and will +guarantee any previous state on the server
