LSVerifier

LSVerifier

LSVerifier is a command-line tool for formal verification of large ANSI-C projects in a single run.

It leverages the ESBMC model checker as its core verification engine.

Version

Version	Improviments
v0.3.0	Support specific class of property verification; Support for large software; Prioritized functions verification, Disable invalid pointer verification.
v0.2.0	Support for libraries dependencies; Recursive verification.

Installation

Install LSVerifier

From repository

1. Clone the repository:

$ git clone https://github.com/janislley/lsverifier.git

1. Install using pip:

$ cd LSVerifier
$ pip3 install .

From Pypi

$ pip3 install lsverifier

Usage

1. Verify a project

$ cd <project-root>
$ lsverifier -r -f

For projects with third-party library dependencies, use -l option to specify header paths:

$ lsverifier -r -f -l dep.txt

See an example of dep.txt below:

  /usr/include/glib-2.0/
  /usr/lib/x86_64-linux-gnu/glib-2.0/include/extcap/
  extcap/
  plugins/epan/ethercat/
  plugins/epan/falco_bridge/
  plugins/epan/wimaxmacphy/
  epan/crypt/
  ...

2. Verify a single C file

$ lsverifier -f -fl file.c

3. Verify C files using a priorization algorithm

If you want to verify a project using a prioritization scheme, run:

$ cd <project-root>
$ lsverifier -r -fp

4. Verify an entire project by providing the folder path as an argument

To set the folder path parameter, you should use -d:

lsverifier -r -f -l dep.txt -d project-root/

5. Verify C files using a predefined class of properties

In the project that you want to verify, run:

$ lsverifier -r -f -p memory-leak-check,overflow-check,deadlock-check,data-races-check

See more properties on tool help.

Verification report

The verification results will be saved in output folder, automatically created in the current verification path. Each verification run generates two files:

• lsverifier-DATE.log: Contains the verification output log.
• lsverifier-DATE.csv: Contains the verification results in CSV format.
