libsbox

Libsbox is sandbox desined for evaluating submissions in programming contests.

Why libsbox?

• Performance. Libsbox need only around 2ms to start sandbox, which is close to simple exec()
• Ease of use. You can include libsbox.h to easily run anything in sandbox.

Getting started

These instructions will guide you through the installation process of libsbox.

Prerequisites

• C++17 compiler, especially std::filesystem support

• linux kernel version 5 or higher (may also work with late 4.* versions)
• cgroup v1 heirarchy mounted in /sys/fs/cgroup

Installing

1. Build sources

mkdir build
cd build
cmake ..
make

2. Install libsbox

sudo make install

Following will be installed:

• /usr/include/libsbox.h - libsbox C++ header
• /usr/lib/libsbox.a - static library
• /usr/lib/libsbox.so - dynamic library
• /usr/bin/libsboxd - libsbox daemon binary
• /etc/libsbox/conf.json - libsbox configuration file
• invokers group created

[comment]: # (3. To allow users use libsbox add them to invokers group TODO

sudo usermod -aG invokers username
```)

If you started libsboxd yourself and want to validate that everything is good run sudo make tests
