# Firejail [![Test Status](https://travis-ci.org/netblue30/firejail.svg?branch=master)](https://travis-ci.org/netblue30/firejail) [![Build Status](https://gitlab.com/Firejail/firejail_ci/badges/master/pipeline.svg)](https://gitlab.com/Firejail/firejail_ci/pipelines/) Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, seccomp-bpf and Linux capabilities. It allows a process and all its descendants to have their own private view of the globally shared kernel resources, such as the network stack, process table, mount table. Firejail can work in a SELinux or AppArmor environment, and it is integrated with Linux Control Groups. Written in C with virtually no dependencies, the software runs on any Linux computer with a 3.x kernel version or newer. It can sandbox any type of processes: servers, graphical applications, and even user login sessions. The software includes sandbox profiles for a number of more common Linux programs, such as Mozilla Firefox, Chromium, VLC, Transmission etc. The sandbox is lightweight, the overhead is low. There are no complicated configuration files to edit, no socket connections open, no daemons running in the background. All security features are implemented directly in Linux kernel and available on any Linux computer.

Example: ````` $ firejail --list 1617:netblue:/usr/bin/firejail /usr/bin/firefox-esr 7719:netblue:/usr/bin/firejail /usr/bin/transmission-qt 7779:netblue:/usr/bin/firejail /usr/bin/galculator 7874:netblue:/usr/bin/firejail /usr/bin/vlc --started-from-file file:///home/netblue/firejail-whitelist.mp4 7916:netblue:firejail --list ````` ## Desktop integration Integrate your sandbox into your desktop by running the following two commands: ````` $ firecfg --fix-sound $ sudo firecfg ````` The first command solves some shared memory/PID namespace bugs in PulseAudio software prior to version 9. The second command integrates Firejail into your desktop. You would need to logout and login back to apply PulseAudio changes. Start your programs the way you are used to: desktop manager menus, file manager, desktop launchers. The integration applies to any program supported by default by Firejail. There are about 250 default applications in current Firejail version, and the number goes up with every new release. We keep the application list in [/usr/lib/firejail/firecfg.config](https://github.com/netblue30/firejail/blob/master/src/firecfg/firecfg.config) file. ## Security profiles Most Firejail command line options can be passed to the sandbox using profile files. You can find the profiles for all supported applications in [/etc/firejail](https://github.com/netblue30/firejail/tree/master/etc) directory. If you keep additional Firejail security profiles in a public repository, please give us a link: * https://github.com/chiraag-nataraj/firejail-profiles * https://github.com/triceratops1/fe Use this issue to request new profiles: [#1139](https://github.com/netblue30/firejail/issues/1139) We also keep a list of profile fixes for previous released versions in [etc-fixes](https://github.com/netblue30/firejail/tree/master/etc-fixes) directory . ````` ````` ## Current development version: 0.9.57 ## New Long Term Support (0.9.56-LTS) version released The new version updates the code base to 0.9.56. We target a reduction of approx. 40% of the code by removing rarely used features (chroot, overlay, rlimits, cgroups), incomplete features (private-bin, private-lib), and a lot of instrumentation (build profile feature, tracing, auditing, etc). Sandbox-specific security features such as seccomp, capabilities, filesystem whitelist/blacklist and networking are updated and hardened. ````` firejail (0.9.56-LTS) baseline; urgency=low * code based on Firejail version 0.9.56 * much smaller code base for SUID executable * command line options removed: --audit, --build, --cgroup, --chroot, --get, --ls, --output, --output-stderr, --overlay, --overlay-named, --overlay-tmpfs, --overlay-clean, --private-home, --private-bin, --private-etc, --private-opt, --private-srv, --put, --rlimit*, --trace, --tracelog, --x11*, --xephyr* * compile-time options: --enable-apparmor, --disable-seccomp, --disable-globalcfg, --disable-network, --disable-userns, --disable-whitelist, --disable-suid, --enable-fatal-warnings, --enable-busybox-workaround -- netblue30 Sun, 21 Oct 2018 08:00:00 -0500 ````` The new LTS branch is here: https://github.com/netblue30/firejail/tree/LTSbase ## New commands: ````` --net.print=name|pid If a new network namespace is enabled, print network interface configuration for the sandbox specified by name or PID.
