NAME         top

       profile - Security profile file syntax for Firejail

USAGE         top

       firejail --profile=filename.profile
       firejail --profile=profile_name

DESCRIPTION         top

       Several command line options can be passed to the program using
       profile files. Firejail chooses the profile file as follows:

       1. If a profile file is provided by the user with --profile
       option, the profile file is loaded. If a profile name is given,
       it is searched for first in the ~/.config/firejail directory and
       if not found then in  /etc/firejail directory. Profile names do
       not include the .profile suffix.  Example:

              $ firejail --profile=/home/netblue/icecat.profile icecat
              Reading profile /home/netblue/icecat.profile
              [...]

              $ firejail --profile=icecat icecat-wrapper.sh
              Reading profile /etc/firejail/icecat.profile
              [...]

       2. If a profile file with the same name as the application is
       present in ~/.config/firejail directory or in /etc/firejail, the
       profile is loaded. ~/.config/firejail takes precedence over
       /etc/firejail. Example:

              $ firejail icecat
              Command name #icecat#
              Found icecat profile in /home/netblue/.config/firejail
              directory
              Reading profile
              /home/netblue/.config/firejail/icecat.profile
              [...]

       3. Use a default.profile file if the sandbox is started by a
       regular user, or a server.profile file if the sandbox is started
       by root. Firejail looks for these files in ~/.config/firejail
       directory, followed by /etc/firejail directory.  To disable
       default profile loading, use --noprofile command option. Example:

              $ firejail
              Reading profile /etc/firejail/default.profile
              Parent pid 8553, child pid 8554
              Child process initialized
              [...]

              $ firejail --noprofile
              Parent pid 8553, child pid 8554
              Child process initialized
              [...]

Templates         top

       In /usr/share/doc/firejail there are two templates to write new
       profiles.
              profile.template - for regular profiles
              redirect_alias-profile.template - for aliasing/redirecting
              profiles

Scripting         top

       Scripting commands:

       File and directory names
              File and directory names containing spaces are supported.
              The space character ' ' should not be escaped.

              Example: "blacklist ~/My Virtual Machines"

       # this is a comment

       ?CONDITIONAL: profile line
              Conditionally add profile line.

              Example: "?HAS_APPIMAGE: whitelist
              ${HOME}/special/appimage/dir"

              This example will load the whitelist profile line only if
              the --appimage option has been specified on the command
              line.

              Currently the only conditionals supported this way are
              HAS_APPIMAGE, HAS_NET, HAS_NODBUS, HAS_NOSOUND,
              HAS_PRIVATE and HAS_X11. The conditionals
              BROWSER_DISABLE_U2F and BROWSER_ALLOW_DRM can be enabled
              or disabled globally in Firejail's configuration file.

              The profile line may be any profile line that you would
              normally use in a profile except for "quiet" and "include"
              lines.

       include other.profile
              Include other.profile file.

              Example: "include /etc/firejail/disable-common.inc"

              The file name can be prefixed with a macro such as ${HOME}
              or ${CFG}.  ${HOME} is expanded as user home directory,
              and ${CFG} is expanded as Firejail system configuration
              directory - in most cases /etc/firejail or
              /usr/local/etc/firejail.

              Example: "include ${HOME}/myprofiles/profile1" will load
              "~/myprofiles/profile1" file.

              Example: "include ${CFG}/firefox.profile" will load
              "/etc/firejail/firefox.profile" file.

              The file name may also be just the name without the
              leading directory components.  In this case, first the
              user config directory (${HOME}/.config/firejail) is
              searched for the file name and if not found then the
              system configuration directory is search for the file
              name.  Note: Unlike the --profile option which takes a
              profile name without the '.profile' suffix, include must
              be given the full file name.

              Example: "include firefox.profile" will load
              "${HOME}/.config/firejail/firefox.profile" file and if it
              does not exist "${CFG}/firefox.profile" will be loaded.

              System configuration files in ${CFG} are overwritten
              during software installation.  Persistent configuration at
              system level is handled in ".local" files. For every
              profile file in ${CFG} directory, the user can create a
              corresponding .local file storing modifications to the
              persistent configuration. Persistent .local files are
              included at the start of regular profile files.

       noblacklist file_name
              If the file name matches file_name, the file will not be
              blacklisted in any blacklist commands that follow.

              Example: "noblacklist ${HOME}/.mozilla"

       nowhitelist file_name
              If the file name matches file_name, the file will not be
              whitelisted in any whitelist commands that follow.

              Example: "nowhitelist ~/.config"

       ignore Ignore command.

              Example: "ignore seccomp"
              Example: "ignore net eth0"

       quiet  Disable Firejail's output. This should be the first
              uncommented command in the profile file.

              Example: "quiet"

Filesystem         top

       These profile entries define a chroot filesystem built on top of
       the existing host filesystem. Each line describes a
       file/directory that is inaccessible (blacklist), a read-only file
       or directory (read-only), a tmpfs mounted on top of an existing
       directory (tmpfs), or mount-bind a directory or file on top of
       another directory or file (bind).  Use private to set private
       mode.  File globbing is supported, and PATH and HOME directories
       are searched, see the firejail FILE GLOBBING section for more
       details.  Examples:

       blacklist file_or_directory
              Blacklist directory or file. Examples:

              blacklist /usr/bin
              blacklist /usr/bin/gcc*
              blacklist ${PATH}/ifconfig
              blacklist ${HOME}/.ssh

       blacklist-nolog file_or_directory
              When --tracelog flag is set, blacklisting generates syslog
              messages if the sandbox tries to access the file or
              directory.  blacklist-nolog command disables syslog
              messages for this particular file or directory. Examples:

              blacklist-nolog /usr/bin
              blacklist-nolog /usr/bin/gcc*

       bind directory1,directory2
              Mount-bind directory1 on top of directory2. This option is
              only available when running as root.

       bind file1,file2
              Mount-bind file1 on top of file2. This option is only
              available when running as root.

       disable-mnt
              Disable /mnt, /media, /run/mount and /run/media access.

       keep-dev-shm
              /dev/shm directory is untouched (even with private-dev).

       keep-var-tmp
              /var/tmp directory is untouched.

       mkdir directory
              Create a directory in user home, under /tmp, or under
              /run/user/<UID> before the sandbox is started.  The
              directory is created if it doesn't already exist.

              Use this command for whitelisted directories you need to
              preserve when the sandbox is closed. Without it, the
              application will create the directory, and the directory
              will be deleted when the sandbox is closed. Subdirectories
              are recursively created. Example from firefox profile:

              mkdir ~/.mozilla
              whitelist ~/.mozilla
              mkdir ~/.cache/mozilla/firefox
              whitelist ~/.cache/mozilla/firefox

              For files in /run/user/<PID> use ${RUNUSER} macro:

              mkdir ${RUNUSER}/firejail-testing

       mkfile file
              Similar to mkdir, this command creates an empty file in
              user home, or /tmp, or under /run/user/<UID> before the
              sandbox is started. The file is created if it doesn't
              already exist.

       noexec file_or_directory
              Remount the file or the directory noexec, nodev and
              nosuid.

       private
              Mount new /root and /home/user directories in temporary
              filesystems. All modifications are discarded when the
              sandbox is closed.

       private directory
              Use directory as user home.

       private-bin file,file
              Build a new /bin in a temporary filesystem, and copy the
              programs in the list.  The files in the list must be
              expressed as relative to the /bin, /sbin, /usr/bin,
              /usr/sbin, or /usr/local/bin directories.  The same
              directory is also bind-mounted over /sbin, /usr/bin and
              /usr/sbin.

       private-cache
              Mount an empty temporary filesystem on top of the .cache
              directory in user home. All modifications are discarded
              when the sandbox is closed.

       private-cwd
              Set working directory inside jail to the home directory,
              and failing that, the root directory.

       private-cwd directory
              Set working directory inside the jail.

       private-dev
              Create a new /dev directory. Only disc, dri, dvb, hidraw,
              null, full, zero, tty, pts, ptmx, random, snd, urandom,
              video, log, shm and usb devices are available.  Use the
              options no3d, nodvd, nosound, notv, nou2f and novideo for
              additional restrictions.

       private-etc file,directory
              Build a new /etc in a temporary filesystem, and copy the
              files and directories in the list.  The files and
              directories in the list must be expressed as relative to
              the /etc directory.  All modifications are discarded when
              the sandbox is closed.

       private-home file,directory
              Build a new user home in a temporary filesystem, and copy
              the files and directories in the list in the new home.
              The files and directories in the list must be expressed as
              relative to the current user's home directory.  All
              modifications are discarded when the sandbox is closed.

       private-lib file,directory
              Build a new /lib directory and bring in the libraries
              required by the application to run.  The files and
              directories in the list must be expressed as relative to
              the /lib directory.  This feature is still under
              development, see man 1 firejail for some examples.

       private-opt file,directory
              Build a new /opt in a temporary filesystem, and copy the
              files and directories in the list.  The files and
              directories in the list must be expressed as relative to
              the /opt directory.  All modifications are discarded when
              the sandbox is closed.

       private-srv file,directory
              Build a new /srv in a temporary filesystem, and copy the
              files and directories in the list.  The files and
              directories in the list must be expressed as relative to
              the /srv directory.  All modifications are discarded when
              the sandbox is closed.

       private-tmp
              Mount an empty temporary filesystem on top of /tmp
              directory whitelisting /tmp/.X11-unix.

       read-only file_or_directory
              Make directory or file read-only.

       read-write file_or_directory
              Make directory or file read-write.

       tmpfs directory
              Mount an empty tmpfs filesystem on top of directory. This
              option is available only when running the sandbox as root.

       tracelog
              Blacklist violations logged to syslog.

       whitelist file_or_directory
              Whitelist directory or file. A temporary file system is
              mounted on the top directory, and the whitelisted files
              are mount-binded inside. Modifications to whitelisted
              files are persistent, everything else is discarded when
              the sandbox is closed. The top directory could be user
              home, /dev, /etc, /media, /mnt, /opt, /srv, /sys/module,
              /usr/share, /var, and /tmp.

              Symbolic link handling: with the exception of user home,
              both the link and the real file should be in the same top
              directory. For user home, both the link and the real file
              should be owned by the user.

       writable-etc
              Mount /etc directory read-write.

       writable-run-user
              Disable the default blacklisting of run/user/$UID/systemd
              and /run/user/$UID/gnupg.

       writable-var
              Mount /var directory read-write.

       writable-var-log
              Use the real /var/log directory, not a clone. By default,
              a tmpfs is mounted on top of /var/log directory, and a
              skeleton filesystem is created based on the original
              /var/log.

Security filters         top

       The following security filters are currently implemented:

       allow-debuggers
              Allow tools such as strace and gdb inside the sandbox by
              whitelisting system calls ptrace and process_vm_readv.

       caps   Enable default Linux capabilities filter.

       caps.drop capability,capability,capability
              Blacklist given Linux capabilities.

       caps.drop all
              Blacklist all Linux capabilities.

       caps.keep capability,capability,capability
              Whitelist given Linux capabilities.

       memory-deny-write-execute
              Install a seccomp filter to block attempts to create
              memory mappings that are both writable and executable, to
              change mappings to be executable or to create executable
              shared memory.

       nonewprivs
              Sets the NO_NEW_PRIVS prctl.  This ensures that child
              processes cannot acquire new privileges using execve(2);
              in particular, this means that calling a suid binary (or
              one with file capabilities) does not result in an increase
              of privilege.

       noroot Use this command  to enable an user namespace. The
              namespace has only one user, the current user.  There is
              no root account (uid 0) defined in the namespace.

       protocol protocol1,protocol2,protocol3
              Enable protocol filter. The filter is based on seccomp and
              checks the first argument to socket system call.
              Recognized values: unix, inet, inet6, netlink, packet and
              bluetooth.

       seccomp
              Enable seccomp filter and blacklist the syscalls in the
              default list. See man 1 firejail for more details.

       seccomp.32
              Enable seccomp filter and blacklist the syscalls in the
              default list for 32 bit system calls on a 64 bit
              architecture system.

       seccomp syscall,syscall,syscall
              Enable seccomp filter and blacklist the system calls in
              the list on top of default seccomp filter.

       seccomp.32 syscall,syscall,syscall
              Enable seccomp filter and blacklist the system calls in
              the list on top of default seccomp filter for 32 bit
              system calls on a 64 bit architecture system.

       seccomp.block-secondary
              Enable seccomp filter and filter system call architectures
              so that only the native architecture is allowed.

       seccomp.drop syscall,syscall,syscall
              Enable seccomp filter and blacklist the system calls in
              the list.

       seccomp.32.drop syscall,syscall,syscall
              Enable seccomp filter and blacklist the system calls in
              the list for 32 bit system calls on a 64 bit architecture
              system.

       seccomp.keep syscall,syscall,syscall
              Enable seccomp filter and whitelist the system calls in
              the list.

       seccomp.32.keep syscall,syscall,syscall
              Enable seccomp filter and whitelist the system calls in
              the list for 32 bit system calls on a 64 bit architecture
              system.

       seccomp-error-action kill | log | ERRNO
              Return a different error instead of EPERM to the process,
              kill it when an attempt is made to call a blocked system
              call, or allow but log the attempt.

       x11    Enable X11 sandboxing.

       x11 none
              Blacklist /tmp/.X11-unix directory, ${HOME}/.Xauthority
              and file specified in ${XAUTHORITY} environment variable.
              Remove DISPLAY and XAUTHORITY environment variables.  Stop
              with error message if X11 abstract socket will be
              accessible in jail.

       x11 xephyr
              Enable X11 sandboxing with Xephyr server.

       x11 xorg
              Enable X11 sandboxing with X11 security extension.

       x11 xpra
              Enable X11 sandboxing with Xpra server.

       x11 xvfb
              Enable X11 sandboxing with Xvfb server.

       xephyr-screen WIDTHxHEIGHT
              Set screen size for x11 xephyr. This command should be
              included in the profile file before x11 xephyr command.

              Example:

              xephyr-screen 640x480
              x11 xephyr

DBus filtering         top

       Access to the session and system DBus UNIX sockets can be
       allowed, filtered or disabled. To disable the abstract sockets
       (and force applications to use the filtered UNIX socket) you
       would need to request a new network namespace using --net
       command. Another option is to remove unix from the --protocol
       set.

       Filtering requires installing the xdg-dbus-proxy utility. Filter
       rules can be specified for well-known DBus names, but they are
       also propagated to the owning unique name, too. The permissions
       are "sticky" and are kept even if the corresponding well-known
       name is released (however, applications rarely release well-known
       names in practice). Names may have a .* suffix to match all names
       underneath them, including themselves (e.g. "foo.bar.*" matches
       "foo.bar", "foo.bar.baz" and "foo.bar.baz.quux", but not
       "foobar"). For more information, see xdg-dbus-proxy(1).

       Examples:

              object exposed at the path /org/freedesktop/Notifications
              by the client owning the bus name
              org.freedesktop.Notifications on the system DBus.

       dbus-user filter
              Enable filtered access to the session DBus. Filters can be

              and the user wants to disable notifications, this can be
              achieved by putting the below in a local override file:
              [...]
              ignore dbus-user.talk org.freedesktop.Notifications
              [...]

Resource limits, CPU affinity, Control Groups         top

       These profile entries define the limits on system resources
       (rlimits) for the processes inside the sandbox.  The limits can
       be modified inside the sandbox using the regular ulimit command.
       cpu command configures the CPU cores available, and cgroup
       command place the sandbox in an existing control group.

       Examples:

       cgroup /sys/fs/cgroup/g1/tasks
              The sandbox is placed in g1 control group.

       cpu 0,1,2
              Use only CPU cores 0, 1 and 2.

       nice -5
              Set a nice value of -5 to all processes running inside the
              sandbox.

       rlimit-as 123456789012
              Set the maximum size of the process's virtual memory to
              123456789012 bytes.

       rlimit-cpu 123
              Set the maximum CPU time in seconds.

       rlimit-fsize 1024
              Set the maximum file size that can be created by a process
              to 1024 bytes.

       rlimit-nproc 1000
              Set the maximum number of processes that can be created
              for the real user ID of the calling process to 1000.

       rlimit-nofile 500
              Set the maximum number of files that can be opened by a
              process to 500.

       rlimit-sigpending 200
              Set the maximum number of processes that can be created
              for the real user ID of the calling process to 200.

       timeout hh:mm:ss
              Kill the sandbox automatically after the time has elapsed.
              The time is specified in hours/minutes/seconds format.

User Environment         top

       allusers
              All user home directories are visible inside the sandbox.
              By default, only current user home directory is visible.

       env name=value
              Set environment variable. Examples:

              env LD_LIBRARY_PATH=/opt/test/lib
              env CFLAGS="-W -Wall -Werror"

       ipc-namespace
              Enable IPC namespace.

Networking         top

       Networking features available in profile files.

       defaultgw address
              Use this address as default gateway in the new network
              namespace.

       dns address
              Set a DNS server for the sandbox. Up to three DNS servers
              can be defined.

       hostname name
              Set a hostname for the sandbox.

       hosts-file file
              Use file as /etc/hosts.

       ip address
              Assign IP addresses to the last network interface defined
              by a net command. A default gateway is assigned by
              default.

              Example:
              net eth0
              ip 10.10.20.56

       ip none
              No IP address and no default gateway are configured for
              the last interface defined by a net command. Use this
              option in case you intend to start an external DHCP client
              in the sandbox.

              Example:
              net eth0
              ip none

       ip dhcp
              Acquire an IP address and default gateway for the last
              interface defined by a net command, as well as set the DNS
              servers according to the DHCP response.  This command
              requires the ISC dhclient DHCP client to be installed and
              will start it automatically inside the sandbox.

              Example:
              net br0
              ip dhcp

              This command should not be used in conjunction with the
              dns command if the DHCP server is set to configure DNS
              servers for the clients, because the manually specified
              DNS servers will be overwritten.

              The DHCP client will NOT release the DHCP lease when the
              sandbox terminates.  If your DHCP server requires leases
              to be explicitly released, consider running a DHCP client
              and releasing the lease manually in conjunction with the
              net none command.

       ip6 address
              Assign IPv6 addresses to the last network interface
              defined by a net command.

              Example:
              net eth0
              ip6 2001:0db8:0:f101::1/64

       ip6 dhcp
              Acquire an IPv6 address and default gateway for the last
              interface defined by a net command, as well as set the DNS
              servers according to the DHCP response.  This command
              requires the ISC dhclient DHCP client to be installed and
              will start it automatically inside the sandbox.

              Example:
              net br0
              ip6 dhcp

              This command should not be used in conjunction with the
              dns command if the DHCP server is set to configure DNS
              servers for the clients, because the manually specified
              DNS servers will be overwritten.

              The DHCP client will NOT release the DHCP lease when the
              sandbox terminates.  If your DHCP server requires leases
              to be explicitly released, consider running a DHCP client
              and releasing the lease manually.

       iprange address,address
              Assign  an  IP address in the provided range to the last
              network interface defined by  a  net command.  A  default
              gateway  is assigned by default.

              Example:

              net eth0
              iprange 192.168.1.150,192.168.1.160

       mac address
              Assign MAC addresses to the last network interface defined
              by a net command.

       machine-id
              Spoof id number in /etc/machine-id file - a new random id
              is generated inside the sandbox.

       mtu number
              Assign a MTU value to the last network interface defined
              by a net command.

       net bridge_interface
              Enable a new network namespace and connect it to this
              bridge interface.  Unless specified with option --ip and
              --defaultgw, an IP address and a default gateway will be
              assigned automatically to the sandbox. The IP address is
              verified using ARP before assignment. The address
              configured as default gateway is the bridge device IP
              address. Up to four --net bridge devices can be defined.
              Mixing bridge and macvlan devices is allowed.

       net ethernet_interface|wireless_interface
              Enable a new network namespace and connect it to this
              ethernet interface using the standard Linux macvlan or
              ipvlan driver. Unless specified with option --ip and
              --defaultgw, an IP address and a default gateway will be
              assigned automatically to the sandbox. The IP address is
              verified using ARP before assignment. The address
              configured as default gateway is the default gateway of
              the host. Up to four --net devices can be defined. Mixing
              bridge and macvlan devices is allowed.

       net none
              Enable a new, unconnected network namespace. The only
              interface available in the new namespace is a new loopback
              interface (lo).  Use this option to deny network access to
              programs that don't really need network access.

       net tap_interface
              Enable a new network namespace and connect it to this
              ethernet tap interface using the standard Linux macvlan
              driver.  If the tap interface is not configured, the
              sandbox will not try to configure the interface inside the
              sandbox.  Please use ip, netmask and defaultgw to specify
              the configuration.

       netfilter
              If a new network namespace is created, enabled default
              network filter.

       netfilter filename
              If a new network namespace is created, enabled the network
              filter in filename.

       netmask address
              Use this option when you want to assign an IP address in a
              new namespace and the parent interface specified by --net
              is not configured. An IP address and a default gateway
              address also have to be added.

       netns namespace
              Run the program in a named, persistent network namespace.
              These can be created and configured using "ip netns".

       veth-name name
              Use this name for the interface connected to the bridge
              for --net=bridge_interface commands, instead of the
              default one.

Other         top

       deterministic-exit-code
              Always exit firejail with the first child's exit status.
              The default behavior is to use the exit status of the
              final child to exit, which can be nondeterministic.

       join-or-start sandboxname
              Join the sandbox identified by name or start a new one.
              Same as "firejail --join=sandboxname" command if sandbox
              with specified name exists, otherwise same as "name
              sandboxname".
