It has support for IPv4, IPv6 firewall settings and for ethernet bridges and a separation of runtime and permanent configuration options. It also provides an interface for services or applications to add ip*tables and ebtables rules directly. Development ----------- To check out the source repository, you can use: ```sh git clone https://github.com/firewalld/firewalld.git ``` This will create a local copy of the repository. The contributor code of conduct can be found in [CODE_OF_CONDUCT.md](CODE_OF_CONDUCT.md) Language Translations --------------------- Firewalld uses GNU gettext for localization support. Translations can be done using [Fedora's Weblate instance][1]. Translations are periodically merged into the main firewalld repository. [1]: https://translate.stg.fedoraproject.org/projects/firewalld/ Dependencies ------------ These are the runtime dependencies: ``` linux >= 5.3 python3-dbus python3-gobject python3-nftables >= 0.9.4 ``` **Note**: python2 is _not_ supported. Optional Dependencies --------------------- These dependencies may enhance firewalld's functionality, but they are not required. ``` ebtables ipset iptables polkit python3-capng (libcap-ng-python3) ``` Working With The Source Repository ---------------------------------- In addition to the runtime dependencies some others are needed to build from source: ``` desktop-file-utils: /usr/bin/desktop-file-install gettext intltool glib2: /usr/bin/glib-compile-schemas glib2-devel: /usr/share/aclocal/gsettings.m4 systemd-units ``` To be able to create man pages and documentation from docbook files: ``` docbook-style-xsl libxslt ``` Use the usual autoconf/automake incantation to generate makefiles ```sh ./autogen.sh ./configure ``` You can use a specific python interpreter by passing the PYTHON variable. This is also used by the testsuite. ```sh ./configure PYTHON=/path/to/python3 ``` Use ```sh make ``` to create the documentation and to update the po files. Use ```sh make check ``` to run the testsuite. Tests are run inside network namespaces and do not interfere with the host's running firewalld. They can also be run in parallel by passing flags to autotest. ```sh make check TESTSUITEFLAGS="-j4" ``` The testsuite also uses keywords to allow running a subset of tests that exercise a specific area. For example: ```sh make check TESTSUITEFLAGS="-k rich -j4" ``` Output: ```sh 24: rich rules audit ok 25: rich rules priority ok 26: rich rules bad ok 53: rich rules audit ok 23: rich rules good ok 55: rich rules bad ok 74: remove forward-port after reload ok ``` You can get a list of tests and keywords ```sh make -C src/tests check TESTSUITEFLAGS="-l" ``` Or just the keywords ```sh make -C src/tests check TESTSUITEFLAGS="-l" \ |awk '/^[[:space:]]*[[:digit:]]+/{getline; print $0}' \ |tr ' ' '\n' |sort |uniq ``` There are integration tests. Currently this includes NetworkManager. These may be _destructive_ to the host. Run them in a disposable VM or container. ```sh make check-integration ``` There is also a check-container target that will run the testsuite inside various podman/docker containers. This is useful for coverage of multiple distributions. It also runs tests that may be destructive to the host such as integration tests. ```sh make check-container TESTSUITEFLAGS="-j4" ``` OCI Container Image ------------------- As part of the `dist` build target an OCI container image is generated. This is distributed alongside the normal release tarball. It can be used to run firewalld from a container. The containerized firewalld will _not_ integrate with the host (e.g. podman, libvirt, NetworkManager). To manually load the container image into your environment: ```sh podman load -i .../path/to/firewalld-oci-<ver>.tar ``` To fetch the image from quay.io: ```sh podman pull quay.io/firewalld/firewalld:<ver> ``` where `<ver>` is optional, the latest version will be used if omitted. To start the daemon/container: ```sh podman run -d --network host --privileged \ --name my-firewalld firewalld ``` Firewalld's configuration will live inside the container. Therefore users may want to occasionally `podman commit` the image. Using firewalld's CLI should be done via podman exec after the daemon/container has been started: ```sh podman exec my-firewalld firewall-cmd ... ``` ### Container Integration with Host The same container image can be used to integrate with the host's running NetworkManager, podman, libvirt, etc. This requires the host to have a dbus policy for firewalld. A dbus policy can be obtained from the firewalld source code tree at location `config/FirewallD.conf`. ```sh cp config/FirewallD.conf /usr/share/dbus-1/system.d/FirewallD.conf ``` Once the dbus policy is in place the container could be started as such: ```sh podman run -d -v /run/dbus/system_bus_socket:/run/dbus/system_bus_socket \ --network host --privileged \ --name my-firewalld firewalld \ firewalld --nofork --nopid ``` The only addition are: volume mount, explicit CMD. The some approach can be use to store firewalld's configuration files on the host. ```sh podman run -d -v /run/dbus/system_bus_socket:/run/dbus/system_bus_socket \ -v /etc/firewalld:/etc/firewalld \ --network host --privileged \ --name my-firewalld firewalld \ firewalld --nofork --nopid ``` RPM package ----------- For Fedora and RHEL based distributions, there is a spec file in the source repo named firewalld.spec. This should be usable for Fedora versions >= 16 and RHEL >= 7.
