firewalld provides a dynamically managed firewall with support for network or firewall zones to define the trust level of network connections or interfaces. 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.
To check out the source repository, you can use:
git clone https://github.com/firewalld/firewalld.gitThis will create a local copy of the repository.
The contributor code of conduct can be found in CODE_OF_CONDUCT.md
Firewalld uses GNU gettext for localization support. Translations can be done using Fedora's Weblate instance. Translations are periodically merged into the main firewalld repository.
These are the runtime dependencies:
linux >= 5.3
python >= 3.7
python3-dbus
python3-gobject
python3-nftables >= 0.9.4
Note: python2 is not supported.
These dependencies may enhance firewalld's functionality, but they are not required.
ebtables
ipset
iptables
polkit
python3-capng (libcap-ng-python3)
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
pytest
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
./autogen.sh
./configureYou can use a specific python interpreter by passing the PYTHON variable. This is also used by the testsuite.
./configure PYTHON=/path/to/python3Use
maketo create the documentation and to update the po files.
Use
make checkto 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.
make check TESTSUITEFLAGS="-j4"The testsuite also uses keywords to allow running a subset of tests that exercise a specific area. For example:
make check TESTSUITEFLAGS="-k rich -j4"Output:
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 okYou can get a list of tests and keywords
make -C src/tests check TESTSUITEFLAGS="-l"Or just the keywords
make -C src/tests check TESTSUITEFLAGS="-l" \
|awk '/^[[:space:]]*[[:digit:]]+/{getline; print $0}' \
|tr ' ' '\n' |sort |uniqThere are integration tests. Currently this includes NetworkManager. These may be destructive to the host. Run them in a disposable VM or container.
make check-integrationThere 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.
make check-container TESTSUITEFLAGS="-j4"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:
podman load -i .../path/to/firewalld-oci-<ver>.tarTo fetch the image from quay.io:
podman pull quay.io/firewalld/firewalld:<ver>where <ver> is optional, the latest version will be used if omitted.
To start the daemon/container:
podman run -d --network host --privileged \
--name my-firewalld firewalldFirewalld'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:
podman exec my-firewalld firewall-cmd ...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.
cp config/FirewallD.conf /usr/share/dbus-1/system.d/FirewallD.confOnce the dbus policy is in place the container could be started as such:
podman run -d -v /run/dbus/system_bus_socket:/run/dbus/system_bus_socket \
--network host --privileged \
--name my-firewalld firewalld \
firewalld --nofork --nopidThe only addition are: volume mount, explicit CMD.
The some approach can be use to store firewalld's configuration files on the host.
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 --nopidFor 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.
