README for firewalld
====================

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. 


Development
-----------
To check out the source repository, you can use:

  git clone https://github.com/firewalld/firewalld.git

This will create a local copy of the repository.

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.

Working With The Source Repository
----------------------------------
Install the following requirements or packages:

  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
  iptables
  ebtables
  ipset

For use with Python 3:

  python3-dbus
  python3-slip-dbus
  python3-decorator
  python3-gobject
  python3-nftables (nftables >= 0.9.3)

For use with Python 2:

  dbus-python
  python-slip-dbus (http://fedorahosted.org/python-slip)
  python-decorator
  pygobject3-base (non-cairo parts of pygobject3)
  python-nftables (nftables >= 0.9.3)

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
  ./configure

You can use a specific python interpreter by passing the PYTHON variable. This
is also used by the testsuite.

  ./configure PYTHON=/path/to/python3

Use

  make

to create the documentation and to update the po files.

Use

  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.

  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"
   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

  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 |uniq

There are integration tests. Currently this includes NetworkManager. These may
be _destructive_ to the host. Run them in a disposable VM or container.

    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.

  make check-container TESTSUITEFLAGS="-j4"

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.
