When selecting multiple source or targets, a cartesian product is created for all combinations (one defined rule turns into multiple actual rules).
In order to make this possible, we needed to refactor the base rule parsing. our generic `reader()` multiplies rules, which it already did for interfaces and ipprotocol.
When feeding lists to `pf(4)` a similar action would be performed.
The `convertAddress()` method has been renamed to `legacyMoveAddressFields()` as it now only remaps field structures into flattened fields, without validating their contents.
This is needed so we can split source/destinations without caring about their validity (yet), `mapAddressInfo()` is added next which contains the same logic as previously in `convertAddress()` but executed after splitting the fields.
The "Automation" module is more or less a reference implementation to show how the backend handles these now, 22fd0bf8763e14a5e1e7694853af0893dae585b7 is required for this to work.
All changes should be backwards compatible, but deliver a slightly different ruleset in some cases (when multiple entries are already used), e.g. the rule below would be split into two on our end now:
397a3dcdce/src/etc/inc/filter.lib.inc (L231-L237)
`pfctl -sr` already showed two before our change.
OPNsense GUI and system management
The OPNsense project invites developers to start contributing to the code base. For your own purposes or – even better – to join us in creating the best open source firewall available.
The build process has been designed to make it easy for anyone to build and write code. The main outline of the new codebase is available at:
https://docs.opnsense.org/development/architecture.html
Our aim is to gradually evolve to a new codebase instead of using a big bang approach into something new.
Build tools
To create working software like OPNsense you need the sources and the tools to build it. The build tools for OPNsense are freely available.
Notes on how to build OPNsense can be found in the tools repository:
https://github.com/opnsense/tools
Contribute
You can contribute to the project in many ways, e.g. testing functionality, sending in bug reports or creating pull requests directly via GitHub. Any help is always very welcome!
You can learn more about contributing on CONTRIBUTING.md.

Every contribution made to the project must be licensed under the same conditions in order to keep OPNsense truly free and accessible for everybody.
Makefile targets
The repository offers a couple of targets that either tie into tools.git build processes or are aimed at fast development.
make package
A package of the current state of the repository can be created using this target. It may require several packages to be installed. The target will try to assist in case of failure, e.g. when a missing file needs to be fetched from an external location.
Several OPTIONS exist to customise the package, e.g.:
- CORE_DEPENDS: a list of required dependencies for the package
- CORE_DEPENDS_ARCH: a list of special -required packages
- CORE_ORIGIN: sets a FreeBSD compatible package/ports origin
- CORE_COMMENT: a short description of the package
- CORE_MAINTAINER: email of the package maintainer
- CORE_WWW: web url of the package
- CORE_NAME: sets a package name
Options are passed in the following form:
# make package CORE_NAME=my_new_name
In general, options are either set to sane defaults or automatically detected at runtime.
make update
Update will pull the latest commits from the current branch from the upstream repository.
make upgrade
Upgrade will run the package build and replace the currently installed package in the system.
make collect
Fetch changes from the running system for all known files.
make lint
Run several syntax checks on the repository. This is recommended before issuing a pull request on GitHub.
make style
Run the PSR12 and PEP8 style checks on MVC PHP code and Python,
respectively.
For php code you will need to have phpcs and phpcbf installed.
You can use the package php-codesniffer on Debian/Ubuntu.
Python code will require pycodestyle.
For easier development you may want to use an OPNsense VM and install
the os-debug plugin that will offer the necessary tools.
make sweep
Run Linux Kernel cleanfile whitespace sanitiser on all files.
