In conjunction with src.git, ports.git, core.git and plugins.git they create sets, packages and images for the OPNsense project.
Install FreeBSD 13.2-RELEASE for amd64 on a machine with at least 25GB of hard disk (UFS works better than ZFS) and at least 4GB of RAM to successfully build all standard images. All tasks require a root user. Do the following to grab the repositories (overwriting standard ports and src):
# pkg install git
# cd /usr
# git clone https://github.com/biptec/opnsense-tools tools
# cd tools
# make update
Note that the OPNsense repositories can also be setup in a non-/usr directory by setting ROOTDIR. For example:
# mkdir -p /tmp/opnsense
# cd /tmp/opnsense
# git clone https://github.com/biptec/opnsense-tools tools
# cd tools
# env ROOTDIR=/tmp/opnsense make update
# make dvd
If successful, a dvd image can be found under:
# make print-IMAGESDIR
The build is broken down into individual stages: base, kernel, ports, plugins and core can be built separately and repeatedly without affecting the other stages. All stages can be reinvoked and continue building without cleaning the previous progress. A final stage assembles all five stages into a target image.
All build steps are invoked via make(1):
# make step OPTION="value"
Available early build options are:
- SETTINGS: the name of the requested local configuration
- CONFIGDIR: read configuration from other directory and override SETTINGS
Available build options are:
- ABI: a custom ABI (defaults to SETTINGS)
- ADDITIONS: a list of packages/plugins to add to images
- ARCH: the target architecture if not native
- COMSPEED: serial speed, e.g. "115200" (default)
- DEBUG: build a debug kernel with additional object information
- DEVICE: loads device-specific modifications, e.g. "A10" (default)
- KERNEL: the kernel config to use, e.g. SMP (default)
- MIRRORS: a list of mirrors to prefetch sets from
- NAME: "OPNsense" (default)
- PRIVKEY: the private key for signing sets
- PUBKEY: the public key for signing sets
- SUFFIX: the suffix of top package name (default is empty)
- TYPE: the base name of the top package to be installed
- UEFI: use amd64 hybrid images for said images, e.g. "vga vm"
- VERSION: a version tag (if applicable)
- ZFS: ZFS pool name to create for VM images, e.g. "zpool"
- VAGRANT: creating a vagrant user in the image
The configuration file is required at "CONFIGDIR/build.conf". Its contents can be modified to adapt a non-standard build environment and to avoid excessive Makefile arguments.
A local override exists as "CONFIGDIR/build.conf.local" and is parsed first to allow more flexible overrides. Use with care.
Kernel, base, packages and release sets are stored under:
# make print-SETSDIR
All final images are stored under:
# make print-IMAGESDIR
All final vagrant boxes are stored under:
# make print-VAGRANTBOXES
Build the userland binaries, bootloader and administrative files:
# make base
Build the kernel and loadable kernel modules:
# make kernel
Build all the third-party ports:
# make ports
Build additional plugins if needed:
# make plugins
Wrap up our core as a package:
# make core
A dvd live image is created using:
# make dvd
A serial memstick live image is created using:
# make serial
A vga memstick live image is created using:
# make vga
A flash card full disk image is created using:
# make nano
A virtual machine full disk image is created using:
# make vm
A vagrant box is created using:
# make vagrantbox
A special embedded device image based on vm variety:
# make factory
Release sets can be built as follows although the result is an unpredictable set of images depending on the previous build states:
# make release
However, the release target is necessary for the following target which includes sanity checks, proper clearing of the images directory and core package version alignment:
# make distribution
This feature is currently experimental and requires installation of packages for cross building / user mode emulation and additional boot files to be installed as prompted by the build system.
A cross-build on the operating system sources is executed by specifying the target architecture and custom kernel:
# make base kernel DEVICE=BANANAPI
In order to speed up building of using an emulated packages build, the xtools set can be created like so:
# make xtools DEVICE=BANANAPI
The xtools set is then used during the packages build similar to the distfiles set.
# make packages DEVICE=BANANAPI
The final image is built using:
# make arm-<size> DEVICE=BANANAPI
Currently available device are: BANANAPI and RPI2.
Device-specific settings can be found and added in the device/ directory. Of special interest are hooks into the build process for required non-default settings for image builds. The .conf files are shell scripts that can define hooks in the form of e.g.:
serial_hook()
{
# ${1} is the target file system root
touch ${1}/my_custom_file
}
These hooks are available for all image types, namely dvd, nano, serial, vga and vm. Device-specific hooks are loaded after config-specific hooks and both of them can coexist in a given build.
Updating all or individual repositories can be done as follows:
# make update[-<repo1>[,...]] [VERSION=git.tag]
Available update options are: core, plugins, ports, portsref, src, tools
VERSION can be used to update to the matching git tag instead of HEAD.
Before building images, you can run the regression tests to check the integrity of your core.git modifications plus generate output for the style checker:
# make test
To check the binary packages from ports against the upstream vulnerability database run the following:
# make audit
Package sets ready for web server deployment are automatically generated and modified by ports, plugins and core steps. The build automatically caches temporary build dependencies to avoid spurious rebuilds. These packages are later discarded to provide a slim runtime set only.
If signing keys are available, the packages set will be signed twice, first embedded into repository metadata (inside) and then again as a flat file (outside) to ensure integrity.
For faster ports building it may be of use to cache all distribution files before running the actual build:
# make distfiles
For targeted rebuilding of already built packages the following works:
# make ports-<packagename>[,...]
# make plugins-<packagename>[,...]
# make core-<packagename>[,...]
Please note that reissuing ports builds will clear plugins and core progress. However, following option apply to PORTSENV:
- BATCH=no Developer mode with shell after each build failure
- DEPEND=no Do not tamper with plugins or core packages
- PRUNE=no Do not check ports integrity prior to rebuild
The defaults for these ports options are set to "yes". A sample invoke is as follows:
# make ports-curl PORTSENV="DEPEND=no PRUNE=no"
Both ports and plugins builds allow to override the current list derived from their respective configuration files, i.e.:
# make ports PORTSLIST="security/openssl"
# make plugins PLUGINSLIST="devel/debug"
Compiled sets can be prefetched from a mirror if they exist, while removing any previously available set:
# make prefetch-<option>[,...] [VERSION=<full_version>]
If another build configuration is used locally that is compatible, the sets can be cloned from there as well:
# make clone-<option>[,...] TO=<major_version>
Available prefetch or clone options are:
- base: select matching base set
- distfiles: select matching distfiles set (clone only)
- kernel: select matching kernel set
- packages: select matching packages set
Signing for all sets can be redone or applied to a previous run that did not sign by invoking:
# make sign-base,kernel,packages
A verification of all available set signatures is done via:
# make verify
Nano images can be adjusted in size using an argument as follows:
# make nano-<size>
Virtual machine images come in varying disk formats and sizes. For this reason they are not included in our binary releases. The default format is vmdk with 20G and 1G swap. If you want to change that you can manually alter the invoke using:
# make vm-<format>[,<size>[,<swap>[,<extras>]]]
Available virtual machine disk formats are:
- qcow: Qemu, KVM (legacy format)
- qcow2: Qemu, KVM (not backwards-compatible)
- raw: Unformatted (sector by sector)
- vhd: VirtualPC, Hyper-V, Xen (dynamic size)
- vhdf: Azure, VirtualPC, Hyper-V, Xen (fixed size)
- vmdk: VMWare, VirtualBox (dynamic size)
The swap argument is either its size or set to "off" to disable.
The extras argument can be any extras.conf hook in case the default "vm" hook is not desirable.
Vagrant box is created with the same parameters as the virtual machine image, but instead of the vm prefix, you need to specify vagrantbox:
# make vagrantbox-<format>[,<size>[,<swap>[,<extras>]]]
Available virtual machines:
- vmdk: VMWare
An example of creating a vagrant box with additional packages and plugins:
# make vagrantbox-vmdk,5G,never DEVICE=ARM64 ADDITIONS="git emacs-nox open-vm-tools-nox11 zsh ohmyzsh rsync os-firewall os-frr"
A couple of build machine cleanup helpers are available via the clean script:
# make clean-<option>[,...]
Available clean options are:
- arm: remove arm image
- base: remove base set
- distfiles: remove distfiles set
- dvd: remove dvd image
- core: remove core from packages set
- images: remove all images
- kernel: remove kernel set
- logs: remove all logs
- nano: remove nano image
- obj: remove all object directories
- packages: remove packages set
- plugins: remove plugins from packages set
- ports: alias for "packages" option
- release: remove release set
- serial: remove serial image
- sets: remove all sets
- src: reset kernel/base build directory
- stage: reset main staging area
- vga: remove vga image
- vm: remove vm image
- xtools: remove xtools set
The ports tree has a few of our modifications and is sometimes a bit ahead of FreeBSD. In order to keep the local changes, a skimming script is used to review and copy upstream changes:
# make skim[-<option>]
Available options are:
- used: review and copy upstream changes
- unused: copy unused upstream changes
- (none): all of the above
In case base files changed, the base package list and obsoleted files need to be regenerated. This is done using:
# make rebase
Shall any debugging be needed inside the build jail, the following command will use chroot(8) to enter the active build jail:
# make chroot[-<subdir>]
There's also the posh way to boot a final image using bhyve(8):
# make boot-<image>
Please note that login is only possible via the Nano and Serial images.
Booting VM images will not work for types other than "raw".
A ports tree in a running OPNsense can be used to build packages not published on the mirrors. To generate the make.conf contents for standalone use on the host use:
# make make.conf
Normally the build scripts will pick up version numbers based on commit tags or given version tags or a date-type string. Should it not fit your needs, you can change the name using:
# make rename-<set>[,<another_set>] VERSION=<new_name>
The available targets are: base, distfiles, dvd, kernel, nano, packages, serial, vga and vm.
The current state of the associated build repositories checked out on the system can be printed using:
# make info
Repositories that have signing keys can show the current fingerprint using:
# make fingerprint
Last but not least, in case build variables needs to be inspected, they can be printed selectively using:
# make print-<variable1>[,<variable2>]
Images are compressed using bzip2(1) for distribution. This can be invoked manually using:
# make compress-<image1>[,<image2>]
A fully contained nightly build for the system is invoked using:
# make nightly
To allow the nightly build to build both release and development packages use:
# make nightly EXTRABRANCH=master
Nightly builds are the only builds that write and archive logs under:
# make print-LOGSDIR
with ./latest containing the last nightly build run. Older logs are archived and available for a whole week for retrospective analysis.
To push sets and images to a remote location use the upload target:
# make upload-<set>[,...]
To pull sets and images from a remote location use the download target:
# make download-<set>[,...]
Logs can be downloaded as well for local inspection. Note that download like prefetch will purge all locally existing targets. Use SERVER to specify the remote end, e.g. SERVER=user@does.not.exist
Additionally, UPLOADDIR can be used to specify a remote location. At this point only "logs" upload cleares and creates directories on the fly.
If you want to script interactive prompts you may use the confirm target to operate yes or no questions before an action:
# make info confirm dvd
To add arbitrary plugins from an external location into an image you can use the following:
# make custom-<image> ADDITIONS="an-existing-plugin path/to/extra/plugin"
Last but not least, a rebuild of OPNsense core and plugins on package sets is invoked using:
# make hotfix[-<step>]
It will flush all previous packages except for ports, rebuild core and plugins and sign the sets if enabled. It can also explicity set "core" or "plugins".
