The -file `data/defaults.json` hosts a JSON definition of the kernel version used -`kernel_version` and the `kernel_flavor` of the kernel which represents the -kernel's LOCAL_VERSION. Both together form the kernel version variable in the -system: - -```none -vyos@vyos:~$ uname -r -6.1.52-amd64-vyos -``` - -- Accel-PPP -- Intel NIC drivers -- Intel QAT - -Each of those modules holds a dependency on the kernel version and if you are -lucky enough to receive an ISO build error which sounds like: - -```none -I: Create initramfs if it does not exist. -Extra argument '6.1.52-amd64-vyos' -Usage: update-initramfs {-c|-d|-u} [-k version] [-v] [-b directory] -Options: - -k version Specify kernel version or 'all' - -c Create a new initramfs - -u Update an existing initramfs - -d Remove an existing initramfs - -b directory Set alternate boot directory - -v Be verbose -See update-initramfs(8) for further details. -E: config/hooks/live/17-gen_initramfs.chroot failed (exit non-zero). You should check for errors. -``` - -The most obvious reasons could be: - -- `vyos-build` repo is outdated, please `git pull` to update to the latest - release kernel version from us. -- You have your own custom kernel `*.deb` packages in the `packages` folder but - neglected to create all required out-of tree modules like Accel-PPP, Intel - QAT or Intel NIC drivers - -#### Building The Kernel - -The kernel build is quite easy, most of the required steps can be found in the -`vyos-build/packages/linux-kernel/Jenkinsfile` but we will walk you through -it. - -Clone the kernel source to `vyos-build/packages/linux-kernel/`: - -```none -$ cd vyos-build/packages/linux-kernel/ -$ git clone https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git -``` - -Check out the required kernel version - see `vyos-build/data/defaults.json` -file (example uses kernel 4.19.146): - -```none -$ cd vyos-build/packages/linux-kernel/linux -$ git checkout v4.19.146 -Checking out files: 100% (61536/61536), done. -Note: checking out 'v4.19.146'. - -You are in 'detached HEAD' state.

Example: - git checkout -b <new-branch-name> -HEAD is now at 015e94d0e37b Linux 4.19.146 -``` - -Now you can use the helper script `build-kernel.sh`, which completes all -the necessary steps: applying required patches from the -`vyos-build/packages/linux-kernel/patches` folder, copying the kernel -configuration `x86_64_vyos_defconfig` to the correct location, and building -the Debian packages. - -:::{note} -Building the kernel will take some time depending on the speed and -quantity of your CPU/cores and disk speed. Expect 20 minutes -(or even longer) on lower end hardware. -::: - -```none -(18:59) vyos_bld 412374ca36b8:/vyos/vyos-build/packages/linux-kernel [current] # ./build-kernel.sh -I: Copy Kernel config (x86_64_vyos_defconfig) to Kernel Source -I: Apply Kernel patch: /vyos/vyos-build/packages/linux-kernel/patches/kernel/0001-VyOS-Add-linkstate-IP-device-attribute.patch -patching file Documentation/networking/ip-sysctl.txt -patching file include/linux/inetdevice.h -patching file include/linux/ipv6.h -patching file include/uapi/linux/ip.h -patching file include/uapi/linux/ipv6.h -patching file net/ipv4/devinet.c -Hunk #1 succeeded at 2319 (offset 1 line). -patching file net/ipv6/addrconf.c -patching file net/ipv6/route.c -I: Apply Kernel patch: /vyos/vyos-build/packages/linux-kernel/patches/kernel/0002-VyOS-add-inotify-support-for-stackable-filesystems-o.patch -patching file fs/notify/inotify/Kconfig -patching file fs/notify/inotify/inotify_user.c -patching file fs/overlayfs/super.c -Hunk #2 succeeded at 1713 (offset 9 lines). -Hunk #3 succeeded at 1739 (offset 9 lines). -Hunk #4 succeeded at 1762 (offset 9 lines). -patching file include/linux/inotify.h -I: Apply Kernel patch: /vyos/vyos-build/packages/linux-kernel/patches/kernel/0003-RFC-builddeb-add-linux-tools-package-with-perf.patch -patching file scripts/package/builddeb -I: make x86_64_vyos_defconfig - HOSTCC scripts/basic/fixdep - HOSTCC scripts/kconfig/conf.o - YACC scripts/kconfig/zconf.tab.c - LEX scripts/kconfig/zconf.lex.c - HOSTCC scripts/kconfig/zconf.tab.o - HOSTLD scripts/kconfig/conf -# - -# configuration written to .config -# -I: Generate environment file containing Kernel variable -I: Build Debian Kernel package - UPD include/config/kernel.release -/bin/sh ./scripts/package/mkdebian -dpkg-buildpackage -r"fakeroot -u" -a$(cat debian/arch) -b -nc -uc -dpkg-buildpackage: info: source package linux-4.19.146-amd64-vyos -dpkg-buildpackage: info: source version 4.19.146-1 -dpkg-buildpackage: info: source distribution buster -dpkg-buildpackage: info: source changed by vyos_bld <christian@poessinger.com> -dpkg-buildpackage: info: host architecture amd64 -dpkg-buildpackage: warning: debian/rules is not executable; fixing that - dpkg-source --before-build . - debian/rules build -make KERNELRELEASE=4.19.146-amd64-vyos ARCH=x86 KBUILD_BUILD_VERSION=1 KBUILD_SRC= - SYSTBL arch/x86/include/generated/asm/syscalls_32.h -... -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: binaries to analyze should already be installed in their package's directory -dpkg-shlibdeps: warning: package could avoid a useless dependency if /vyos/vyos-build/packages/linux-kernel/linux/debian/toolstmp/usr/bin/trace /vyos/vyos-build/packages/linux-kernel/linux/debian/toolstmp/usr/bin/perf were not linked against libcrypto.so.1.1 (they use none of the library's symbols) -dpkg-shlibdeps: warning: package could avoid a useless dependency if /vyos/vyos-build/packages/linux-kernel/linux/debian/toolstmp/usr/bin/trace /vyos/vyos-build/packages/linux-kernel/linux/debian/toolstmp/usr/bin/perf were not linked against libcrypt.so.1 (they use none of the library's symbols) -dpkg-deb: building package 'linux-tools-4.19.146-amd64-vyos' in '../linux-tools-4.19.146-amd64-vyos_4.19.146-1_amd64.deb'. - dpkg-genbuildinfo --build=binary - dpkg-genchanges --build=binary >../linux-4.19.146-amd64-vyos_4.19.146-1_amd64.changes -dpkg-genchanges: warning: package linux-image-4.19.146-amd64-vyos-dbg in control file but not in files list -dpkg-genchanges: info: binary-only upload (no source code included) - dpkg-source --after-build . -dpkg-buildpackage: info: binary-only upload (no source included) -``` - -When complete, you will have kernel binary packages to use in your custom ISO -build.

Tabs **must not** be used. -- **XML**: Use 2 spaces per indentation level. Tabs **must not** be used. - -Use tools like VIM extensions (xmllint) to enforce correct indentation. Add this -to your `.vimrc` file: - -```none -au FileType xml setlocal equalprg=xmllint\ --format\ --recover\ -\ 2>/dev/null -``` - -Then use `gg=G` in command mode to run the linter. - -### Text generation - -Use a template processor for generating config files: - -- **Jinja2** is the default template processor for VyOS code. -- Built-in string formatting **may** be used for simple line-oriented formats - (for example, iptables rules) where every line is self-contained. -- Template processors **must** be used for structured, multi-line formats - (for example, ISC DHCPd configuration). - -### Python code - -Configuration scripts and operation mode scripts written in Python3 should -follow these guidelines: - -- Wrap lines at 80 characters.

No other function may call the `vyos.config.Config` -object directly. Limiting config reads to one function makes it easier to -modify the config syntax in the future. Additionally, this design improves -testability since you can construct an internal representation by hand rather -than mocking the entire config subsystem. - -`verify()`: This function validates the internal representation. It must -raise `ConfigError` with a descriptive message if the config is invalid. It -**must not** make any changes to the system. This design enables future features -like commit dry-run ("commit test" as in JunOS) where the system can abort a -commit before making changes. - -`generate()`: This function generates config files for system components. - -`apply()`: This function applies the generated configuration to the live -system. Prefer non-disruptive reload when possible. Disruptive operations like -daemon restarts are acceptable only when: - -- The component does not support non-disruptive reload, or -- The expected service degradation is minimal (for example, auxiliary services - like LLDPd) - -For high-impact services (VPN daemons, routing protocols), make effort to -determine if changes can be applied non-disruptively before resorting to -restarts. - -Never modify active configuration directly unless absolutely necessary. Instead, -generate configuration files and apply them with a single command like service -reload through systemd. For example, save iptables rules to a file and load them -with `iptables-restore` rather than executing iptables commands one by one. - -The `apply()` and `generate()` functions may raise `ConfigError` if the -daemon fails to start with the updated config. However, this is not a substitute -for proper config validation in the `verify()` function. Make reasonable -effort to verify that generated configuration is valid and will be accepted by -the daemon, including cross-checks with other VyOS configuration subtrees when -necessary. - -Exceptions like `VyOSError` (raised by `vyos.config.Config` on improper -operations) should not be silenced or caught.

The signature and first four lines of `get_config(...)` **must** be as - specified above. -2. Each of `get_config`, `verify`, `apply`, and `generate` **must** - appear - with the correct signatures, even if they are a no-op. -3. `Config` objects other than those in `get_config` **must not** appear. -4. The legacy function `my_set` **must not** appear. Modifications to active - config **should not** appear in new code (alternative mechanisms may be used - if absolutely necessary). - -## XML for CLI definitions - -XML interface definitions define the VyOS CLI structure. -Before VyOS `1.2` (crux), these -files were created manually. After a redesign, new-style templates are -automatically generated from XML input files. - -VyOS interface definitions come with a RelaxNG schema located in the -[vyos-1x](https://github.com/vyos/vyos-1x/tree/current/schema) -repository. This schema is a modified version from `VyConf` (VyOS `2.0`). -VyOS `1.2.x` -interface definitions are reusable in future VyOS versions with minimal changes. - -Schemas provide two benefits: - -- Complete grammar verification -- Automatic validation against the schema - -The [build-command-templates](https://github.com/vyos/vyos-1x/blob/current/scripts/build-command-templates) -script converts XML definitions to -old-style templates and verifies them against the schema. A bad definition -causes the package build to fail. While the XML format is verbose, no other -format provides this level of verification. Specialized XML editors can help -manage verbosity. - -Example XML interface definition: - -```xml -<?xml version="1.0"?> -<!-- Cron configuration --> -<interfaceDefinition> - <node name="system"> - <children> - <node name="task-scheduler"> - <properties> - <help>Task scheduler settings</help> - </properties> - <children> - <tagNode name="task" owner="${vyos_conf_scripts_dir}/task_scheduler.py"> - <properties> - <help>Scheduled task</help> - <valueHelp> - <format><string></format> - <description>Task name</description> - </valueHelp> - <priority>999</priority> - </properties> - <children> - <leafNode name="crontab-spec"> - <properties> - <help>UNIX crontab time specification string</help> - </properties> - </leafNode> - <leafNode name="interval"> - <properties> - <help>Execution interval</help> - <valueHelp> - <format><minutes></format> - <description>Execution interval in minutes</description> - </valueHelp> - <valueHelp> - <format><minutes>m</format> - <description>Execution interval in minutes</description> - </valueHelp> - <valueHelp> - <format><hours>h</format> - <description>Execution interval in hours</description> - </valueHelp> - <valueHelp> - <format><days>d</format> - <description>Execution interval in days</description> - </valueHelp> - <constraint> - <regex>[1-9]([0-9]*)([mhd]{0,1})</regex> - </constraint> - </properties> - </leafNode> - <node name="executable"> - <properties> - <help>Executable path and arguments</help> - </properties> - <children> - <leafNode name="path"> - <properties> - <help>Path to executable</help> - </properties> - </leafNode> - <leafNode name="arguments"> - <properties> - <help>Arguments passed to the executable</help> - </properties> - </leafNode> - </children> - </node> - </children> - </tagNode> - </children> - </node> - </children> - </node> -</interfaceDefinition> -``` - -XML definitions are purely declarative and contain no logic. All logic for -generating config files, restarting services, and related tasks is implemented -in configuration scripts. - -### Template Processors - -XML interface definition files use the `.xml.in` file extension (implemented -in {vytask}`T1843`).
