If you only want to build yourself a fresh ISO +you can completely skip this chapter. It may become interesting once you have +a VyOS deep dive. + +vyos-netplug +^^^^^^^^^^^^ + +Due to issues in the upstream version that sometimes set interfaces down, a +modified version is used. + +The source is located at https://github.com/vyos/vyos-netplug + +In the future, we may switch to using systemd infrastructure instead. Building +it doesn't require a special procedure. + +keepalived +^^^^^^^^^^ + +Keepalived normally isn't updated to newer feature releases between Debian +versions, so we are building it from source. + +Debian does keep their package in git, but it's upstream tarball imported into +git without its original commit history. To be able to merge new tags in, we +keep a fork of the upstream repository with packaging files imported from +Debian at https://github.com/vyos/keepalived-upstream + +strongswan +^^^^^^^^^^ + +Our StrongSWAN build differs from the upstream: + +- strongswan-nm package build is disabled since we don't use NetworkManager +- Patches for DMVPN are merged in + +The source is at https://github.com/vyos/vyos-strongswan + +DMVPN patches are added by this commit: +https://github.com/vyos/vyos-strongswan/commit/1cf12b0f2f921bfc51affa3b81226 + +Our op mode scripts use the python-vici module, which is not included in +Debian's build, and isn't quite easy to integrate in that build. For this +reason we debianize that module by hand now, using this procedure: + +0. Install https://pypi.org/project/stdeb/ +1. `cd vyos-strongswan` +2. `./configure --enable-python-eggs` +3. `cd src/libcharon/plugins/vici/python` +4. `make` +5. `python3 setup.py --command-packages=stdeb.command bdist_deb` + +The package ends up in deb_dist dir. + +ppp +^^^ + +Properly renaming PPTP and L2TP interfaces to pptpX and l2tpX from generic and +non-informative pppX requires a patch that is neither in the upstream nor in +Debian. + +We keep a fork of Debian's repo at https://github.com/vyos/ppp-debian + +The patches for pre-up renaming are: + +* https://github.com/vyos/ppp-debian/commit/e728180026a051d2a96396276e7e4ae +* https://github.com/vyos/ppp-debian/commit/f29ba8d9ebb043335a096d70bcd07e9 + +Additionally, there's a patch for reopening the log file to better support +logging to files, even though it's less essential: +https://github.com/vyos/ppp-debian/commit/dd2ebd5cdcddb40230dc4cc43d374055f + +The patches were written by Stephen Hemminger back in the Vyatta times. + +mdns-repeater +^^^^^^^^^^^^^ + +This package doesn't exist in Debian. A debianized fork is kept at +https://github.com/vyos/mdns-repeater + +No special build procedure is required. + +udp-broadcast-relay +^^^^^^^^^^^^^^^^^^^ + +This package doesn't exist in Debian. A debianized fork is kept at +https://github.com/vyos/udp-broadcast-relay + +No special build procedure is required. + +Linux kernel +^^^^^^^^^^^^ + +In the past a fork of the Kernel source code was kept at the well-known +location of https://github.com/vyos/vyos-kernel - where it is kept for history. + +Nowadays the Kernel we use is the upstream source code which is patched +with two additional patches from the good old Vyatta times which never made it +into the mainstream Kernel. The patches can be found here: +https://github.com/vyos/vyos-build-kernel/tree/master/patches/kernel and are +automatically applied to the Kernel by the Jenkins Pipeline which is used to +generate the Kernel binaries. + +The Pipeline script not only builds the Kernel with the configuration named +``x86_64_vyos_defconfig`` which is located in the vyos-build-kernel repository, +too - but in addition also builds some Intel out-of-tree drivers, WireGuard +(as long it is not upstreamed) and Accel-PPP. + +The ``Jenkinsfile`` tries to be as verbose as possible on each individual build +step. + +Linux Firmware +^^^^^^^^^^^^^^ + +More and more hardware cards require an additional firmware which is not open +source. The Kernel community hosts a special linux-firmware Git repository +with all available binary files which can be loaded by the Kernel. + +The ``vyos-build`` repository fetches a specific commit of the linux-firmware +repository and embeds those binaries into the resulting ISO image. This step is +done in the ``data/live-build-config/hooks/live/40-linux-firmware.chroot`` file. + +If the firmware needs to be updated it is sufficient to just exchange the Git +commit id we reference in our build. + +Intel NIC drivers +^^^^^^^^^^^^^^^^^ + +We do not make use of the building Intel NIC drivers except for e1000e. Main +reason is that the out of tree Intel drivers seem be perform a bit better, +e.q. have proper receive-side-scaling and multi-queue support. + +Drivers are build as part of the Kernel Pipeline - read above. + +Accel-PPP +^^^^^^^^^ + +Accel-PPP used to be an upstream fork for quite some time but now has been +converted to make use of the upstream source code and build system. + +It is build as part of the Kernel Pipeline - read above. + +hvinfo +^^^^^^ + +A fork with packaging changes for VyOS is kept at https://github.com/vyos/hvinfo + +The original repo is at https://github.com/dmbaturin/hvinfo + +It's an Ada program and requires GNAT and gprbuild for building, dependencies +are properly specified so just follow debuild's suggestions. diff --git a/docs/index.rst b/docs/index.rst index 8b5c4e5d..f6e09a8b 100644 --- a/docs/index.rst +++ b/docs/index.rst @@ -72,6 +72,7 @@ VyOS User Guide :maxdepth: 2 contributing/build-vyos + contributing/upstream-packages contributing/issues-features contributing/development contributing/documentation |
