% Libreboot build system audit plus next-release plans % Leah Rowe % 13 June 2023

Introduction

Literally about 200+ changes have been made to the Libreboot build system, since the last release of Libreboot. This has been the primary focus, thus far.

In recent weeks, Libreboot's build system has gone through an intense audit and until recent days has undergone extensive testing. There are still a few more things to be done. The purpose of this audit has been to:

  • Look for and fix bugs
  • Improve code quality (nicer coding style)
  • Reduce code repetition

This concerns only lbmk, the automated build system that Libreboot uses. This is what Libreboot uses to build coreboot, payloads, utilities, ROM images and, ultimately, Libreboot releases, so one could argue that lbmk is Libreboot. It automatically downloads, patches, pre-configures and compiles everything from scratch, but in a way that is simplified from the perspective of the end user (almost everything is just a single command, where users are typically not required to edit any files unless they want to).

Brief summary of changes

In short, the following work has been performed:

  • OpenBSD coding style more rigorously adopted, on some C utilities included in lbmk; though this was already the case for some of them.
  • That same BSD coding style has been adapted for use with shell scripts.
  • Vastly improved error handling, on some scripts (in many cases, errors that were previously unhandled are now handled fully).

Example of build system cleanup recently performed: all scripts in the main directory of lbmk are now consolidated into a single shell script. Similar cleanup is underway for other parts of the build system.

Libreboot's build system is already very efficient. It's only a few thousand source lines (about 2200, at the last count). Libreboot's build system provides the minimal glue necessary to download, patch, configure and build ROM images for end users. The mentality behind is is that every codebase on average probably has the same percentage of bugs, so less code means less bugs, so less code is good. Many people ask how but the most important question is usually why (or when). Libreboot's build system tries to avoid bloat and feature creep when possible, intentionally refusing to implement certain features that are considered superfluous.

Example of BSD coding style on shell scripts

One of the most common practises in BSD style in top-down logic, which makes programs much easier to read (in my opinion). Here is an example of the BSD coding style in use within lbmk. Here is the old coreboot download script in lbmk:

https://browse.libreboot.org/lbmk.git/plain/resources/scripts/download/coreboot?id=7f5dfebf7d37c56d9c7993aaa17c59070cb5aec9

And here is that same script, after auditing and cleanup with the BSD style adapted:

https://browse.libreboot.org/lbmk.git/plain/resources/scripts/download/coreboot?id=52d87f5f086041c94340d460d74d77a2253e9d7f

The trick is to have a main() at top, and add this line at the bottom of the script:

main $@

This will pass all arguments on the shell, to the main() function. Where possible, only global variables are written outside functions, with no other logic written (all logic is to be written inside functions).

Where feasible, and desirable, this style will now be used for all new scripts in the Libreboot build system, with existing scripts modified accordingly. This and other work is ongoing.

Auditing of utilities

This process has also been applied to some of the utilities (written in C) that Libreboot includes as part of lbmk. The following utilities have been audited:

  • spkmodem-recv (more on this in a moment)
  • e6400-flash-unlock (minor cleanup, basically removing one unused function)
  • nvmutil (massive code size reduction, minor fixes here and there)

Pledge

The nvmutil program was already pledged, when compiled on OpenBSD, but it was not handled well. It is now handled correctly (correct ifdef rule), and it has been hardened greatly.

The code has also been unveiled. See manpages:

https://man.openbsd.org/pledge.2

https://man.openbsd.org/unveil.2

spkmodem-recv

This utility was added after the last release. It was imported from coreboot, which in turn previously forked it from GNU GRUB. It is a receiving client for spkmodem, to provide a serial console via pulses on the standard PC speaker.

Libreboot's version is heavily re-factored, doing away with the GNU coding style and replacing it with a BSD coding style (the licensing is unchanged).

For reference, here is the original version from GRUB:

https://git.savannah.gnu.org/cgit/grub.git/plain/util/spkmodem-recv.c?id=822b726b33b8dc07dd01b257a2dfcc7b07d12e2f

And here is the version coreboot had, which Libreboot forked:

https://raw.githubusercontent.com/coreboot/coreboot/8febc91b3041a1d027bf0d36d30ccb119496524f/util/spkmodem_recv/spkmodem-recv.c

And here is the Libreboot version, as of today, 13 June 2023:

https://browse.libreboot.org/lbmk.git/plain/util/spkmodem_recv/spkmodem-recv.c?id=5be3d67ced51236cb4e370d8ea755d905a905e1d

In addition to code style changes, certain variables are renamed for clarity, and certain redundant variables removed. Logic split into functions, and the code is conditionally pledged if you compile it on OpenBSD (for OpenBSD), see: https://man.openbsd.org/pledge.2

Other plans for next release

I have a bunch of Dell/HP boards that I plan to add, which I would have added already but I've focused on the audit (which is more or less complete, now).

Besides this, I also wish to:

  • Re-add Tianocore UEFI payload, on boards where this is feasible, providing it as an option alongside existing GRUB/SeaBIOS payloads
  • Provide a Linux kexec payload, based on the Linux payload provided by Heads. I was initially working on a port of the OpenBSD userland to Linux and musl first, because I want to replace busybox, but this is taking too long so I've shelved it and will release that at a later date. The Heads build system is already excellent for this purpose (though they use busybox, in their linux distro), and I intend to adapt (directly adapt) their build system to be used in lbmk (re-implement the same logic, but in shell scripts, where Heads currently uses a lot of Makefiles that I find messy in comparison to lbmk's way of doing things - though their way also has its benefits)
  • If time, test more ChromeOS boards (gru-* but also the nyan, peach and veyron boards, most of which are untested. Only the gru platforms are known to work with Libreboots u-boot payload, at present).
