% Libreboot Build System Audit 4
% Leah Rowe
% 31 December 2023
Introduction
============
This article pertains to the current Libreboot (lbmk) revision at this time
of writing, which is `f3098f566ca89f6d7ebc8e91e2a78e751a7ef924` from 31
December 2023. A *release* is also being considered for some time in January
of 2024, based on this audit and new features that are planned, plus new
boards. To compliment this audit, the [TODO page](../tasks/), which now lists
what tasks the project is interested in or working on at any given time.
A lot of work has gone into Libreboot since [Libreboot Build System
Audit 3](audit3.md), which coincided with
the [Libreboot 20231021](libreboot20231021.md) release, right up
to [Libreboot 20231106](libreboot20231106).
Modest code size reduction
--------------------------
The main purpose of audit 4 has been to *finish* audit 3. More logic has been
generalised, and *another* sloccount reduction has been observed: 1618 SLOC in
the shell scripts, versus 1744 as of audit 3, with *increased* (not decreased)
functionality. This accounts for a *7.22%* decrease in the complexity of
[lbmk](../docs/maintain/), which is the Libreboot build system.
Summarised changes since 20231106
-------------------------------
These and subsequent changes will be present in the *next Libreboot release*,
after Libreboot 20231106, but they can already be obtained now, if you compile
Libreboot [from source via lbmk.git](../docs/build/).
Although audit 3 was the previous audit, several changes were made after
that, up to the Libreboot 20231106 release. Therefore, this audit changelog is
relative to Libreboot 20231106, *not* audit 3. Most of this is minor code
cleanup patches that, together, account for the moderate code size reduction,
but there are some new features and bug fixes too.
Not all of these are actually audit-related, but are still nice changes, and
will be included in the release changelog, for the next release
after Libreboot 20231106. The changes are, from newest to oldest:
In addition to specific changes listed below, there are several commits part of
the audit titled "general code cleanup", which go through the entire build system,
sweeping it for bad or unclean code, cleaning up the coding style, removing
obsolete code or generally improving the coding style/quality, to make the
code more readable. Such has been the main focus of this audit.
And now, specific changes:
* `target.cfg` files are now possible for single-tree projects, not just
multi-tree projects. For single-tree projects, it goes
at `config/projectname/target.cfg`, and it goes on the
existing `config/projectname/tree/target.cfg` location for multi-tree projects.
* `script/update/trees`: Support adding custom arguments to the make command,
when running a makefile within a project. This is defined by `makeargs` in
the `target.cfg` file for a given project.
* Generic cmake handling now supported, in `script/update/trees` - it is no
longer hardcoded, for the `uefitool` package (from which we
run `uefiextract`). Simply: define `cmakedir` in a project `target.cfg` file.
It could even be `cmakedir="."` if you wish, so that all of it is built,
though we specify `cmakedir="UEFIExtract"` for uefitool.
* Unify `script/update/trees` and `script/build/grub` - now, generic autoconf
handling is present in `script/update/trees`, so it can be used for any
project, including GRUB, and arguments for configure/autogen/bootstrap scripts
are configurable in project `target.cfg` files. The actual running
of `grub-mkstandalone` is now handled from `script/build/roms`. This reduces
the number of shell scripts from 12 to 11, in lbmk.
* disable u-boot on x86 qemu for now (prevents a build error in lbmk)
* `script/build/serprog`: Return error status (exit) if basename fails, when
processing various board targets available on stm32/rp2040 projects. Patch
courtesy of Leah Rowe.
* **NEW BOARD:** HP 8300 CMT mainboard, added by Riku Viitanen.
* Fixed implicit typecasting bug on flashrom 1.2 source code, thus preventing
a build issue (tested on Debian 12.2). Patch courtesy of Leah Rowe.
* `script/build/roms`: Rename `check_target` to `configure_target`
and `prepare_target` to `configure_dependencies`, for increased code clarity.
* `git/pico-serprog`: Use Riku's newer revision, which sets the drive level
to 12mA by default, up to the previous default of 4mA. The new level is
within safety specifications on all flash ICs, but will result in greater
reliability, especially on ISP-based flashing setups. Also merged a fix by
Riku Viitanen, fixing a build error on boards where `PICO_DEFAULT_LED_PIN` is
not defined by the pico sdk; in these cases, the status LED is simply unused.
* `script/build/roms`: Improved error handling for ROM image build functions,
which run inside subshells. They now more reliably cause an exit from lbmk,
under error conditions, and those exits are guaranteed now to be non-zero.
Patch courtesy of Leah Rowe.
* `script/build/roms`: Remove redundant check on cros roms, where it
checked whether initmode was normal; on these setups, it's always libgfxinit.
* **BOARD:** the `e6400_4mb` target is unaltered, but now a
new `e6400nivida_4mb` target is defined. This target disabled libgfxinit,
and only executes the nvidia VGA ROM, so it's only applicable to the nvidia
variant of Dell Latitude E6400. The `e6400_4mb` variant enables both, but
causes some issues on nvidia models when `nomodeset` is used - only KMS works,
but nouveau is unstable in certain conditions and on some linux/mesa versions,
with this board when Libreboot is used. So it's recommended on nvidia variants
to use the `e6400nvidia_4mb` option, and use `e6400_4mb` only on intel variants.
Patch courtesy Leah Rowe, responding to a bug report on the IRC channel.
* set projectname/version strings properly, in scripts that call it. It was
previously done unconditionally in err.sh, without being called, but this
was later changed, and scripts that use it weren't adapted, so it turned
out that the strings were empty when used. Now the strings are properly set,
in all scripts that need them. These strings are provided by the build system,
which checks itself at startup. Patch courtesy of Leah Rowe.
* `script/update/trees`: Fix infinite loop caused in some conditions, when
vendor files are being used. The trees script calls the vendor download
script, which in turn calls the trees script; an additional check has been
introduced, to prevent a runaway condition where the two scripts endlessly
call each other, thus preventing an infinite loop. Patch courtesy Leah Rowe.
* `script/vendor/download`: check whether a config file exists, before trying
to read it. This reduces the chance of crashing the build system, when running
the script on certain targets. Patch courtesy of Leah Rowe.
* `script/vendor/inject`: Fixed a bad error check, when running `cd` to switch
to the ROM images directory, when creating archives. Patch courtesy Leah Rowe.
* Don't delete microcode updates on GM45 ROMs in releases. Microcode updates
are always included in builds, but the release build scripts were copying
certain ROM images to cerate versions (alongside the default ones) with
microcode disabled. This is no longer required, due to the existence of
the [Canoeboot project](https://canoeboot.org/). You can also still delete them
very easily, using cbfstool, if they are included in a given set of images,
so this change reduces the uncompressed size of the ROM images in releases.
This also means that the file names of all ROM images now match the file names
in canoeboot images, when dealing with a mainboard supported by both projects.
Patch courtesy of Leah Rowe.
* `script/update/release`: Don't test `script/vendor/inject` at the end. This
is regularly tested anyway, during development, so it's a waste of time to
have it done by the release build script. This reduces the amount of time
taken to build a release archive. Patch courtesy of Leah Rowe.
* `script/update/release`: Don't insert crossgcc tarballs into release
archives. These are re-inserted needlessly, when they are already hosted by
the GNU project and have decent mirrors in general. I always keep backups of
these anyway, and do several mirrors, and not including them reduces the
size of the Libreboot release archives. This means that the release archives
now require an internet connection to use, because crossgcc tarballs will be
downloaded at build time, but they are the same tarballs that you would
download as part of a release anyway, but now if you're only building for
one coreboot tree within lbmk, you only need to download one set of archives
instead of getting them all. Patch courtesy of Leah Rowe.
* `script/build/serprog`: general code cleanup, generalising a lot more code,
especially the if/else chains for checking what type of firmware is build.
Patch courtesy of Leah Rowe.
* main build script: simplified TMPDIR handling. There were cases where the
TMPDIR variable was already set, and being re-set needlessly. The new code
is simpler, and less error-prone. Patch courtesy of Leah Rowe.
* `include/mrc.sh`: general code cleanup, removing dead code and optimising the
general style of it, to reduce sloccount. Patch courtesy of Leah Rowe.
* Corresponding to the change below by Riku, the vendor filenames were also
changed to match the 68\* naming scheme.
* `config/vendor/sources`: document HP laptop ROM families, for certain models,
according to name scheme 68SFC, 68SCE, 68ICE and 68ICF. Some of these boards
iare part of the same families, and use the same blobs. Patch courtesy of
Riku Viitanen.
* `script/build/roms`: remove the `modify_coreboot_rom` function. Fake PIKE2008
ROMs are now inserted by defining option roms in the coreboot config, where
the given path is `/dev/null`. The *top swap* setting on i945 is now enabled
via `CONFIG_INTEL_ADD_TOP_SWAP_BOOTBLOCK` in the coreboot build system -
basically, what this does is cat two identical copies of the bootblock together
and insert the larger bootblock file (twice the size) at the end of the flash,
whereas previously we did this in lbmk using dd. The benefit of the new setup
is that it results in higher build speeds, and now the duplicated bootblock
now appears in CBFS, so cbfstool will prevent overwriting it.
* `include/mrc.sh`: Also don't use the dedicated unzip logic in the script.
Re-use the generic logic provided by `include/git.sh` instead. Patch courtesy
of Leah Rowe.
* `include/mrc.sh`: Don't run the shellball provided by Google. Just directly
run `unzip` instead. The shellball is just a zip file attached to some shell
logic, that self-decompresses itself. Running unzip directly, gets you the
same hash, and it's much simpler in lbmk. Patch courtesy of Leah Rowe, after
the shellball's behaviour was pointed out by Nicholas Chin.
* `script/update/trees`: Greatly simplified crossgcc handling. Now the list of
crossgcc targets are directly defined in `target.cfg` files, and the for loop
in update/trees just goes through it, checking the relevant toolchain. Patch
courtesy of Leah Rowe.
* `config/ifd/xx30`: Fixed bad component density count for 16MB setups, and
reduced chip count from 2 to 1. This should make internal flashing work, on
X230 setups where the user replaced the two flashes with a single 16MB flash.
Patch courtesy of Nicholas Chin.
* **NEW BOARD:** HP EliteBook 8460p support added. Patch courtesy of Riku
Viitanen, who worked on it with a tester in the IRC channel.
* `include/git.sh`: Simplified submodule handling by not using subshells for
running `cd` to a git repository. Instead, the `-C` option is used in Git.
* main build script, in the `initialise_command` (now `initcmd`) function:
simplify handling of arguments, when determining what command was passed,
and how to run it. Patch courtesy Leah Rowe.
* `script/update/release`: remove unnecessary "continue" command at the end of
a for loop.
* `include/option.sh`: general code cleanup in the `scan_config()` function,
on the if/else block assigning variables after scanning configs.
* `include/option.sh`: print errors to stdout instead, on the `item()` function
* `include/git.sh`: reduced code indentation, on the part that applies patches
in a git repository.
* `include/git.sh`: simplify tree name check, by breaking earlier when the
correct tree name is found on a multi-tree project. Patch courtesy of
Leah Rowe.
* `grub.cfg`: Support scanning for *extlinux* configs, which are essentially the
same as syslinux ones. If found, they are passed through GRUB's syslinux
parser, which then presents a menu as if it were a GRUB configuration. This
should increase compatibility with distros that use extlinux, such as
the Alpine Linux distribution.
* `grub.cfg`: Handle GRUB *and* syslinux/extlinux configs, on the USB boot menu
option. Now it scans for both, thus increasing compatibility with many modern
Linux distro installers. Before this change, Libreboot's design was made with
BIOS systems in mind, because we historically only supported systems that were
BIOS-based, whereas GRUB is more common as a bootloader on UEFI-based install
media, but in the past we mostly assumed isolinux/syslinux for that.
* `grub.cfg`: support ESP and extlinux setups. The so-called EFI System Partition
is basically a FAT32 partition that can contain bootloaders and configurations,
and it is commonly used on some machines that Libreboot supports, prior to
Libreboot installation. GRUB also supports parsing syslinux configs, and extlinux
configs are essentially the same. So now Libreboot GRUB automatically scans
for GRUB *and* syslinux/extlinux configs by default, including on the ESP.
This will increase compatibility with a wide variety of distros, *without*
introducing UEFI support yet on x86, because those same Linux kernels can
also run on bare metal (and this is exactly how it works, when you use GRUB
as a payload).
* `grub.cfg`: Don't boot linux unless there is a grub.cfg file provided on
the HDD/SSD. Previously, a fallback entry existed as a last resort, if all
else failed, but it made several assumptions that are mostly no longer valid
in 2023. Patch courtesy of Leah Rowe.
* `grub.cfg`: scan LVMs first. This makes it more likely that an encrypted
system (encrypted `/boot`) will boot first, once found and unlocked. Patch
courtesy of Leah Rowe.
* `dell-flash-unlock`: in the README, link to several useful guides including
Open Security Training section about BIOS and SMM internals on x86. Patch
courtesy of Nicholas Chin. In general, update the README to include instructions
related to disabling /dev/mem protection, and info about the newer boards
now added to lbmk, that the utility can be used on.
* `grub.cfg`: Added BTRFS subvolume support, by default. Patch courtesy of
the contributor, alias `semigel`.
* **NEW BOARD:** EDP variant of the ThinkPad X220, for use with eDP mod kits.
These kits enable use of much nicer, higher resolution screens. We already
provided a variant of the X230 for this, in lbmk. Patch courtesy of the
contributor, alias `risapav` (real name not given).
* lbmk: remove support for the DEBUG environmental variable. It was never very
useful anyway, and introduced about 10 years ago when the Libreboot build
system was much less advanced than it is now. We already have much better
debugging these days, when dealing with build system issues. Patch courtesy
of Leah Rowe.
* lbmk scripts: Did a general sweep with shellcheck, fixing errors that it
flagged, such as lack of double quotes in some places, and non-standard
behaviour being used. The actual [patch](https://browse.libreboot.org/lbmk.git/commit/?id=1eb4df6748f94a08d44c623a56417199b99b371d)
shows what is meant by this. Patch courtesy of Leah Rowe.
* lbmk scripts: Handle exit status correctly, when dealing with subshells. This
continues on from the other fix below, after doing a sweep of the entire
build system. Patch courtesy of Leah Rowe.
* `script/update/trees`: Correctly return error status when `git am` fails,
while applying patches. Although it was printing an error message, the
script was making improper use of subshells, leading to a zero exit, when
it should have exited with non-zero status in such situations. Patch/fix
courtesy of Leah Rowe.
* Bumped flashrom revision back to version 1.2, because the 1.4 RC we were
importing has issues (also, Nico Huber's flashprog will probably be used
in future releases of Libreboot). Patch courtesy of Leah Rowe.
* Debian dependencies config: Fixed the freetype dependency, as tested on
modern Debian Sid
* GRUB modules: re-added fat/ntfs file system support. Some users on EFI-based
setups transferring to Libreboot couldn't boot their linux systems, which had
files installed onto EFI System Partitions. The next release after
Libreboot 20231106 will once again work correctly on such setups. Patch
courtesy of Leah Rowe.
* **GRUB revision:** bumped it to November 2023 revision, which contains
several important fixes. Look at the [patch](https://browse.libreboot.org/lbmk.git/commit/?id=47ef411efb6b669b7befd2a1cf22f999d4521999)
for actual fixes, listed in the code import. It's a lot.
* main build script: set `--author` in Git, when re-initialising the Git
history on release archives. Patch courtesy of Leah Rowe.
* lbmk return status: don't rely on return status for unconditional returns.
There were some parts of lbmk that, in practise, would always exit, but could
theoretically not, even when they are supposed to, regardless of exit status.
Patch courtesy of Leah Rowe.
* lbmk help text: support showing the Libreboot version, project name and
the version date, based on git metadata. Patch courtesy of Leah Rowe.
* Re-added GRUB modules: f2fs, json, read, scsi, sleep, diskfilter, hashsum,
loadenv, setjump - needed on some setups. Patch courtesy of Leah Rowe.
* `util/nvmutil`: Added useful help dialog, showing usage instructions when
no/invalid arguments are given. Patch courtesy of Riku Viitanen.
* Fixed the `util/nvmutil` Makefile, courtesy of Riku Viitanen. It was not
properly formatted to include `nvmutil.c`, when running make-all.
* Dell Latitude E6430: Added VBT to CBFS, which was missing in the
Libreboot 20231106 release. Also enable DRAM clear on boot. Patch courtesy
of Nicholas Chin.
* **BOARD ADDED:** Dell Latitude E6530. Courtesy of Nicholas Chin.
* `config/ifd`: Renamed `e6430` to `dell_ivybridge`, because the files can be
re-used by other planned ports for Dell latitudes in lbmk. Patch courtesy of
Nicholas Chin.
