2024-06-09lib.sh: fix regressionLeah Rowe
i was being a bit too clever about some optimisations revert this change. otherwise, nothing will download or build Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-09git.sh: download xtree *before*, not afterLeah Rowe
downloading it after means that if an error occurs when downloading the xtree project, the main project will still be there and nothing will mandate the downloading of the xtree project. whereas, if we grab the xtree project first, then the main project won't get saved to src/ this makes the build system a bit more resilient under fault conditions, but otherwise doesn't change behaviour.

2024-06-09lib.sh: less confusing error in download()Leah Rowe
don't say "file missing", because it may be present! instead, say that the download failed. this covers both contexts: internet failed and thus no file present, or the file is present but checksum verification failed. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-09lib.sh: hide stderr on download()Leah Rowe
on the initial check, the output is confusing because it will say "checksum verification failed" if the file doesn't already exist, but then goes to download. only say checksum failed if a download occured, and the check failed, otherwise report nothing except that the file already exists. this will not reduce the ability to debug issues later on, and it will reduce the amount of confusion for users.

2024-06-08git.sh: support downloading *files* as submodulesLeah Rowe
when we download coreboot, we currently don't have a way to download crossgcc tarballs, so we rely on coreboot to do it, which means running the coreboot build system to do it; which means we don't get them in release archives, unless we add very hacky logic (which did exist and was removed). the problem with coreboot's build system is that it does not define backup links for each given tarball, instead relying on gnu.org exclusively, which seems OK at first because the gnu.org links actually return an HTTP 302 response leading to a random mirror, HOWEVER: the gnu.org 302 redirect often fails, and the download fails, causing an error. a mitigation for this has been to patch the coreboot build system to download directly from a single mirror that is reliable (in our case mirrorservice.org). while this mitigation mostly works, it's not redundant; the kent mirror is occasionally down too, and again we still have the problem of not being able to cleanly provide crossgcc tarballs inside release archives. do it in config/submodules, like so: module.list shall say the relative path of a given file, once downloaded, relative to the given source tree. module.cfg shall be re-used, in the same way as for git submodules, but: subfile="url" subfile_bkup="backup url" do this, instead of: subrepo="url" subrepo_bkup="backup url" example entries in module.list: util/crossgcc/tarballs/binutils-2.41.tar.xz util/crossgcc/tarballs/gcc-13.2.0.tar.xz util/crossgcc/tarballs/gmp-6.3.0.tar.xz util/crossgcc/tarballs/mpc-1.3.1.tar.gz util/crossgcc/tarballs/mpfr-4.2.1.tar.xz util/crossgcc/tarballs/nasm-2.16.01.tar.bz2 util/crossgcc/tarballs/R06_28_23.tar.gz the "subrev" variable (in module.cfg) has been renamed to "subhash", so that this makes sense, and that name is common to both subfile/subrepo. the download logic from the vendor scripts has been re-used for this purpose, and it verifies files using sha512sum. therefore: when specifying subrepo(git submodule), subhash will still be a sha1 checksum, but: when specifying subfile(file, e.g. tarball), subhash will be a sha512 checksum the logic for both (subrepo and subfile) is unified, and has this rule: subrepo* and subfile* must never *both* be declared. the actual configuration of coreboot crossgcc tarballs will be done in a follow-up commit. this commit simply modifies the code to accomodate this. over time, this feature could be used for many other files within source trees, and could perhaps be expanded to allow extracting source tarballs in leiu of git repositories, but the latter is not yet required and thus not implemented.

2024-06-07git.sh: simplify prep_submodules()Leah Rowe
copying the module list into tmpdir/ no longer makes sense, because it was only done before when we supported either running the list from "git submodule update", or module.list. since we only support handling of module.list, we can greatly simplify this function.

2024-06-07git.sh: provide feedback for repository downloadsLeah Rowe
otherwise, it's not clear to the operator what's happening i'm normally against such verbose feedback, because it's bloat, but this minimal amount of feedback will make the build system more pleasant to use, especially during testing. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-07git.sh: download "depend" projects *before*Leah Rowe
don't do it after, because that means the main project is saved under src/ before we know whether the subrepo was downloaded. the "depend" variable (in config/git/) is no longer used for projects that go in subdirectories of a parent; now, we use config/submodules/ for this type of dependency. download the "depend" projects (as per config/git/) first. this way, if they fail, the main one will fail, but if they succeed and main fails, you can just run the main download again and it won't fail. this fixes a bug where, depending on how you download a set of projects and depending on the order which you do so, a given project can become un-downloadable on current design, because git will complain that a directory already exists. this fix is done not only in code (by this commit), but by prior configuration changes.

2024-06-07git.sh: *never* run git submodule updateLeah Rowe
only use config/submodules/ which the build system then uses to run git clones manually, replicating the submodules feature. we must never use a project's own gitmodules feature, because we can't easily control it. better to let it break first, and then figure out what modules to add manually, so that we have only what we need for each project. it's done this way, because git's own submodules feature doesn't have very good error checking in general, nor does it have good redundancy. with the current design, we can declare backup repositories for each submodule. we replicate it precisely. for example: 3rdparty/vboot this is a coreboot submodule, and we handle that in the coreboot trees. however, our current design also allows you to do this even if the upstream repository does not contain a .gitmodules file Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-06-06git.sh: use singletree() to decide submodulesLeah Rowe
now it no longer hardcodes a check for whether the project name is coreboot. this maintains the same behaviour but will now work for other multi-tree projects; in practise, the other multi-tree projects did not use .gitmodules files anyway, but some of them used config/submodules/ in our build system.

2024-06-06handle build.list from config/data/, not config/Leah Rowe
certain code checks for build.list, to skip it, for example in items() we already use config/data/grub to store grub config data that applied to all trees create these directories too: config/data/coreboot config/data/u-boot config/data/seabios move the respective build.list files in here, and also to config/data/grub now multi-tree projects contain, per directory, just the target.cfg file and the patches directory. this is much cleaner, because some of the logic can be simplified more Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-06-06don't use build.list to detect multi-tree projectsLeah Rowe
instead, check for the presence of target.cfg files not in config/project/ but config/project/tree/ the way this check is done, it merely returns 1 if config/project/*/target.cfg is detected, and returns 0 in all other cases, even if config/project/target.cfg exists that way, if the maintainer accidentally adds a target.cfg in the main directory, the given multi-tree project will not break Signed-off-by: Leah Rowe <leah@libreboot.org>

2024-06-05move root check to lib.sh (bugfix)Leah Rowe
this avoids writing the version/versiondate files as root. this complements the previous fix, that avoided writing those same files when running the dependencies command. initial setup of the build system requires root, to run the dependencies script, but otherwise the build system prevents running as root for everything else, so we must avoid writing the version/versiondate files as root. that same avoidance is necessary when checking whether running other commands as root; ironically, this check then prevented running the build system at all! the bug should be fully fixed now. i found this quite by accident the other day, when testing something else. good thing this got fixed because the release!

2024-06-05bugfix: move dependencies handling to lib.shLeah Rowe
do it strategically, in just the right place so that the version and versiondate files aren't written. otherwise, version/versiondate are written as root and the build system becomes unusable after that, unless you reset the file ownerships from root. hardly user-friendly. mitigate this bug.

2024-06-03lib.sh: more friendly output from e()Leah Rowe
already of saying "found", say "already exists" this means the output of these commands more user friendly and intuitive: ./update trees -b grub default ./update trees -b coreboot i945 this is just an example. when an ELF file already exists, the build is skipped even if src isn't downloaded. this design is intentional, because it means that you can use previous builds if you want to save time on another.

2024-06-02make GRUB multi-tree and re-add xhci patchesLeah Rowe
Re-add xHCI only on haswell and broadwell machines, where they are needed. Otherwise, keep the same GRUB code. The xHCI patches were removed because they caused issues on Sandybridge-based Dell Latitude laptops. See: https://codeberg.org/libreboot/lbmk/issues/216 The issue was not reported elsewhere, including on the Haswell/Broadwell hardware where they are needed, but the build system could only build one version of GRUB. The older machines do not need xHCI patches, because they either do not have xHCI patches, or work (in GRUB) because they're in EHCI mode when running the payload. So, the problem is that we need the xHCI patches for GRUB on Haswell/Broadwell hardware, but the patches break Sandybridge hardware, and we only had the one build of GRUB. To mitigate this problem, the build system now supports building multiple revisions of GRUB, with different patches, and each given coreboot target can say which GRUB tree to use by setting this in target.cfg: grubtree="xhci" In the above example, the "xhci" tree would be used. Some generic GRUB config has been moved to config/data/grub/ and config/grub/ now looks like config/coreboot/ - also, the grub.cfg file (named "payload" in each tree) is copied to the GRUB source tree as ".config", then added to GRUB's memdisk in the same way, as grub.cfg. Several other design changes had to be made because of this: * grub.cfg in memdisk no longer automatically jumps to one in CBFS, but now shows a menuentry for it if available * Certain commands in script/trees are disabled for GRUB, such as *config make commands. * gnulib is now defined in config/submodule/grub/, instead of config/git/grub - and this mitigates an existing bug where downloading gnulib first would make grub no longer possible to download in lbmk. The coreboot option CONFIG_FINALIZE_USB_ROUTE_XHCI has been re-enabled on: Dell OptiPlex 9020 MT, Dell OptiPlex 9020 SFF, Lenovo ThinkPad T440p and Lenovo ThinkPad W541 - now USB should work again in GRUB. The GRUB payload has been re-enabled on HP EliteBook 820 G2. This change will enable per-board GRUB optimisation in the future. For example, we hardcode what partitions and LVMs GRUB scans because * is slow on ICH7-based machines, due to GRUB's design. On other machines, * is reasonably fast, for automatically enumerating the list of devices for boot. Use of * (and other wildcards) could enable our GRUB payload to automatically boot more distros, with minimal fuss. This can be done at a later date, in subsequent revisions.

2024-05-30git.sh: do not remove .submodulesLeah Rowe
the reason for it is because sometimes the coreboot build system auto-downloads submodules which we don't want. however, we now pass UPDATED_SUBMODULES=1 in make, which disables this behaviour in coreboot's build system. therefore, remove this unnecessary logic.

2024-05-30import nuke() from cbmk cdce8ba70bLeah Rowe
cbmk revision: cdce8ba70b863ea3fe0ad7a4d7b27d0c5ca30421 as of date 30 May 2024 Canoeboot provides deblobbing, fully, on all sources, so as to provide a GNU FSDG compliant coreboot distro. Libreboot used to do this but now uses a more pragmatic Binary Blob Reduction Policy, allowing better hardware support in general. See: https://libreboot.org/news/policy.html Well! We sometimes still need to delete files in Libreboot, but for other reasons. For example, the poorly licensed strlcat.c file that we delete from U-Boot, in both projects. I currently hardcode such deletions in lbmk. After this revision, I will start using "nuke.list" files as in cbmk. Simply patching the sources to exclude such files, in this context, is not OK because then we are still including them but as diffs. This is why the nuke() function exists. Import Canoeboot's nuke technology. Signed-off-by: Leah Rowe <leah@libreboot.org>
2024-05-29./vendor download: skip if blob path is /dev/nullLeah Rowe
We use a path of /dev/null pointing to a ROM for Fam15h AMD boards, to add fake PIKE2008 images. This is to mitigate a hang in SeaBIOS, but now with recent changes, this causes the command below to download coreboot, when it should just exit saying no vendor files needed. Prevent accidentally wasted bandwidth. The command was: ./vendor download kcma_d8_rdimm_16mb This now correctly does the following: $ ./vendor download kcma_d8_rdimm_16mb Vendor files not needed for: kcma_d8_rdimm_16mb The joys of programming a build system in sh!

2024-05-29./vendor download: more fine-tuned error controlLeah Rowe
By default, the build system does set -u -e Some errors are unavoidable and have to be handled, so we have to set +u +e (turn off error handling in sh), when downloading vendor files, but only certain parts of vendor.sh trigger errors (which cause an exit). Replace the current bazooka approach with a more fine grained approach, turning error handling back on again when it is safe to do so. In the parts of the code where it is disabled, the code is written very, very carefully, with errors still handled manually, but more careful auditing is required. This change has been tested and makes the command much safer to run. In security (or any bug auditing), it is the principle of least privilege that holds true.
