* bootimg_pcbios: include grub as an optional bootloaderVincent Davis Jr9 days1-6/+36
| | | | | | | | | | | | | | | | | | | | | | Commit adds in support for installation of both grub and syslinux using newly added grub functions. Due to the bootimg_biosplusefi source_params['loader'] had to be named source_params['loader-bios'] so not to create conflict in the wics plugin. Commits also adds ability to set and or not set source_params. If source_params set check for both * syslinux * grub if not set default to using syslinux as bootloader.

* bootimg_pcbios: add funcs to configure booting with grubVincent Davis Jr9 days1-0/+167
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Functions added, but not executed during wic image creation include: _get_staging_libdir * Finds target lib directory if for some reason STAGING_LIBDIR isn't set. _do_configure_grub * Will search for a grub configuration passed via bootloader --configfile. If not found build a default one which searches for partition that contains the given the kernel name via grub search module. _do_prepare_grub 1. Sets default values for GRUB_MKIMAGE_FORMAT_PC and GRUB_PREFIX_PATH if none specified. Both variables are required by grub-mkimage. * GRUB_MKIMAGE_FORMAT_PC is used to define target platform. * GRUB_PREFIX_PATH is used to define which directory grub config and modules are going to reside in. 2. Generates grub config to embed into core.img. This config is used to search for partition containing grub config. 3. Creates a custom core.img or grub stage 1.5 with an embedded grub config. 4. Copies all the target built grub modules into GRUB_PREFIX_PATH directory. 5. Creates boot partition _do_install_grub 1. dd target platform specific boot.img to the first 0-440 bytes of the resulting wic image. dd grub stage 1 to wic image. If this wics plugin is used with GPT as partition table format and grub selected as bootloader it's more than likely for grub hybrid booting because bootimg_efi plugin should and more than likely will be used in that case. So, boot.img may be dd regardless if partition table format is GPT or MBR. 2. dd custom core.img (grub stage 1.5) with embedded configuration to the resulting wic image starting at byte 512 up to sizeof(core.img). 3. Both boot.img and core.img are required for legacy bios boot. See grub Wiki for more details on boot.img and core.img. https://en.wikipedia.org/wiki/GNU_GRUB Commit also imports python modules required by the above implemented functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit: 1. Removes all unrequired function parameters. The part parameter was kept due to it's potential future usage in _do_configure_syslinux function. part.fstype specifically may be used with the rootfstype kernel paramater. 2. Sets a default timeout to 500 if bootloader --timeout not specified. To avoid 'None' being placed as the value in resulting configuartion file. 3. Sets a default kernel parameter string if bootloader --append not specified. This also helps avoid 'None' being places as the value in resulting configuration file. 4. Replace all instances of cr_workdir, "/hdd/boot" with variable hdddir as it's set at the top of the function. No, need to re-implement what the variable is already defined to store.

* bootimg_pcbios: seperate bootloader config creationVincent Davis Jr9 days1-13/+18
| | | | | | | | | | | | | | | | | | | Most bootloaders that will be included in this wics plugin will require a configuration file to define kernel params, execute custom modules, or enable the ability to select one of multiple boot entries. Create a seperate generic function to facilitate finding if a bootloader config file passed through bootloader --configfile flag. So, that other functions that are used to create/install a bootloader boot configuration file can leverage the function.

| | | | | | | | | | | | | | | | | | | | | | | | Allow the '+' symbol as a valid character in filenames listed in the IMAGE_EFI_BOOT_FILES variable. The '+' symbol might be used to support boot counting for boot entries, as described in the UAPI Boot Loader Specification [1]: The boot counting data is stored in the name of the boot loader entry. A boot loader entry file name may contain a plus (+) followed by a number. This may optionally be followed by a minus (-) followed by a second number. The dot (.) and file name suffix (conf or efi) must immediately follow. Boot counting is enabled for entries which match this pattern. Example: IMAGE_EFI_BOOT_FILES:append = " entry.conf;loader/entries/entry+3.conf" [1] https://uapi-group.org/specifications/specs/boot_loader_specification/#boot-counting (From OE-Core rev: 3f25822281eb9423ff86105eaebb0bed48663648) Signed-off-by: Igor Opaniuk <igor.opaniuk@foundries.io> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

If UKI is used, then only generate a minimal loader config for systemd-boot which basically just sets a timeout. Also set 5 second timeout by default instead of failing if wic bootloader config is missing. Boot menu is generated at runtime based on UKI binaries found from ESP partition.

* wic: bootimg-efi: Make kernel image installation configurableKareem Zarka2023-12-041-3/+4
| | | | | | | | | | | | | | | | | | | | | The issue with installing the kernel image to both rootfs and boot partition is that some systems rely on the kernel image in rootfs and not in the boot partition. This leads to duplication of the kernel image, which can cause unnecessary storage usage. This patch provides a solution to the problem by adding a new parameter "install-kernel-into-boot-dir" to the wic kickstart file. If this parameter is set to 'true', the plugin will install the kernel image to the boot partition. If the parameter is set to 'false', the plugin will skip installing the kernel image, avoiding duplication.

[...] Images of this type have the advantage that all metadata and payload that makes up the boot entry is monopolized in a single PE file that can be signed cryptographically as one for the purpose of EFI SecureBoot."[1] This commit adds a create-unified-kernel-image=true option to the bootimg-efi plugin for creating a Unified Kernel Image[1] and installing it into $BOOT/EFI/Linux/ with a .efi extension per the the Boot Loader Specification[1][2]. This is useful for implementing Secure Boot. systemd-boot is the only mainstream bootloader implementing the specification, but GRUB should be able to boot the EFI binary, this commit however doesn't implement the necessary changes to the GRUB config generation logic to boot the Unified Kernel Image.

| | | | | | | | | | | | | | | | | | | | | | | When embedding a rootfs image (e.g. 'rootfs-dir') as a partition we might want to keep the stock fstab for that image. In such a case, use this option to not update the fstab and use the stock one instead. This option allows you to specify which partitions get the fstab updated and which get the stock fstab. The option matches the argument you can pass to wic itself where the same action is performed but for all the partitions. Example: part /export --source rootfs --rootfs-dir=hockeycam-image --fstype=ext4 --label export --align 1024 --no-fstab-update part / --source rootfs --fstype=ext4 --label rootfs --align 1024 (From OE-Core rev: ab4c95af8ecd15dc136194ab761afae756db5803) Signed-off-by: Daniel Gomez <daniel@qtec.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since Linux 5.4 a new read-only filesystem is available, erofs. Compared to squashfs it offers much better read performance with and without compression enabled. It suppports two optional compressors, lz4 and lz4hc. >From the mkfs.erofs man page: EROFS is a new enhanced lightweight linux read-only filesystem with modern designs (eg. no buffer head, reduced metadata, inline xattrs/data, etc.) for scenarios which need high-performance read-only requirements, e.g. Android OS for smartphones and LIVECDs. It also provides fixed-sized output compression support, which improves storage density, keeps relatively higher compression ratios, which is more useful to achieve high performance for embedded devices with limited memory since it has unnoticable memory overhead and page cache thrashing.

* wic: Optimise fstab modification for ext2/3/4 and msdos partitionsPaul Barker2021-01-201-3/+6
| | | | | | | | | | | | | | | | | | The fix for [Yocto #13994] required the rootfs directory to be copied (using hardlinks if possible) when modifying the fstab file under wic. We can optimise this copy away for filesystems where we have the tools to modify the contents of the partition image after it is created. For ext2/3/4 filesystems we have the debugfs tool and for msdos/vfat filesystems we have the mcopy tool. So for any of these filesystems we skip the modification of the fstab file in the rootfs directory (and skip the associated copy unless it is otherwise necessary) and update the contents of fstab directly in the partition image.

* wic: Copy rootfs dir if fstab needs updatingPaul Barker2021-01-201-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default, wic updates the /etc/fstab in the rootfs to include details of additional partitions described in the selected wks file. If this modification is performed in place, other tasks which create an image file from the rootfs directory (e.g. do_image_tar and do_image_ext4) will pick up the modified fstab file which would not be appropriate for those images as they do not include the additional partitions described in the wks file. wic does undo modifications to the fstab file once it has finished creating the filesystem image, however this leaves open a race condition if one of the other tasks reads the contents of the fstab file from the rootfs directory between the point where wic modifies the fstab file and the point where wic restores the files original content. This could be solved by adding a lockfile for tasks which use the rootfs directory to ensure that no other such task is reading the rootfs directory while do_image_wic is running. This would serialize several do_image_* tasks and result in slower builds, especially for large images. Another drawback of this solution is that it is hard to selectively optimise - adding lockfiles to do_image_* tasks would result in these tasks always being serialized even if no fstab modification will take place. An alternative solution is to copy the rootfs directory when fstab needs to be modified. The code to do this in wic already exists as it is needed when including or excluding content in the rootfs. This still results in an impact on build times but the copy uses hardlinks if possible (so little data is actually copied) and we can make selective optimisations to improve things. The rootfs copy will only take place if fstab modification is required (or if it was already needed to include or exclude rootfs content). We can also follow up with further optimisations after this commit. So this second solution is chosen.

* wic: Update pseudo db when excluding content from rootfsPaul Barker2021-01-201-5/+8
| | | | | | | | | | | | | | | | | | | | | | | | To exclude content from the rootfs, wic makes a copy (using hardlinks if possible) of the rootfs directory and associated pseudo db, then removes files & directories as needed. However if these files and directories are removed using the python functions os.remove and shutil.rmtree, the copied pseudo db will not be updated correctly. For files copied from the original rootfs, if hardlinks were used successfully when copying the rootfs this should mean that the relevant inodes can't be reused and so the risk of pseudo aborts should be avoided. However, this logic doesn't apply for directories (as they can't be hardlinked) or for files added via the '--include-path' argument (as they weren't present in the original rootfs) and so there remains some risk of inodes being reused and the pseudo db becoming corrupted. To fix this, use the 'rm' command under pseudo when removing files & directories from the copied rootfs to ensure that the copied pseudo db is updated.

* wic/bootimg-efi: IMAGE_EFI_BOOT_FILES variable added to separate bootimg-efi ↵Khairul Rohaizzat Jamaluddin2020-09-151-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | and bootimg-partition Due to recent changes in bootimg-efi to include IMAGE_BOOT_FILES, when both bootimg-partition and bootimg-efi occur in a single .wks and IMAGE_BOOT_FILES are defined, files listed in IMAGE_BOOT_FILES will be duplicated in both partition. Since IMAGE_BOOT_FILES are crucial for bootimg-partition, but optional for bootimg-efi, hence allowing bootimg-efi to have the option to ignore it. The new variable, IMAGE_EFI_BOOT_FILES, was added to help handle this issue. Its basic usage is the same as IMAGE_BOOT_FILES. Usage example: ${IMGDEPLOYDIR}/${IMAGE_BASENAME}-${MACHINE}.ext4;rootfs.img \ This commit is also squashed with the updated testcase to cover for this change.
