wic: honor the SOURCE_DATE_EPOCH in case of updated fstab

2022-11-10T14:39:24+00:00

In case user requested to build a binary repeatable package, it's required to honor the SOURCE_DATE_EPOCH environment variable. So forcefully set mtime inside all the routines which modify fstab in case it is updated.

wic/bootimg-efi: use cross objcopy when building unified kernel image

2022-08-31T15:54:17+00:00

We can't rely on the host objcopy knowing how to process target binaries, so use the cross objcopy in the sysroot instead. Also construct the command argument-by-argument as the format expression was getting unwieldy.

wic/plugins/rootfs: Fix permissions when splitting rootfs folders across partitions

2022-05-20T09:08:06+00:00

This patches makes locating the file database containing the file and folder usernames and permissions more reliable. In addition to locating it relative to the partition directory, we also try to locate it relative to the IMAGE_ROOTFS. Prior to this patch, the database was not found when using --rootfs-dir=${IMAGE_ROOTFS}/ in the WIC script, leading to erronous file permissions and ownership.

wic: rawcopy: Add support for packed images

2022-02-16T09:46:29+00:00

Add support for packed images to wic rawcopy handler do minimize disk usage in deploy directory and reuse of packed images between wic and swupdate. Add `unpack` to sourceparams to unpack an bz2, gz and xz archives. Example: part / --source rawcopy --sourceparams="file=core-image-minimal-qemu.ext4.gz,unpack" (From OE-Core rev: 4c97d25791389ece041565981ba3207ce9949a1a) Signed-off-by: Stefan Herbrechtsmeier Signed-off-by: Richard Purdie

wic/bootimg-efi: Add Unified Kernel Image option

2021-10-04T14:03:53+00:00

"A unified kernel image is a single EFI PE executable combining an EFI stub loader, a kernel image, an initramfs image, and the kernel command line. [...] 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.

wic: Add --no-fstab-update part option

2021-08-20T07:53:03+00:00

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 Signed-off-by: Richard Purdie

Use the label provided when formating a dos partition

2021-06-29T21:18:56+00:00

Previously the bootimg-pcbios wic plugin was not respecting the --label option provided from the wks file. The plugin was setting the label to 'boot'. With this fix, the --label option is use. If no option are specified, then the default is 'boot'.

Add support for erofs filesystems

2021-05-31T13:31:01+00:00

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. This commit adds support for three new filesystem targets: erofs: erofs without compression erofs-lz4: erofs with lz4 compresssion enabled erofs-lz4hc: erofs with lz4hc compression enabled (From OE-Core rev: 41dead1ff8ccc49e6cd6e6f5d41a59d164693e0d) Signed-off-by: Richard Weinberger Signed-off-by: Richard Purdie

wic: Optimise fstab modification for ext2/3/4 and msdos partitions

2021-01-20T22:46:18+00:00

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.
