wic: fix images build in parallel

2020-01-19T13:24:39+00:00

OE wic plugins create temporary file with the index of the line tmp file name. This causes race in case several builds run in time. If source_params['file'] is an absolute path, the cr_workdir prefix is not applied by os.path.join(). So instead it writes to a ".1" file next to the original image - this is outside the WORKDIR and at risk of collision.

wic: Add --include-path argument

2020-01-10T21:18:22+00:00

This option adds the contents of the given path to a partition built with the rootfs source plugin. The path is relative to the directory in which wic is running not the rootfs itself so use of an absolute path is recommended. This option is most useful when multiple copies of the rootfs are added to an image and it is required to add extra content to only one of these copies. This option only has an effect with the rootfs source plugin. (From OE-Core rev: d4cd27a9837426e809190548a83c6c7c76505114) Signed-off-by: Paul Barker Signed-off-by: Richard Purdie

wic: Preserve intermediate files

2020-01-10T21:18:22+00:00

When debugging issues or trying to add new features in wic it's useful to examine the intermediate files created by the tool such as images of the individual partitions. Previously these files were created in a subdirectory of IMGDEPLOYDIR and, deleted by wic itself and then the working subdirectory completely removed at the end of IMAGE_CMD_wic. Instead we should work in a staging directory named build-wic and leave behind intermediate files for analysis if necessary. This has the added benefit of allowing individual partition images to be preserved by adding commands to IMAGE_CMD_wic_append() in an image recipe if needed. This is useful where an update system requires exact sized and pre-formatted partition images for deployment.

isoimage-isohybrid.py: Parameterize ESP partition size

Add "esp_extra_blocks" plugin parameter so that caller may change ESP's free space from the default 100 blocks. (From OE-Core rev: db4be094b0d6741ca4f9e2cbb499fc9c224fa690) Signed-off-by: Haris Okanovic Signed-off-by: Richard Purdie

wic/rawcopy: Support files in sub-directories

2019-10-19T22:18:33+00:00

If the source file is located in a subdirectory of DEPLOY_DIR rawcopy will currently fail in sparse_copy function on open(dst_fname, 'wb'), as the parent directory for destination file does not exist. This patch helps to avoid that by recursively creating parent directories. (From OE-Core rev: 073c435644091c2801e45c6d02afa917de575082) Signed-off-by: Eugene Smirnov Signed-off-by: Richard Purdie

wic/direct: Partition numbering is broken for MBR primary partition #4

2019-10-08T10:22:24+00:00

When wks describes extra partitions that aren't in the partition table (e.g. boot loader) and exactly four primary MBR partitions, the last partition gets added to fstab as partition #5 instead of #4.

wic: Add partition type for msdos partition tables

2019-08-12T15:23:57+00:00

In order to create a msdos partition table disk image that can auto expand after the image is copied to an SD card, wic needs the ability to have a primary partition as the last entry. The desired use case is to be able to create an A/B update partition image scheme with a /var volume that can be auto expanded to the remainder of the SD card at run time. The typical .wks file will look similar to the following: bootloader --ptable msdos part / --source rawcopy --sourceparams="file=u-boot.imx" \ --ondisk mmcblk --no-table --align 1 --size 1 part /boot --source bootimg-partition \ --ondisk mmcblk --fstype=vfat --label boot --active --align 4 --size 16 part / --source rawcopy --sourceparams="file=imx6_boot.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaboot --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaroot --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6_boot.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaboot_b --align 4 --type logical part / --source rawcopy --sourceparams="file=imx6.otaimg" \ --ondisk mmcblk --fstype=ext4 --label otaroot_b --align 4 --type logical part /var --source rawcopy --sourceparams="file=imx6_var.otaimg" \ --ondisk mmcblk --fstype=ext4 --label fluxdata --align 4 Without the patch applied, wic will generate an SD card image that looks like: Disk boot.img: 890940s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 2056s 48001s 45946s primary fat16 lba 2 48008s 132467s 84460s primary ext4 3 132472s 454467s 321996s primary ext4 4 454471s 890939s 436469s extended lba 5 454472s 538931s 84460s logical ext4 6 538936s 860931s 321996s logical ext4 7 860936s 890939s 30004s logical ext4 boot With the patch applied a primary partition can be created at the end of the image which can be expanded to fill the free space on the media where the image has been copied, which looks like: Disk boot.img: 890940s Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End Size Type File system Flags 1 2056s 48001s 45946s primary fat16 lba 2 48007s 860931s 812925s extended lba 5 48008s 132467s 84460s logical ext4 6 132472s 454467s 321996s logical ext4 7 454472s 538931s 84460s logical ext4 8 538936s 860931s 321996s logical ext4 3 860936s 890939s 30004s primary ext4 boot (From OE-Core rev: 56add7cc547e0113cdf980579d1421b14cc233e5) Signed-off-by: Jason Wessel Signed-off-by: Richard Purdie

wic/plugins: Source that support both EFI and BIOS

2019-07-23T21:26:28+00:00

Add a source plugin that support both EFI and legacy PC-Bios. While using this plugin, both bootloaders configurations reside in the same /boot partitions. This plugin has very little code : to avoid code duplication, we simply re-import bootimg-pcbios and bootmg-efi source and call both their SourcePlugin methods.

wic: Fix (again) partition files UIDs on multi rootfs images

2019-07-19T07:41:40+00:00

Commit 450335ba5e73a375eb9932b4c4cf37979640dbfc copies the pseudo database to the working directory in order to have ownership information when the filesystem is generated. Unfortunately this does not work anymore. The filenames on the database are absolute and there is no information about the new directory. Instead of fixing the database, we could redo a bit the way we patch the fstab file. Now I am saving the old contents of fstab, modifying the file and then reverting the changes on exit. This is faster than the previous approach, although it can cause indeterminism if the application is killed before finishing.
