wic: rootfs: Combine path_validation in one function

2020-04-26T13:00:50+00:00

Combine all the common path validation in a function to avoid code duplication. Cc: Paul Barker (From OE-Core rev: ebd12b10d17db0b4176b0188407d7e9b8420eab1) Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Richard Purdie

wic: root: Add an opt. destination on include-path

2020-04-26T13:00:50+00:00

Allow specifying an optional destination to include-path and make the option aware of permissions and owners. It is very useful for making a partition that contains the rootfs for a host and a target Eg: / -> Roofs for the host /export/ -> Rootfs for the target (which will netboot) Although today we support making a partition for "/export" this might not be compatible with some upgrade systems, or we might be limited by the number of partitions. With this patch we can use something like: part / --source rootfs --fstype=ext4 --include-path core-image-minimal-mtdutils export/ --include-path hello on the .wks file.

wic: Continue if excluded_path does not exist

2020-04-26T13:00:50+00:00

If an excuded path does not exist, continue without an error. This allows to seamleasly reuse .wks among different projects. Eg: part / --source rootfs --fstype=ext4 --exclude-path=opt/private_keys Where /opt/private_keys in only populated by some of the image.bb files.

wic: Add --change-directory argument

2020-04-26T13:00:50+00:00

This option allows to specify which part of a rootfs is going to be included, the same way the -C argument on tar. Thanks to this option we can make sure the permissions and usernames on the target partition are respected, and also simplify the creation of splitted partitons, not neeting to invoke external vars or using .wks.in files. Eg: part / --source rootfs --ondisk sda --fstype=ext4 --exclude-path=etc/ part /etc --source rootfs --fstype=ext4 --change-directory=etc Cc: Paul Barker (From OE-Core rev: 2265d089a58e1f78f26d623ee667c420cb1c3bd4) Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Richard Purdie

wic: Fix permissions when using exclude or include path

2020-04-26T13:00:50+00:00

When parameters include_path or exclude_path are passed to the rootfs plugin, it will copy the partition content into a folder and make all the modifications there. This is done using copyhardlinktree(), which does not take into consideration the content of the pseudo folder, which contains the information about the right permissions and ownership of the folders. This results in a rootfs owned by the user that is running the wic command (usually UID 1000), which makes some rootfs unbootable. This bug can be easily triggerd with the following .wks part / --source rootfs --fstype=ext4 --exclude-path=home And this sequence: $ wic create test-permissions -e core-image-minimal -o test/ $ sudo mount test/test-permissions-202004080823-sda.direct.p1 /mnt $ ls -la /mnt/etc/shadow To fix this we copy the content of the pseudo folders to the new folder and modify the pseudo database using the "pseudo -B" command. If the rootfs is not a rootfs generated by bitbake a warning is shown making the user aware that the permissions on the target might not match what he expects. WARNING: /tmp/test/../pseudo folder does not exist. Usernames and permissions will be invalid Cc: Paul Barker (From OE-Core rev: fd739c15cdba221d9d497d3402b7d929c0be2ca4) Signed-off-by: Ricardo Ribalda Delgado Signed-off-by: Richard Purdie

wic: Add --embed-rootfs argument

2020-04-06T15:45:11+00:00

This option adds the content of a rootfs on a specific location on the rootfs. It is very useful for making a partition that contains the rootfs for a host and a target Eg: / -> Roofs for the host /export/ -> Rootfs for the target (which will netboot) Although today we support making a partition for "/export" this might not be compatible with some upgrade systems, or we might be limited by the number of partitions. With this patch we can use something like: part / --source rootfs --embed-rootfs target-image /export --embed-rootfs target-image2 /export2 on the .wks file.

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
