/* Allocates an AvbOps instance suitable for use in Android userspace

|
|
*
|
|
* The returned AvbOps has the following characteristics:
|
|
*
|
|
* - The read_from_partition(), write_to_partition(), and
|
|
* get_size_of_partition() operations are implemented, however for
|
|
* these operations to work the fstab file on the device must have a
|
|
* /misc entry using a by-name device file scheme and the containing
|
|
* by-name/ subdirectory must have files for other partitions.
|
|
*
|
|
* - The remaining operations are implemented and never fails and
|
|
* return the following values:
|
|
* - validate_vbmeta_public_key(): always returns |true|.
|
|
* - read_rollback_index(): returns 0 for any roolback index.
|
|
* - write_rollback_index(): no-op.
|
|
* - read_is_device_unlocked(): always returns |true|.
|
|
* - get_unique_guid_for_partition(): always returns the empty string.
|
|
*
|
|
* - The |ab_ops| member will point to a valid AvbABOps instance
|
|
* implemented via libavb_ab/. This should only be used if the AVB
|
|
* A/B stack is used on the device. This is what is used in
|
|
* bootctrl.avb boot control implementation.
|
|
*
|
|
* Free with avb_ops_user_free().
