/* Allocates an AvbOps instance suitable for use in Android userspace |
|
* on the device. Returns NULL on OOM. |
|
* |
|
* 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(). |
