Functions ¶

func Mount ¶

func Mount(ctx context.Context, device uint32, target string, mappingInfo *prot.DeviceMappingInfo, verityInfo *prot.DeviceVerityInfo, securityPolicy securitypolicy.SecurityPolicyEnforcer) (err error)

Mount mounts the pmem device at `/dev/pmem<device>` to `target` in a basic scenario. If either mappingInfo or verityInfo are non-nil, the device-mapper framework is used to create linear and verity targets accordingly. If both are non-nil, the linear target is created first and used as the data/hash device for the verity target.

`target` will be created. On mount failure the created `target` will be automatically cleaned up.

Note: For now the platform only supports readonly pmem that is assumed to be `ext4`.

Note: both mappingInfo and verityInfo can be non-nil at the same time, in that case linear target is created first and it becomes the data/hash device for verity target.

func Unmount ¶

func Unmount(ctx context.Context, devNumber uint32, target string, mappingInfo *prot.DeviceMappingInfo, verityInfo *prot.DeviceVerityInfo, securityPolicy securitypolicy.SecurityPolicyEnforcer) (err error)

Unmount unmounts `target` and removes corresponding linear and verity targets when needed
