## Authorization Checks

Many methods and operations offered by udisks requires the calling user to be sufficiently authorized. Whether the user is authorized is checked using polkit allowing the administrator to configure fine-grained permissions via polkit authorization rules.

There is not necessarily a one-to-one relationship between D-Bus methods and polkit actions - typically the relationship is more complicated and depends on both the context of the process invoking the method, the object the method is acting on and possibly more factors. For example, the Filesystem.Mount() method call may check that the caller is authorized for one of the four actions org.freedesktop.UDisks2.filesystem-mount, org.freedesktop.UDisks2.filesystem-mount-system, org.freedesktop.UDisks2.filesystem-mount-other-seat or org.freedesktop.UDisks2.filesystem-mount-fstab depending on circumstances.

Often there will be two polkit actions for one operation - one for so-called “system devices” and one for non-system devices. In this context “system device” refers to the value of the Block:HintSystem D-Bus property and is normally only `TRUE` for devices not considered “removable” (devices considered removable include USB attached storage, Flash media and optical drives). See udisks(8) for how to control if a device is considered a system device.

The polkit actions are not considered stable and may change from release to release so administrators should take notice when upgrading from one version of udisks to another. For example, polkit authorization rules may need to be updated to match an updated policy.

See Table 1, “Known polkit variables” for the variables that can be used to assist in determining if the caller is authorized (note that each variable may not be set for request). For example, a polkit authorization rule for any of the org.freedesktop.UDisks2.filesystem-mount* actions can use the `device` variable to determine if the caller is authorized to mount a specific block device.

Table 1. Known polkit variables

key | value
--- | ---
`device` | If the object is a block device, this property is set to the value of the Block:PreferredDevice property. If set, this is guaranteed to be a device file, for example “/dev/vg_lucifer/lv_root” or “/dev/sda1”. If the object is not a block device, this is not set.

`drive`

Like the `device` variable, but if the object is also a drive, this variable includes Vital Product Data about the drive such as the vendor and model identifiers (if available), for example “INTEL SSDSA2MH080G1GC (/dev/sda1)”. Otherwise is just set to the same value as `device`. If the object is not a block device, this is not set (it is however set if the object is a block device but not a drive).

`drive.wwn` | If the object is a drive (or a block device that is part of a drive), this is set to the value of the Drive:WWN property.
`drive.serial` | If the object is a drive (or a block device that is part of a drive), this is set to the value of the Drive:Serial property.
`drive.vendor` | If the object is a drive (or a block device that is part of a drive), this is set to the value of the Drive:Vendor property.
`drive.model` | If the object is a drive (or a block device that is part of a drive), this is set to the value of the Drive:Model property.
`drive.revision` | If the object is a drive (or a block device that is part of a drive), this is set to the value of the Drive:Revision property.
`drive.removable` | If the object is a drive (or a block device that is part of a drive), this is set to the string “true” only if the value of the Drive:Removable property is `TRUE`.
`drive.removable.bus` | If the object is a drive (or a block device that is part of a drive), this is set to the value of the Drive:ConnectionBus property. This variable is set only if the value of the Drive:Removable property is `TRUE`.
`drive.removable.media` | If the object is a drive (or a block device that is part of a drive), this is set to the value of the Drive:MediaCompatibility property. This variable is set only if the value of the Drive:Removable property is `TRUE`.
`id.type` | If the object is a block device, this property is set to the value of the Block:IdType property.
`id.usage` | If the object is a block device, this property is set to the value of the Block:IdUsage property.
`id.version` | If the object is a block device, this property is set to the value of the Block:IdVersion property.
`id.label` | If the object is a block device, this property is set to the value of the Block:IdLabel property.
`id.uuid` | If the object is a block device, this property is set to the value of the Block:IdUUID property.
`partition.number` | If the object is a partition, this property is set to the value of the Partition:Number property.
`partition.type` | If the object is a partition, this property is set to the value of the Partition:Type property.
`partition.flags` | If the object is a partition, this property is set to the value of the Partition:Flags property.
`partition.name` | If the object is a partition, this property is set to the value of the Partition:Name property.
`partition.uuid` | If the object is a partition, this property is set to the value of the Partition:UUID property.
