Share actions
=============

Share actions include granting or revoking share access, listing the
available access rules for a share, explicitly updating the state of a
share, resizing a share and un-managing a share.

As administrator, you can reset the state of a share and force-
delete a share in any state. Use the ``policy.yaml`` file to grant
permissions for this action to other roles.

You can set the state of a share to one of these supported states:

- ``available``

- ``error``

- ``creating``

- ``deleting``

- ``error_deleting``

If API version 1.0-2.6 is used then all share actions, defined
below, should include prefix ``os-`` in top element of request
JSON's body.

For example: {"access_list": null} is valid for v2.7+. And {"os-
access_list": null} is valid for v1.0-2.6


Grant access
~~~~~~~~~~~~

All manila shares begin with no access. Clients must be provided with
explicit access via this API.

To grant access, specify one of these supported share access levels:

- ``rw``. Read and write (RW) access.

- ``ro``. Read-only (RO) access.

You must also specify one of these supported authentication
methods:

- ``ip``. Authenticates an instance through its IP address.
  The value specified should be a valid IPv4 or an IPv6 address,
  or a subnet in CIDR notation.
  A valid format is ``X:X:X:X:X:X:X:X``, ``X:X:X:X:X:X:X:X/XX``,
  ``XX.XX.XX.XX``, or ``XX.XX.XX.XX/XX``, etc. For
  example ``0.0.0.0/0`` or ``::/0``.

.. important::

  IPv6 based access is only supported with API version 2.38 and beyond.

- ``cert``. Authenticates an instance through a TLS certificate.
  Specify the TLS identity as the IDENTKEY. A valid value is any
  string up to 64 characters long in the common name (CN) of the
  certificate. The meaning of a string depends on its
  interpretation.

- ``user``. Authenticates by a user or group name. A valid value is
  an alphanumeric string that can contain some special characters
  and is from 4 to 255 characters long.
