Enhanced Tacker Policy Usage Guide

Overview

The default Tacker API policy only supports whether the user can access the API, but does not determine whether the users can access the resource on which the API call operates.

Enhanced Tacker Policy enables Users to get finer-grained access control based on user and VNF information for API resources.

This document describes how to use Enhanced Tacker Policy in Tacker.

Introduction to enhanced tacker attributes

Enhanced Tacker Policy function currently supports three enhanced attributes: area, vendor, and tenant.

  • area: Area attribute is an area-region pair. The value of this attribute is a string in the format of “area@region”. This attribute describes the area where VIM or VNF is located.

  • vendor: Vendor attribute is the name of the vendor. It is defined in the definition file of VNF package. VNF obtains this attribute from VNF package.

  • tenant: Tenant attribute is the name of the tenant. Tacker Antelope version only supports the namespace of CNF. The tenant of VNF will be supported in future releases.

Enable Enhanced Tacker Policy

Enhanced Tacker Policy is disabled by default in Tacker. For it to work, user needs to find enhanced_tacker_policy in tacker.conf and change its value to True. If not found, please add it yourself.

$ vi /etc/tacker/tacker.conf
...
[oslo_policy]
enhanced_tacker_policy = True
...

Configure Enhanced Policy Rules

The oslo.policy [1] supports the function to compare API attributes to object attributes. Based on this function, Enhanced Tacker Policy function currently supports three enhanced tacker attributes: area, vendor, and tenant.

"get_vim" : "area:%(area)s"
"os_nfv_orchestration_api:vnf_packages:show" : "vendor:%(vendor)s"
"os_nfv_orchestration_api:vnf_instances:show" : "tenant:%(tenant)s"

Take the area attribute as an example, the area string before the colon is an API attribute, namely the area of the API user. It is compared with the area of the object (in this case, a VNF instance). More precisely, it is compared with the area field of that object in the database. If the two values are equal, permission is granted.

For the policy rule configuration used in this usage guide, please refer to the Sample policy.yaml file chapter in the Appendix.

Create user with special roles

Users need to define special roles with the following naming rules to represent users with access rights to corresponding resources. For example, a user with a role of VENDOR_company-a has permission to access resources whose vendor attribute is company-a. This is because in implementation, Tacker will convert special roles into user attributes according to the following conversion rules for attribute comparison.

Special Roles’ Naming Rules

Enhanced Tacker Policy defines the following naming rules for special roles. Admin user need to create special roles according to these naming rules, otherwise Tacker will not correctly convert these special roles into user attributes.

  1. The role name consists of three parts: prefix + “_” + [attribute value/special value]

  2. Supported prefixes, attribute values and special values are shown in the following table:

    Prefix

    Attribute value

    Special value

    Sample

    AREA

    area value

    all@all, all@{region_value}

    AREA_tokyo@japan, AREA_all@all, AREA_all@japan

    VENDOR

    vendor value

    all

    VENDOR_company_a, VENDOR_all

    TENANT

    tenant value

    all

    TENANT_default, TENANT_all

    Note

    As “all” is treated as a special value, the above attribute of resource cannot use “all” as the attribute value.

Conversion rules

In Tacker implementation, Tacker converts these special roles into API attributes and provide them to Tacker policy. The conversion follows the following rules:

  1. For ordinary attribute values, they will be directly converted to user attribute values.

    Prefix

    Attribute Name

    Sample (special role -> user attribute value)

    AREA

    area

    AREA_tokyo@japan -> {“area”: [”tokyo@japan”]}

    VENDOR

    vendor

    VENDOR_company-a -> {“vendor”: [“company-a”]}

    TENANT

    tenant value

    TENANT_default -> {“tenant”: [“default”]}

  2. For special value in Enhanced Tacker Policy, the corresponding attribute value of resource will be assigned to user.

    Prefix

    Attribute Name

    Special Value

    Sample (resource attribute -> user attribute)

    AREA

    area

    all@all

    {“area”: “tokyo@japan”} -> {“area”: [”tokyo@japan”]}

    AREA

    area

    all@{region_value}

    same region value:

    {"area": "tokyo@japan"} -> {"area": ["tokyo@japan"]}

    different region value:

    any -> {"area": []}

    VENDOR

    vendor

    all

    {“vendor”: “vendor_company-a”} -> {“vendor”: [“company-a”]}

    TENANT

    tenant value

    all

    {“tenant”: “default”} -> {“tenant”: [“default”]}

Create users with special roles

In this user guide, user creates three end-users with admin user:

  • user-a with special roles is used as the experimental group.

  • user-b without special roles is used as the control group.

  • user-manager with special roles and manager role as manager.

Create resources with enhanced tacker attributes

This section describes how to create resources with enhanced tacker attributes, using examples.

Register vim with area attribute

When registering a vim, users can specify area attribute for the vim. This is achieved by putting the area attribute into the extra field of the vim configuration file. Please refer to VIM Management [2] for how to register a vim.

Warning

It is highly recommended that users who performs the VIM registration is isolated from users who call VNF LCM APIs. Otherwise, users can ignore area attribute if VIM by overwriting.

  1. Register an OpenStack VIM with area attribute tokyo@japan.

    Sample vim_config.yaml file for OpenStack VIM:

    auth_url: 'http://192.168.10.115/identity/v3'
username: 'nfv_user'
password: 'devstack'
project_name: 'nfv'
project_domain_name: 'default'
user_domain_name: 'default'
cert_verify: 'True'
extra:
    area: tokyo@japan

    Register OpenStack VIM:

    $ openstack vim register --config-file ./vim_config.yaml \
    --description 'openstack vim in nfv' \
    openstack-tokyo@japan

Create VNF package with vendor attribute

The vendor attribute of the VNF package resource comes from the provider field defined in Definitions/vnfd_top.yaml of the VNF package. To create a VNF package with a specified vendor attribute, users need to modify the provider attribute to vendor. Please refer to VNF Package [3] for how to make zip file and create VNF packages. This chapter only gives a sample of configuration files that need to be modified in VNF package.

  1. Set the provider in Definitions/vnfd_top.yaml to company-a.

    tosca_definitions_version: tosca_simple_yaml_1_2

imports:
  - etsi_nfv_sol001_common_types.yaml
  - etsi_nfv_sol001_vnfd_types.yaml
  - sample_vnfd_types.yaml
  - sample_vnfd_df_simple.yaml

  2. Set the provider in Definitions/vnfd_types.yaml to company-a.

    tosca_definitions_version: tosca_simple_yaml_1_2

Create & Instantiate VNF with vendor, area and tenant attributes

Create VNF with vendor attribute

The vendor attribute of the VNF comes from the provider attribute of the VNF package. Therefore, users only need to use the VNF package with the specified provider attribute to create a VNF with the specified vendor attribute.

The following is an example of creating a VNF with the specified vendor attribute.

Create a VNF with vnfd_id:

$ openstack vnflcm create <vnfd_id>

Instantiate VNF on VIM with area attributes

The area attribute of the VNF comes from the used vim. In other words, you need to specify a VIM in the area where you want to instantiate a VNF.

For VNF LCM API version 1, please refer to [4] to instantiate VNF. Below are two samples of <param-file>.

  1. If <param-file> contains the vimConnectionInfo parameter, the area attribute comes from vim in it.

  2. If <param-file> doesn’t contains the vimConnectionInfo parameter, the default vim is used and area attribute comes from it.

}

For VNF LCM API version 2, please refer to [4] to instantiate VNF. Below are two samples of <param-file>.

  1. If the vim in the vimConnectionInfo parameter of <param-file> is an existing vim in the DB, the vendor attribute of the instantiated VNF comes from this vim.

Instantiate CNF with tenant attribute

In Tacker Antelope verison, only CNF has the tenant attribute. When instantiating CNF, the tenant attribute of CNF is specified by the namespace in the additionalParams field of <param-file>.

Usage of APIs supporting Enhanced Tacker Policy

This section takes the VIM Management API as an example to introduce the API calls that support Enhanced Tacker Policy. You can find a list of APIs that support Enhanced Tacker Policy and the enhanced tacker attributes supported by each API in Tacker APIs that support Enhanced Tacker Policy.

GET individual resources

Users with special roles have permission to access corresponding resources. For example, user-a who has the role of AREA_tokyo@japan has permission to access the VIM with area attribute tokyo@japan. user-b who does not have the role of AREA_tokyo@japan does not have permission to access the VIM with area attribute tokyo@japan. Here take Show VIM as an example.

user-a shows VIM whose area attribute is tokyo@japan, and it succeeds.

The request you have made requires authentication. (HTTP 401) (Request-ID: req-4875a3b8-b553-439b-a837-5940737f672a)

Users can use the manager role to distinguish between reference APIs and operating APIs. This is an existing function of oslo.policy, and here is just a suggested usage scenario.

user-a has no manager role and cannot delete VIM.

$ openstack vim delete 95f633de-d2d1-4d90-90f7-0f3839369ff2
Unable to delete the below vim(s):
Cannot delete 95f633de-d2d1-4d90-90f7-0f3839369ff2: The resource could not be found.

user-manager has the role of manager and can delete VIM.

$ openstack vim delete 95f633de-d2d1-4d90-90f7-0f3839369ff2
All specified vim(s) deleted successfully

LIST resources

For APIs that list resources, Enhanced Tacker Policy acts as a filter. That is, the list operation only lists resources that the user has permission. Here take List VIM as an example.

The user-a only has permission to access the VIM with area attribute tokyo@japan. Therefore, user-a can only list the VIM with area attribute tokyo@japan.

$ openstack vim list
+--------------------------------------+------------------------+----------------------------------+------------+------------+-----------+

+--------------------------------------+------------------------+----------------------------------+------------+------------+-----------+

The user-b does not have access to any VIM with the area attribute, so the list is empty when performing the List VIM operation.

$ openstack vim list
(No output.)

The user-manager has access rights to all resources. It can list all resources.

$ openstack vim list

Limitations

  • As the resources created in the previous version of Tacker may not have enhanced policy attributes, if the enhanced policy attributes are used as comparison attributes in the policy rule, this rule will prevent users from accessing those resources without these attributes as the comparison result is always false.
