------------------------------------------
Summary: List permissions output for superuser after grant command
is not correct
Key: CASSANDRA-18018
URL: https://issues.apache.org/jira/browse/CASSANDRA-18018
Project: Cassandra
Issue Type: Bug
Components: Feature/Authorization
Reporter: Shailaja Koppu
Running local Cassandra with below config:
authenticator: PasswordAuthenticator
authorizer: CassandraAuthorizer
role_manager: CassandraRoleManager
network_authorizer: CassandraNetworkAuthorizer
Created a super user and then ran *Grant select* command on a keyspace.
shaadmin1@cqlsh> CREATE USER 'shaadmin1c1' WITH PASSWORD 'shaadmin1c1'
SUPERUSER;
shaadmin1@cqlsh:system_auth> grant select on testk1.t1 to shaadmin1c1;
shaadmin1@cqlsh:system_auth> alter role shaadmin1c1 with access to all
datacenters;
After this, list permissions command showing only select permission for that
role on the resource.
shaadmin1c1@cqlsh> list all permissions of shaadmin1c1;
role | username | resource | permission
-------------+-------------+-------------------+------------
shaadmin1c1 | shaadmin1c1 | <table testk1.t1> | SELECT
Row in role_permissions table:
role | resource | permissions
-------------+-------------------+--------------------------------------------------------------
shaadmin1c1 | data/testk1/t1 |
\{'SELECT'}
But insert command by that role on the resource is successful because role is a
super user
shaadmin1c1@cqlsh> insert into testk1.t1 (c1, c2) values ('a', 1);
shaadmin1c1@cqlsh> select * from testk1.t1 ;
c1 | c2
----+----
a | 1
(1 rows)
The problem is, output of list permissions command, which indicates only select
permission on the resource is misleading. I think list command need to be fixed
to show all permissions super user has on the resource. Also grant command for
a super user can be either a no-op or throw error, because the role already
have requested permissions.
Documentation also misleading:
{quote}True automatically grants AUTHORIZE, CREATE and DROP permission on ALL
ROLES.
Superusers can only manage roles by default. To manage other resources,
{color:#FF0000}you must grant the permission set to that resource. **
{color}For example, to allow access management for all keyspaces: {{GRANT ALL
PERMISSIONS ON ALL KEYSPACES TO }}{{{}*role_name*{}}}.{quote}
