Turned on privilege features, reorg'd PrivMgr code


For GRANTED BY -> showddl now displays the GRANTED BY clause when

--> the current user is not the object owner and

--> the current user is not DB ROOT

added object_owner and schema_owner to the SeabaseLibraryDesc




CmpSeabaseDDLtable.cpp ->getSeabaseLibraryDesc

added object owner in calls to PrivMgrPrivileges::getPrivTextForObject




Changed object grant and revoke to store the list of privileges associated

with the object and columns in the PrivMgrPrivileges class.

--> added new methods generateObjectRowList and generateColumnRowList,

changed the destructor to remove these lists, changed code to call

these new methods, and removed extra I/Os

--> removed member trafMetadataLocation_ (it is already stored in parent)

For WITH GRANT OPTION clause at GRANT time:

--> added checks at grant time to:

--> check for potential circular grants (error 1036)

--> added new method getTreeOfGrants to get list of grantors

that have previously granted to the current grantee

For GRANT OPTION FOR clause at REVOKE time:

--> changed error messages returned to be more meaningful

--> moved and activated call checkRevokeRestrict after call to


Added new columns to the COLUMN_PRIVILEGES and SCHEMA_PRIVILEGES tables

to include the object_name, grantor_name, and grantee_name to match


Reorganized the contents of PrivMgr files:

--> PrivMgr document exists that describes the .h/.cpp structure

--> Added new files PrivMgr.h/PrivMgr.cpp that describes the parent

class for all PrivMgr requests

--> moved existing defines, classes, etc around to match the PrivMgr


Fixed a couple of issues:

--> Fixed a bug in initialize authorization where the WGO was not set up

correctly for UDR's

--> Fixed a bug in PrivMgrObject::selectAllWhere where an error condition

was not returned

--> Fixed a bug in seabaseGrantRevoke where the incorrect object type was

sent for views

--> Fixed a bug in update statistics privilege checking that was not

handling HBase tables correctly

Added two regression tests (skipped until catman1 test directory is split up)

--> TEST132 - tests for privilege checking on libraries, populate index,

showddl, invoke, update statistics, and showstats

--> TEST140 - tests for WITH GRANT OPTION and GRANTED by option

Fixed expected result for catman1/TEST137

The following Launchpad bugs are fixed in this change:

Bug 1370749: Now using MAX_USERNAME_LEN instead of hardcoded value

Bug 1413760: CREATE TABLE LIKE was failing in some circumstances because

SHOWDDL was including the BY clause. Ownership rules changes in

CREATE TABLE changed when ANSI schemas was implemented, so the BY clause

is no longer needed.

Bug 1392107: Privileges granted on a view are no longer lost if the

view is replaced via CREATE OR REPLACE VIEW.

Bug 1370740: A potential memory corruption problem is now avoided

by reworking the authorization name lookup functions.

Bug 1413767: Previously DROP SCHEMA CASCADE would fail to drop a

table with an IDENTITY column.

Bug 1413758: Previously DROP TABLE CASCADE did not drop nested views.

Bug 1412891: Previously DROP TABLE CASCADE failed if a dependent object

contained a delimited name.

Changes are present for 1392086, but the work is not yet completed.

This problem is related to roles and security keys.

Code changes are also present for giving ownership of an object to

another authorization ID, but these changes are not complete. A

description of

the changes is included.

The GIVE command transfers ownership of a SQL item from one

authorization ID to another. Implemented in this delivery is


GIVE ALL transfers all SQL items owned by an authorization ID to another

authorization ID. Current or new owner can be a user or a role. The

GIVE ALL command requires the ALTER privilege.


GIVE SCHEMA behavior depends on the type of schema and whether RESTRICT

or CASCADE is specified. For private schemas, all the objects in the

schema are given, as well as the schema itself. For shared schemas,

only the

schema is given, unless the CASCADE option is specified. In that case,


of all the objects in the shared schema is given to the new owner. Use


the CASCADE option requires the ALTER_SCHEMA privilege. Otherwise, GIVE

SCHEMA only requires the user to be the owner of the schema.


NOTE: RESTRICT and CASCADE are not applicable to private schemas and are


GIVE OBJECT is added to the syntax but is not implemented and may not

be implemented.

A more detailed blueprint will be provided prior to the final delivery

of GIVE.

Authorization checks for DDL & utilities

Fixed issues from code comments.

LOAD/UNLOAD authorization checks:

Code was added during code generation to make sure user has privileges,

if the user had necessary privileges, then the EXEUTIL parser flag is

turned on to avoid further privilege checks. When load/unload

completes, the parser flag is reset.

Update/showstats Statistics authorization checks:

Added a new error message

Changed hs_globals to support a new isAuthorized method and store

parser flags when class is instantiated and reset them when done

Changed hs_cli.cpp to use new IF NOT EXISTS syntax when creating

histogram tables, make owner of histogram tables DB__ROOT

(will need to adjust when schema privileges happen), and clean up

CreateHistTables method to remove old authorization mechanism

Changed hs_update.cpp which controls the update and showstats operation

to add authorization checks

Purgedata and populate index changes:

Changed CmpSeabaseDDLcommon.cpp to check privileges for purgedata

Changed CmpSeabaseDDLindex.cpp to check privileges for popindex

Additional component privileges and checks:

Added support for new component privileges in PrivMgrMD.h/.cpp

Added support for MANAGE_COMPONENTS

Added support for CREATE_INDEX and DROP_INDEX component privs

Fixes from last delivery that were postponed:

Context.cpp - fix for previous code review

CmpSeabaseDDLtable - added calls to deallocEHI

PrivMgrMD - fixed wording in a comment

Miscellaneous changes:

ComUser - added new convenience method - isRootUserID()

NATable.cpp (setupPrivInfo) to always set up privInfo_ and to call

the embedded compiler while extracting privileges

Privilege adjustments to take advantage of privInfo stored in NATable:

Added code to mark and rewind errors in diags.

Fix for LP bug 1392895

Security changes to support authorization

Added support for authorization commands:

- initialize authorization [, drop]

- create/drop roles

- register/unregister components

- create/drop component operations

- grant/revoke object privileges

- grant/revoke role privileges

- grant/revoke component privileges

- updates to GET and SHOWDDL statements

- checking of privileges for DML requests

- checking of privileges for DDL requests

- regression tests added to catman1 library

Fixed a testware problem in catman1 TEST135 and TEST139

Fixed a parser problem introduced by compGeneral/TESTTOK2 which was recently


More details:

This delivery was part of code worked on by many people for several

months on a remote branch. This team held bi-weekly meetings

for several months to design and implement these features. These

meetings also included extensive code reviews.

The security features which include authentication (which was delivered

in June) and authorization is turned off by default. The

traf_authentication_setup script located in $MY_SQROOT/sql/scripts needs

to be run to enable both authentication and authorization. This

procedure is described on the Trafodion Twiki page and will be updated once this

delivery completed to include authorzation.

Delivery updates:

Updated traf_authentication_setup to return consistent error messages

and added a comment to ComSmallDefs.h to address a buf size issue for

metadata tables.
