Fixes for SQL security

LP bugs fixed:

1392805 – DB_ROOT incorrectly gets “NOT AUTHORIZED” messages

1398546 – revoke priv from role fails when view is present

1401233 – USAGE privilege not checked when creating procedure (and

revoking privileges)

1403995 – Update stats failures due to schema PUBLIC_ACCESS_SCHEMA

1401683 – (Partial) DDLoperations see error 8841 about transaction

started by SQL

Regressions updated:

catman1/TEST135 & EXPECTED138

catman1/EXPECTED138 (fix in common/ComUser.cpp)

Bug descriptions:

1392805:

Changed create view code to allow DB__ROOT to create views. Some

reorganization required to make sure create view sets the updatatable

and insertable privilege correctly. This also fixed the problem where

the incorrect privileges were set when created by DB__ROOT.

Sqlcomp/CmpSeabaseDDLview.cpp

Sqlcomp/PrivMgrPrivileges.h (sets default privileges)

1398546:

The check to see if the "select" privilege is still in existence needed

to be changed until after all the privilege descriptors were analyzed.

Sqlcomp/PrivMgrPrivileges.cpp (gatherViewPrivileges)

Sqlcomp/PrivMgrDesc.h

1401233:

Missing checks at create UDR and revoke USAGE privilege were added.

Sqlcomp/CmpSeabaseDDLroutine.cpp

Sqlcomp/PrivMgrMD (getUdrsThatReferenceLibraries)

Sqlcomp/PrivMgrPrivileges.cpp (dealWithUdrs)

1403995:

This is a critical case QA filed because the PUBLIC_ACCESS_SCHEMA does

not exist for temporary sample tables during Update Statistics. If the

PUBLIC_ACCESS_SCHEMA does not exist, the temporary sample table will be

created in the same schema as the source table. Also fixed an issue for

private schemas not owned by DB__ROOT to make the histogram table's

owner the current user.

ustat/hs_cli.cpp

ustat/hs_globals.cpp

1401683:

There are several 8841 issues being detected. This is a fix for one of

them related to Update Statistics where an embedded "get" statement

causes a transaction to be started in a child tdm_arkcmp process. The

fix is to not automatically start a transaction for the get request.

main branch.

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

introduced.

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.
