[ http://issues.apache.org/jira/browse/DERBY-1330?page=all ]
Mamta A. Satoor updated DERBY-1330:
-----------------------------------
Description:
Additional work needs to be done for grant/revoke to make sure that only users
with required privileges can access various database objects. In order to do
that, first we need to collect the privilege requirements for various database
objects and store them in SYS.SYSREQUIREDPERM. Once we have this information
then when a user tries to access an object, the required SYS.SYSREQUIREDPERM
privileges for the object will be checked against the user privileges in
SYS.SYSTABLEPERMS, SYS.SYSCOLPERMS and SYS.SYSROUTINEPERMS. The database object
access will succeed only if the user has the necessary privileges.
SYS.SYSTABLEPERMS, SYS.SYSCOLPERMS and SYS.SYSROUTINEPERMS are already
populated by Satheesh's work on DERBY-464. But SYS.SYSREQUIREDPERM doesn't have
any information in it at this point and hence no runtime privilege checking is
getting done at this point.
