H06.22 Release Version Update Compendium

2 Operating System
OSS File Privileges (Safeguard V4R11)
• OSS Filesets have a new attribute, RESTRICTEDACCESS, that, when set, restricts the access
privileges of the super ID. When accessing a file in a restricted-access fileset, the super ID
(255,255 in the Guardian environment, 65535 in the OSS environment) is restricted by the
same file permissions and owner privileges as any other user ID: It has no special privileges
unless the executable file started by the super ID has the PRIVSETID file privilege. In this case,
the process started by the super ID can switch to another ID and then access files in
restricted-access filesets as that ID.
• Files have a new file attibute, file privilege, that, when set, can allow executable files and
ordinary DLLs to access files in restricted-access filesets.
For more information about restricted-access filesets and file privileges, see the Open System
Services Management and Operations Guide.
