RSBAC Changes in recent versions
--------------------------------

1.0.3:  - Target DEV added to file/dir utilities. rsbac_dev_menu added.
          Now devices can get their own attributes based
          on major/minor numbers, not only based on their file representations
          in /dev, which can be easily duplicated.
        - Attribute object_type removed from rsbac_fd_menu, was not used anyway
          and removed in rsbac/kernel.
        - attr_back_fd added. (Recursive) backup of all attribute values for
          those files/dirs given in command line. Only non-default values are
          saved. Output script file contains all attr_set_file_dir calls needed
          to restore.
        - Similar attr_back_user and attr_back_dev added.
        - Attributes log_array_low and log_array_high added to file/dir/dev
          utils.
        - Administration menu for (file/dir/dev X request) log levels
          added to rsbac_fd_menu and rsbac_dev_menu.
        - Command line utils also got log_level special options.

1.0.4:  - Attributes mac_trusted_for_user, ms_sock_trusted_tcp/udp added to
          FILE utils
        - Attributes ms_sock_trusted_tcp/udp added to process utils
        - Attributes ms_trusted, ms_sockbuf, ms_str_nr, ms_str_offset,
          ms_scanned added to ipc utils
        - Attribute object_type removed from ipc utils, as in kernel - was
          IPC all the time anyway
        - Adjusted syscall return value interpretation to 2.1 kernels

1.0.5:  - rsbac_write added to call sys_rsbac_write = save attributes now
        - mac_wrap added to start a program with changed maximum security
          level (not the process owner's), e.g. from inetd
        - user_aci.sh added to set default roles with maintenance kernel

1.0.6:  - Changed rsbac_fd_menu and rsbac_process_menu to tristate
          ms_trusted
        - Added attribute ff_flags with bit values to rsbac_fd_menu
        - Added rsbac_check to call sys_rsbac_check(), which checks
          attribute consistency

1.0.7:  - Added inherit values to security_level, object_category and
          data_type in rsbac_fd_menu
        - Added menu item to change between effective and real attribute
          values
        - Added support for different screen sizes - if LINES and COLUMNS
          are exported from bash (e.g. in /etc/profile)
