NAME
       device_allocate - device_allocate file

SYNOPSIS
       /etc/security/device_allocate

DESCRIPTION
       The device_allocate file contains mandatory access control information about each physical device. Each device is represented by a one line
       entry of the form:

              device-name;device-type;reserved;reserved;auths;device-exec

       where

       device-name             This is an arbitrary ASCII string naming the physical device. This field contains no embedded white space  or  non-
                               printable characters.

       device-type             This is an arbitrary ASCII string naming the generic device type. This field identifies and groups together devices
                               of like type. This field contains no embedded white space or non-printable characters.

       reserved                This field is reserved for future use.

       reserved                This field is reserved for future use.

       auths                   This field contains a comma-separated list of authorizations required to allocate the device, or  asterisk  (*)  to
                               indicate  that the device is not allocatable, or an '@' symbol to indicate that no explicit authorization is needed
                               to allocate the device.

                               The default authorization is solaris.device.allocate. See auths(1)

       device-exec             This is the physical device's data purge program to be run any time the device is acted on by allocate(1). This  is
                               to  ensure  that  all  usable  data is purged from the physical device before it is reused. This field contains the
                               filename of a program in /etc/security/lib or the full pathname of a cleanup script provided by the system adminis-
                               trator.

       The device_allocate file is an ASCII file that resides in the /etc/security directory.

       Lines in device_allocate can end with a `' to continue an entry on the next line.

       Comments may also be included. A `#' makes a comment of all further text until the next NEWLINE not immediately preceded by a `'.

       White space is allowed in any field.

       The device_allocate file must be created by the system administrator before device allocation is enabled.

       The device_allocate file is owned by root, with a group of sys, and a mode of 0644.

EXAMPLES
       Example 1: Declaring an allocatable device

       Declare  that  physical  device st0 is a type st. st is allocatable, and the script used to clean the device after running deallocate(1) is
       named /etc/security/lib/st_clean.

            # scsi tape
       st0;
            st;
            reserved;
            reserved;
            solaris.device.allocate;
            /etc/security/lib/st_clean

       Example 2: Declaring an allocatable device with authorizations

       Declare that physical device fd0 is of type fd. fd is allocatable by users with the solaris.device.allocate authorization, and  the  script
       used to clean the device after running deallocate(1) is named /etc/security/lib/fd_clean.

            # floppy drive
       fd0;
            fd;
            reserved;
            reserved;
            solaris.device.allocate;
            /etc/security/lib/fd_clean

       Notice  that  making a device allocatable means that you need to allocate and deallocate it to use it (with allocate(1) and deallocate(1)).
       If a device is not allocatable, there will be an asterisk (*) in the auths field, and no one can use the device.
