device_allocate(4)

NAME

device_allocate − device_allocate file

SYNOPSIS

/etc/security/device_allocate

AVAILABILITY

The functionality described in this man page is available only if the Basic Security Module (BSM) has been enabled. See bsmconv(1M) for more information.

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 ; alloc ; 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.

alloc This field contains an arbitrary string which controls whether or not a device is allocatable. If the field contains only an asterisk (∗), the device is NOT allocatable. Otherwise, the device may be allocated and deallocated in the normal fashion.

device-exec This is the physical device’s data purge program to be run any time the device is acted on by allocate(1M). 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 administrator.

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 ‘\’.

Leading and trailing blanks are allowed in any of the fields.

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.
