NAME
allocate - device allocation
SYNOPSIS
allocate [-s] [-U uname] device
allocate [-s] [-U uname] -g dev-type
allocate [-s] [-U uname] -F device
The allocate utility manages the ownership of devices through its allocation mechanism. It ensures that each device is used by only one
qualified user at a time.
The device argument specifies the device to be manipulated. To preserve the integrity of the device's owner, the allocate operation is exe-
cuted on all the device special files associated with that device.
The argument dev-type is the device type to be operated on and can only be used with the -g option.
The default allocate operation allocates the device special files associated with device to the uid of the current process.
If the -F option is specified, the device cleaning program is executed when allocation is performed. This cleaning program is found in
/etc/security/lib. The name of this program is found in the device_allocate(4) entry for the device in the dev-exec field.
Only authorized users may allocate a device. The required authorizations are specified in device_allocate(4).
The following options are supported:
-g dev-type Allocates a non-allocated device with a device-type matching dev-type.
-s Silent. Suppresses any diagnostic output.
-F device Reallocates the device allocated to another user. This option is often used with -U to reallocate a specific device to a
specific user. Only a user with the solaris.device.revoke authorization is permitted to use this option.
-U uname Uses the user ID uname instead of the user ID of the current process when performing the allocate operation. Only a user
with the solaris.device.revoke authorization is permitted to use this option.
The following exit values are returned:
non--zero An error occurred.
/etc/security/device_allocate
/etc/security/device_maps
/etc/security/dev/*
/etc/security/lib/*
