NAME
mkdevalloc - Make device_allocate entries SYNOPSIS
/usr/sbin/mkdevalloc DESCRIPTION
The mkdevalloc command writes to standard out a set of device_allocate(4) entries describing the system's frame buffer, audio and removable media devices. The mkdevalloc command is used by the init.d(4) scripts to create or update the /etc/security/device_allocate file. Entries are generated based on the device special files found in /dev. For the different categories of devices, the mkdevalloc command checks for the following files under /dev: audio /dev/audio, /dev/audioctl, /dev/sound/... tape /dev/rst*, /dev/nrst*, /dev/rmt/... floppy /dev/diskette, /dev/fd*, /dev/rdiskette, /dev/rfd* removable disk /dev/sr*, /dev/nsr*, /dev/dsk/c0t?d0s?, /dev/rdsk/c0t?d0s? frame buffer /dev/fb All entries set the device-minimum and device-maximum fields to the hex representations of ADMIN_LOW and ADMIN_HIGH, respectively. The device-authorization field is set to solaris.device.allocate, except for the framebuffer entry, where it is set to *. The device-name, device-type and device-clean fields are set to the following values: device-name device-type device-clean audio audio audio audio_clean_wrapper tape mag_tape_0,1,... st st_clean floppy floppy_0,1,... fd disk_clean removable disk cdrom_0,1,... sr disk_clean frame buffer framebuffer fb /bin/true ATTRIBUTES

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/* See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ deallocate(1), list_devices(1), bsmconv(1M), dminfo(1M), mkdevalloc(1M), mkdevmaps(1M), device_allocate(4), device_maps(4), attributes(5) 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. /etc/security/dev, mkdevalloc(1M), and mkdevmaps(1M) might not be supported in a future release of the Solaris Operating Environment. 28 Mar 2005 allocate(1)
