HP DLPI Features

Fine-grained Privileges with Security Containment Release

When Security Containment product version B.11.23.01 or later is installed, HP DLPI is aware of the individual privileges that are relevant for operations on networking links, namely:

When the security containment product is installed, HP DLPI checks for the above privileges, instead of checking for root user. With the security containment release, the root user will have all the 3 privileges, mentioned above. However non-root users must be granted these privileges as appropriate, when running HP DLPI applications that perform privileged operations.

	NOTE: If the required privileges are not granted to these HP DLPI applications, the APIs may return DL_SYSERR with EPERM Unix error number.

For more information on the fine grained privileges, see HP-UX 11i Security Containment Administrator’s Guide.

	NOTE: The HP ATM adapter provides its own “native” DLPI provider, which should not be confused with this DLPI provider.

Currently, HP DLPI does not include:

Device File Format

The description of the device file formats required for accessing the STREAMS DLPI LAN driver is as follows:

	NOTE: HP DLPI supports up to 100 non-clone device files. HP recommends that device file names follow the naming convention /dev/dlpiX, where X is the number of the device.

Header Files

There are two DLPI header files: dlpi.h and dlpi_ext.h. Both these header files are present in /usr/include/sys.

dlpi.h contains definitions for the standard DLPI primitives, and dlpi_ext.h contains definitions for the HP extended DLPI primitives.
