HP-UX 11i v1.6 critical impact:

IPv6 interface name and index mapping APIs - now available (CrUn138)

Problem description

The identified Application Programming Interfaces (APIs), as defined in RFC 2553, Basic Socket Interface Extensions for IPv6, exist on Tru64 UNIX and are now available with HP-UX 11i v2 update 2.

IPv6 is the next generation of the Internet Protocol. These APIs perform conversions between interface indexes and interface names as follows:

• if_nametoindex maps an interface name to an interface index.

• if_indextoname maps an interface index to an interface name.

• if_nameindex returns an array of all interface names and indexes.

• if_freenameindex frees dynamic memory allocated to the array of interface names and indexes.

Identifiers

if_freenameindex	if_nameindex
if_indextoname	if_nametoindex

Solution description

Review your code and the applicable manpages for more information on interface mapping APIs and their use.

These APIs are contained in a software depot for current HP-UX versions that run on the PA-RISC platform, and are available with HP-UX 11i v2 update 2.
