This patch fixes a Solaris specific issue with buffer overrun of
if_nameindex->if_name. Memory for this buffer is allocated by
if_nameindex() and therefore correct string routines must be used
to access it. The patch has been submitted to the community
but has not been accepted yet.

The details can be found in the following location
