Description hartzell 2000-06-08 21:00:01 UTC 
Release 3.0 of the ATM HARP software does not support IPv6.

HARP's 'ATM' command core dumps when you try to pack an IPv6 address
into the IPv4 command line option.  There are also problems with
IPv4 and the ILMI daemon, etc.

The developers of HARP (bless them) are no longer funded by DARPA to 
continue work on the HARP platform, so it is unlikely that HARP will
be maintained or fixed by them.

Many organizations now testing or using IPv6 over WANs need ATM PVC
support, since ATM is used on the WAN side for virtual links.

At least, it would be nice to have the IPv6 ATM PVC support.  There is
probably not that much call for IPv6 ILMI, CLIP, support, etc.

Fix: 

change the kernel code (if needed) and the userland binaries code for HARP?
How-To-Repeat: Attempt to execute a:

 atm add pvc hfa0 0 300 aal5 llc/snap ip ni1 4FFE:1800:1FE:2::2

to tell the kernel that the IPv6 host 4FFE:1800:1FE:2::2 is on the
far end of ATM PVC 0,300.

This results in a Segmentation Fault, with an 'atm.core' file dump.

HARP has never claimed IPv6 support.
