IPv6 Sparc64

IPv6 Sparc64

[Sten]

I have been trying to get ipv6 to work
on sparc64/kernel 2.4 but it looks like it
is broken somewhere in the kernel.
I was wondering if this was a known problem.


lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1

          RX bytes:8736 (8.5 Kb)  TX bytes:8736 (8.5 Kb)

[root@towel ip]# ping6 ::1
PING ::1(::1) from ::1 : 56 data bytes

It's the same on PARISC. However, on PARISC, although ping6 doesn't work,
telnet etc do work, as well as pinging the PARISC box from an Intel or
Alpha machine.

For now, i assume there might be an endianess issue in net/ipv6/raw.c
somewhere... Has anyone tested IPv6 on m68k?

Cheers,
Jochen

The reason I ask this is because I have been trying to setup a
tunnel, and I cant get it to work either with ifconfig or iproute.

[root@towel ip]# ip tunnel add blink mode sit remote x.x.x.x dev
eth0
ioctl: Invalid argument

At least on PARISC, this turned out to be an glibc issue. With the latest 
glibc from debian unstable, ping6 is now working OK:

# ping6 -n www.kame.net
PING www.kame.net(3ffe:501:4819:2000:203:47ff:fea5:3257) from

   The reason I ask this is because I have been trying to setup a
   tunnel, and I cant get it to work either with ifconfig or iproute.

The reason this fails is because SIOCADDTUNNEL uses SIOCDEVPRIVATE
which can't be translated properly to/from 32-bit apps running
on 64-bit kernels.
