Description Jeffrey Bisti 2003-10-07 18:16:00 UTC
The following has be reported by IBM LTC:  
IPV6 scope address incorrectly generated
Hardware Environment:

Software Environment:
31 and 64 bit rhel3 as vm guests

Steps to Reproduce:
1. insmod ipv6
2. ifconfig eth36

Actual Results:
eth36     Link encap:Ethernet  HWaddr 00:02:55:09:E7:D9
          inet addr:  Bcast:  Mask:
  ---->   inet6 addr: fe80::202:55ff:fe09:e7d9/64 Scope:Link
          RX packets:3417 errors:0 dropped:0 overruns:0 frame:0
          TX packets:264 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          RX bytes:356200 (347.8 Kb)  TX bytes:26599 (25.9 Kb)

Expected Results:
      something like:           vv vv 
          inet6 addr: fe80::2:5500:2109:e7d9/64 Scope:Link
          or                    vv vv 
          inet6 addr: fe80::2:5500:7a09:e7d9/64 Scope:Link                     

Additional Information:
 The unique identifier that gets passed from the osa isn't being incorporated
into the ipv6 address. The address should be something like fe80::2:55[unique
id]09:e7d9/64. Also, it looks like the mac address isn't being read into the
address correctly (fe80::202:55... being generated instead of fe80::2:55...). 

IPv6 addresses that are configured onto the interface do not seem to take
effect. I cannot reach the system on any IPv6 addresses, configured or
autoconfigured, while I am able to communicate over IPv6 interfaces on non-rhel

Comment 1 Phil Knirsch 2003-10-17 08:44:26 UTC
Is this by chance a qeth interface? If so, then it most likely doesn't work
because we had to disable the IPV6 feature in the qeth driver as the driver used
kernel_symbols which were not exported.

Read ya, Phil

Comment 2 Jeffrey Bisti 2003-10-17 14:20:48 UTC
Yes it is a qdio interface.

Comment 4 Phil Knirsch 2004-04-22 13:35:53 UTC
Have you given the latest kernel a try? It has updated qeth drivers
which might contain a fix for the problem you reported.

Read ya, Phil

Comment 5 Bob Johnson 2004-08-11 19:45:50 UTC
Need info, IBM can you test ?

Comment 6 Bob Johnson 2004-08-23 01:13:06 UTC
Been in IBM's court since 4/22. Bill, Ingolf, can you provide some
assitance here ?

Comment 7 Helen Fischer 2004-08-23 13:53:03 UTC
I tried this again on and received the same results:

kernel level:  2.4.21-18.EL

Results of ifconfig:
eth1      Link encap:Ethernet  HWaddr 00:04:AC:7C:AA:CA
          inet addr:  Bcast:   
          inet6 addr: fe80::204:acff:fe7c:aaca/64 Scope:Link
          RX packets:1520 errors:0 dropped:0 overruns:0 frame:0
          TX packets:11 errors:0 dropped:0 overruns:0 carrier:0

----- Additional Comments From fischerh@us.ibm.com  2004-09-26 20:14 EDT -------
I tried this on RHEL4 - beta 1.  The IPV6 link address is not generated 
correctly .  In addition, we are unable to run IPV6 traffic over qeth devices. 
Kernel level is 2.6.8-1.528.2.5.  

eth0      Link encap:Ethernet  HWaddr 00:09:6B:1A:00:C7
          inet addr:  Bcast:  Mask:
          inet6 addr: fe80::209:6bff:fe1a:c7/64 Scope:Link 

Comment 9 Oliver Paukstadt 2004-10-26 15:58:29 UTC
Same problem here.
We are not able to run ipv6 over vswitch.
q lan detail shows no ipv6 addresses registered with that guest.
ipv4 adresses are shown (and work) and ipv6 works if we use other
enterprise distributions.
kernel is 2.4.21-20.EL.

Comment 10 Pete Zaitcev 2005-05-13 17:56:49 UTC
As far as I know, IPv6 is not supported on qeth in RHEL 3.
Even if we manage to get addresses generated right, it won't
exchange packets correctly. Jan, do you have a comment?

Please do not mix the RHEL 4 into this bug.

Comment 11 RHEL Product and Program Management 2007-10-19 19:34:17 UTC
