Description Andrew Sydelko 2001-02-23 14:18:04 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; SunOS 5.8 sun4u)

The way IPv6 was compiled as a module does not
allow for the "current" way of numbering.

Reproducible: Always
Steps to Reproduce:
1. modprobe ipv6
2.look for "IPv6 addrconf: prefix with wrong length 64" in kernel messages

Expected Results:  the EUI-64 is the standard (or the way that Solaris and
FreeBSD do it)
way of doing IPv6.

The kernel config (in menuconfig) should have:

<M>   The IPv6 protocol (EXPERIMENTAL) (NEW)  
          [*]     IPv6: enable EUI-64 token format (NEW)     
          [*]       IPv6: disable provider based addresses (NEW)

Bieringer's Linux IPv6 web page:

What kernel are you looking at ? We changed to this options to what
you propose some time ago.

Comment 2 Andrew Sydelko 2001-02-23 16:26:43 UTC
It's the default kernel for wolverine.
I looked in /usr/src/linux-2.4.1/configs/*
for the kernel config and the ones that have IPv6
enabled have the following set:

kernel-2.4.1-i386.config:# CONFIG_IPV6_EUI64 is not set

[root@localhost sysconfig]# uname -a
Linux localhost.localdomain 2.4.1-0.1.9 #1 Wed Feb 14 22:15:15 EST 2001 i686 

[root@localhost sysconfig]# rpm -q kernel

[root@localhost sysconfig]# cat /etc/redhat-release 
Red Hat Linux release 7.0.91 (Wolverine)

Comment 3 Michael K. Johnson 2001-02-23 16:28:24 UTC
Correct, not in wolverine.  Will be in all builds 2.4.1-0.1.14 or later.
