ipv6 temporary address creation fails

It is now in the released 2.6.25-rc9, can you please consider a backport ?

Hi Tonfa,

I'll milestone this for 8.04.1 but the final decision to backport will be left to the kernel team. Otherwise this will be automatically available in the Intrepid Ibex 8.10 kernel. Thanks.

Hi tonfa,

Care to test the Intrepid Ibex 8.10 kernel which was most recently rebased with the upstream 2.6.25 kernel and also contains the patches you reference. It is currently available in the following PPA:

https://edge.launchpad.net/~kernel-ppa/+archive

If you are not familiar with how to install packages from a PPA basically do the following:

Create the file /etc/apt/sources.list.d/kernel-ppa.list to include the following two lines:

deb http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main
deb-src http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main

Then run the command:

sudo apt-get update

You should then be able to install the linux-image-2.6.25 kernel package. Please let us know your results. Thanks.

I couldn't test because my wireless card isn't activated:
# CONFIG_IWL3945 is not set

Moreover I have the same issue as when I was testing 2.6.25-rc from
kernel.org with gutsy, my screen is powered off when X starts unless I
remove splash from grub's command line (with Intel Corporation Mobile
945GM/GMS, 943/940GML Express Integrated Graphics Controller rev 3).

I should probably try to get some logs from via ssh and report a bug
since I can reproduce it with the kernel from intrepid.

Hi,

I've put up some kernel packages (linux-2.6.24-17.32ckingppa1 with a linux-image that contains the ipv6 fixes) in my PPA at https://launchpad.net/~colin-king/+archive

Please try this kernel and report any success/regressions. If this fixed the problem I can add the fix to Hardy 8.04.1. Thanks.

SRU Justification:

Impact: IPV6 temporary addresses won't work if two prefixes are
advertised on a link with one having a preferred_lifetime of 0 (usually
the case after a re-numbering).

The patch attached is from two relatively straight forward two upstream
cherry picks (originally davem/net-2.6.git and recently Linux
2.6.25-rc9) back ported to 2.6.24.

TEST CASE: See Bug Description

Patch http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=c7e5ae03ee0f8de37f9b55f441a6d7c546c997ea

It solves the ipv6 problem for me. No regression so far.

thanks

Accepted into -proposed, please test and give feedback here

I sadly can't test this easily anymore, since the renumbering is finished and the deprecated prefix isn't advertized anymore.
I can only confirm that the patch from the ppa was working (linux-2.6.24-17.32ckingppa4), as well as 2.6.25.

Copied to hardy-updates. The new kernel was tested extensively by many people, who reported back in other bug reports. Due to lack of feedback, this particular bug was not confirmed to be tested, though. Please report back here if the bug still occurs for you with the new kernel packages, then we will reopen this bug.

This is reported to be fixed in 2.6.25-rc9 and above, which would cover the 2.6.26 we currently have in intrepid; marking as fixed.
