Bug 496739

I can reproduce this. It happens *most* of the times, when a interface goes down/up which radvd is configured for. (even for wlan or tap devices)

$ rpm-qa| grep radvd

radvd-1.1-6.fc10.x86_64

best regards

Still an issue on F11 with: radvd-1.1-8.fc11.x86_64

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '10'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 10's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 10 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Hi,
I'm not able to reproduce it. I'm just trying it on F-11 ravdv-1.1.9 (nothing important between 8 & 9). Everything runs right.

What about your kernel version? Any custom compilation of kernel, options, ...? Could you send me your radvd.conf?

Thanks Jiri

nothing special here, except a custom build madwifi module.

Everytime when i restart my hostapd, radvd will get ~95% CPU after a few seconds. Unplugging and replug the ethernet (or powercircle the switch) has the same result.

Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

I was not able to reproduce but I've found out the upstream version 1.5 contains fix for it. Radvd was updated to radvd-1.5. Could you test it?

I forgot to alert moving this bug to F-12. F12 + rawhide are re-based.

Please, could you test version for F12 from testing repository. I'm willing to re-base F11 too but I prefer to test it firstly.

Thanks

Jiri

Some news? There is radvd-1.6 in testing repository ...

Sorry for the late reply. I'm horrible busy these days. :-(

I have another new box running "F12" and "radvd-1.5-2.fc12.x86_64". On this box, it seems there is no problem when a interface is coming up again, when it is gone away once.

Currently i can't update our main machine (which has *a lot* more interfaces), and it is still F10 which runs "radvd-1.1-6.fc10.x86_64" and the error still exist, of course. I'm trying to upgrade this box to F12 as soon as possible.

Indeed, 24-hours are not enough ;-)

best regards

I just realized, that i can simply get radvd from F12 and update via rpm, even on F10. Doh :-)

And the error seems to be history now.

Now running "radvd-1.5-2.fc12.x86_64" on F10. I did a quick test restarting radvd, and than taking the port on the switch down/up remotely. Works fine.

best regards

Thanks a lot for your test & report. Well, I'm going to close this bug.

Just before closing one remark - there were messaged bug #579869 that is fixed by radvd-1.6. This update is in testing repository. I recommend to use this newer update.
