Description Simon Farnsworth 2008-03-18 13:09:20 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-GB; rv:1.8.1.12) Gecko/20080208 Fedora/2.0.0.12-1.fc8 Firefox/2.0.0.12

Description of problem:
We have a system with a Jetway J7F5M2G motherboard, using a VIA Velocity gigabit ethernet chip. When it boots, it ignores all multicast traffic; we can get it to listen for multicast traffic by switching allmulti or promisc on, then off again:

ifconfig eth0 allmulti ; ifconfig eth0 -allmulti
or
ifconfig eth0 promisc ; ifconfig eth0 -promisc

I can run any tests you like on the box.

Version-Release number of selected component (if applicable):

How reproducible:
Always


Steps to Reproduce:
Install Fedora on a box with a VIA Velocity ethernet chip. Boot on a network with multicast traffic; see the box ignore the multicast traffic completely.

Comment 1 Simon Farnsworth 2008-03-18 13:12:05 UTC
Further to the report; once we've set allmulti or promisc mode, the chip stops
filtering multicast traffic, even though we've disabled promisc or allmulti.

Comment 2 David Woodhouse 2008-06-04 16:06:23 UTC
<dwmw2> rebuild driver with some printks in velocity_set_multi() to see what
it's doing (and if it's actually being called at the right times)
<farnz> dwmw2: Did that at the time - it's apparently setting the right stuff,
but the chip ignores it.

Do we have access to VIA docs? If not, maybe we should put it into allmulti mode
at all times if the multicast filtering isn't working.

Comment 3 Bug Zapper 2008-11-26 10:12:36 UTC
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8.  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bug reports from releases that are no longer maintained.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 '8'.

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 8'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 8 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: 
http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Comment 4 Bug Zapper 2009-01-09 06:13:00 UTC
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 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.
