[Bridge] 2.6.11/10 (and probably others), usbnet + bridge => massive memory corruption

[Bridge] 2.6.11/10 (and probably others), usbnet + bridge => massive memory corruption

[Adam M]

Hi all,

Well, I've been trying to set up Debian on an OpenZaurus bootstrap..
well, there were some complications after I enabled bridging between
usbnet and via_rhine ethernet,

My set up includes,

1. Network interface setup using usbnet
2. Bridge eth0+usb0=>main (bridge name)
3. bootstrap Debian on an NFS volume.

There are no lost pockets or any type of kernel oops. I can produce a
segfault in the brctl utility by trying to turn off STP when there are
interfaces attached, but that's about it.

Almost immediately after I set up the bridge, I've started to
experience application dumping core. Things like firefox stopped
working, but thunderbird was ok. Or xterm segfaulting... During this
time the network (bridge) seemed ok.

After a short while, everything seems to just crap out either by
kernel rebooting or stalling (no kernel oops).

So far I'm been generating a lot of traffic over usbnet (no bridge) and
things seem to work OK... After I enable bridging, well, scary things happen.

PS. I'm not on this list, so please CC me in all replies. Thanks!

Hi Adam, 

like you can see in the bridge Mailing list, I had the same problem.
But then I added some networking features in my kernel Konfiguration
(xconfig) and everything works fine.
Here are my changes:

Networking support->Networking options->	Packet socket =Y
							TCP/IP networking= Y
								IP
multicasting= Y
								IP advanced
router= Y
And I suppose the most importang change was:

Networking support->Networking packet filtering->	Network packet
filtering replaces ipchains =Y
	
Bridged IP/ARP packets filtering=Y	
									

Regards
Sascha
