[Bridge] recent 2.6 kernels hang on bridge shutdown
With recent 2.6 kernels, the command
brctl delbr br0
hangs during shutdown, and the kernel prints this message again and again:
unregister_netdevice: waiting for br0 to become free. Usage count = 1
I was able to reproduce this problem with several kernels between
(and including) 2.6.9-rc1 and 2.6.11-rc2-bk9.
I haven't tried later versions...

[Bridge] Problem of lock when deleting a bridge
When i want to delete my test bridge, using:
ifconfig eth0 down
ifconfig eth1 down
ifconfig br0 down
brctl delif br0 eth0
brctl delif br0 eth1
brctl delbr br0
i get this error message from the kernel on the console:
unregister_netdevice: waiting for br0 to become free. Usage count =3D 2
The brctl user-level command is blocked.
Could you explain me what could likely be the cause of this error?
Thanks in advance,
#Louis.

[Bridge] brctl returns 0 on error
Hi,
"brctl" returns 0 when trying to delete non-existent bridge. If it
returns 0, scripting will be an headache. It should return different than 0.
# brctl delbr geek
bridge geek doesn't exist; can't delete it
# echo $?
0
Thanks.

[Bridge] Problem with bridge/8139too module under 2.4.27?
...ed this through the startup/shutdown scripts, and
have determine that the problem exists in the following sequence of
commands:
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
ifconfig eth0 up
ifconfig eth1 up
ifconfig eth0 down
ifconfig eth1 down
brctl delif eth0
brctl delif eth1
brctl delbr br0 <------ This is where the problem occurs
The machine running the kernel is a brouter with 4 NICs all running under
the 8139too driver - eth0 and eth1 form a bridge while eth2 and eth3 are
connected to different internal networks. I'm guessing that this is either a
problem with the bri...

1 host, 1 nick, 1 regular bridge, 1 local bridge, 5 vm
So Working on CEntOS 5 I am trying to sett up Xen with 2 bridges, one that
connects dom0 and most of the domU to the physical card and the out to the
network. Got that figured out no problem, now i want to have a second
bridge that runs a local network for all the doms that doesn''t connect to
the network.
With code I have found used in multiple places I can easily get 2 bridges,

Ubuntu 8.04 Hardy Heron bridged networking xen connectivity loss
...me what was wrong.
Well I think this issue is just the same. The moment I used apt to
install the Xen kernal and tools I lost internet connectivity. I have
been managing because I can restore connectivity be deleting the bridge
mpower@dodtsair:~$ sudo ifdown eth0
mpower@dodtsair:~$ sudo brctl delbr eth0
But that means any domUs will not have connectivity. I have not had any
till now so it wasn''t much of an issues. But thanks to your help now I
have XP running.
Ultimately I would really like you to show me the documentation that
tells me how to fix this. I am pretty sure it e...

Everything is back to normal. I cannot figure out what am I missing here?
Interfaces and routing look to be setup correctly. Is there something else I
need to be looking at?

[Bridge] Getting dynamic ip address for a bridge
Hello,
I how an embedded processor that needs to act as a bridge between a wireless
and wired network. I have managed to bring up the bridge fine. I can also
bring up the bridge with a static ip address. However I can not figure out
how to bring up the bridge with a dynamic ip address.
Is it possible to for a bridge to get a dynamically assigned ip address?

[Bridge] Bringing up bridge at boot (properly)
Currently my ethernet bridge has 2 intel 100mps NIC's that are

In addition to this I would like to access the internet from within the

gateway setup and no default route (0.0.0.0). I know this data has
