Here is the proposed revision to the bridge utilities interface to the kernel. The driving force is that the existing interface can't easily be converted to 32/64 bit compat. Right now, the bridge-utils (brctl) tries to handle 32bit command on 64 bit kernel, but the code is limited to sparc and wrong. Here is what I am thinking. get version - not needed? get bridges -

Hi, Is there any particular reason why the same physical port cannot be added to multiple bridges? Is it because of STP? If I am not using STP - can I change the code to have the same physical port in 2 VLANs? Is that a safe change? Thanks, Abhijit

I am battling an issue with use of bridging with xen. For some yet undetermined reason supposedly relating to stp, they assign a mac address of fe:ff:ff:ff:ff:ff to the bridge. Was hoping someone here may be able to elaborate on that. If I enslave a bridge to an ethernet, and than restart that network interface, should the bridge operation behave the same after the ip interface is restarted?

This is the 2.4 version which incorporates the observations from Kishore about 2.6. The existing 2.4 code set the age properly, but did not increment correctly for HZ=1000 and could send a stale (expired) configuration.

Hi there, I am a student and working on a project where i need to configure RSTP (802.1w) on SUSE 10 kernel 2.6 so that i can able to analyse efficient link fail-over time, i have found STP configuration at ( http://linux-net.osdl.org/index.php/Bridge ) but coulnt find partticular RSTP configuration. i would appriciate if you could help me in this regard. cheers, was

Hello all, I would like to know if it is possible to have 2 bridge instances running - one for the internal network and the other for the external network. What I need to explain is that I need the internal bridge to go though the Linux Kernel and pass its packets to the external network bridge. I am also hopeful that the internal network bridge will not need an IP address as I am hoping to

Hi all, Can someone tell me where to find source code for RSTP for linux 2.6 kernel? Thank you in advance. -Marc.

Bridge locking for /sys/class/net/br0/bridge/stp_enabled was wrong. Another bug in bridge utilities makes it such that this interface, meant it wasn't being used. The locking needs to be removed from set_stp_state(), the lock is already acquired down in br_stp_start()/br_stp_stop.

Hello, I am a student considering participating in Google Summer of Code program. I came across Stephen Hemminger's idea of implementing a RSTP posted on http://developer.osdl.org/dev/soc/ and found it interesting. In attachment there's my proposal, which I just submitted to google. Please share your comments. -- tadeusz andrzej kad?ubowski -------------- next part --------------

Adding an STP state seems like a bad idea. Aren't br->stp_enabled and (dev->flags & IFF_UP) sufficient to determine whether check_link() should reenable a port? > -----Original Message----- > From: bridge-bounces@lists.osdl.org > [mailto:bridge-bounces@lists.osdl.org] On Behalf Of Mark Ruijter > Sent: Tuesday, July 20, 2004 7:25 AM > To: Stephen Hemminger > Cc:

Avoid poisoning of the bridge forwarding table by frames that have been dropped by filtering. This prevents spoofed source addresses on hostile side of bridge from causing packet leakage, a small but possible security risk.

Hi, We have a simple bridge setup but the ping (and other network traffic) does not work reliably. After tracing the code, it looks like a software bug. Since bridge software is been running by thousands of people. I guess I am wrong. Anyway, here is the problem. There are 2 boxes and each one has 2 interfaces, 1 ethernet and 1 wifi. STP is enabled for the bridge to avoid the loop. So the box 1

hi list! i'm trying to find a convenient way to build a redundant filtering bridge under linux i looked at carp project, but carp doesn't support bridge now i thing the most appropriate way is using stp or rstp it seems that 2.6 kernel supports stp but what about rstp? I read some docs about stp, but they are rather outdated (2001 and kernel 2.2) there are several problems indeed: *

The patch below updates MAINTAIER address Individuals (Only Andrew :): osdl.org -> linux-foundation.org Lists: osdl.org -> lists.osdl.org I assume the latter will change at some stage, but at least with this change the osdl/linux-foundation lists are consistent.

Sorry, if this question has been answered before, but I could not find out with a brief look. How can I set the MAC address for a bridge? The MAC address given for the bridge device seems to be the one it sends network packets with if the bridge device has an IP address set. Apparently the bridge starts with a zero MAC address and when the first interface is attached to it, it takes its MAC
