[Bridge] Bridge port states
Hi all,
Can anyone explain me why we need all this per port state information. A
bridge port seems to be either in BR_STATE_LISTENING, BR_STATE_LEARNING
or BR_STATE_FORWARDING. I don't get it, thought the bridge is learning
from MAC addresses of the received packets, therefore while listening.
Why a bridge port distinquishes these states?
Thanx,
Patrick

[Bridge] Bridging with STP seems to learn mac-address on wrong ports
...rnel 2.6.11.12 and 2.6.13.2, and both exhibit
this problem.
The following fix solved it for me on 2.6.11.12:
In net/bridge/br_stp_bpdu.c, in function br_stp_handle_bpdu i changed
br_fdb_insert(p->br, p, eth_hdr(skb)->h_source,0);
to
if (!br->stp_enabled || p->state == BR_STATE_LEARNING
|| p->state == BR_STATE_FORWARDING)
br_fdb_insert(p->br, p, eth_hdr(skb)->h_source, 0);

[Bridge] bridge problem when one interface is in blocking mode
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
