Merge the ioctl stub calls that just end up calling the sub-function to do the actual ioctl. Move br_get_XXX_ifindices into the ioctl file as well where they can be static. diff -Nru a/net/bridge/br_device.c b/net/bridge/br_device.c --- a/net/bridge/br_device.c 2004-05-20 10:51:05 -07:00 +++ b/net/bridge/br_device.c 2004-05-20 10:51:05 -07:00 @@ -19,21 +19,6 @@ #include <asm/uaccess.h>

Hi, I'm trying to modify the stp kernel files in order to implements the RSTP. I've already modify the bpdu format like this : ------------------------------------------------------------------------------------------------------------------------------------ typedef struct { int topo_change = 0; int proposal = 0; int port_role[2] = {0,0} ; //role du port ?metteur du BPDU

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.

A malicious actor behind one bridge port may spam the kernel with packets with a random source MAC address, each of which will create an FDB entry, each of which is a dynamic allocation in the kernel. There are roughly 2^48 different MAC addresses, further limited by the rhashtable they are stored in to 2^31. Each entry is of the type struct net_bridge_fdb_entry, which is currently 128 bytes big.

I saw some big mistakes, here's the correct version : -------------------------------------------------------------------- void br_send_config_bpdu(struct net_bridge_port *p, struct bpdu *bpdu) { unsigned char buf[42]; buf[0] = bpdu->bpdu_header.protocol[0]; //0x00 buf[1] = bpdu->bpdu_header.protocol[1]; //0x00 buf[2] = bpdu->bpdu_header.version; //0x02 buf[3] =

Fixes message_age field update in config BPDUs. Also checks whether the BPDU message age has exceeded bridge max age before transmitting config BPDUs.

Hello! "brctl stp br0" would crash brctl provided that br0 is a bridge. This is caused by incorrect number of arguments in the commands table. "stp" needs at least 2 arguments after "stp".

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 -

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.

In particular, I've a physical interface (eth2) connected to a Cisco trunk port (so, the traffic to/from eth2 is tagged). I've added eth2 to a bridge ('brctl addif somebrige

Hello all, First thanks to all for helping me. I have an issue to bring up bridging isis packets using BRCTL. As i am quite a newbie, maybe this is not possible or maybe I forget to load modules so that the bridging I am trying to put in place work properly. Here is the configuration I used: I1 ------ eth1 (physical interface of my linux machine) ----------- BRIDGE ----------- n1-eth0 (tuntap

Hello, I am wondering if any of you knows how to add BR2684-rt nas interfaces into a Ethernet bridge, I know that brctl will work with BR2684-br, but not for BR2684-rt. Many thanks!
