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

I have a new Polycom Spectralink 8002 and am having trouble with the configuration or the unit but I can't see what's wrong. The unit does not seem to even attempt to register with the Asterisk proxy but I can make calls to it. I have viewed the syslog from the device which it will actually write to the asterisk server so I know it can be reached. I have also run a sip debug and

This is a revised version of Kishore's patch to set message age appropriately in STP configuration packets.

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.

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] =

Merge the ioctl stub calls that just end up calling the sub-function to do the actual ioctl.

Running CentOS 5.4 x64. Have successfully bridged eth2 with br2 by following the instructions here: http://wiki.libvirt.org/page/Networking (under the RHEL section) Have been running several KVM VMs successfully via this bridge. I am now trying to bridge additional interfaces by using the same routine. Each bridge is named to correspond with the ethX device its bridged with. Example of

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.

Morning Everyone, I'm busy doing a rebuild of my home server and am tossing between VMware and KVM for this build. I already have experience with ESX, we use it at work, but I'm debating trying out KVM for a while. The server itself is a budget build using a Supermicro X8SAX board w/ i7-950 & 12GB RAM, LSI 3081 SAS RAID (1068e based), rolled into a NorcoTek 16 Bay SAS case. Not fancy

Hi, Since 1 month, I tried without any success to configure Samba. My problem is that winbind crashes when I list users and groups. And I think that it is linked to my trusted domains (wbinfo -domain=myADdomain -u works well).

http://developer.osdl.org/shemminger/patches/2.6.12-rc4-bridge/ Here are some patches for requested features, given basic testing but need more testing before they are publicly ready: bridge-csum - turn on bridge pseudo-device flags so that smart hardware does less work. Helps Xen bridge-flush - add /sys/class/net/brX/bridge/flush write only hook to flush

Hi, all, I wish to copy over fdb(forwarding database entries) learnt over from one interface onto as they are from another interface. Like for eg : brctl showmacs br0 port no mac addr is local? ageing timer 1 00:30:1a:01:6f:e4 no 0.46 1 00:30:1a:1c:3d:b7 yes 0.00 2 00:30:1a:1c:3d:b8 yes

Hi all, I try to reduce the time of link break detection for the STP. I want to make a timer who detect a link failure within a few times instead of waiting max age timeout. The problem is that my timer isn't take in account by the bride and i really don't know why, can someone help me ? Here's what I've done : in file br_stp_timer.c : /* called under bridge lock */ static

I've added the options --min-age=SECONDS and --max-age=SECONDS to allow rsync to skip files based on how recently they were modified. Setting --min-age=30 (for example) would cause rsync to skip files that had been modified within the last 30 seconds. Setting --max-age=7776000 would cause rsync to skip files that had been modified more than 90 days ago (7776000 == 60*60*24*90). I realize
