similar to: [Bridge] RE: [VLAN] Re: [PATCH/RFC] Let {ip, arp}tables "see" bridged VLAN tagged{I,AR}P packets

Hi all, The patch below does four trivial changes and one big change Trivial changes, these are all in br_netfilter.c: - check ar_pln==4 when giving bridged ARP packets to arptables - delete unnecessary if in br_nf_local_in - add more logging for the "Argh" message - add some brag-comments in the file head comment Big change: let {ip,arp}tables see VLAN tagged {I,AR}P packets. This

This extension allows us to pass vlan ID and vlan protocol data to the host hypervisor as part of the vnet header and lets us take advantage of HW accelerated vlan tagging in the host. It requires support in the host to negotiate the feature. When the extension is enabled, the virtio device will enabled HW accelerated vlan features. Signed-off-by: Vladislav Yasevich <vyasevic at

Hi, The attached patches enables the bridge to filter and forward packets according to their IEEE 802.1q headers. The goals behind this change include : - Enable running STP on 802.1q tagged networks. STP packets must be untagged. It isn't obvious how else to enable STP with the current bridge and vlan code. - Add native support for an untagged vlan. Currently an untagged vlan can

This is the third version of the macvtap device driver, following another major restructuring and a lot of bug fixes: * Change macvtap to be based around a struct sock * macvtap: fix initialization * return 0 to netlink * don't use rcu for q->file and q->vlan pointers * macvtap: checkpatch.pl fixes * macvtap: fix tun IFF flags * Use a struct socket to make tx flow control work * disable

Hello, I have an issue with ebtables --arp-opcode and vlan support on the bridge. Ebtables support --arp-opcode witch is used for arp manipulation. ebtables -t nat -A PREROUTING -p arp --arp-opcode Request -j arpreply --arpreply-mac 10:11:12:13:14:15 --arpreply-target ACCEPT -i eth1 But it does not work when Ethernet frame comes tag with vlan pid. Can i overcome this limitation? Fanks

Changes since v9: * series re-ordering so make functionality more distinct. Basic vlan filtering is patches 1-4. Support for PVID/untagged vlans is patches 5 and 6. VLAN support for FDB/MDB is patches 7-11. Patch 12 is still additional egress policy. * Slight simplification to code that extracts the VID from skb. Since we now depend on the vlan module, at the time of input skb_tci is

This series of patches provides an ability to add VLANs to the bridge ports. This is similar to what can be found in most switches. The bridge port may have any number of VLANs added to it including vlan 0 priority tagged traffic. When vlans are added to the port, only traffic tagged with particular vlan will forwarded over this port. Additionally, vlan ids are added to FDB entries and become

A VLAN is basically a 4 byte "tag" that gets injected into the packet header when the packet enters the VLAN network. When we trunk a VLAN we say to the switch "pass packets on VLAN x but

Thank you everyone. OK, the mystery deepens, I guess. The machine does need to support several VLAN's, it is currently on a trunkport (8021q encapsulated), it made it into the ARP table - which I specifically tested for by physically unplugging the table, clearing the ARP table and plugging it back in. The ARP table currently looks like this: hq#show arp Protocol Address Age (min)

I compiled the latest 2.6.19 kernel and tested it with two 3COM 3c905c fast ethernet interfaces which work fine with vlan 802.1q tagging, but when I have added the eth0 and eth1

Hi to the ML. I''m new to VLAN configuration, and combining it to XEN is a bit difficult. I want to use VLAN because it''s possible to "arping" from a domU to an other, and VLAN looks like; the only solution to prevent that. May be I''m wrong if someone got a solution, I may be interrested. I''ve also tryed ebtables, but nothing to prevent arp

Hi, has anybody a running setup with 2 or more tinc daemons in switch mode which transport 8021q tagged traffic? I am trying to connect two segments with about 4 x 1000 mac addresses (distributed on different vlans). I am always running out of memory on one side. This happens only on the side where the arp requests come from. Currently there is no unicast traffic between the sides; only

Hi, I'm having trouble applying ebtables-brnf-3_vs_2.4.22.diff to 2.4.22-1.2166.nptl. Applying the patch did not go well. Can anyone help me with this? TIA.

This is based on an earlier patch from Eric Biederman adding forwarding between macvlans. I extended his approach to allow the administrator to choose the mode for each macvlan, and to implement a functional VEPA between macvlan. Still missing from this is support for communication between the lower device that the macvlans are based on. This would be extremely useful but as others have found out

I am using 8021q vlans on my servers, and I cannot figure out how to make PXE/DHCP work. Has anyone figured out how to do this ?
