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 part of the lookup. This way we correctly identify the FDB
A single vlan may also be designated as untagged. Any untagged traffic
recieved by the port will be assigned to this vlan. Any traffic exiting
the port with a VID matching the untagged vlan will exit untagged (the
bridge will strip the vlan header). This is similar to "Native Vlan" support
available in most switches.
The default behavior ofthe bridge is unchanged if no vlans have been
Changes since rfc v2:
- Per-port vlan bitmap is gone and is replaced with a vlan list.
- Added bridge vlan list, which is referenced by each port. Entries in
the birdge vlan list have port bitmap that shows which port are parts
of which vlan.
- Netlink API changes.
- Dropped sysfs support for now. If people think this is really usefull,
can add it back.
- Support for native/untagged vlans.
Changes since rfc v1:
- Comments addressed regarding formatting and RCU usage
- iocts have been removed and changed over the netlink interface.
- Added support of user added ndb entries.
- changed sysfs interface to export a bitmap. Also added a write interface.
I am not sure how much I like it, but it made my testing easier/faster. I
might change the write interface to take text instead of binary.
Vlad Yasevich (11):
bridge: Add vlan filtering infrastructure
bridge: Validate that vlan is permitted on ingress
bridge: Verify that a vlan is allowed to egress on give port
bridge: Cache vlan in the cb for faster egress lookup.
bridge: Add vlan to unicast fdb entries
bridge: Add vlan id to multicast groups
bridge: Add netlink interface to configure vlans on bridge ports
bridge: Add vlan support to static neighbors
bridge: Add the ability to configure untagged vlans
bridge: Implement untagged vlan handling
bridge: Dump vlan information from a bridge port
