2013-02-13bridge: Separate egress policy bitmapVlad Yasevich
Add an ability to configure a separate "untagged" egress policy to the VLAN information of the bridge. This superseeds PVID policy and makes PVID ingress-only. The policy is configured with a new flag and is represented as a port bitmap per vlan. Egress frames with a VLAN id in "untagged" policy bitmap would egress the port without VLAN header.

2013-02-13bridge: Add vlan support for local fdb entriesVlad Yasevich
When VLAN is added to the port, a local fdb entry for that port (the entry with the mac address of the port) is added for that VLAN. This way we can correctly determine if the traffic is for the bridge itself. If the address of the port changes, we try to change all the local fdb entries we have for that port.

2013-02-13bridge: Add vlan support to static neighborsVlad Yasevich
When a user adds bridge neighbors, allow him to specify VLAN id. If the VLAN id is not specified, the neighbor will be added for VLANs currently in the ports filter list. If no VLANs are configured on the port, we use vlan 0 and only add 1 entry.

2013-02-13bridge: Add vlan to unicast fdb entriesVlad Yasevich
This patch adds vlan to unicast fdb entries that are created for learned addresses (not the manually configured ones).

2013-02-13bridge: Add the ability to configure pvidVlad Yasevich

2013-02-13bridge: Implement vlan ingress/egress policy with PVID.Vlad Yasevich
At ingress, any untagged traffic is assigned to the PVID. Any tagged traffic is filtered according to membership bitmap. At egress, if the vlan matches the PVID, the frame is sent untagged.

2013-02-13bridge: Add netlink interface to configure vlans on bridge portsVlad Yasevich

2013-02-13bridge: Add vlan filtering infrastructureVlad Yasevich
Adds an optional infrustructure component to bridge that would allow native vlan filtering in the bridge. Each bridge port (as well as the bridge device) now get a VLAN bitmap. Each bit in the bitmap is associated with a vlan id. This way if the bit corresponding to the vid is set in the bitmap that the packet with vid is allowed to enter and exit the port. Write access the bitmap is protected by RTNL and read access protected by RCU. Vlan functionality is disabled by default. Signed-off-by: Vlad Yasevich <vyasevic@redhat.com> Signed-off-by: David S.

2013-02-11netpoll: Fix __netpoll_rcu_free so that it can hold the rtnl lockNeil Horman
__netpoll_rcu_free is used to free netpoll structures when the rtnl_lock is already held. The mechanism is used to asynchronously call __netpoll_cleanup outside of the holding of the rtnl_lock, so as to avoid deadlock. Unfortunately, __netpoll_cleanup modifies pointers (dev->np), which means the rtnl_lock must be held while calling it. Further, it cannot be held, because rcu callbacks may be issued in softirq contexts, which cannot sleep. Fix this by converting the rcu callback to a work queue that is guaranteed to get scheduled in process context, so that we can hold the rtnl properly while calling __netpoll_cleanup Tested successfully by myself.

Commit 63233159fd4e596568f5f168ecb0879b61631d47: bridge: Do not unregister all PF_BRIDGE rtnl operations introduced a bug where a removal of a single bridge from a multi-bridge system would remove MDB netlink handlers. The handlers should only be removed once all bridges are gone, but since we don't keep track of the number of bridge interfaces, it's simpler to do it when the bridge module is unloaded.

In case of rehashing, introduce a global variable 'br_mdb_rehash_seq' which gets increased every time when rehashing, and assign net->dev_base_seq + br_mdb_rehash_seq to cb->seq. In theory cb->seq could be wrapped to zero, but this is not easy to fix, as net->dev_base_seq is not visible inside br_mdb_rehash(). In practice, this is rare.

2012-11-14bridge: add root port blockingstephen hemminger
This is Linux bridge implementation of root port guard. If BPDU is received from a leaf (edge) port, it should not be elected as root port. Why would you want to do this? If using STP on a bridge and the downstream bridges are not fully trusted; this prevents a hostile guest for rerouting traffic. Why not just use netfilter? Netfilter does not track of follow spanning tree decisions. It would be difficult and error prone to try and mirror STP resolution in netfilter module.

2012-11-14bridge: bridge port parameters over netlinkstephen hemminger
Expose bridge port parameter over netlink. By switching to a nested message, this can be used for other bridge parameters. This changes IFLA_PROTINFO attribute from one byte to a full nested set of attributes. This is safe for application interface because the old message used IFLA_PROTINFO and new one uses IFLA_PROTINFO | NLA_F_NESTED. The code adapts to old format requests, and therefore stays compatible with user mode RSTP daemon. Since the type field for nested and unnested attributes are different, and the old code in libnetlink doesn't do the mask, it is also safe to use with old versions of bridge monitor command. Note: although mode is only a boolean, treating it as a full byte since in the future someone will probably want to add more values (like macvlan has).
