net: bridge: Add support for offloading port attributes

2017-06-08T18:16:24+00:00

Currently the flood, learning and learning_sync port attributes are
offloaded by setting the SELF flag. Add support for offloading the
flood and learning attribute through the bridge code. In case of
setting an unsupported flag on a offloded port the operation will
fail.

The learning_sync attribute doesn't have any software representation
and cannot be offloaded through the bridge code.

net: bridge: fix a null pointer dereference in br_afspec

2017-06-06T20:05:31+00:00

We might call br_afspec() with p == NULL which is a valid use case if
the action is on the bridge device itself, but the bridge tunnel code
dereferences the p pointer without checking, so check if p is null
first.

bridge: Export VLAN filtering state

2017-05-26T19:18:44+00:00

It's useful for drivers supporting bridge offload to be able to query
the bridge's VLAN filtering state.

Currently, upon enslavement to a bridge master, the offloading driver
will only learn about the bridge's VLAN filtering state after the bridge
device was already linked with its slave.

Being able to query the bridge's VLAN filtering state allows such
drivers to forbid enslavement in case resource couldn't be allocated for
a VLAN-aware bridge and also choose the correct initialization routine
for the enslaved port, which is dependent on the bridge type.

bridge: netlink: check vlan_default_pvid range

2017-05-18T14:15:00+00:00

Currently it is allowed to set the default pvid of a bridge to a value
above VLAN_VID_MASK (0xfff). This patch adds a check to br_validate and
returns -EINVAL in case the pvid is out of bounds.

Reproduce by calling:

[root@test ~]# ip l a type bridge
[root@test ~]# ip l a type dummy
[root@test ~]# ip l s bridge0 type bridge vlan_filtering 1
[root@test ~]# ip l s bridge0 type bridge vlan_default_pvid 9999
[root@test ~]# ip l s dummy0 master bridge0
[root@test ~]# bridge vlan
port	vlan ids
bridge0	 9999 PVID Egress Untagged

dummy0	 9999 PVID Egress Untagged

bridge: netlink: account for IFLA_BRPORT_{B, M}CAST_FLOOD size and policy

2017-05-05T15:21:03+00:00

The attribute sizes for IFLA_BRPORT_MCAST_FLOOD and
IFLA_BRPORT_BCAST_FLOOD weren't accounted for in br_port_info_size()
when they were added. Do so now and also add the corresponding policy
entries:
