net: convert bridge_nf to use skb extension infrastructure

2018-12-19T19:21:37+00:00

This converts the bridge netfilter (calling iptables hooks from bridge)
facility to use the extension infrastructure.

The bridge_nf specific hooks in skb clone and free paths are removed, they
have been replaced by the skb_ext hooks that do the same as the bridge nf
allocations hooks did.

netfilter: avoid using skb->nf_bridge directly

2018-12-19T19:21:37+00:00

This pointer is going to be removed soon, so use the existing helpers in
more places to avoid noise when the removal happens.

net: bridge: Handle NETDEV_PRE_CHANGEADDR from ports

2018-12-14T02:41:38+00:00

When a port device seeks approval of a potential new MAC address, make
sure that should the bridge device end up using this address, all
interested parties would agree with it.

net: bridge: Issue NETDEV_PRE_CHANGEADDR

2018-12-14T02:41:38+00:00

When a port is attached to a bridge, the address of the bridge in
question may change as well. Even if it would not change at this
point (because the current bridge address is lower), it might end up
changing later as a result of detach of another port, which can't be
vetoed.

Therefore issue NETDEV_PRE_CHANGEADDR regardless of whether the address
will be used at this point or not, and make sure all involved parties
would agree with the change.

net: switchdev: Add extack argument to switchdev_port_obj_add()

2018-12-13T00:34:21+00:00

After the previous patch, bridge driver has extack argument available to
pass to switchdev. Therefore extend switchdev_port_obj_add() with this
argument, updating all callers, and passing the argument through to
switchdev_port_obj_notify().

net: bridge: Propagate extack to switchdev

2018-12-13T00:34:21+00:00

ndo_bridge_setlink has been updated in the previous patch to have extack
available, and changelink RTNL op has had this argument since the time
extack was added. Propagate both through the bridge driver to eventually
reach br_switchdev_port_vlan_add(), where it will be used by subsequent
patches.

net: ndo_bridge_setlink: Add extack

2018-12-13T00:34:21+00:00

Drivers may not be able to implement a VLAN addition or reconfiguration.
In those cases it's desirable to explain to the user that it was
rejected (and why).

To that end, add extack argument to ndo_bridge_setlink. Adapt all users
to that change.

Following patches will use the new argument in the bridge driver.

bridge: Add br_fdb_clear_offload()

2018-12-07T20:59:08+00:00

When a driver unoffloads all FDB entries en bloc, it's inefficient to
send the switchdev notification one by one. Add a helper that unsets the
offload flag on FDB entries on a given bridge port and VLAN.
