net: ndo_fdb_dump should report -EMSGSIZE to rtnl_fdb_dump.

2016-02-26T20:04:02Z

When the send skbuff reaches the end, nlmsg_put and friends returns -EMSGSIZE but it is silently thrown away in ndo_fdb_dump. It is called within a for_each_netdev loop and the first fdb entry of a following netdev could fit in the remaining skbuff. This breaks the mechanism of cb->args[0] and idx to keep track of the entries that are already dumped, which results missing entries in bridge fdb show command.

switchdev: Require RTNL mutex to be held when sending FDB notifications

2016-01-29T00:21:31Z

When switchdev drivers process FDB notifications from the underlying device they resolve the netdev to which the entry points to and notify the bridge using the switchdev notifier. However, since the RTNL mutex is not held there is nothing preventing the netdev from disappearing in the middle, which will cause br_switchdev_event() to dereference a non-existing netdev. Make switchdev drivers hold the lock at the beginning of the notification processing session and release it once it ends, after notifying the bridge. Also, remove switchdev_mutex and fdb_lock, as they are no longer needed when RTNL mutex is held.

Define HW multicast entry: MAC and VID. Using a MAC address simplifies support for both IPV4 and IPv6. Signed-off-by: Elad Raz Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: Pass original device to port netdev driver

2015-12-15T16:58:20Z

switchdev drivers need to know the netdev on which the switchdev op was invoked. For example, the STP state of a VLAN interface configured on top of a port can change while being member in a bridge. In this case, the underlying driver should only change the STP state of that particular VLAN and not of all the VLANs configured on the port. However, current switchdev infrastructure only passes the port netdev down to the driver. Solve that by passing the original device down to the driver as part of the required switchdev object / attribute. This doesn't entail any change in current switchdev drivers. It simply enables those supporting stacked devices to know the originating device and act accordingly. Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

switchdev: respect SKIP_EOPNOTSUPP flag in case there is no recursion

2015-11-03T18:39:21Z

Caller passing down the SKIP_EOPNOTSUPP switchdev flag expects that -EOPNOTSUPP cannot be returned. But in case of direct op call without recurtion, this may happen. So fix this by checking it always on the end of __switchdev_port_attr_set function.

switchdev: fix: erasing too much of vlan obj when handling multiple vlan specs

2015-10-30T11:23:35Z

When adding vlans with multiple IFLA_BRIDGE_VLAN_INFO attrs set in AFSPEC, we would wipe the vlan obj struct after the first IFLA_BRIDGE_VLAN_INFO. Fix this by only clearing what's necessary on each IFLA_BRIDGE_VLAN_INFO iteration.
