2016-05-17switchdev: pass pointer to fib_info instead of copyJiri Pirko1-4/+2
The problem is that fib_info->nh is [0] so the struct fib_info allocation size depends on number of nexthops. If we just copy fib_info, we do not copy the nexthops info and driver accesses memory which is not ours. Given the fact that fib4 does not defer operations and therefore it does not need copy, just pass the pointer down to drivers as it was done before.

2016-04-24switchdev: Adding complete operation to deferred switchdev opsElad Raz1-0/+6
When using switchdev deferred operation (SWITCHDEV_F_DEFER), the operation is executed in different context and the application doesn't have any way to get the operation real status. Adding a completion callback fixes that. This patch adds fields to switchdev_attr and switchdev_obj "complete_priv" field which is used by the "complete" callback. Application can set a complete function which will be called once the operation executed.

2016-02-26net: ndo_fdb_dump should report -EMSGSIZE to rtnl_fdb_dump.MINOURA Makoto / 箕浦 真1-1/+4
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.

2016-01-29switchdev: Require RTNL mutex to be held when sending FDB notificationsIdo Schimmel1-7/+8
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.

2015-12-15switchdev: Pass original device to port netdev driverIdo Schimmel1-0/+12
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.

One more missing piece of the puzzle.

Before this patch, "bridge vlan show": $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlans 57 sw1p1 << device side vlans (missing) sw1p2 57 sw1p2 sw1p3 sw1p4 br0 None (When the port is bridged, the output repeats the vlan list for the vlans on the bridge side of the port and the vlans on the device side of the port. The listing above show no vlans for the device side even though they are installed). After this patch: $ bridge -c vlan show port vlan ids sw1p1 30-34 << bridge side vlan 57 sw1p1 30-34 << device side vlans 57 3840 PVID sw1p2 57 sw1p2 57 3840 PVID sw1p3 3842 PVID sw1p4 3843 PVID br0 None I re-used ndo_dflt_bridge_getlink to add vlan fill call-back func. switchdev support adds an obj dump for VLAN objects, using the same call-back scheme as FDB dump.
