* net: switchdev: Remove bridge bypass support from switchdevArkadi Sharshevsky2017-08-071-435/+0
| | | | | | | | | | | | | | | | | | | | Currently the bridge port flags, vlans, FDBs and MDBs can be offloaded through the bridge code, making the switchdev's SELF bridge bypass implementation to be redundant. This implies several changes: - No need for dump infra in switchdev, DSA's special case is handled privately. - Remove obj_dump from switchdev_ops. - FDBs are removed from obj_add/del routines, due to the fact that they are offloaded through the bridge notification chain. - The switchdev_port_bridge_xx() and switchdev_port_fdb_xx() functions can be removed.

While we can ignore calls being made to non-bridge ports inside the driver, a better fix would be to push this check up to the switchdev layer. Note that these ndos can be called for non-bridged netdev, but this only happens in certain PF drivers which don't call the corresponding switchdev functions anyway.

* rtnetlink: fdb dump: optimize by saving last interface markersRoopa Prabhu2016-09-011-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fdb dumps spanning multiple skb's currently restart from the first interface again for every skb. This results in unnecessary iterations on the already visited interfaces and their fdb entries. In large scale setups, we have seen this to slow down fdb dumps considerably. On a system with 30k macs we see fdb dumps spanning across more than 300 skbs. To fix the problem, this patch replaces the existing single fdb marker with three markers: netdev hash entries, netdevs and fdb index to continue where we left off instead of restarting from the first netdev. This is consistent with link dumps. In the process of fixing the performance issue, this patch also re-implements fix done by commit 472681d57a5d ("net: ndo_fdb_dump should report -EMSGSIZE to rtnl_fdb_dump") (with an internal fix from Wilson Kok) in the following ways: - change ndo_fdb_dump handlers to return error code instead of the last fdb index - use cb->args strictly for dump frag markers and not error codes. This is consistent with other dump functions.

* bridge: switchdev: Add forward mark support for stacked devicesIdo Schimmel2016-08-261-85/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | switchdev_port_fwd_mark_set() is used to set the 'offload_fwd_mark' of port netdevs so that packets being flooded by the device won't be flooded twice. It works by assigning a unique identifier (the ifindex of the first bridge port) to bridge ports sharing the same parent ID. This prevents packets from being flooded twice by the same switch, but will flood packets through bridge ports belonging to a different switch. This method is problematic when stacked devices are taken into account, such as VLANs. In such cases, a physical port netdev can have upper devices being members in two different bridges, thus requiring two different 'offload_fwd_mark's to be configured on the port netdev, which is impossible. The main problem is that packet and netdev marking is performed at the physical netdev level, whereas flooding occurs between bridge ports, which are not necessarily port netdevs. Instead, packet and netdev marking should really be done in the bridge driver with the switch driver only telling it which packets it already forwarded. The bridge driver will mark such packets using the mark assigned to the ingress bridge port and will prevent the packet from being forwarded through any bridge port sharing the same mark (i.e. having the same parent ID). Remove the current switchdev 'offload_fwd_mark' implementation and instead implement the proposed method. In addition, make rocker - the sole user of the mark - use the proposed method.

* switchdev: Require RTNL mutex to be held when sending FDB notificationsIdo Schimmel2016-01-281-7/+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.

* switchdev: Pass original device to port netdev driverIdo Schimmel2015-12-151-0/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the notifier_call callback of a notifier_block, change the function signature of switchdev add and del operations to: int switchdev_port_obj_add/del(struct net_device *dev, enum switchdev_obj_id id, void *obj); This allows the caller to pass a specific switchdev_obj_* structure instead of the generic switchdev_obj one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the notifier_call callback of a notifier_block, change the function signature of switchdev dump operation to: int switchdev_port_obj_dump(struct net_device *dev, enum switchdev_obj_id id, void *obj, int (*cb)(void *obj)); This allows the caller to pass and expect back a specific switchdev_obj_* structure instead of the generic switchdev_obj one. Drivers implementation of dump operation can now expect this specific structure and call the callback with it. Drivers have been changed accordingly.

* | net: switchdev: remove dev from switchdev_obj cbVivien Didelot2015-09-291-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | The net_device associated to a dump operation does not have to be passed to the callback. switchdev stores it in a superset struct, if needed. Also some drivers (such as DSA drivers) may not have easy access to it. This will simplify pushing the callback function down to the drivers.

* | net: switchdev: move dev in switchdev_fdb_dumpVivien Didelot2015-09-291-1/+3
| | | | | | | | | | | | | | | | | | | | The FDB dump callback requires the related net_device so move it to the struct switchdev_fdb_dump superset instead of using a callback param. With this done, it'll be simpler to change the dump function signature. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S. Miller <davem@davemloft.net>
