The ethtool api {get|set}_settings is deprecated. We move this driver to new api {get|set}_link_ksettings. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-12-03ipv4: fib: Replay events when registering FIB notifierIdo Schimmel1-1/+7
Commit b90eb7549499 ("fib: introduce FIB notification infrastructure") introduced a new notification chain to notify listeners (f.e., switchdev drivers) about addition and deletion of routes. However, upon registration to the chain the FIB tables can already be populated, which means potential listeners will have an incomplete view of the tables. Solve that by dumping the FIB tables and replaying the events to the passed notification block. The dump itself is done using RCU in order not to starve consumers that need RTNL to make progress. The integrity of the dump is ensured by reading the FIB change sequence counter before and after the dump under RTNL. This allows us to avoid the problematic situation in which the dumping process sends a ENTRY_ADD notification following ENTRY_DEL generated by another process holding RTNL. Callers of the registration function may pass a callback that is executed in case the dump was inconsistent with current FIB tables. The number of retries until a consistent dump is achieved is set to a fixed number to prevent callers from looping for long periods of time. In case current limit proves to be problematic in the future, it can be easily converted to be configurable using a sysctl.

2016-12-03rocker: Register FIB notifier before creating portsIdo Schimmel1-4/+5
We can miss FIB notifications sent between the time the ports were created and the FIB notification block registered. Instead of receiving these notifications only when they are replayed for the FIB notification block during registration, just register the notification block before the ports are created.

2016-08-26bridge: switchdev: Add forward mark support for stacked devicesIdo Schimmel2-5/+1
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.

2016-05-17switchdev: pass pointer to fib_info instead of copyJiri Pirko1-2/+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.

2016-01-28switchdev: Require RTNL mutex to be held when sending FDB notificationsIdo Schimmel1-0/+2
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.

2015-09-29net: switchdev: abstract object in add/del opsVivien Didelot1-11/+10
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. Drivers implementation of these operations and switchdev have been changed accordingly. Signed-off-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

2015-09-29net: switchdev: pass callback to dump operationVivien Didelot1-10/+11
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.

2015-09-29net: switchdev: remove dev from switchdev_obj cbVivien Didelot1-2/+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.
