The IPv4 FIB ops convert nicely to the switchdev objs and we're left with only four switchdev ops: port get/set and port add/del. Other objs will follow, such as FDB. So go ahead and convert IPv4 FIB over to switchdev obj for consistency, anticipating more objs to come.

Like bridge_setlink, add switchdev wrapper to handle bridge_getlink and call into port driver to get port attrs. For now, only BR_LEARNING and BR_LEARNING_SYNC are returned. To add more, we'll probably want to break away from ndo_dflt_bridge_getlink() and build the netlink skb directly in the switchdev code.

Add new switchdev_port_bridge_setlink that can be used by drivers implementing .ndo_bridge_setlink to set switchdev bridge attributes. Basically turn the raw rtnl_bridge_setlink netlink into switchdev attr sets. Proper netlink attr policy checking is done on the protinfo part of the netlink msg. Currently, for protinfo, only bridge port attrs BR_LEARNING and BR_LEARNING_SYNC are parsed and passed to port driver. For afspec, VLAN objs are passed so switchdev driver can set VLANs assigned to SELF. To illustrate with iproute2 cmd, we have: bridge vlan add vid 10 dev sw1p1 self master To add VLAN 10 to port sw1p1 for both the bridge (master) and the device (self).

Like switchdev attr get/set, add new switchdev obj add/del. switchdev objs will be things like VLANs or FIB entries, so add/del fits better for objects than get/set used for attributes. Use same two-phase prepare-commit transaction model as in attr set.

STP update is just a settable port attribute, so convert switchdev_port_stp_update to an attr set. For DSA, the prepare phase is skipped and STP updates are only done in the commit phase. This is because currently the DSA drivers don't need to allocate any memory for STP updates and the STP update will not fail to HW (unless something horrible goes wrong on the MDIO bus, in which case the prepare phase wouldn't have been able to predict anyway).

Switch ID is just a gettable port attribute. Convert switchdev op switchdev_parent_id_get to a switchdev attr. Note: for sysfs and netlink interfaces, SWITCHDEV_ATTR_PORT_PARENT_ID is called with SWITCHDEV_F_NO_RECUSE to limit switch ID user-visiblity to only port netdevs. So when a port is stacked under bond/bridge, the user can only query switch id via the switch ports, but not via the upper devices Signed-off-by: NScott Feldman <sfeldma@gmail.com> Acked-by: NJiri Pirko <jiri@resnulli.us> Signed-off-by: NDavid S.

Add two new swdev ops for get/set switch port attributes. Most swdev interactions on a port are gets or sets on port attributes, so rather than adding ops for each attribute, let's define clean get/set ops for all attributes, and then we can have clear, consistent rules on how attributes propagate on stacked devs. Add the basic algorithms for get/set attr ops. Use the same recusive algo to walk lower devs we've used for STP updates, for example. For get, compare attr value for each lower dev and only return success if attr values match across all lower devs. For sets, set the same attr value for all lower devs. We'll use a two-phase prepare-commit transaction model for sets. In the first phase, the driver(s) are asked if attr set is OK. If all OK, the commit attr set in second phase. A driver would NACK the prepare phase if it can't set the attr due to lack of resources or support, within it's control. RTNL lock must be held across both phases because we'll recurse all lower devs first in prepare phase, and then recurse all lower devs again in commit phase. If any lower dev fails the prepare phase, we need to abort the transaction for all lower devs. If lower dev recusion isn't desired, allow a flag SWITCHDEV_F_NO_RECURSE to indicate get/set only work on port (lowest) device.

make it same as the netdev_switch_port_bridge_setlink/dellink api (ie traverse lowerdevs to get to the switch port). removes "WARN_ON(!ops->ndo_switch_parent_id_get)" because direct bridge ports can be stacked netdevices (like bonds and team of switch ports) which may not implement this ndo. v2 to v3: - remove changes to bond and team. Bring back the transparently following lowerdevs like i initially had for setlink/getlink (http://www.spinics.net/lists/netdev/msg313436.html) dave and scott feldman also seem to prefer it be that way and move to non-transparent way of doing things if we see a problem down the lane. v3 to v4: - fix ret initialization v4 to v5: - return err on first failure (scott feldman) v5 to v6: - change variable name (err) and initialize to -EOPNOTSUPP (scott feldman).

Call into the switchdev driver any time an IPv4 fib entry is added/modified/deleted from the kernel's FIB. The switchdev driver may or may not install the route to the offload device. In the case where the driver tries to install the route and something goes wrong (device's routing table is full, etc), then all of the offloaded routes will be flushed from the device, route forwarding falls back to the kernel, and no more routes are offloading. We can refine this logic later. For now, use the simplist model of offloading routes up to the point of failure, and then on failure, undo everything and mark IPv4 offloading disabled.

Flesh out ndo wrappers to call into device driver. To call into device driver, the wrapper must interate over route's nexthops to ensure all nexthop devs belong to the same switch device. Currently, there is no support for route's nexthops spanning offloaded and non-offloaded devices, or spanning ports of multiple offload devices. Since switch device ports may be stacked under virtual interfaces (bonds and/or bridges), and the route's nexthop may be on the virtual interface, the wrapper will traverse the nexthop dev down to the base dev. It's the base dev that's passed to the switchdev driver's ndo ops. Signed-off-by: NScott Feldman <sfeldma@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This patch adds two new api's netdev_switch_port_bridge_setlink and netdev_switch_port_bridge_dellink to offload bridge port attributes to switch port (The names of the apis look odd with 'switch_port_bridge', but am more inclined to change the prefix of the api to something else. Will take any suggestions). The api's look at the NETIF_F_HW_SWITCH_OFFLOAD feature flag to pass bridge port attributes to the port device.
