[ Upstream commit 24cb7055 ] rtnl_fdb_dump always expects an index to be returned by the ndo_fdb_dump op, but when CONFIG_NET_SWITCHDEV is off, it returns an error. Fix that by returning the given unmodified idx. A similar fix was 0890cf6c ("switchdev: fix return value of switchdev_port_fdb_dump in case of error") but for the CONFIG_NET_SWITCHDEV=y case. Fixes: 45d4122c ("switchdev: add support for fdb add/del/dump via switchdev_port_obj ops.") Signed-off-by:

The address in the switchdev_obj_fdb structure is currently represented as a pointer. Replacing it for a 6-byte array allows switchdev to carry addresses directly read from hardware registers, not stored by the switch chip driver (as in Rocker). Signed-off-by:

skb->offload_fwd_mark and dev->offload_fwd_mark are 32-bit and should be unique for device and may even be unique for a sub-set of ports within device, so add switchdev helper function to generate unique marks based on port's switch ID and group_ifindex. group_ifindex would typically be the container dev's ifindex, such as the bridge's ifindex. The generator uses a global hash table to store offload_fwd_marks hashed by {switch ID, group_ifindex} key. Signed-off-by:Jiri Pirko <jiri@resnulli.us> Signed-off-by:

- introduce port fdb obj and generic switchdev_port_fdb_add/del/dump() - use switchdev_port_fdb_add/del/dump in rocker/team/bonding ndo ops. - add support for fdb obj in switchdev_port_obj_add/del/dump() - switch rocker to implement fdb ops via switchdev_ops v3: updated to sync with named union changes.

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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:

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.

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. Signed-off-by:

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. Signed-off-by:
