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: NVivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: NDavid S.

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.

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.

This particular BUG_ON condition was checking for attr set err in the COMMIT phase, which isn't expected (it's a driver bug if PREPARE phase is OK but COMMIT fails). But BUG_ON() is too strong for this case, so change to WARN(). BUG_ON() would be warranted if the system was corrupted beyond repair, but this is not the case here.

One more missing piece of the puzzle. Add vlan dump support to switchdev port's bridge_getlink. iproute2 "bridge vlan show" cmd already knows how to show the vlans installed on the bridge and the device , but (until now) no one implemented the port vlan part of the netlink PF_BRIDGE:RTM_GETLINK msg. 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.

If CONFIG_NET_SWITCHDEV is enabled, but port driver does not implement support for IPv4 FIB add/del ops, don't fail route add/del offload operations. Route adds will not be marked as OFFLOAD. Routes will be installed in the kernel FIB, as usual. This was report/fixed by Florian when testing DSA driver with net-next on devices with L2 offload support but no L3 offload support. What he reported was an initial route installed from DHCP client would fail (route not installed to kernel FIB). This was triggering the setting of ipv4.fib_offload_disabled, which would disable route offloading after the first failure. So subsequent attempts to install the route would succeed. There is follow-on work/discussion to address the handling of route install failures, but for now, let's differentiate between no support and failed support.

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).

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.
