In Spectrum-2 there is a different implementation of KVD linear management. Unlike in Spectrum where there is a single index space, in Spectrum-2 the indexes are per-resource. Also there is need to explicitly tell HW that an entry is no longer used. So push out the existing implementation into spectrum1_kvdl.c and prepare ops infrastructure to allow new implementation in a follow-up.

This resolves race during initialization where the resources with ops are registered before driver and the structures used by occ_get op is initialized. So keep occ_get callbacks registered only when all structs are initialized. The example flows, as it is in mlxsw: 1) driver load/asic probe: mlxsw_core -> mlxsw_sp_resources_register -> mlxsw_sp_kvdl_resources_register -> devlink_resource_register IDX mlxsw_spectrum -> mlxsw_sp_kvdl_init -> mlxsw_sp_kvdl_parts_init -> mlxsw_sp_kvdl_part_init -> devlink_resource_size_get IDX (to get the current setup size from devlink) -> devlink_resource_occ_get_register IDX (register current occupancy getter) 2) reload triggered by devlink command: -> mlxsw_devlink_core_bus_device_reload -> mlxsw_sp_fini -> mlxsw_sp_kvdl_fini -> devlink_resource_occ_get_unregister IDX (struct mlxsw_sp *mlxsw_sp is freed at this point, call to occ get which is using mlxsw_sp would cause use-after free) -> mlxsw_sp_init -> mlxsw_sp_kvdl_init -> mlxsw_sp_kvdl_parts_init -> mlxsw_sp_kvdl_part_init -> devlink_resource_size_get IDX (to get the current setup size from devlink) -> devlink_resource_occ_get_register IDX (register current occupancy getter) Fixes: d9f9b9a4 ("devlink: Add support for resource abstraction") Signed-off-by: NJiri Pirko <jiri@mellanox.com> Signed-off-by: NDavid S.

In commit 14530746 ("devlink: Remove top_hierarchy arg to devlink_resource_register"), the "top_hierarchy" parameter to devlink_resource_register() was removed in favor of using the parameter "parent_resource_id" exclusively to determine who the parent is. The root node's resource ID for this purpose is DEVLINK_RESOURCE_ID_PARENT_TOP with the value 0. It is therefore problematic that the resource MLXSW_SP_RESOURCE_KVD has also ID of 0. Fix this by numbering driver-specific resources from 1.

The Spectrum ASIC doesn't support mirroring more than once from a single binding point (which is a port-direction pair). Therefore detect that a second binding of a given binding point is attempted. To that end, extend struct mlxsw_sp_span_inspected_port to track whether a given binding point is bound or not. Extend mlxsw_sp_span_entry_port_find() to look for ports based on the full unique key: port number, direction, and boundness. Besides fixing the overt bug where configured mirrors are not offloaded, this also fixes a more subtle bug: mlxsw_sp_span_inspected_port_del() just defers to mlxsw_sp_span_entry_bound_port_find(), and that used to find the first port with the right number (disregarding the type). Thus by adding and removing egress and ingress mirrors in the right order, one could trick the system into believing it has no egress mirrors when in fact it did have some. That then caused that mlxsw_sp_span_port_mtu_update() didn't update mirroring buffer when MTU was changed.

One of the basic construct in the device is a port-VLAN pair, which can be bound to a FID or a RIF in order to direct packets to the bridge or the router, respectively. Since not all the netdevs are configured with a VLAN (e.g., sw1p1 vs. sw1p1.10), VID 1 is used to represent these and thus this VID can be used by both upper devices of mlxsw ports and by the driver itself. However, this VID is not reference counted and therefore might be freed prematurely, which can result in various WARNINGs. For example: $ ip link add name br0 type bridge vlan_filtering 1 $ teamd -t team0 -d -c '{"runner": {"name": "lacp"}}' $ ip link set dev team0 master br0 $ ip link set dev enp1s0np1 master team0 $ ip address add 192.0.2.1/24 dev enp1s0np1 The enslavement to team0 will fail because team0 already has an upper and thus vlan_vids_del_by_dev() will be executed as part of team's error path which will delete VID 1 from enp1s0np1 (added by br0 as PVID). The WARNING will be generated when the driver will realize it can't find VID 1 on the port and bind it to a RIF. Fix this by adding a reference count to the VLAN entries on the port, in a similar fashion to the reference counting used by the corresponding 'vlan_vid_info' structure in the 8021q driver.

Since commit 25cc72a3 ("mlxsw: spectrum: Forbid linking to devices that have uppers") the driver forbids enslavement to netdevs that already have uppers of their own, as this can result in various ordering problems. This requirement proved to be too strict for some users who need to be able to enslave ports to a bridge that already has uppers. In this case, we can allow the enslavement if the bridge is already known to us, as any configuration performed on top of the bridge was already reflected to the device.

Follow-up patches will introduce handling of more changes, and some of them carry an extack as well, but in an info structure of a different type. Though not strictly erroneous (the pointer could be cast whichever way), it makes no sense to pretend the value is always of a certain type, when in fact it isn't.
