We currently do not perform accounting in the driver and thus can't reject routes before resources are exceeded. However, in order to make users aware of the fact that routes are no longer offloaded we can return an error for routes configured after the abort mechanism was triggered.

Since commit 9776d325 ("net: Move call_fib_rule_notifiers up in fib_nl_newrule") it is possible to forbid the installation of unsupported FIB rules. Have mlxsw return an error for non-default FIB rules in addition to the existing extack message. Example: # ip rule add from 198.51.100.1 table 10 Error: mlxsw_spectrum: FIB rules not supported. Note that offload is only aborted when non-default FIB rules are already installed and merely replayed during module initialization.

When handling mirroring to a gretap or ip6gretap netdevice in mlxsw, the underlay address (i.e. the remote address of the tunnel) may be routed to a bridge. In that case, look up the resolved neighbor Ethernet address in that bridge's FDB. Then configure the offload to direct the mirrored traffic to that port, possibly with tagging.

Changes to switchdev artifact can make a SPAN entry offloadable or unoffloadable. To that end: - Listen to SWITCHDEV_FDB_*_TO_BRIDGE notifications in addition to the *_TO_DEVICE ones, to catch whatever activity is sent to the bridge (likely by mlxsw itself). On each FDB notification, respin SPAN to reconcile it with the FDB changes. - Also respin on switchdev port attribute changes (which currently covers changes to STP state of ports) and port object additions and removals.

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.

spectrum_router and spectrum_mr have several APIs that are used to manipulate configurations originating from ipmr fib notifications. Following previous patches all the protocol-specifics that are necessary for the configuration are hidden within spectrum_mr. This allows us to clean the API and make sure that other than choosing the mr_table based on the fib notification family, spectrum_router wouldn't care about the source of the notification when passing it onward to spectrum_mr. This would later allow us to leverage the same code for fib notifications originating from ip6mr.

Current multicast routing logic in driver assumes it's always meant to deal with IPv4 multicast routes, leaving several placeholders for later IPv6 support [currently usually WARN()]. This patch changes the driver's internal multicast route struct into holding a common mr_mfc instead of the IPv4 mfc_cache. The various placeholders are grouped into 2: - Functions that require only the common bits; These remain and the restriction for IPv4-only is lifted. - Function that require IPv4-specifics - for handling these functions we add sets of operations that encapsulate the protocol differences Signed-off-by: NYuval Mintz <yuvalm@mellanox.com> Signed-off-by: NIdo Schimmel <idosch@mellanox.com> Signed-off-by: NDavid S.
