Create a new FIB entry type for blackhole routes and set it in case the type of the notified route is 'RTN_BLACKHOLE'. Program such routes with a discard action and mark them as offloaded since the device is dropping the packets instead of the kernel. Signed-off-by:

Florian Fainelli says: ==================== net: Introduce ndo_get_port_parent_id() Based on discussion with Ido and feedback from Jakub there are clearly two classes of users that implement SWITCHDEV_ATTR_ID_PORT_PARENT_ID: - PF/VF drivers which typically only implement return the port's parent ID, yet have to implement switchdev_port_attr_get() just for that - Ethernet switch drivers: mlxsw, ocelot, DSA, etc. which implement more attributes which we want to be able to eventually veto in the context of the caller, thus making them candidates for using a blocking notifier chain Changes in v4: - remove superfluous net/switchdev.h inclusions in a few files - added Jiri's Acked-by where given - removed err = -EOPNOTSUPP initializations - changed according to Jiri's suggestion in net/ipv4/ipmr.c Changes in v3: - keep ethsw's switchdev_ops assignment - remove inclusion of net/switchdev.h in netdevsim which is no longer necesary Changes in v2: - resolved build failures spotted by kbuild test robot - added helpers functions into the core network device layer: dev_get_port_parent_id() and netdev_port_same_parent_id(); - added support for recursion to lower devices Changes from RFC: - introduce a ndo_get_port_parent_id() and convert all relevant drivers to use it - get rid of SWITCHDEV_ATTR_ID_PORT_PARENT_ID A subsequent set of patches will convert switchdev_port_attr_set() to use a blocking notifier call, and still get rid of switchdev_port_attr_get() altogether. ==================== Signed-off-by: -

Now that we have a dedicated NDO for getting a port's parent ID, get rid of SWITCHDEV_ATTR_ID_PORT_PARENT_ID and convert all callers to use the NDO exclusively. This is a preliminary change to getting rid of switchdev_ops eventually. Signed-off-by:

BNXT only supports SWITCHDEV_ATTR_ID_PORT_PARENT_ID, which makes it a great candidate to be converted to use the ndo_get_port_parent_id() NDO instead of implementing switchdev_port_attr_get(). The conversion is straight forward here since the PF and VF code use the same getter. Since bnxt makes uses of switchdev_port_same_parent_id() convert it to use netdev_port_same_parent_id().

In preparation for getting rid of switchdev_ops, create a dedicated NDO operation for getting the port's parent identifier. There are essentially two classes of drivers that need to implement getting the port's parent ID which are VF/PF drivers with a built-in switch, and pure switchdev drivers such as mlxsw, ocelot, dsa etc. We introduce a helper function: dev_get_port_parent_id() which supports recursion into the lower devices to obtain the first port's parent ID. Convert the bridge, core and ipv4 multicast routing code to check for such ndo_get_port_parent_id() and call the helper function when valid before falling back to switchdev_port_attr_get(). This will allow us to convert all relevant drivers in one go instead of having to implement both switchdev_port_attr_get() and ndo_get_port_parent_id() operations, then get rid of switchdev_port_attr_get().

Instead of allocating page fragments via the network stack, use the page allocator directly. For now, we consume one page for each Rx buffer. With the new memory model we are free to consider adding more XDP support. Performance decreases slightly in some IP forwarding cases. No visible effect on termination traffic. The driver memory footprint increases as a result of this change, but it is still small enough to not really matter. Another side effect is that now Rx buffer alignment requirements are naturally satisfied without any additional actions needed. Remove alignment related code, except in the buffer layout information conveyed to MC, as hardware still needs to know the alignment value we guarantee. Signed-off-by:

Pablo Neira Ayuso says: ==================== add flow_rule infrastructure This patchset, as is, allows us to reuse the driver codebase to configure ACL hardware offloads for the ethtool_rxnfc and the TC flower interfaces. A few clients for this infrastructure are presented, such as the bcm_sf2 and the qede drivers, for reference. Moreover all of the existing drivers in the tree are converted to use this infrastructure. This patchset is re-using the existing flow dissector infrastructure that was introduced by Jiri Pirko et al. so the amount of abstractions that this patchset adds are minimal. Well, just a few wrapper structures for the selector side of the rules. And, in order to express actions, this patchset exposes an action API that is based on the existing TC action infrastructure and what existing drivers already support on that front. v7: This patchset is a rebase on top of the net-next tree, after addressing questions and feedback from driver developers in the last batch. ==================== Signed-off-by: -

The qede driver supports for ethtool_rx_flow_spec and flower, both codebases look very similar. This patch uses the ethtool_rx_flow_rule() infrastructure to remove the duplicated ethtool_rx_flow_spec parser and consolidate ACL offload support around the flow_rule infrastructure. Furthermore, more code can be consolidated by merging qede_add_cls_rule() and qede_add_tc_flower_fltr(), these two functions also look very similar. This driver currently provides simple ACL support, such as 5-tuple matching, drop policy and queue to CPU. Drivers that support more features can benefit from this infrastructure to save even more redundant codebase. Signed-off-by:

This is a preparation patch to reuse the existing TC flower codebase from ethtool_rx_flow_spec. This patch is merely moving the core ethtool_rx_flow_spec parser after tc flower offload driver code so we can skip a few forward function declarations in the follow up patch. Signed-off-by:

This patch adds a function to translate the ethtool_rx_flow_spec structure to the flow_rule representation. This allows us to reuse code from the driver side given that both flower and ethtool_rx_flow interfaces use the same representation. This patch also includes support for the flow type flags FLOW_EXT, FLOW_MAC_EXT and FLOW_RSS. The ethtool_rx_flow_spec_input wrapper structure is used to convey the rss_context field, that is away from the ethtool_rx_flow_spec structure, and the ethtool_rx_flow_spec structure. Signed-off-by:

These actions need to be added to support the ethtool_rx_flow interface. The queue action includes a field to specify the RSS context, that is set via FLOW_RSS flow type flag and the rss_context field in struct ethtool_rxnfc, plus the corresponding queue index. FLOW_RSS implies that rss_context is non-zero, therefore, queue.ctx == 0 means that FLOW_RSS was not set. Also add a field to store the vf index which is stored in the ethtool_rxnfc ring_cookie field. Signed-off-by:

This patch adds pedit_headers_action structure to store the result of parsing tc pedit actions. Then, it calls alloc_tc_pedit_action() to populate the mlx5e hardware intermediate representation once all actions have been parsed. This patch comes in preparation for the new flow_action infrastructure, where each packet mangling comes in an separated action, ie. not packed as in tc pedit. Signed-off-by:

This patch wraps the dissector key and mask - that flower uses to represent the matching side - around the flow_match structure. To avoid a follow up patch that would edit the same LoCs in the drivers, this patch also wraps this new flow match structure around the flow rule object. This new structure will also contain the flow actions in follow up patches. This introduces two new interfaces: bool flow_rule_match_key(rule, dissector_id) that returns true if a given matching key is set on, and: flow_rule_match_XYZ(rule, &match); To fetch the matching side XYZ into the match container structure, to retrieve the key and the mask with one single call.
