net: flow_offload: add flow_block structure and use it

2019-07-20T04:27:45Z

This object stores the flow block callbacks that are attached to this block. Update flow_block_cb_lookup() to take this new object. This patch restores the block sharing feature.

net: flow_offload: rename tc_setup_cb_t to flow_setup_cb_t

2019-07-20T04:27:45Z

Rename this type definition and adapt users. Signed-off-by: Pablo Neira Ayuso Acked-by: Jiri Pirko Signed-off-by: David S. Miller

net: flow_offload: remove netns parameter from flow_block_cb_alloc()

2019-07-20T04:27:45Z

No need to annotate the netns on the flow block callback object, flow_block_cb_is_busy() already checks for used blocks. Fixes: d63db30c8537 ("net: flow_offload: add flow_block_cb_alloc() and flow_block_cb_free()") Signed-off-by: Pablo Neira Ayuso Acked-by: Jiri Pirko Signed-off-by: David S. Miller

net: flow_offload: rename tc_cls_flower_offload to flow_cls_offload

2019-07-09T21:38:51Z

And any other existing fields in this structure that refer to tc. Specifically: * tc_cls_flower_offload_flow_rule() to flow_cls_offload_flow_rule(). * TC_CLSFLOWER_* to FLOW_CLS_*. * tc_cls_common_offload to tc_cls_common_offload. Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

net: flow_offload: add flow_block_cb_is_busy() and use it

2019-07-09T21:38:50Z

This patch adds a function to check if flow block callback is already in use. Call this new function from flow_block_cb_setup_simple() and from drivers. Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

drivers: net: use flow block API

2019-07-09T21:38:50Z

This patch updates flow_block_cb_setup_simple() to use the flow block API. Several drivers are also adjusted to use it. This patch introduces the per-driver list of flow blocks to account for blocks that are already in use. Remove tc_block_offload alias. Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

net: flow_offload: add flow_block_cb_{priv, incref, decref}()

2019-07-09T21:38:50Z

This patch completes the flow block API to introduce: * flow_block_cb_priv() to access callback private data. * flow_block_cb_incref() to bump reference counter on this flow block. * flow_block_cb_decref() to decrement the reference counter. These functions are taken from the existing tcf_block_cb_priv(), tcf_block_cb_incref() and tcf_block_cb_decref(). Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

net: flow_offload: add list handling functions

2019-07-09T21:38:50Z

This patch adds the list handling functions for the flow block API: * flow_block_cb_lookup() allows drivers to look up for existing flow blocks. * flow_block_cb_add() adds a flow block to the per driver list to be registered by the core. * flow_block_cb_remove() to remove a flow block from the list of existing flow blocks per driver and to request the core to unregister this. The flow block API also annotates the netns this flow block belongs to. Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

net: flow_offload: add flow_block_cb_alloc() and flow_block_cb_free()

2019-07-09T21:38:50Z

Add a new helper function to allocate flow_block_cb objects. Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

net: flow_offload: rename TCF_BLOCK_BINDER_TYPE_* to FLOW_BLOCK_BINDER_TYPE_*

2019-07-09T21:38:50Z

Rename from TCF_BLOCK_BINDER_TYPE_* to FLOW_BLOCK_BINDER_TYPE_* and remove temporary tcf_block_binder_type alias. Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller
