flow_offload: Move rhashtable inclusion to the source file

2020-07-24T22:17:22Z

I noticed that touching linux/rhashtable.h causes lib/vsprintf.c to be rebuilt. This dependency came through a bogus inclusion in the file net/flow_offload.h. This patch moves it to the right place. This patch also removes a lingering rhashtable inclusion in cls_api created by the same commit. Fixes: 4e481908c51b ("flow_offload: move tc indirect block to...")

net: flow_offload: fix flow_indr_dev_unregister path

2020-06-20T03:12:58Z

If the representor is removed, then identify the indirect flow_blocks that need to be removed by the release callback and the port representor structure. To identify the port representor structure, a new indr.cb_priv field needs to be introduced. The flow_block also needs to be removed from the driver list from the cleanup path.

net: remove indirect block netdev event registration

2020-06-01T18:41:50Z

Drivers do not register to netdev events to set up indirect blocks anymore. Remove __flow_indr_block_cb_register() and __flow_indr_block_cb_unregister(). The frontends set up the callbacks through flow_indr_dev_setup_block() Signed-off-by: Pablo Neira Ayuso Signed-off-by: David S. Miller

net: flow_offload: consolidate indirect flow_block infrastructure

2020-06-01T18:41:12Z

Tunnel devices provide no dev->netdev_ops->ndo_setup_tc(...) interface. The tunnel device and route control plane does not provide an obvious way to relate tunnel and physical devices. This patch allows drivers to register a tunnel device offload handler for the tc and netfilter frontends through flow_indr_dev_register() and flow_indr_dev_unregister(). The frontend calls flow_indr_dev_setup_offload() that iterates over the list of drivers that are offering tunnel device hardware offload support and it sets up the flow block for this tunnel device. If the driver module is removed, the indirect flow_block ends up with a stale callback reference. The module removal path triggers the dev_shutdown() path to remove the qdisc and the flow_blocks for the physical devices. However, this is not useful for tunnel devices, where relation between the physical and the tunnel device is not explicit. This patch introduces a cleanup callback that is invoked when the driver module is removed to clean up the tunnel device flow_block. This patch defines struct flow_block_indr and it uses it from flow_block_cb to store the information that front-end requires to perform the flow_block_cb cleanup on module removal.

net: flow_offload: simplify hw stats check handling

2020-05-22T22:52:08Z

Make FLOW_ACTION_HW_STATS_DONT_CARE be all bits, rather than none, so that drivers and __flow_action_hw_stats_check can use simple bitwise checks. Pre-fill all actions with DONT_CARE in flow_rule_alloc(), rather than relying on implicit semantics of zero from kzalloc, so that callers which don't configure action stats themselves (i.e. netfilter) get the correct behaviour by default. Only the kernel's internal API semantics change; the TC uAPI is unaffected. v4: move DONT_CARE setting to flow_rule_alloc() for robustness and simplicity. v3: set DONT_CARE in nft and ct offload. v2: rebased on net-next, removed RFC tags.

net: flow_offload: skip hw stats check for FLOW_ACTION_HW_STATS_DONT_CARE

2020-05-07T03:13:10Z

This patch adds FLOW_ACTION_HW_STATS_DONT_CARE which tells the driver that the frontend does not need counters, this hw stats type request never fails. The FLOW_ACTION_HW_STATS_DISABLED type explicitly requests the driver to disable the stats, however, if the driver cannot disable counters, it bails out. TCA_ACT_HW_STATS_* maintains the 1:1 mapping with FLOW_ACTION_HW_STATS_* except by disabled which is mapped to FLOW_ACTION_HW_STATS_DISABLED (this is 0 in tc). Add tc_act_hw_stats() to perform the mapping between TCA_ACT_HW_STATS_* and FLOW_ACTION_HW_STATS_*.
