pkt_cls: add new tc cls helper to check offload flag and chain index

2018-01-26T02:23:07Z

Very few (mlxsw) upstream drivers seem to allow offload of chains other than 0. Save driver developers typing and add a helper for checking both if ethtool's TC offload flag is on and if chain is 0. This helper will set the extack appropriately in both error cases. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Signed-off-by: David S. Miller

cls_bpf: remove gen_flags from bpf_offload

2018-01-24T21:01:10Z

cls_bpf now guarantees that only device-bound programs are allowed with skip_sw. The drivers no longer pay attention to flags on filter load, therefore the bpf_offload member can be removed. If flags are needed again they should probably be added to struct tc_cls_common_offload instead. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: sched: prepare for reimplementation of tc_cls_common_offload_init()

2018-01-24T21:01:10Z

Rename the tc_cls_common_offload_init() helper function to tc_cls_common_offload_init_deprecated() and add a new implementation which also takes flags argument. We will only set extack if flags indicate that offload is forced (skip_sw) otherwise driver errors should be ignored, as they don't influence the overall filter installation. Note that we need the tc_skip_hw() helper for new version, therefore it is added later in the file. Signed-off-by: Jakub Kicinski Reviewed-by: Simon Horman Signed-off-by: David S. Miller

net: sched: create tc_can_offload_extack() wrapper

2018-01-22T21:28:32Z

Create a wrapper around tc_can_offload() that takes an additional extack pointer argument in order to output an error message if TC offload is disabled on the device. In this way, the error message is handled by the core and can be the same for all drivers. Signed-off-by: Quentin Monnet Reviewed-by: Jakub Kicinski Signed-off-by: David S. Miller

net: sched: add extack support for offload via tc_cls_common_offload

2018-01-22T21:28:32Z

Add extack support for hardware offload of classifiers. In order to achieve this, a pointer to a struct netlink_ext_ack is added to the struct tc_cls_common_offload that is passed to the callback for setting up the classifier. Function tc_cls_common_offload_init() is updated to support initialization of this new attribute. Signed-off-by: Quentin Monnet Reviewed-by: Jakub Kicinski Signed-off-by: David S. Miller

net: sched: cls: add extack support for tcf_exts_validate

2018-01-19T20:52:51Z

The tcf_exts_validate function calls the act api change callback. For preparing extack support for act api, this patch adds the extack as parameter for this function which is common used in cls implementations. Furthermore the tcf_exts_validate will call action init callback which prepares the TC action subsystem for extack support.
