net/sched: act_gate: use percpu stats

2023-02-16T09:39:28+00:00

The tc action act_gate was using shared stats, move it to percpu stats. tdc results: 1..12 ok 1 5153 - Add gate action with priority and sched-entry ok 2 7189 - Add gate action with base-time ok 3 a721 - Add gate action with cycle-time ok 4 c029 - Add gate action with cycle-time-ext ok 5 3719 - Replace gate base-time action ok 6 d821 - Delete gate action with valid index ok 7 3128 - Delete gate action with invalid index ok 8 7837 - List gate actions ok 9 9273 - Flush gate actions ok 10 c829 - Add gate action with duplicate index ok 11 3043 - Add gate action with invalid index ok 12 2930 - Add gate action with cookie Reviewed-by: Jamal Hadi Salim Signed-off-by: Pedro Tammela Signed-off-by: Paolo Abeni

net: sched: act_gate: get rid of tcf_gate_walker and tcf_gate_search

net/sched: act_api: Add extack to offload_act_setup() callback

2022-04-08T12:45:43+00:00

The callback is used by various actions to populate the flow action structure prior to offload. Pass extack to this callback so that the various actions will be able to report accurate error messages to user space. Signed-off-by: Ido Schimmel Reviewed-by: Petr Machata Signed-off-by: David S.

flow_offload: allow user to offload tc action to net device

2021-12-19T14:08:48+00:00

Use flow_indr_dev_register/flow_indr_dev_setup_offload to offload tc action. We need to call tc_cleanup_flow_action to clean up tc action entry since in tc_setup_action, some actions may hold dev refcnt, especially the mirror action.

flow_offload: add ops to tc_action_ops for flow action setup

2021-12-19T14:08:48+00:00

Add a new ops to tc_action_ops for flow action setup. Refactor function tc_setup_flow_action to use this new ops. We make this change to facilitate to add standalone action module.

net_sched: refactor TC action init API

2021-08-02T09:24:38+00:00

TC action ->init() API has 10 parameters, it becomes harder to read. Some of them are just boolean and can be replaced by flags. Similarly for the internal API tcf_action_init() and tcf_exts_validate(). This patch converts them to flags and fold them into the upper 16 bits of "flags", whose lower 16 bits are still reserved for user-space. More specifically, the following kernel flags are introduced: TCA_ACT_FLAGS_POLICE replace 'name' in a few contexts, to distinguish whether it is compatible with policer. TCA_ACT_FLAGS_BIND replaces 'bind', to indicate whether this action is bound to a filter. TCA_ACT_FLAGS_REPLACE replaces 'ovr' in most contexts, means we are replacing an existing action. TCA_ACT_FLAGS_NO_RTNL replaces 'rtnl_held' but has the opposite meaning, because we still hold RTNL in most cases. The only user-space flag TCA_ACT_FLAGS_NO_PERCPU_STATS is untouched and still stored as before. I have tested this patch with tdc and I do not see any failure related to this patch.

Rejecting non-native endian BTF overlapped with the addition of support for it. The rest were more simple overlapping changes, except the renesas ravb binding update, which had to follow a file move as well as a YAML conversion. Signed-off-by: David S. Miller
