net: sched: Make FIFO Qdisc offloadable Invoke ndo_setup_tc() as appropriate to signal init / replacement, destroying and dumping of pFIFO / bFIFO Qdisc. A lot of the FIFO logic is used for pFIFO_head_drop as well, but that's a semantically very different Qdisc that isn't really in the same boat as pFIFO / bFIFO. Split some of the functions to keep the Qdisc intact.

net: sched: Introduce ingress classification function TC multi chain configuration can cause offloaded tc chains to miss in hardware after jumping to some chain. In such cases the software should continue from the chain that missed in hardware, as the hardware may have manipulated the packet and updated some counters. Currently a single tcf classification function serves both ingress and egress. However, multi chain miss processing (get tc skb extension on hw miss, set tc skb extension on tc miss) should happen only on ingress. Refactor the code to use ingress classification function, and move setting the tc skb extension from general classification to it, as a prestep for supporting the hw miss scenario.

net_sched: fix ops->bind_class() implementations The current implementations of ops->bind_class() are merely searching for classid and updating class in the struct tcf_result, without invoking either of cl_ops->bind_tcf() or cl_ops->unbind_tcf(). This breaks the design of them as qdisc's like cbq use them to count filters too. This is why syzbot triggered the warning in cbq_destroy_class(). In order to fix this, we have to call cl_ops->bind_tcf() and cl_ops->unbind_tcf() like the filter binding path. This patch does so by refactoring out two helper functions __tcf_bind_filter() and __tcf_unbind_filter(), which are lockless and accept a Qdisc pointer, then teaching each implementation to call them correctly. Note, we merely pass the Qdisc pointer as an opaque pointer to each filter, they only need to pass it down to the helper functions without understanding it at all.

net: sched: refactor block offloads counter usage Without rtnl lock protection filters can no longer safely manage block offloads counter themselves. Refactor cls API to protect block offloadcnt with tcf_block->cb_lock that is already used to protect driver callback list and nooffloaddevcnt counter. The counter can be modified by concurrent tasks by new functions that execute block callbacks (which is safe with previous patch that changed its type to atomic_t), however, block bind/unbind code that checks the counter value takes cb_lock in write mode to exclude any concurrent modifications. This approach prevents race conditions between bind/unbind and callback execution code but allows for concurrency for tc rule update path. Move block offload counter, filter in hardware counter and filter flags management from classifiers into cls hardware offloads API. Make functions tcf_block_offload_{inc|dec}() and tc_cls_offload_cnt_update() to be cls API private. Implement following new cls API to be used instead: tc_setup_cb_add() - non-destructive filter add. If filter that wasn't already in hardware is successfully offloaded, increment block offloads counter, set filter in hardware counter and flag. On failure, previously offloaded filter is considered to be intact and offloads counter is not decremented. tc_setup_cb_replace() - destructive filter replace. Release existing filter block offload counter and reset its in hardware counter and flag. Set new filter in hardware counter and flag. On failure, previously offloaded filter is considered to be destroyed and offload counter is decremented. tc_setup_cb_destroy() - filter destroy. Unconditionally decrement block offloads counter. tc_setup_cb_reoffload() - reoffload filter to single cb. Execute cb() and call tc_cls_offload_cnt_update() if cb() didn't return an error. Refactor all offload-capable classifiers to atomically offload filters to hardware, change block offload counter, and set filter in hardware counter and flag by means of the new cls API functions.

Update drivers too so they do not need to lshift the priority field of the flow_cls_common_offload object. The stmmac driver is an exception, since this code assumes the tc software priority is fine, therefore, lshift it just to be conservative.

net: flow_offload: add flow_block_cb_setup_simple() Most drivers do the same thing to set up the flow block callbacks, this patch adds a helper function to do this. This preparation patch reduces the number of changes to adapt the existing drivers to use the flow block callback API. This new helper function takes a flow block list per-driver, which is set to NULL until this driver list is used. This patch also introduces the flow_block_command and flow_block_binder_type enumerations, which are renamed to use FLOW_BLOCK_* in follow up patches. There are three definitions (aliases) in order to reduce the number of updates in this patch, which go away once drivers are fully adapted to use this flow block API.

net: sched: refactor reinsert action The TC_ACT_REINSERT return type was added as an in-kernel only option to allow a packet ingress or egress redirect. This is used to avoid unnecessary skb clones in situations where they are not required. If a TC hook returns this code then the packet is 'reinserted' and no skb consume is carried out as no clone took place. This return type is only used in act_mirred. Rather than have the reinsert called from the main datapath, call it directly in act_mirred. Instead of returning TC_ACT_REINSERT, change the type to the new TC_ACT_CONSUMED which tells the caller that the packet has been stolen by another process and that no consume call is required. Moving all redirect calls to the act_mirred code is in preparation for tracking recursion created by act_mirred.

net: sched: remove NET_CLS_IND config option This config option makes only couple of lines optional. Two small helpers and an int in couple of cls structs.

net/sched: remove block pointer from common offload structure Based on feedback from Jiri avoid carrying a pointer to the tcf_block structure in the tc_cls_common_offload structure.
