      Merge branch 'cls-hw-offload-rtnl' · 72991b56
      David S. Miller authored
      Vlad Buslov says:
      
      ====================
      Refactor cls hardware offload API to support rtnl-independent drivers
      
      Currently, all cls API hardware offloads driver callbacks require caller
      to hold rtnl lock when calling them. This patch set introduces new API
      that allows drivers to register callbacks that are not dependent on rtnl
      lock and unlocked classifiers to offload filters without obtaining rtnl
      lock first, which is intended to allow offloading tc rules in parallel.
      
      Recently, new rtnl registration flag RTNL_FLAG_DOIT_UNLOCKED was added.
      TC rule update handlers (RTM_NEWTFILTER, RTM_DELTFILTER, etc.) are
      already registered with this flag and only take rtnl lock when qdisc or
      classifier requires it. Classifiers can indicate that their ops
      callbacks don't require caller to hold rtnl lock by setting the
      TCF_PROTO_OPS_DOIT_UNLOCKED flag. Unlocked implementation of flower
      classifier is now upstreamed. However, this implementation still obtains
      rtnl lock before calling hardware offloads API.
      
      Implement following cls API changes:
      
      - Introduce new "unlocked_driver_cb" flag to struct flow_block_offload
        to allow registering and unregistering block hardware offload
        callbacks that do not require caller to hold rtnl lock. Drivers that
        doesn't require users of its tc offload callbacks to hold rtnl lock
        sets the flag to true on block bind/unbind. Internally tcf_block is
        extended with additional lockeddevcnt counter that is used to count
        number of devices that require rtnl lock that block is bound to. When
        this counter is zero, tc_setup_cb_*() functions execute callbacks
        without obtaining rtnl lock.
      
      - Extend cls API single hardware rule update tc_setup_cb_call() function
        with tc_setup_cb_add(), tc_setup_cb_replace(), tc_setup_cb_destroy()
        and tc_setup_cb_reoffload() functions. These new APIs are needed to
        move management of block offload counter, filter in hardware counter
        and flag from classifier implementations to cls API, which is now
        responsible for managing them in concurrency-safe manner. Access to
        cb_list from callback execution code is synchronized by obtaining new
        'cb_lock' rw_semaphore in read mode, which allows executing callbacks
        in parallel, but excludes any modifications of data from
        register/unregister code. tcf_block offloads counter type is changed
        to atomic integer to allow updating the counter concurrently.
      
      - Extend classifier ops with new ops->hw_add() and ops->hw_del()
        callbacks which are used to notify unlocked classifiers when filter is
        successfully added or deleted to hardware without releasing cb_lock.
        This is necessary to update classifier state atomically with callback
        list traversal and updating of all relevant counters and allows
        unlocked classifiers to synchronize with concurrent reoffload without
        requiring any changes to driver callback API implementations.
      
      New tc flow_action infrastructure is also modified to allow its user to
      execute without rtnl lock protection. Function tc_setup_flow_action() is
      modified to conditionally obtain rtnl lock before accessing action
      state. Action data that is accessed by reference is either copied or
      reference counted to prevent concurrent action overwrite from
      deallocating it. New function tc_cleanup_flow_action() is introduced to
      cleanup/release all such data obtained by tc_setup_flow_action().
      
      Flower classifier (only unlocked classifier at the moment) is modified
      to use new cls hardware offloads API and no longer obtains rtnl lock
      before calling it.
