      ice: Fix VF spoofchk · cd6d6b83
      Brett Creeley 提交于
      There are many things wrong with the function
      ice_set_vf_spoofchk().
      
      1. The VSI being modified is the PF VSI, not the VF VSI.
      2. We are enabling Rx VLAN pruning instead of Tx VLAN anti-spoof.
      3. The spoofchk setting for each VF is not initialized correctly
         or re-initialized correctly on reset.
      
      To fix [1] we need to make sure we are modifying the VF VSI.
      This is done by using the vf->lan_vsi_idx to index into the PF's
      VSI array.
      
      To fix [2] replace setting Rx VLAN pruning in ice_set_vf_spoofchk()
      with setting Tx VLAN anti-spoof.
      
      To Fix [3] we need to make sure the initial VSI settings match what
      is done in ice_set_vf_spoofchk() for spoofchk=on. Also make sure
      this also works for VF reset. This was done by modifying ice_vsi_init()
      to account for the current spoofchk state of the VF VSI.
      
      Because of these changes, Tx VLAN anti-spoof needs to be removed
      from ice_cfg_vlan_pruning(). This is okay for the VF because this
      is now controlled from the admin enabling/disabling spoofchk. For the
      PF, Tx VLAN anti-spoof should not be set. This change requires us to
      call ice_set_vf_spoofchk() when configuring promiscuous mode for
      the VF which requires ice_set_vf_spoofchk() to move in order to prevent
      a forward declaration prototype.
      
      Also, add VLAN 0 by default when allocating a VF since the PF is unaware
      if the guest OS is running the 8021q module. Without this, MDD events will
      trigger on untagged traffic because spoofcheck is enabled by default. Due
      to this change, ignore add/delete messages for VLAN 0 from VIRTCHNL since
      this is added/deleted during VF initialization/teardown respectively and
      should not be modified.

      netdev: pass the stuck queue to the timeout handler · 0290bd29
      Michael S. Tsirkin 提交于
      This allows incrementing the correct timeout statistic without any mess.
      Down the road, devices can learn to reset just the specific queue.

      ixgbe: need_wakeup flag might not be set for Tx · 0843aa8f
      Magnus Karlsson 提交于
      The need_wakeup flag for Tx might not be set for AF_XDP sockets that
      are only used to send packets. This happens if there is at least one
      outstanding packet that has not been completed by the hardware and we
      get that corresponding completion (which will not generate an
      interrupt since interrupts are disabled in the napi poll loop) between
      the time we stopped processing the Tx completions and interrupts are
      enabled again. In this case, the need_wakeup flag will have been
      cleared at the end of the Tx completion processing as we believe we
      will get an interrupt from the outstanding completion at a later point
      in time. But if this completion interrupt occurs before interrupts
      are enable, we lose it and should at that point really have set the
      need_wakeup flag since there are no more outstanding completions that
      can generate an interrupt to continue the processing. When this
      happens, user space will see a Tx queue need_wakeup of 0 and skip
      issuing a syscall, which means will never get into the Tx processing
      again and we have a deadlock.
      
      This patch introduces a quick fix for this issue by just setting the
      need_wakeup flag for Tx to 1 all the time. I am working on a proper
      fix for this that will toggle the flag appropriately, but it is more
      challenging than I anticipated and I am afraid that this patch will
      not be completed before the merge window closes, therefore this easier
      fix for now. This fix has a negative performance impact in the range
      of 0% to 4%. Towards the higher end of the scale if you have driver
      and application on the same core and issue a lot of packets, and
      towards no negative impact if you use two cores, lower transmission
      speeds and/or a workload that also receives packets.

      igb/igc: use ktime accessors for skb->tstamp · 6acab13b
      Jacob Keller 提交于
      When implementing launch time support in the igb and igc drivers, the
      skb->tstamp value is assumed to be a s64, but it's declared as a ktime_t
      value.
      
      Although ktime_t is typedef'd to s64 it wasn't always, and the kernel
      provides accessors for ktime_t values.
      
      Use the ktime_to_timespec64 and ktime_set accessors instead of directly
      assuming that the variable is always an s64.
      
      This improves portability if the code is ever moved to another kernel
      version, or if the definition of ktime_t ever changes again in the
      future.
