      net sched: fix encoding to use real length · 28a10c42
      Jamal Hadi Salim 提交于
      Encoding of the metadata was using the padded length as opposed to
      the real length of the data which is a bug per specification.
      This has not been an issue todate because all metadatum specified
      so far has been 32 bit where aligned and data length are the same width.
      This also includes a bug fix for validating the length of a u16 field.
      But since there is no metadata of size u16 yes we are fine to include it
      here.
      
      While at it get rid of magic numbers.

      qed: FLR of active VFs might lead to FW assert · 4870e704
      Yuval Mintz 提交于
      Driver never bothered marking the VF's vport with the VF's sw_fid.
      As a result, FLR flows are not going to clean those vports.
      
      If the vport was active when FLRed, re-activating it would lead
      to a FW assertion.

      net: ip_finish_output_gso: Allow fragmenting segments of tunneled skbs if their DF is unset · c0451fe1
      Shmulik Ladkani 提交于
      In b8247f09,
      
         "net: ip_finish_output_gso: If skb_gso_network_seglen exceeds MTU, allow segmentation for local udp tunneled skbs"
      
      gso skbs arriving from an ingress interface that go through UDP
      tunneling, are allowed to be fragmented if the resulting encapulated
      segments exceed the dst mtu of the egress interface.
      
      This aligned the behavior of gso skbs to non-gso skbs going through udp
      encapsulation path.
      
      However the non-gso vs gso anomaly is present also in the following
      cases of a GRE tunnel:
       - ip_gre in collect_md mode, where TUNNEL_DONT_FRAGMENT is not set
         (e.g. OvS vport-gre with df_default=false)
       - ip_gre in nopmtudisc mode, where IFLA_GRE_IGNORE_DF is set
      
      In both of the above cases, the non-gso skbs get fragmented, whereas the
      gso skbs (having skb_gso_network_seglen that exceeds dst mtu) get dropped,
      as they don't go through the segment+fragment code path.
      
      Fix: Setting IPSKB_FRAG_SEGS if the tunnel specified IP_DF bit is NOT set.
      
      Tunnels that do set IP_DF, will not go to fragmentation of segments.
      This preserves behavior of ip_gre in (the default) pmtudisc mode.
      
      Fixes: b8247f09 ("net: ip_finish_output_gso: If skb_gso_network_seglen exceeds MTU, allow segmentation for local udp tunneled skbs")
