      cxgb4vf: Enter debugging mode if FW is inaccessible · 4a8acef7
      Arjun Vynipadath authored
      If we are not able to reach firmware, enter debugging mode that will
      help us to get adapter logs.

      cxgb4: Enable outer UDP checksum offload for T6 · 64f40cdd
      Arjun Vynipadath authored
      T6 adapters support outer UDP checksum offload for
      encapsulated packets, hence enabling netdev feature flag
      NETIF_F_GSO_UDP_TUNNEL_CSUM.

      cxgb4/cxgb4vf: Fix up netdev->hw_features · 012475e3
      Arjun Vynipadath authored
      GRO is done by cxgb4/cxgb4vf. Hence set NETIF_F_GRO flag for
      both cxgb4/cxgb4vf.
      Cleaned up VLAN netdev features in cxgb4vf. Also fixed
      NETIF_F_HIGHDMA being set unconditionally for vlan netdev
      features.

      net: sched: act_csum: Fix csum calc for tagged packets · 2ecba2d1
      Eli Britstein authored
      The csum calculation is different for IPv4/6. For VLAN packets,
      tc_skb_protocol returns the VLAN protocol rather than the packet's one
      (e.g. IPv4/6), so csum is not calculated. Furthermore, VLAN may not be
      stripped so csum is not calculated in this case too. Calculate the
      csum for those cases.

      net: hns: use struct_size() in devm_kzalloc() · d89ea4ac
      Gustavo A. R. Silva authored
      One of the more common cases of allocation size calculations is finding
      the size of a structure that has a zero-sized array at the end, along
      with memory for some number of elements for that array. For example:
      
      struct foo {
          int stuff;
          struct boo entry[];
      };
      
      instance = devm_kzalloc(dev, sizeof(struct foo) + sizeof(struct boo) * count, GFP_KERNEL);
      
      Instead of leaving these open-coded and prone to type mistakes, we can
      now use the new struct_size() helper:
      
      instance = devm_kzalloc(dev, struct_size(instance, entry, count), GFP_KERNEL);
      
      This code was detected with the help of Coccinelle.

      ====================
      net: phy: marvell10g: Clean .get_features by using C45 helpers
      
      Recent work on C45 helpers by Heiner made the
      genphy_c45_pma_read_abilities function generic enough to use as a
      default .get_featutes implementation.
      
      This series removes the remaining redundant code in
      mv3310_get_features(), and makes the 2110 PHY use
      genphy_c45_pma_read_abilities() directly, since it doesn't have the
      issue with the wrong abilities being reported.

      net: phy: marvell10g: Use the generic C45 helper to read the 2110 features · 41e2a99f
      Maxime Chevallier authored
      Contrary to the 3310, the 2110 PHY correctly reports it's 2.5G/5G
      abilities. We can therefore use the genphy_c45_pma_read_abilities helper
      to build the list of features.

      Maxime Chevallier authored
      The genphy_c45_pma_read_abilities helper now sets the Autoneg ability
      in phydev->supported according to what the AN MMD reports.
      
      We therefore don't need to manually do that in mv3310_get_features().

      net: sched: act_tunnel_key: fix metadata handling · 87750d17
      Vlad Buslov authored
      Tunnel key action params->tcft_enc_metadata is only set when action is
      TCA_TUNNEL_KEY_ACT_SET. However, metadata pointer is incorrectly
      dereferenced during tunnel key init and release without verifying that
      action is if correct type, which causes NULL pointer dereference. Metadata
      tunnel dst_cache is also leaked on action overwrite.
      
      Fix metadata handling:
      - Verify that metadata pointer is not NULL before dereferencing it in
        tunnel_key_init error handling code.
      - Move dst_cache destroy code into tunnel_key_release_params() function
        that is called in both action overwrite and release cases (fixes resource
        leak) and verifies that actions has correct type before dereferencing
        metadata pointer (fixes NULL pointer dereference).
