      efi-pstore: Fix write/erase id tracking · c10e8031
      Kees Cook authored
      
      
      Prior to the pstore interface refactoring, the "id" generated during
      a backend pstore_write() was only retained by the internal pstore
      inode tracking list. Additionally the "part" was ignored, so EFI
      would encode this in the id. This corrects the misunderstandings
      and correctly sets "id" during pstore_write(), and uses "part"
      directly during pstore_erase().

         2) Don't delete conntrack helpers while they are still in use, from

            Bruijn.

            cannot guarantee that we hold the NFNL_SUBSYS_NFTABLES lock. From
            Liping Zhang.

         6) smsc95xx devices can't handle IPV6 checksums fully, so don't
            advertise support for offloading them. From Nisar Sayed.
      
         7) Fix out-of-bounds access in __ip6_append_data(), from Eric
            Dumazet.

            from Alexey Khoroshilov.
      
         9) arp_target[] in bond_check_params() is used uninitialized. This
            got changes from a global static to a local variable, which is how
            this mistake happened. Fix from Jarod Wilson.

      bonding: fix randomly populated arp target array · 72ccc471
      Jarod Wilson authored
      In commit dc9c4d0f, the arp_target array moved from a static global
      to a local variable. By the nature of static globals, the array used to
      be initialized to all 0. At present, it's full of random data, which
      that gets interpreted as arp_target values, when none have actually been
      specified. Systems end up booting with spew along these lines:

      None of these were actually specified as ARP targets, and the driver does
      seem to clean up the mess okay, but it's rather noisy and confusing, leaks
      values to userspace, and the 255.255.255.255 spew shows up even when debug
      prints are disabled.
      
      The fix: just zero out arp_target at init time.
      
      While we're in here, init arp_all_targets_value in the right place.

      net: Make IP alignment calulations clearer. · e4eda884

      The assignmnet:
      
      	ip_align = strict ? 2 : NET_IP_ALIGN;
      
      in compare_pkt_ptr_alignment() trips up Coverity because we can only
      get to this code when strict is true, therefore ip_align will always
      be 2 regardless of NET_IP_ALIGN's value.
      
      So just assign directly to '2' and explain the situation in the
      comment above.

      bonding: fix accounting of active ports in 3ad · 751da2a6
      Jarod Wilson authored
      As of 7bb11dc9 and 0622cab0, bond slaves in a 3ad bond are not
      removed from the aggregator when they are down, and the active slave count
      is NOT equal to number of ports in the aggregator, but rather the number
      of ports in the aggregator that are still enabled. The sysfs spew for
      bonding_show_ad_num_ports() has a comment that says "Show number of active
      802.3ad ports.", but it's currently showing total number of ports, both
      active and inactive. Remedy it by using the same logic introduced in
      0622cab0
      
       in __bond_3ad_get_active_agg_info(), so sysfs, procfs and
      netlink all report the number of active ports. Note that this means that
      IFLA_BOND_AD_INFO_NUM_PORTS really means NUM_ACTIVE_PORTS instead of
      NUM_PORTS, and thus perhaps should be renamed for clarity.
      
      Lightly tested on a dual i40e lacp bond, simulating link downs with an ip
      link set dev <slave2> down, was able to produce the state where I could
      see both in the same aggregator, but a number of ports count of 1.

      If dma mask checks fail in atl2_probe(), it breaks off initialization,

      make error code setup unified.
