      afs: Fix server record deletion · 66062592
      David Howells authored
      AFS server records get removed from the net->fs_servers tree when
      they're deleted, but not from the net->fs_addresses{4,6} lists, which
      can lead to an oops in afs_find_server() when a server record has been
      removed, for instance during rmmod.
      Fix this by deleting the record from the by-address lists before posting
      it for RCU destruction.
      The reason this hasn't been noticed before is that the fileserver keeps
      probing the local cache manager, thereby keeping the service record
      alive, so the oops would only happen when a fileserver eventually gets
      bored and stops pinging or if the module gets rmmod'd and a call comes
      in from the fileserver during the window between the server records
      being destroyed and the socket being closed.
      The oops looks something like:
        BUG: unable to handle kernel NULL pointer dereference at 000000000000001c
        Workqueue: kafsd afs_process_async_call [kafs]

      tun: do not compute the rxhash, if not needed · cf1a1e07

      Currently, the tun driver, in absence of an eBPF steering program,
      always compute the rxhash in its rx path, even when such value
      is later unused due to additional checks (
      This changeset moves the all the related checks just before the
      __skb_get_hash_symmetric(), so that the latter is no more computed
      when unneeded.
      Also replace an unneeded RCU section with rcu_access_pointer().

      lan78xx: Read LED states from Device Tree · 1827b067
      Phil Elwell authored
      Add support for DT property "microchip,led-modes", a vector of zero
      to four cells (u32s) in the range 0-15, each of which sets the mode
      for one of the LEDs. Some possible values are:
          0=link/activity          1=link1000/activity
          2=link100/activity       3=link10/activity
          4=link100/1000/activity  5=link10/1000/activity
          6=link10/100/activity    14=off    15=on
      These values are given symbolic constants in a dt-bindings header.
      Also use the presence of the DT property to indicate that the
      LEDs should be enabled - necessary in the event that no valid OTP
      or EEPROM is available.

      qed* : Use trust mode to override forced MAC
      This patchset adds a support to override forced MAC (MAC set by PF for a VF)

      First patch adds a real change to use .ndo_set_vf_trust to override forced MAC
      and allow user to change VFs from VF interface itself.
      Second patch takes care of a corner case, where MAC change from VF won't
      take effect when VF interface is down, by introducing a new TLV
      (a way to send message from VF to PF) to give a hint to PF to update
      its bulletin board.
