      Paolo Bonzini authored
      29ecd660 ("KVM: x86: avoid uninitialized variable warning",
      2015-09-06) introduced a not-so-subtle problem, which probably
      escaped review because it was not part of the patch context.
      
      Before the patch, leaf was always equal to iterator.level.  After,
      it is equal to iterator.level - 1 in the call to is_shadow_zero_bits_set,
      and when is_shadow_zero_bits_set does another "-1" the check on
      reserved bits becomes incorrect.  Using "iterator.level" in the call
      fixes this call trace:

      Intel CPUID on AMD host or vice versa is a weird case, but it can
      happen.  Handle it by checking the host CPU vendor instead of the
      guest's in reset_tdp_shadow_zero_bits_mask.  For speed, the
      check uses the fact that Intel EPT has an X (executable) bit while
      AMD NPT has NX.

      kvm_set_cr0 may want to call kvm_zap_gfn_range and thus access the
      memslots array (SRCU protected).  Using a mini SRCU critical section
      is ugly, and adding it to kvm_arch_vcpu_create doesn't work because
      the VMX vcpu_create callback calls synchronize_srcu.

      ====================
      Phy, mdiobus, and netdev struct device fixes
      
      The third version of this series fixes the build error which David
      identified, and drops the broken changes for the Cavium Thunger BGX
      ethernet driver as this driver requires some complex changes to
      resolve the leakage - and this is best done by people who can test
      the driver.
      
      Compared to v2, the only patch which has changed is patch 6
        "net: fix phy refcounting in a bunch of drivers"
      
      I _think_ I've been able to build-test all the drivers touched by
      that patch to some degree now, though several of them needed the
      Kconfig hacked to allow it (not all had || COMPILE_TEST clause on
      their dependencies.)
      
      Previous cover letters below:
      
      This is the second version of the series, with the comments David had
      on the first patch fixed up.  Original series description with updated
      diffstat below.
      
      While looking at the DSA code, I noticed we have a
      of_find_net_device_by_node(), and it looks like users of that are
      similarly buggy - it looks like net/dsa/dsa.c is the only user.  Fix
      that too.
      
      Hi,
      
      While looking at the phy code, I identified a number of weaknesses
      where refcounting on device structures was being leaked, where
      modules could be removed while in-use, and where the fixed-phy could
      end up having unintended consequences caused by incorrect calls to
      fixed_phy_update_state().
      
      This patch series resolves those issues, some of which were discovered
      with testing on an Armada 388 board.  Not all patches are fully tested,
      particularly the one which touches several network drivers.
      
      When resolving the struct device refcounting problems, several different
      solutions were considered before settling on the implementation here -
      one of the considerations was to avoid touching many network drivers.
      The solution here is:
      
      	phy_attach*() - takes a refcount
      	phy_detach*() - drops the phy_attach refcount
      
      Provided drivers always attach and detach their phys, which they should
      already be doing, this should change nothing, even if they leak a refcount.
      
      	of_phy_find_device() and of_* functions which use that take
      	a refcount.  Arrange for this refcount to be dropped once
      	the phy is attached.
      
      This is the reason why the previous change is important - we can't drop
      this refcount taken by of_phy_find_device() until something else holds
      a reference on the device.  This resolves the leaked refcount caused by
      using of_phy_connect() or of_phy_attach().
      
      Even without the above changes, these drivers are leaking by calling
      of_phy_find_device().  These drivers are addressed by adding the
      appropriate release of that refcount.
      
      The mdiobus code also suffered from the same kind of leak, but thankfully
      this only happened in one place - the mdio-mux code.
      
      I also found that the try_module_get() in the phy layer code was utterly
      useless: phydev->dev.driver was guaranteed to always be NULL, so
      try_module_get() was always being called with a NULL argument.  I proved
      this with my SFP code, which declares its own MDIO bus - the module use
      count was never incremented irrespective of how I set the MDIO bus up.
      This allowed the MDIO bus code to be removed from the kernel while there
      were still PHYs attached to it.
      
      One other bug was discovered: while using in-band-status with mvneta, it
      was found that if a real phy is attached with in-band-status enabled,
      and another ethernet interface is using the fixed-phy infrastructure, the
      interface using the fixed-phy infrastructure is configured according to
      the other interface using the in-band-status - which is caused by the
      fixed-phy code not verifying that the phy_device passed in is actually
      a fixed-phy device, rather than a real MDIO phy.
      
      Lastly, having mdio_bus reversing phy_device_register() internals seems
      like a layering violation - it's trivial to move that code to the phy
      device layer.

      net: fix phy refcounting in a bunch of drivers · 04d53b20
      Russell King authored
      of_phy_find_device() increments the phy struct device refcount, which
      we need to properly balance.  Add code to network drivers using this
      function to ensure that the struct device refcount is correctly
      balanced.
      
      For xgene, looking back in the history, we should be able to use
      of_phy_connect() with a zero flags argument for the DT case as this is
      how the driver used to operate prior to de7b5b3d ("net: eth: xgene:
      change APM X-Gene SoC platform ethernet to support ACPI").
      
      This leaves the Cavium Thunder BGX unfixed; fixing this driver is a
      complicated task, one which the maintainers need to be involved with.

      of_mdio: fix MDIO phy device refcounting · f018ae7a
      Russell King authored
      bus_find_device() is defined as:
      
       * This is similar to the bus_for_each_dev() function above, but it
       * returns a reference to a device that is 'found' for later use, as
       * determined by the @match callback.
      
      and it does indeed return a reference-counted pointer to the device:
      
              while ((dev = next_device(&i)))
                      if (match(dev, data) && get_device(dev))
                                              ^^^^^^^^^^^^^^^
                              break;
              klist_iter_exit(&i);
              return dev;
      
      What that means is that when we're done with the struct device, we must
      drop that reference.  Neither of_phy_connect() nor of_phy_attach() did
      this when phy_connect_direct() or phy_attach_direct() failed.
      
      With our previous patch, phy_connect_direct() and phy_attach_direct()
      take a new refcount on the phy device when successful, so we can drop
      our local reference immediatley after these functions, whether or not
      they succeeded.

      phy: fix mdiobus module safety · 3e3aaf64
      Russell King authored
      Re-implement the mdiobus module refcounting to ensure that we actually
      ensure that the mdiobus module code does not go away while we might call
      into it.
      
      The old scheme using bus->dev.driver was buggy, because bus->dev is a
      class device which never has a struct device_driver associated with it,
      and hence the associated code trying to obtain a refcount did nothing
      useful.
      
      Instead, take the approach that other subsystems do: pass the module
      when calling mdiobus_register(), and record that in the mii_bus struct.
      When we need to increment the module use count in the phy code, use
      this stored pointer.  When the phy is deteched, drop the module
      refcount, remembering that the phy device might go away at that point.
      
      This doesn't stop the mii_bus going away while there are in-use phys -
      it merely stops the underlying code vanishing.

      Russell King authored
      Current users of of_mdio_find_bus() leak a struct device refcount, as
      they fail to clean up the reference obtained inside class_find_device().
      
      Fix the DSA code to properly refcount the returned MDIO bus by:
      1. taking a reference on the struct device whenever we assign it to
         pd->chip[x].host_dev.
      2. dropping the reference when we overwrite the existing reference.
      3. dropping the reference when we free the data structure.
      4. dropping the initial reference we obtained after setting up the
         platform data structure, or on failure.
      
      In step 2 above, where we obtain a new MDIO bus, there is no need to
      take a reference on it as we would only have to drop it immediately
      after assignment again, iow:
      
      	put_device(cd->host_dev);	/* drop original assignment ref */
      	cd->host_dev = get_device(&mdio_bus_switch->dev); /* get our ref */

      Currently error log messages in ip6_tnl_err are printed at 'warn'

      any messages. These log messages don't provide any information that
      couldn't be deduced with networking tools. Also it can be annoying
      to have one end of the tunnel go down and have the logs fill with
      pointless messages such as "Path to destination invalid or inactive!".
      
      This patch reduces the log level of these messages to 'dbg' level to
      bring the visible behaviour into line with other tunnel types.

      The idle-states bindings mandate that the entry-method string
      in the idle-states node must be "psci" for ARM v8 64-bit systems,
      but the examples in the bindings report a wrong entry-method string.
      Owing to this typo, some dts in the kernel wrongly defined the
      entry-method property, since they likely cut and pasted the example
      definition without paying attention to the bindings definitions.
      
      This patch fixes the typo in the DT idle states bindings examples and
      respective dts in the kernel so that the bindings and related dts
      files are made compliant.
