   - initialize net->notrefcnt_tracker earlier

   - devlink: fix netdev notifier chain corruption

   - nfp: make sure mbox accesses in IPsec code are atomic

   - ice: fix check for weight and priority of a scheduling node

  Previous releases - regressions:

   - ice: xsk: fix cleaning of XDP_TX frame, prevent inf loop

   - igb: fix I2C bit banging config with external thermal sensor

  Previous releases - always broken:

   - sched: tcindex: update imperfect hash filters respecting rcu

Cited commit changed devlink to register its netdev notifier block on
the global netdev notifier chain instead of on the per network namespace
one.

However, when changing the network namespace of the devlink instance,
devlink still tries to unregister its notifier block from the chain of
the old namespace and register it on the chain of the new namespace.
This results in corruption of the notifier chains, as the same notifier
block is registered on two different chains: The global one and the per
network namespace one. In turn, this causes other problems such as the
inability to dismantle namespaces due to netdev reference count issues.

Fix by preventing devlink from moving its notifier block between
namespaces.

Reproducer:

 # echo "10 1" > /sys/bus/netdevsim/new_device
 # ip netns add test123
 # devlink dev reload netdevsim/netdevsim10 netns test123
 # ip netns del test123

Commit a97f8783 ("igb: unbreak I2C bit-banging on i350") introduced
code to change I2C settings to bit banging unconditionally.

However, this patch introduced a regression:  On an Intel S2600CWR
Server Board with three NICs:

- 1x dual-port copper
  Intel I350 Gigabit Network Connection [8086:1521] (rev 01)
  fw 1.63, 0x80000dda

- 2x quad-port SFP+ with copper SFP Avago ABCU-5700RZ
  Intel I350 Gigabit Fiber Network Connection [8086:1522] (rev 01)
  fw 1.52.0

the SFP NICs no longer get link at all.  Reverting commit a97f8783
or switching to the Intel out-of-tree driver both fix the problem.

Per the igb out-of-tree driver, I2C bit banging on i350 depends on
support for an external thermal sensor (ETS).  However, commit
a97f8783 added bit banging unconditionally.  Additionally, the
out-of-tree driver always calls init_thermal_sensor_thresh on probe,
while our driver only calls init_thermal_sensor_thresh only in
igb_reset(), and only if an ETS is present, ignoring the internal
thermal sensor.  The affected SFPs don't provide an ETS.  Per Intel,
the behaviour is a result of i350 firmware requirements.

This patch fixes the problem by aligning the behaviour to the
out-of-tree driver:

- split igb_init_i2c() into two functions:
  - igb_init_i2c() only performs the basic I2C initialization.
  - igb_set_i2c_bb() makes sure that E1000_CTRL_I2C_ENA is set
    and enables bit-banging.

- igb_probe() only calls igb_set_i2c_bb() if an ETS is present.

- igb_probe() calls init_thermal_sensor_thresh() unconditionally.

- igb_reset() aligns its behaviour to igb_probe(), i. e., call
  igb_set_i2c_bb() if an ETS is present and call
  init_thermal_sensor_thresh() unconditionally.

This fixes a regression in mediation of getattr when old policy built
under an older ABI is loaded and mapped to internal permissions.

The regression does not occur for all getattr permission requests,
only appearing if state zero is the final state in the permission
lookup.  This is because despite the first state (index 0) being
guaranteed to not have permissions in both newer and older permission
formats, it may have to carry permissions that were not mediated as
part of an older policy. These backward compat permissions are
mapped here to avoid special casing the mediation code paths.

Since the mapping code already takes into account backwards compat
permission from older formats it can be applied to state 0 to fix
the regression.

The commit 1796f808 ("HID: i2c-hid: acpi: Stop setting wakeup_capable")
changed the policy such that I2C touchpads may be able to wake up the
system by default if the system is configured as such.

However for some devices there is a bug, that is causing the touchpad to
instantly wake up the device again once it gets deactivated. The root cause
is still under investigation (see Link tag).

To workaround this problem for the time being, introduce a quirk for this
model that will prevent the wakeup capability for being set for GPIO 16.

lianhui reports that when MPLS fails to register the sysctl table
under new location (during device rename) the old pointers won't
get overwritten and may be freed again (double free).

Handle this gracefully. The best option would be unregistering
the MPLS from the device completely on failure, but unfortunately
mpls_ifdown() can fail. So failing fully is also unreliable.

Another option is to register the new table first then only
remove old one if the new one succeeds. That requires more
code, changes order of notifications and two tables may be
visible at the same time.

sysctl point is not used in the rest of the code - set to NULL
on failures and skip unregister if already NULL.

Recently I encountered one case where I cannot increase the MTU size
directly from 1500 to a much bigger value with XDP enabled if the
server is equipped with IXGBE card, which happened on thousands of
servers in production environment. After applying the current patch,
we can set the maximum MTU size to 3K.

This patch follows the behavior of changing MTU as i40e/ice does.

Pull kvm fixes from Paolo Bonzini:
 "Certain AMD processors are vulnerable to a cross-thread return address
  predictions bug. When running in SMT mode and one of the sibling
  threads transitions out of C0 state, the other thread gets access to
  twice as many entries in the RSB, but unfortunately the predictions of
  the now-halted logical processor are not purged. Therefore, the
  executing processor could speculatively execute from locations that
  the now-halted processor had trained the RSB on.

  The Spectre v2 mitigations cover the Linux kernel, as it fills the RSB
  when context switching to the idle thread. However, KVM allows a VMM
  to prevent exiting guest mode when transitioning out of C0 using the
  KVM_CAP_X86_DISABLE_EXITS capability can be used by a VMM to change
  this behavior. To mitigate the cross-thread return address predictions
  bug, a VMM must not be allowed to override the default behavior to
  intercept C0 transitions.

  These patches introduce a KVM module parameter that, if set, will
  prevent the user from disabling the HLT, MWAIT and CSTATE exits"

So far changing the period by just setting new period values while
running did not work.

The order as indicated by the publicly available reference manual of the i.MX8MP [1]
indicates a sequence:

 * initiate the programming sequence
 * set the values for PPS period and start time
 * start the pulse train generation.

This is currently not used in dwmac5_flex_pps_config(), which instead does:

 * initiate the programming sequence and immediately start the pulse train generation
 * set the values for PPS period and start time

This caused the period values written not to take effect until the FlexPPS output was
disabled and re-enabled again.

This patch fix the order and allows the period to be set immediately.

There was a problem reported to us where the addition of a VF with an IPv6
address ending with a particular sequence would cause the parent device on
the PF to no longer be able to respond to neighbor discovery packets.

In this case, we had an ovs-bridge device living on top of a VLAN, which
was on top of a PF, and it would not be able to talk anymore (the neighbor
entry would expire and couldn't be restored).

The root cause of the issue is that if the PF is asked to be in IFF_PROMISC
mode (promiscuous mode) and it had an ipv6 address that needed the
33:33:ff:00:00:04 multicast address to work, then when the VF was added
with the need for the same multicast address, the VF would steal all the
traffic destined for that address.

The ice driver didn't auto-subscribe a request of IFF_PROMISC to the
"multicast replication from other port's traffic" meaning that it won't get
for instance, packets with an exact destination in the VF, as above.

The VF's IPv6 address, which adds a "perfect filter" for 33:33:ff:00:00:04,
results in no packets for that multicast address making it to the PF (which
is in promisc but NOT "multicast replication").

The fix is to enable "multicast promiscuous" whenever the driver is asked
to enable IFF_PROMISC, and make sure to disable it when appropriate.
