When the bcmgenet_mii_config() code was refactored it was missed
that the LED control for the MoCA interface got overwritten by
the port_ctrl value. Its previous programming is restored here.

Data passed to user-space with a (SOL_UDP, UDP_GRO) cmsg carries an
int (see udp_cmsg_recv), not a u16 value, as strace confirms:
recvmsg(8, {msg_name=...,
msg_iov=[{iov_base="\0\0..."..., iov_len=96000}],
msg_iovlen=1,
msg_control=[{cmsg_len=20, <-- sizeof(cmsghdr) + 4
cmsg_level=SOL_UDP,
cmsg_type=0x68}], <-- UDP_GRO
msg_controllen=24,
msg_flags=0}, 0) = 11200
Interpreting the data as an u16 value won't work on big-endian platforms.
Since it is too late to back out of this API decision [1], fix the test.

On default driver load device gets configured with unexpected
higher interrupt coalescing values instead of default expected
values as memory allocated from krealloc() is not supposed to
be zeroed out and may contain garbage values.
Fix this by allocating the memory of required size first with
kcalloc() and then use krealloc() to resize and preserve the
contents across down/up of the interface.

We will find that the error is HTTP 400 error, which is a serious

Consider the following scenarios:
CPU0 CPU1
buf_desc->used = 0;
cmpxchg(buf_desc->used, 0, 1)
deal_with(buf_desc)
memset(buf_desc->cpu_addr,0);
This will cause the data received by a victim connection to be cleared,
thus triggering an HTTP 400 error in the server.
This patch exchange the order between clear used and memset, add
barrier to ensure memory consistency.

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 a97f8783a9 ("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 a97f8783a9
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
a97f8783a9 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.

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.

v3: Fix vmw_user_bo_lookup which was also dropping the gem reference
before the kernel was done with buffer depending on userspace doing
the right thing. Same bug, different spot.
It is possible for userspace to predict the next buffer handle and
to destroy the buffer while it's still used by the kernel. Delay
dropping the internal reference on the buffers until kernel is done
with them.
Instead of immediately dropping the gem reference in vmw_user_bo_lookup
and vmw_gem_object_create_with_handle let the callers decide when they're
ready give the control back to userspace.
Also fixes the second usage of vmw_gem_object_create_with_handle in
vmwgfx_surface.c which wasn't grabbing an explicit reference
to the gem object which could have been destroyed by the userspace
on the owning surface at any point.

After the double free the vmw_gem_object_create_with_handle was

Fix the entire path by relaying on ttm_bo_init_reserved to delete the

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.
References:
[1] commit 23b44513c3 ("ice: allow 3k MTU for XDP")
[2] commit 0c8493d90b ("i40e: add XDP support for pass and drop actions")
Fixes: fabf1bce10 ("ixgbe: Prevent unsupported configurations with XDP")

cpufreq: qcom-hw: Add missing null pointer check
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.
