There is a race conditions between packet_notifier and packet_bind{_spkt}.
It happens if packet_notifier(NETDEV_UNREGISTER) executes between the
time packet_bind{_spkt} takes a reference on the new netdevice and the
time packet_do_bind sets po->ifindex.
In this case the notification can be missed.
If this happens during a dev_change_net_namespace this can result in the
netdevice to be moved to the new namespace while the packet_sock in the
old namespace still holds a reference on it. When the netdevice is later
deleted in the new namespace the deletion hangs since the packet_sock
is not found in the new namespace' &net->packet.sklist.
It can be reproduced with the script below.
This patch makes packet_do_bind check again for the presence of the
netdevice in the packet_sock's namespace after the synchronize_net
in unregister_prot_hook.
More in general it also uses the rcu lock for the duration of the bind
to stop dev_change_net_namespace/rollback_registered_many from
going past the synchronize_net following unlist_netdevice, so that
no NETDEV_UNREGISTER notifications can happen on the new netdevice
while the bind is executing. In order to do this some code from
packet_bind{_spkt} is consolidated into packet_do_dev.

The DSA documentation specifies that each port must be capable of
forwarding frames to the CPU port. The last changes on bridging support
for the mv88e6xxx driver broke this requirement for non-bridged ports.
So as for the bridged ports, reserve a few VLANs (4000+) in the switch
to isolate ports that have not been bridged yet.
By default, a port will be isolated with the CPU and DSA ports. When the
port joins a bridge, it will leave its reserved port. When it is removed
from a bridge, it will join its reserved VLAN again.

We have a timed release of a forcewake when using
I915_READ/WRITE macros. wait_for() macro will go to quite
long sleep if the first read doesn't satisfy the condition for
successful exit. With these two interacting, it is possible that
we lose the forcewake during the wait_for() and the subsequent read
will reaquire forcewake.
Further experiments with skl shows that when we lose forcewake,
we lose the reset request we submitted. So reset request register
is not power context saved.
Grab forcewakes for all engines before starting the reset/request
dance so that all requests stay valid for the duration of reset
requisition across all the engines.
v2: Add comment on power well sleeps. Wrap the reset handling
under forcewake instead of just reset requests (Chris)

[Rewrite to use vmcs_set_secondary_exec_control. - Paolo]
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
The reason is in above commit vmx_cpuid_update calls vmx_secondary_exec_control,
in which currently SECONDARY_EXEC_ENABLE_PML bit is cleared unconditionally (as
PML is enabled in creating vcpu). Therefore if vcpu_cpuid_update is called after
vcpu is created, PML will be disabled unexpectedly while log-dirty code still
thinks PML is used.
Fix this by clearing SECONDARY_EXEC_ENABLE_PML in vmx_secondary_exec_control
only when PML is not supported or not enabled (!enable_pml). This is more
reasonable as PML is currently either always enabled or disabled. With this
explicit updating SECONDARY_EXEC_ENABLE_PML in vmx_enable{disable}_pml is not
needed so also rename vmx_enable{disable}_pml to vmx_create{destroy}_pml_buffer.

When connecting the Cintiq Companion 2 as an external tablet (i.e., using
it in "hybrid" mode) it has been seen to cause the kernel of the machine
it is connected to to Oops. The cause has been traced to us attempting to
switch the tablet's mode prior to actually starting HID device (resulting
in the eventual dereference of the uninitialized control URB).
Commit 3b164a0 moved the mode switch from occuring post-start to occurring
pre-start. The change was not seen to cause issues largely due to the fact
that most devices mode switch with 'hid_hw_raw_request' (which is safe to
call prior to start) rather than 'hid_hw_request'.
Moving the call back to its original location resolves the issue, but
causes some touch-only Bamboo tablets (e.g. 056a:00d0) to stop working.
The affected tablets require us to perform a mode switch on their
vestigial pen interface prior ignoring with -ENODEV, meaning that the
code which is responsible for doing the ignoring has to move as well.

Two major components to this update.
1/ the clustered-raid1 support from SUSE is nearly
complete. There are a few outstanding issues being
worked on. Maybe half a dozen patches will bring
this to a usable state.
2/ The first stage of journalled-raid5 support from
Facebook makes an appearance. With a journal
device configured (typically NVRAM or SSD), the
"RAID5 write hole" should be closed - a crash
during degraded operations cannot result in data
corruption.
The next stage will be to use the journal as a
write-behind cache so that latency can be reduced
and in some cases throughput increased by
performing more full-stripe writes.

In tracefs' start_creating(), we pin the file system to safely access
its root. When we failed to create a file, we unpin the file system via
failed_creating() to release the mount count and eventually the reference
of the singleton vfsmount.
However, when we run into an error during lookup_one_len() when still
in start_creating(), we only release the parent's mutex but not so the
reference on the mount.
F.e., in securityfs_create_file(), after doing simple_pin_fs() when
lookup_one_len() fails there, we infact do simple_release_fs(). This
seems necessary here as well.
Same issue seen in debugfs due to 190afd81e4 ("debugfs: split the
beginning and the end of __create_file() off"), which seemed to got
carried over into tracefs, too. Noticed during code review.

MODE_MF_SI is 9. We should be testing bit 9 instead of AND 0x9.

We check if "p_hwfn" is NULL and then dereference it in the error
handling code. I read the code and it isn't NULL so let's remove the
check.

When receiving a connect response we should make sure that the DCID is
within the valid range and that we don't already have another channel
allocated for the same DCID.

The 'dyn_end' value is also a valid CID so it should be included in

The core spec defines specific response codes for situations when the
received CID is incorrect. Add the defines for these and return them
as appropriate from the LE Connect Request handler function.

The white list commands might not be implemented if the controller does
not actually support the white list. So check the supported commands
first before issuing these commands. Not supporting the white list is
the same as supporting a white list with zero size.

When a listen socket enqueues a connection for userspace to accept(),
the sk->sk_data_ready() callback should be invoked. In-kernel socket
users rely on this callback to detect when incoming connections are
available.
Currently the sk->sk_state_change() callback is invoked by
vmci_transport.c. This happens to work for userspace applications since
sk->sk_state_change = sock_def_wakeup() and sk->sk_data_ready =
sock_def_readable() both wake up the accept() waiter. In-kernel socket
users, on the other hand, fail to detect incoming connections.

In tun_dst_unclone() the return value of skb_metadata_dst() is checked
for being NULL after it is dereferenced. Fix this by moving the
dereference after the NULL check.
