Since commit 9cc4b7cb86cb ("brcmfmac: Make skb header writable
before use") the headroom usage has been fixed. However, the
driver was keeping statistics that got lost. So reworking the
code so we get those driver statistics back for debugging.

When user adds a virtual interface driver will set the
bss_type to the iface_type given by the user. When
supplicant is started on the same interface, a call to
change_virtual_intf will be triggered if if_type is not
NL80211_IFTYPE_STATION. Here driver should not update
it's bss_type, because bss_type is intended to indicate
the original iface_type and changing the same will defeat
the purpose of creating this interface.

Sometimes DMI fields may be invalid and so can't give useful vendor,
product or board info, such as "Type2 - Board Manufacturer" or
"Type1 - TBD by OEM". Including such invalid DMI fileds may create silly
card long name. So this patch creates a black list of invalid strings.
And if a DMI field contains any string in this list, it will be excluded
from the card long name.

GPD Win requires jd_mode=3 and the inverted flag for making the jack
detection working. Unfortunately, the BIOS doesn't give a nice way to
match with DMI strings, and the only working way so far is to match
with the board vendor/name/version/date to some known patterns.
Hopefully other vendors won't do such a stupid setup, too...
Thanks to Hans de Goede for the DMI matching suggestion.

Many subsystems will not use refcount_t unless there is a way to build the
kernel so that there is no regression in speed compared to atomic_t. This
adds CONFIG_REFCOUNT_FULL to enable the full refcount_t implementation
which has the validation but is slightly slower. When not enabled,
refcount_t uses the basic unchecked atomic_t routines, which results in
no code changes compared to just using atomic_t directly.

The bug was triggered when do suspend/resuming continuously
on Dell XPS L322X/0PJHXN version 9333 (2013) with kernel
4.12.0-041200rc4-generic. But can't reproduce on DELL
E5440 + AR9300 PCIE chips.
The warning is caused by accessing invalid pointer sc->rng_task.
sc->rng_task is not be cleared after kthread_stop(sc->rng_task)
be called in ath9k_rng_stop(). Because the kthread is stopped
before ath9k_rng_kthread() be scheduled.
So set sc->rng_task to null after kthread_stop(sc->rng_task) to
resolve this issue.

One scenario that could lead to UAF is two threads writing
simultaneously to the "tx99" debug file. One of them would
set the "start" value to true and follow to ath9k_tx99_init().
Inside the function it would set the sc->tx99_state to true
after allocating sc->tx99skb. Then, the other thread would
execute write_file_tx99() and call ath9k_tx99_deinit().
sc->tx99_state would be freed. After that, the first thread
would continue inside ath9k_tx99_init() and call
r = ath9k_tx99_send(sc, sc->tx99_skb, &txctl);
that would make use of the freed sc->tx99_skb memory.

SandyBridge HDMI codecs, but it has a potential problem of the nested

We can deadlock in case we got to a device removal
event on a queue which is already in the process of
destroying the cm_id is this is blocking until all
events on this cm_id will drain. On the other hand
we cannot guarantee that rdma_destroy_id was invoked
as we only have indication that the queue disconnect
flow has been queued (the queue state is updated before
the realease work has been queued).
So, we leave all the queue removal to a separate ib_client
to avoid this deadlock as ib_client device removal is in
a different context than the cm_id itself.

Currently, the fc transport invokes nvme_fc_error_recovery() on every
io in which the transport detects an error. Which means:
a) it's really noisy on large io loads that all get hit by a link down.
b) we repeatively call nvme_stop_queues() even though queues are
stopped upon the first error or as first steps of reset_work.
Correct by:
Errors are only meaningful if the controller is in the LIVE state.
Thus, enact the reset_work only if LIVE. If called repeatively, state
will have already transitioned.
There's no need to stop the queues here. Let the first steps of
reset_work do the queue stopping.

if a nvme command is issued with an opcode that is not supported by
the target (example: opcode 21 - detach namespace), the target
crashes due to a null pointer.
nvmet_req_init() detects the bad opcode and immediately calls the nvme
command done routine with an error status, allowing the transport to
send the response. However, the FC transport was aborting the command
on error, so the abort freed the lldd point, but the rsp transmit path
referenced it psot the free.
Fix by removing the abort call on nvmet_req_init() failure.
The completion response will be sent with an error status code.
As the completion path will terminate the io, ensure the data_sg
lists show an unused state so that teardown paths are successful.

If a controller connection is attempted (say to a subsystem that
does not exist), the first attempt errors out. If another connect
is attempted, it crashes.
Issue is the prior controller has yet execute it's final put, thus
its still on lists. However, opts points on it have been cleared, thus
causing the crash if they are referenced.
Fix is to add the missing put after the nvme_uninit_ctrl() call on
the attachment failure.

Current fc transport code, on io termination, is calling
nvme_cleanup_cmd() followed by the transport dma unmap routine
which also calls nvme_cleanup_cmd(). Which means two kfrees occur
on the same address, raising havoc. This resulted in odd data errors,
effectively corruption..
Fix by removing the extraneous double calls. Call now occurs only in
teardown paths and as part of dma unmap routine.

NVMe 1.2.1 or later requires controllers to provide a subsystem NQN in the
Identify controller data structures. Use this NQN for the subsysnqn
sysfs attribute by storing it in the nvme_ctrl structure after verifying
it. For older controllers we generate a "fake" NQN per non-normative
text in the NVMe 1.3 spec.

While a NVMe Namespace is somewhat similar to a SCSI Logical Unit (and not
a Logical Unit Number anyway) there are subtile differences. Remove the
misleading comment.
