This code has a similar potential problem as the identify

We also need to fix the unit tests to initialize the iovs.

In the previous fix:
adc2942ad nvmf: nvmf_ctrlr_get_log_page use iovs to store the log page
a data corruption bug in the log page code was fixed. Previously, it
used req->data, which may be too short a buffer in the case that the
buffer is split across more than one IOV. req->data is never safe to use
in this situation. The code was changed to use the provided iovs instead
of req->data.
However, the identify command handling was still vulnerable to this
problem, and has been seen in real life at least with a CentOS guest VM.
The fix is basically the same: use the IOV utility functions to write
out the response instead of directly trying to use req->data.

If a lot of qpairs are connected all at once, the
RDMA optimal_poll_group logic does not work correctly,
because it only accounts for qpairs that received
their CONNECT capsule. Now that we have a counter
for a poll group's unassociated qpairs, use that value
to supplement the current io qpair count.
We can just assume for now that all of these unassociated
qpairs are io qpairs. That won't always be true, but
for purposes of picking the optimal poll group it is
sufficient.
Note that for RDMA, we could increment the counters
based on the RDMA qpair ID in the private data in the
rdmacm connect, but to keep the code simpler and common
across all transports, we defer the accounting until
after receiving the CONNECT command, so that it is
the same for all transports.
Fixes issue #2800.

We make decisions on how to pick a poll group for a new
qpair by looking at each poll group's current_io_qpairs
count. But this count isn't always accurate since it
doesn't get updated until after the CONNECT has
been received.
This means that if we accept a bunch of connections
all at once, they may all get assigned the same poll
group, because the target poll groups counter doesn't
get immediately incremented.
So add a new counter, current_unassociated_qpairs,
to account for these qpairs. We protect this counter
with a lock, since the accept thread will increment
the counter, and the poll group thread will
decrement it when the qpair receives the CONNECT
allowing us to associated with a subsystem/controller..
If the qpair gets destroyed before the CONNECT is
received, we can use the qpair->connect_received
flag to decrement current_unassociated_qpairs.

source range.
Note, that command support in the controller is initialized once on
controller create. If another namespace which doesn't support copy
command is added to the subsystem later, it will not be reflected in
the controller data structure and will not be communicated to the
initiator. Attempt to execute copy command on such namespace will
fail. This issue is not specific to copy command and applies also to

To support SQs allocated to a poll group other than the controller's
main poll group, we need to make sure to poll those SQs when we wake up
and handle the controller interrupt. As they will be running in a
separate SPDK thread, we will arrange for all poll groups to wake up
when we receive an interrupt corresponding to a vfio-user message
arriving.
This can mean needless wakeups: we don't (yet) have a mechanism to only
wake up the poll groups that correspond to a particular SQ write.
Additionally, as we don't have any notion of a poll group per
controller, this ends up polling all SQs in the entire poll group, not
just the ones corresponding to the controller we were handling.
As this has potential performance issues in many cases, it defaults to
disabled.

When emitting the JSON-RPC text for saving the
current configuration, add the listeners last.
This is usually the preferred order when
configuring a new subsystem - it is better to have
all of the namespaces and hosts added to the subsystem
before adding the listener to allow hosts to connect
to it. We support namespace hotplug but there's
no need to unnecessarily generate hotplug events
if we can avoid it.

If initiator and target run on the same application, and initiator
uses SRQ, target may get async events for initiator, e.g.,
IBV_EVENT_QP_LAST_WQE_REACHED unexpectedly.
The reason is initiator and target may use the same device
simultaneously and only target polls async events.
Target sets attr.qp_context to rqpair when creating QP, but initiator
sets attr.qp_context to NULL when creating QP.
Hence one simple fix is to ignore async events whose qp_context is
NULL.

Multiprocess is only supported by a few libraries (e.g. NVMe driver).
Other libraries that don't support it will often fail on mempool

Thinking about memory thrashing, we should use the same memory as

We cannot count AERs as outstanding IO for purposes
of subsystem pause, because we cannot expect them
to be completed. Previously we would account for this
in nvmf_ctrlr_async_event_request() by decrementing
the counter, but this did not consider cases in the
calling function (nvmf_ctrlr_process_admin_cmd) where
an AER might complete with error before this function,
resulting in the counter getting stuck indefinitely
with a >0 value.
Rather than adding a decrement in all of those
error cases, do a single check at the beginning
of nvmf_ctrlr_process_admin_cmd, and remove the
one from nvmf_ctrlr_async_event_request.

pointless since we don't generate any migration data at this state, so
if the vfio-user client reads migration data it will be garbage. Even
worse, we don't re-initialize pending_bytes in stop-and-copy state, so
if the vfio-user client reads the entire migration data in pre-copy state
then there will be nothing left to read in the stop-and-copy state,
which is where we actually produce the migration data. This results in
corruption of the controller's state (e.g. queues).
This patch ensures that migration data are available in the
stop-and-copy state, by setting pending_bytes accordingly only in that
state.

The read_data, write_data, and data_written migration callbacks assume

with this patch we ensure we don't ignore unsupported ranges.

Update libvfio-user such that the SGL access APIs can be used
concurrently. We are guaranteed that the guest memory remains mappable
now that the vfio-user transport has implemented quiescence.
This is currently only really useful (for a single controller) in poll
mode, but shouldn't break interrupt mode, as we still ensure all a
controller's queues are on the same poll group in that case.

In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:
1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names
Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

While we are quiesced, we're not allowed to access guest memory via the
SGL APIs. Refuse to process any commands unless we're in RUNNING state.
We need to synchronize with each poll group via a message before we can
call vfu_device_quiesced(), otherwise we could still be processing
commands via nvmf_vfio_user_sq_poll().
For interrupt mode, we then might miss processing commands in a
corresponding interrupt callback, so make sure we process them when we
return to RUNNING state.

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.
