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.

- the controller stops processing any outstanding admin or I/O

- all I/O SQs and CQs are deleted.
In a full controller reset sequence for a PCIe controller, if we do
a controller level reset first, we can abort outstanding commands
after the hardware has actually been stopped.
For NVMe-oF controller, each I/O qpair is an independent network

Whenever that time is exceeded, a callback is immediately executed.
However, depending on the stage of the discovery process, we might need
to wait a while before actually stopping it (e.g. because a controller
attach is in progress). That means that a discovery service might be

the NVMe bdev module supports round robin algorithm for active-active

The multipath policy, active-passive or active-active, is managed per

nvme_bdev_channels.
Different from active-passive, active-active caches even non_optimized

If we specify a preferred path manually for each NVMe bdev, we will
be able to realize a simple static load balancing and make the failover
more controllable in the multipath mode.
The idea is to move I/O path to the NVMe-oF controller to the head of
the list and then clear the I/O path cache for each NVMe bdev channel.
We can set the I/O path to the I/O path cache directly but it must be
conditional and make the code very complex. Hence, let find_io_path() do
that.
However, a NVMe bdev channel may be acquired after setting the preferred
path. To cover such case, sort the nvme_ns list of the NVMe bdev too.
This feature supports only multipath mode. The NVMe bdev module supports
failover mode too. However, to support the latter, the new RPC needs to
have trid as parameters and the code and the usage will be come very
complex. Add a note for such limitation.
To verify one by one exactly, add unit test.

When sending a fused compare and write command, we pass a callback
bdev_nvme_comparev_and_writev_done that we expect to be called twice
before marking the io as completed. In order to detect if a call to
bdev_nvme_comparev_and_writev_done is the first or the second one, we
currently rely on the opcode in cdw0. However, cdw0 may be set to 0,
especially when aborting the command. This may cause use-after-free
issues and this may call the user callbacks twice instead of once.
Use a bit in the nvme_bdev_io instead to keep track of the number of
calls to bdev_nvme_comparev_and_writev_done.

Add an new RPC bdev_nvme_get_io_paths to query all active I/O paths.
One io_path belongs to One nvme_bdev_channel.
Each nvme_bdev_channel is associated with one nvme_bdev.
If the RPC bdev_nvme_get_io_paths has a bdev name as a parameter
it can use spdk_for_each_channel() simply for the corresponding
nvme_bdev.
However, users will want to know I/O paths of all nvme_bdevs like
the RPC bdev_get_bdevs.
One io_path has one nvme_qpair. One nvme_qpair belongs to one
nvme_poll_group. By relying on these relationships, the RPC
bdev_nvme_get_io_paths traverses all nvme_poll_groups by using
spdk_for_each_channel() to g_bdev_nvme_ctrlrs.
The RPC bdev_nvme_get_io_paths has two modes, display all or
the specified NVMe bdev's active I/O paths.
The specified bdev name is used just for comparison and empty
array is returned if no matched io_path is found.

Previously, only if admin qpair gets error, bdev_nvme_failover() was
called.
However, I/O qpair may get error earlier than admin qpair. In this case,
bdev_nvme_failover() was called but reset was already in progress. So
bdev_nvme_failover() returned without doing anything.
bdev_nvme_reset_complete() executes bdev_nvme_failover() if reset
failed. However the test time of test/nvmf/host/failover.sh was very
short. Timeout came before trying bdev_nvme_failover().
We can replace other bdev_nvme_reset() calls by bdev_nvme_failover()
but this patch focuses on the critical case.

The raid bdev may receive IO requests after the raid layer
invokes spdk_bdev_unregister function. This patch moves the
raid_bdev->module->stop to the raid_bdev_destruct function.
Then there will be no IO after the raid_bdev->module->stop
is invoked.
Below is a way to reproduce this issue:
(1) create a malloc bdev
sudo ./scripts/rpc.py bdev_malloc_create --name malloc0 128 4096
(2) create a concat bdev base on the malloc bdev
sudo ./scripts/rpc.py bdev_raid_create --name concat0 \
--raid-level concat --base-bdevs malloc0 --strip-size-kb 4
(3) create a lvstore base on the concat bdev
sudo ./scripts/rpc.py bdev_lvol_create_lvstore \
--cluster-sz 4194304 --clear-method unmap concat0 lvs0
(4) remove the concat bdev
sudo ./scripts/rpc.py bdev_raid_delete concat0
In the step(4), the spdk app will crash because an IO request
is sent to the concat bdev after the concat_stop is invoked.

The concat module can combine multiple underlying bdevs to a single
bdev. It is a special raid level. You can add a new bdev to the end of
the concat bdev, then the concat bdev size is increased, and it won't
change the layout of the exist data. This is the major difference
between concat and raid0. If you add a new underling device to raid0,
the whole data layout will be changed. So the concat bdev is extentable.

For now, let's not fail the bdev_nvme_start_discovery

For RDMA transport, current synchronous qpair disconnect occupied CPU for
a second when qpair disconnect gets timeout.
To remove this limitation, we will do the following:
- make spdk_nvme_ctrlr_disconnect_io_qpair() asynchronous,
- spdk_nvme_qpair_process_completions() returns -ENXIO only if the
qpair is actually disconnected.
Even at this patch, spdk_nvme_poll_group_process_completions() invokes
disconnected_qpair_cb only if a qpair is actually disconnected. This
behavior will be maintained.
To use the upcoming asynchronous qpair disconnect easily, when
deleting a ctrlr_channel, disconnect the qpair, and then free the qpair
and release a reference to the poll group when the qpair is actually
disconnected.
We need to delete a nvme_qpair asynchronously after the corresponding
nvme_ctrlr_channel is deleted and defer the deletion of the corresponding
nvme_ctrlr until the nvme_qpair is deleted. To satisfy this requirement,
utilize the reference count of the nvme_ctrlr.
disconnected_qpair_cb() may call spdk_nvme_ctrlr_free_io_qpair() and
spdk_io_device_unregister() successively. The spdk_io_device_unregister()
will execute spdk_nvme_detach_async() from its callback.
spdk_nvme_ctrlr_free_io_qpair() has to complete earlier than
spdk_nvme_detach_async() starts. spdk_nvme_ctrlr_free_io_qpair() is
executed after unwinding stack. spdk_nvme_detach_async() is executed
after sending a message. Sending message is later than unwinding stack.
Hence the requirement is satisfied naturally.
spdk_io_device_unregister() for the nvme_ctrlr is required to be called
on the nvme_ctrlr->thread. To satisfy this requirement, redirect
nvme_ctrlr_unregister() to the nvme_ctrlr->thread. This change is too
small to stand as an independent patch. So include the change in this
patch.
