a36785df71 nvmf: Add ZNS specific identify functions for NVMe-oF ZNS support
In order to connect to a zoned SPDK NVMe-oF target the ZNS specific
identify functions must be implemented and the supported ZNS opcodes
must be set accordingly.

Implementing ZNS specific identify functions to return the 'I/O Command
Set specific Identify Namespace data structure (CNS 05h)'
(`spdk_nvmf_ns_identify_iocs_specific`) and 'I/O Command Set specific
Identify Controller data structure (CNS 06h)'
(`spdk_nvmf_ctrlr_identify_iocs_specific`).

Those functions return a null filled data structure for any I/O Command
Set other than ZNS.

a6dbe3721e update Intel copyright notices
per Intel policy to include file commit date using git cmd
below.  The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc).  Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line.  Simply there for
consistency.

c60cb1a8be lib/nvmf: don't raise assertion in nvmf_tgt_destroy_cb
While running into this function, even the subsystem can't be
destroyed due to error subsystem state, it's better to continue
the execution.

Continue to fix #2590, QEMU is stuck for the failure case, and
nvmf target should process such error because it may support other
normal subsystems at the same time.

78ca4b27c5 nvmf: don't raise assertion when destroying an non-inactive subsystem
Sometimes VM may get a kernel panic when starting, and SPDK CI will kill
`nvmf_tgt` after 60 seconds, and for this exception, SPDK will raise an
assertion when destroying the subsystem, while here, we remove this
assertion and print the error information.

CI will still mark this case as a failed case, then we can use this error
information to understand error subsystem state in vfio-user.

Fix issue #2590.

8dd1cd2104 check_format: For C files only, fix return type breaks
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.

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
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.

25bc221cee nvmf: deprecate automatic discovery listener
Currently we accept connections to the discovery
subsystem on any listener that has been added to
any subsystem (not just the discovery subsystem).

This is not proper behavior, especially for TCP.  TCP
defines port 8009 (not 4420) as the discovery port,
so the current behavior means that if NVM subsystems
are listening on port 4420, then the discovery
subsystem by default is listening there too.

For now, continue to allow connections, but print
a warning message when someone connects to the
discovery subsystem on a listener trid that wasn't
previously added.

478f652436 nvmf: Update controller desctruction process
There is a race condition between controller destruction and
subsystem state change, e.g. admin qpair may already be freed
when a namespace is added or removed. As result in function
poll_group_update_subsystem we may get heap-use-after-free error

Another problem is that some qpair's live time may exceed controller's
life time. To avoid it, start controller destruction process when the last
qpair finished the disconnect process (previously controller started
the descruction process before the last qpair starts to disconnect
and it could lead to raise conditions)

to update the discovery log when adding a host, or setting

This eliminates some unnecessary discovery log update

it has any listeners).

Update unit test to check the adding a host to a
subsystem without listeners does not rev the genctr.

9ac2cf7ff0 nvmf: don't update discovery log on subsystem create/delete
The discovery log isn't updated when a subsystem is created
or deleted, it's only updated when a listener for a
subsystem is added or removed.

So remove the nvmf_update_discovery_log() in the subsystem
create and delete paths. They just generate extra AER
completions that potentially cause the host to do unneeded
work.

Note that if a subsystem is deleted with active listeners,
the subsystem delete path will remove each of the listeners
before deleting the subsystem itself.  So the discovery log
will still get updated when those listeners are removed.

The ctrlr->listener pointer is now cleared when a listener is freed and
its value is checked for NULL before each use.

97385af196 nvmf: Fix double controller destruction when subsys is deleted
When a subsystem is being deleted, we disconnect all qpairs
and when the last qpair for some controller is disconnected,
we start controller desctruction process. This process requires
to send a message to subsystem's thread to remove the controller
from the list in the subsystem and after that send a message to
controller's thread to release resources.
The problem is that the subsystem also destroys all attached
controllers. This order is unpredictable and we may get
heap-use-after-free or double free.

To fix this problem we can rely on the fact that the subsystem
can only be destroyed in incative state, that means that all
qpairs linked to the subsystem are already disconnected and
all controllers are already destroyed or in the process of
destruction.

spdk_nvmf_subsystem_destroy API is now can be asyncrhonous,
it accepts a callback with cb argument.

785d10b5c7 nvmf: Make ANA state not only per subsystem listener but also per ANA group
Refine ANA state from per subsystem listener to per subsystem listener
per ANA group.

Add an array of ANA state per ANA group to subsystem listener. The array is
indexed by ANA group ID - 1.

Then in I/O paths, we get ANA state by
    ctrlr->listener->ana_state[ns->anagrpid - 1].

The NVMe specification indicates the existence of NVM subsystem specific
ANA state when FFFFFFFFh is specified as NSID for the Get Features
and the Set Features commands. For these, we return the optimized state.

Update the nvmf_subsystem_get_listeners RPC to return all ANA states
of the underlying ANA groups. The nvmf_subsystem_get_listeners RPC is
not matured and not used in the test code yet. Hence compatibility is
not high priority.

07bfc3cbe9 nvmf: Add anagrpid to ns and count number of ns per ANA group in subsystem
This is the first patch in the patch series to control ANA states not only
as a unit of subsystem listener but also as a unit of ANA group and create
user preferred mapping between namespaces and ANA groups within a single
subsystem.

This patch adds anagrpid to both spdk_nvmf_ns and spdk_nvmf_ns_opts, and adds
ana_group array to spdk_nvmf_subsystem to count number of namespaces per ANA
group within a single subsystem. The size of the ana_group array is equal
with the size of the namespaces.

For each subsystem, allocate ana_group array regardless of the value of
ana_reporting of the subsystem.

For each namespace, at its creation, initialize anagrpid explicitly to be equal
with nsid by default and increments the corresponding entry of the ana_group
array of the subsystem regardless of teh value of the ana_reporting of thee
subsystem.

Hence the contents of the created ANA log page is not changed even if the
algorithm to crete ANA log page is changed.

Additionally this patch adds a unit test case that one ANA group
has multiple namespaces.

Add the parameter ana_reporting into JSON config dump by adding and

Besides, previously the JSON RPC nvmf_subsystem_get_listeners had
ana_state regardless of the value of ana_reporting. We make it
conditional in this patch. The JSON RPC nvmf_subsystem_get_listeners
had not been used in the test code in the repository. Hence this

fa79643725 nvmf: remove struct spdk_bdev definition dependencies
1) use spdk_bdev_get_name() accessor
2) use __SPDK_BDEV_MODULE_ONLY #define

The latter allows nvmf to just get the spdk_bdev_module
definitions and APIs that it needs for claiming bdevs
for purposes of avoiding the same namespace used in
different subsystems.

This also ensures that future changes to structures
like spdk_bdev and spdk_bdev_io will not cause
lib/nvmf so version changes.

Note: we include bdev_module.h explicitly in the
nvmf/subsystem unit tests now, before including
subsystem.c, because the unit tests do depend on
knowing the internal structure of spdk_bdev.
