3d8904c66b nvmf: Add discovery filtering rules
SPDK nvmf target reports all listeners on all subsystems
in discovery pages, kernel target reports only subsystems
listening on a port where discovery command is received.

NVMEoF specification allows to specify any addresses/
transport types. Ch 5: The set of Discovery Log entries should
include all applicable addresses on the same fabric as the
Discovery Service and may include addresses on other fabrics.

To align SPDK and kernel targets behaviour, add filtering
rules to allow flexible configuration of what should be
listed in discovery log page entries.

Fixes #2082

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.

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.

6497b0774e nvmf: add max_io_size validation
The max_io_size transport option should be a power of 2 and be >= 8KB.

Max data tranfer size is defined in NVMe-oF spec as 2^(mdts cmd field) * 4KB.
Mdts cmd field is calculated as spdk_u32log2(transport->opts.max_io_size / 4096),
so max_io_size < 8KB results in mdts=0, which means no size limit (according to spec).

User can set max_io_size = 0 explicitly to allow no size limit.

d67119d8bd nvmf: Don't require a full subsystem pause to change the allowed hosts
The list of allowed hosts is only checked during handling of CONNECT
commands - not in the main I/O path. Protect that list with a mutex
instead of requiring a full pause of the subsystem to allow
dynamic management of the allowed hosts without impacting any
active I/O.

6f2265734d lib/nvmf: Optionalize ANA reporting feature
After supporting ANA reporting by default, Linux kernel 5.3 reported
error when parsing NVMe ANA log. The newer kernel fixed the issue
but we should optionalize ANA reporting feature to avoid error for
Linux kernel 5.3 or before.

Add a bool variable ana_reporting to struct spdk_nvmf_subsystem
and disable ANA reporting and initialization of related variables
if it is false. We can expose MNAN (Maximum Number of Allowed
Namespaces) even if ANA reporting is disabled. But MNAN is not
required if ANA reporting is disabled. So do not set MNAN if it is
false too.

Add a public API spdk_nvmf_subsystem_set_ana_reporting() to set
ana_reporting by the nvmf_create_subssytem RPC.

The next patch will add ana_reporting to nvmf_create_subsystem RPC.

2fa51eeb46 lib/nvmf: Make spdk_nvmf_poll_group_destroy() asynchronous
The next patch will create poll group threads dynamically for
NVMe-oF target, and will need to wait for completion of poll group and
I/O channel destroy. This is a preparation for the next patch.

Add callback function and its argument to spdk_nvmf_poll_group_destroy(),
and to struct spdk_nvmf_poll_group, respectively.

The callback has not only cb_arg but also status as its parameters even
if the next patch always sets the status to zero. The reason is to follow
spdk_nvmf_tgt_destroy's callback and to process any case that the status
is nonzero in future.

spdk_nvmf_poll_group_destroy() sets the passed callback to the passed
poll group.

Then spdk_nvmf_tgt_destroy_poll_group() calls the held callback in the
end.

This change will ensure all pollers are being unregistered and
all I/O channels are being released.

4dba507224 nvmf/tcp: Simplify qpair resource initialization
The resources allocated to a queue pair do not need to be directly
correlated to the queue size requested by the initiator in NVMe-oF, as
long as enough resources are present. The RDMA transport, for instance,
does complex pooling of the resources behind the scenes when using a
shared receive queue.

Simplify the resource allocation for a TCP qpair to just always allocate
the max allowed queue size right away. This is a configurable parameter,
so system administrators can adjust for their needs. The initiator may
then request a queue size less than or equal to that, which will only be
enforced by queue depth counting and not impact the actual number of
resources allocated on the target.

This change relies on the MaxC2HSize being equal to the Maximum Data
Transfer Size (MDTS) reported. That is the default configuration, but
MDTS is configurable. Changing the MDTS with this patch to a value
larger than 128k will cause the target to break. This is addressed in
the next patch in this series.

2167c68d18 lib/nvmf: nvmf target stops to listen when subsystem is destroyed
There is a spdk_nvmf_tgt_listen() which opens a port for specified
transport (trid) which opens possibility to accept new connections
from initiators. However there is no counterpart of this function
(i.e. spdk_nvmf_tgt_stop_listen()), which would stop listening.
Instead the current code relies on spdk_nvmf_subsystem_destroy()
to stop the listener, which seems to be wrong.

3fa2205647 lib/nvmf: custom admin cmd handler
This commit provides the capability to install a
    custom admin command handler for NVMF.
    It can be used to implement or replace NVMe admin commands that
    are currently not handled by the NVMF subsystem.

    The handler implementation is pretty generic and the handler function
    has to figure out what to do with the command based on the bdevs
    that are configured for the subsystem.
    In cases where admin commands need to be forwarded to an NVMe bdev,
    the commit provides functions that allow access to the underlying bdev.

    There is an example handler in lib/nvmf/custom_cmd_hdlr.c.
