071d80f37b lib/nvmf: Add an internal API nvmf_subsystem_set_ana_state()
Add an internal API nvmf_subsystem_set_ana_state() to change the
ANA state of the subsystem listener whose trid matches.

ANA optimized state, ANA non-optimized state, and ANA inaccessible
state are supported. ANA change state is not used and ANA persistent
loss state is not supported.

After changing the ANA state of the subsystem listener, on each poll
group, controllers, whose the subsystem listener match, send ANA
change notice.

Initiators query ANA log page anyway if they receive ANA change
notification. False positive notification should be avoided but is
acceptable.

To avoid any concurrency conflict, simply compare ctrlr->listener and
the passed listener.

It may be better to execute nvmf_subsystem_set_ana_state() on the
subsystem thread but currently the RPC thread adds and removes a
listener to and from the subsystem, respectively, and the subsystem
has been suspended while executing nvmf_subsystem_set_ana_state().
Hence we keep this as a future enhancement.

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.

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.

Fixes #1129

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.

5e25bbdd49 nvmf/fc: Add listen address support in FC transport
Enables access control to allow subsystem access on one or more FC ports.

If a subsystem definition does not have a single valid "Listen" directive,
then the subsystem will allow dynamic listen address binding. For such
subsystems,
   * When a FC port comes online, FC transport will add port's address
to subsystem's listen list.
   * When a FC port goes offline, FC transport will remove port's address
from subsystem's listen list.

If subsystem definition has 1 or more valid "Listen" directives then FC ports
coming online or going offline will not affect subsystem's listen address
whitelist.

20b35d769d nvmf: don't keep a global discovery log page.
Keeping a global discovery log page was meant to be a time saving
mechanism, but in the current implementation, it doesn't work properly,
and can cause undesirable behavior and potential crashes. There are two
main problems with keeping a global log page.

1. Admin qpairs can be assigned to any SPDK thread. This means that when
multiple initiators connect to the host and request the discovery log,
they can both be running through the spdk_nvmf_ctrlr_get_log_page
function at the same time. In the event that the discovery generation
counter is incremented while these accesses are occurring, it can cause
one or both of the threads to update the log at the same time. This
results in both logs trying to free the old log page (double free) and
set their log as the new one (possible memory leak).

2. The second problem is that each host is supposed to get a unique
discovery log based on the subsystems to which they have access.
Currently the code relies on whether the discovery log page offset in
the request is equal to 0 to determine if it should load a new discovery
log page or use the cached one. This is inherently faulty because it
relies on initiator provided value to determine what information to
provide from the log page. An initiator could easily send a discovery
request with an offset greater than 0 on purpose to procure most of a
log page provided to another host.

Overall, I think it's safest to not cache the log page at all anymore
and rely on a thread local fresh log page each time.
