13e5be0b8d lib/nvmf: Set missing fields if OPTPERF is set
As per the nvme specs,
If OPTPERF is set to ‘1’ indicates that the fields
NPWG, NPWA, NPDG, NPDA, and NOWS are defined for this namespace and
should be used by the host for I/O optimization

Setting NPWA, NPDG, NPDA same as NPWG and NOWS same as MDTS

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

3b1f13ef29 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)

Fixes #2055

1c81d1afa2 nvmf: clear ctrlr->listener in remove_listener
When removing a listener, there's a small window when the listener is
already freed, while the controllers that were created on that listener
are still active.  It happens, because the listener is removed before
disconnecting its qpairs and in turn destroying the controllers.

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.

814cd25882 nvmf: optimize log level for unsupported feature IDs and invalid property offset
Since we are using NVMf fabric library to emulate a PCIe based SSD via
vfio-user target, so there maybe some commands that are related with
PCIe SSD only, such as set/get features with interrupt coalescing
and Interrupt Mask Set/Interrupt Mask Clear registers.  Even the
NVMf library doesn't support that, it is not a fatal error to Host
NVMe driver, so here we use the info log instead of error log for
this case so that to avoid noise logs.

Fix #2036.

4fa3d99131 nvmf: don't start the association timer poller for vfio-user
When users remove kernel NVMe driver in the VM, after 120 seconds,
SPDK NVMf target will disconnect ADMIN queue pair due to association
timer timeout, and for vfio-user transport, the ADMIN queue pair
connection is associated with the socket connection, so when probing
the NVMe controller again, because there is no active ADMIN connection
for fabric register R/W commands, it will cause segment fault.

Here we set the association timeout value to 0 for vfio-user transport,
so that the ADMIN connection will not be disconnected when shutdown the
controller, the ADMIN queue pair will be disconnected when the socket
connection breaks.

ac3a42b15c nvmf: retry connect commands internally when subsys not ready
It is better to not fail connect commands when a subsystem
is not ready.  The host will not be expecting that and will
typically treat it as a catastrophic failure (i.e. it won't
retry the connect).

So instead when this situation occurs, start a poller for
the connect request.  We will continue to retry processing
it until the subsystem is ready to handle it.

Fixes issue #1985.

164bfddf24 nvmf: don't set aerl=0 for non-discovery controllers
Commit b7cc4dd added support multiple AERs, but didn't
remove the code that hardcodes aerl=0 for non-discovery
controllers.  So even though the target now supports
multiple AERs, we never indicate that for non-discovery
controllers.

The spec also recommends that implementations support
a minimum of 4 AERs - so the current behavior is not
recommended.

It seems that at least on Windows (when testing with
vfio-user transport) we see the limit get exceeded
which results in ERRLOGs.  Let's keep the ERRLOG there
for now, assuming that once we report we support 4
AERs that Windows won't try to send more than that.

Fixes issue #2000.

68ff34bc66 include/nvme_spec.h: improve portability
Aspects of bit fields are 'implementation defined'.  On some platforms
alignment will occur if two adjacent fields are of different types. This
occurs in spdk_nvme_feat_async_event_configutation after the crit_warn
member which is effectively an int8_t, followed by an int16_t. There
isn't a generic way of changing the compiler's behaviour, so the best
options are:

- Change crit_warn to a uint32_t bit field and copy the value to/from
  a spdk_nvme_critical_warning_state variable to use it. This requires
  changes to code using the field.

- Adjust the structure definition to use smaller types to avoid the
  problem. This preserves existing semantics, but the field order will
  need to be reviewed if big-endian support is ever added (other places
  in nvme_spec.h will need similar attention). A second reserved field
  is required.

Use smaller types which seems the most straightforward option. Adjust
the use of the spdk_nvme_feat_async_event_configuration reserved fields
in lib/nvmf/ctrlr.c.

The new structure is binary compatible and the fields behave in the same
way, with the exception of an additional reserved field, so updating
CHANGELOG.md probably isn't necessary.

specific namespace also allows for the removal of that namespace without
impacting I/O to other namespaces in the subsystem.

813869d823 nvmf: Fix possible race condition when adding IO qpair
There is a chance that admin qpair is being destroyed at
the moment when IO qpair is added to a controller due to e.g.
expired keep alive timer. Part of the qpair destruction process
is change of qpair's state to DEACTIVATING and removing it
from poll group. We can check admin qpair's state and poll
group pointer before sending a message to poll group's thread
and fail connect command.
