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.

so that the ADMIN connection will not be disconnected when shutdown the

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.

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.

There is a chance that admin qpair is being destroyed at

group pointer before sending a message to poll group's thread

5c9a8a3c41 lib/nvmf: Use qpair_get_listen_trid() to find a subsystem listener
There is a public API spdk_nvmf_qpair_get_listen_trid() and it can
get trid of the specified qpair safely for any transport including
pluggable transports.

The API was overlooked when implementing the multipath feature for
NVMe-oF target. trid pointer was added to struct spdk_nvmf_qpair and
was used to find a subsystem listener.

However, pluggable transports got seg. fault because trid of the
qpair was not set.

To avoid such segmentation fault for any transport, change
nvmf_ctrlr_create() to use spdk_nvmf_qpair_get_listen_trid().

The struct spdk_nvmf_qpair is located in the public header file,
and so leave the added trid for now. It will be deprecated eventually.

b10e305010 nvmf: In spdk_nvmf_request_exec, reverse order of subsystem and qpair
checks

Check if the subsystem is paused before checking whether the qpair is
active. The order of these checks doesn't really matter, but in the next
patch it will be more convenient to check the subsystem first.

fce9428772 nvmf: Async event support for discovery log change
Added asynchronous event notices for discovery log change
as per nvme fabrics spec 1.1. This allows a host with persistent
connection to discovery controller to automatically connect to any
new subsystem available to the host automatically.

According to nvme fabrics spec 1.1, if the connect command specifies a
non-zero keep alive timer value and the discovery controller does not
support asynchronous events then we need to return Connect Invalid.
Since SPDK does not implement this check instead added support
for asynchronous events in discovery controller.

4409007906 nvmf: Fixes double triggering of association timer
Fixes issue #1635.

Under rare circumstances, the CC.en and CC.shn are both set
which then results in setting the association timer twice.
This scenario was observed during hot plug testing when the
initiator tries to reset the subsystem that contains the
removed device.
The end result is that when the ctrlr is destructed, then
one of the timers can still fire and access freed memory.

2ec88c4f8c nvmf: Don't fail a property set command with invalid bits
If the initiator sends a property set command to a valid register, but
the value contains bits that are reserved by the NVMe specification,
don't fail the whole command. Just log an error message.

Previously, any valid bits set would take effect but then the command
would also fail. That confuses the initiator and thinks it must retry
the full property set.
