The vfio-user target emulated NVMe device is treated as
PCIe NVMe SSD in the Guest VM, so when doing controller
reset or shutdown, we should abort the AERs which in the
NVMf library.
Users may switch kernel NVMe driver to SPDK NVMe driver
in the VM, without this fix, we will got "AERL exceeded"
response very frequently, because the AERs submitted by
previous driver will never be aborted in runtime.

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.

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.

When a qpair is destroyed and the qpair is the last,
_nvmf_ctrlr_free_from_qpair() (in lib/nvmf/nvmf.c) sends two messages,
one is for _nvmf_ctrlr_destruct() and another is for
_nvmf_transport_qpair_fini().
We do not know which of two completes earlier.
_nvmf_ctrlr_destruct() frees the qpair->ctrlr in the end.
On the other hand, _nvmf_ctrlr_free_from_qpair() calls
spdk_nvmf_poll_group_remove() in the end, and spdk_nvmf_poll_group_remove()
accesses the qpair->ctrlr to free queued requests to the qpair.
Before one recent change, spdk_nvmf_poll_group_remove() had been called
before _nvmf_ctrlr_free_from_qpair() was called.
Hence extrace the operation to free queued requests from
spdk_nvmf_poll_group_remove() and inline it into _nvmf_qpair_destroy().

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.

Currently we allocate buffers perf each SGL descriptor.
That can lead to a problem when we use NVME bdev with
PRP controller and length of the 1st SGL descriptor is
not multiple of block size, i.e. the initiator may send
PRP1 (which is SGL[0]) which end address is page aligned
while start address is not aligned. This is allowed by
the spec. But when we read such a data to a local buffer,
start of the buffer is page aligned when its end is not.
That violates PRP requirements and we can't handle such
request. However if we use contig buffer to write both
PRP1 and PRP2 (SGL[0] and SGL[1]) then we won't meet
this problem.
Some existing unit tests were updated, 1 new was added.

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

knowing the internal structure of spdk_bdev.

MMIO poller will process MMIO access.
This is useful when doing live migration, because the migration region
defined by VFIO is a BAR region, we should stop polling queue pairs
but ack the MMIO accesses during the live migration.

nvmf_poll_group_remove_subsystem_msg() disconnects all
qpairs associated with controllers in the specified
subsystem. If it finds any controllers that need to
be disconnected, it sends a message to the running
thread to execute the same function again later.
But when it runs again later, the qpair may no longer
be in the poll group, but there could still be
outstanding messages being sent between threads. For
example, _nvmf_qpair_destroy() needs to send a message
to the ctrlr->thread to clear the qpair mask bit.
All of this could result in the nvmf target starting
to destroy poll groups prematurely. Destroy poll
groups results in the nvmf spdk_threads exiting. If
there are still messages being processed from
the STOP_SUBSYSTEMS target state, we can get
use-after-free errors since processing of those
messages could access freed memory associated with
the exited thread.

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).

When we iterate qpairs that belong to a subsystem

some qpair can be disconnected on transport level,
e.g. the initiator may receive a disconnect for
the first qpair and disconnect others. That may lead
to a dead loop when we call spdk_nvmf_qpair_disconnect
with a callback, the callback is called immediatelly
and tries to disconnect the qpair again.
To solve this problem, move part of nvmf_poll_group_remove_subsystem
function to another function nvmf_poll_group_remove_subsystem_msg
which disconnects all qpair at once without any callback
and calls itself via thread_send_msg untill all qpairs are
disconnected.

The current implementation treats HPDA/CPDA as the absolute offset
to the beginning of the PDU where the payload data starts. This is
incorrect. The HPDA/CPDA actually specify where the payload data
should start such that the starting location is a multiple of HPDA
(for C2H PDU) or CPDA (for H2C PDU or CapsuleCmd PDU).
The other issue fixed is that the current implementation calculates
padding only when header digest is enabled. This is also incorrect.

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.

This is to prevent scenario where two versions exists with matching

Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.
Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.
Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04

VFIO is a framework that allows a physical device to be securely passed through
to a user space process. Typically, the user space process is a VM and the device
is passed through to it in order to achieve high performance. VFIO provides an API
and the required functionality in the kernel.
vfio-user is a framework that allows implementing PCI devices in userspace.
SPDK NVMf library provides the emulation of a NVMe device, combined with vfio-user
protocol, we can provide the emulated NVMe device to VM or client application, such
as SPDK NVMe perf.
This patch has dependency on libvfio-user library, users can start NVMe identify/perf
examples.

1. Start nvmf_target.
2. Use RPC to create a subsystem with namespace bdev.

nvmf_subsystem_state_change() protects against going
starting the pause/change/resume chain again if we
haven't completed the previous chain. But add
some asserts to make sure the cb_fn and cb_args
never get set twice. This also requires setting
them back to NULL after they've been used.

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.

If the user decided to disable ICD then we have several side effects:
1. SPDK prints several warnings/errors
2. SPDK doesn't create recv pipe and doesn't set SO_RCVBUF socket option.
I think that we should not rely on ICD only when we create recv pipe or
set SO_RCVBUF since data may be transferred in sgls via R2T/H2C and
we still need recv_pipe and SO_RCVBUF for better performance.
Alternative option is to set recv_buf_size as a maximum between

There are more transport on the way and we don't want to add
all their various opts into the single, generic structure.
We'll pass the JSON structure to transports instead. Then
the transport code can custom pull from the JSON any param
it wants.
To complement that, transports will now also have their own
JSON config dump callback. This was only done in the generic
nvmf.c so far, with conditions for RDMA and TCP.

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.

That occurred due to mempool has per lcore cache of 512 elements

each poll group cached extra 8 buffers.
The issue doesn't occur when we use mempool_get_bulk.

We will have ANA state per listener and per subsystem. On the other hand,
NVMe specification defines ANA state per controller.
However, it is possible that I/O qpair and admin qpair are different
listeners on a single controller.
Let's check if I/O qpair is on the same listener as admin qpair if
ANA reporting is enabled.
The case that I/O qpair is on a different listener from admin qpair
is not usual and so the purpose of this check is just to guard SPDK

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

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

A subsystem RPC is not transitioned to a paused state when there
are ios outstanding (tracked by subsystem poll group).
In general AERs, are not tracked as outstanding IOs. However,
there are 3 paths in nvmf_ctrlr_async_event_request which do not
adjust the outstanding io count.
If we get into any of these 3 paths, the subsystem pause can hang
forever.
The issue was reproduced with hot plug stress testing under load.
We can get into the second path (SPDK_NVME_ASYNC_EVENT_TYPE_NOTICE)
under these circumstances:
- An AER completion is sent to the initiator due to a namespace change
(e.g. hot remove/add)
- In this case, type is set to SPDK_NVME_ASYNC_EVENT_TYPE_NOTICE
- The initiator sends a new AER admin command, hitting the second path
where we return without adjusting the outstanding ios.

Generally, this patch did the following work:
Remove the destruct poller. I think that we do not need this,
the destruct poller is specially for Softwaare RoCE case.
Since SoftRoCE will not have IBV_EVENT_QP_LAST_WQE_REACHED event,
we will not wait the last_wqe_reached flag when srq is enabled.
So we can avoid using the poller.
And the purpose of this patch is to solve the coredump issue.
For example, if we run rdma local test such as, e.g.,
test/nvmf/host/bdevperf.sh --transport=rdma
The coredump reason: the qpair is freed twice. Because for RDMA transport,
we do not really remove the qpair from the group if the upper layer
does it.
The first time is called by nvmf_rdma_destroy_drained_qpair in nvmf_rdma_poller_poll,
and the second time is called by nvmf_rdma_qpair_reject_connection in
in nvme_rdma_close_qpair. Since nvme_rdma_close_qpair will always called,
so we need make sure that the qpair will be close after calling this function.
Otherwise we will have the double free qpair. So our approach here is add a flag
("to_close")in rqpair structure and make sure the rqpair be freed after the
"to_close" is set nvme_rdma_close_qpair

Since rqpair->qpair.group is set to NULL when we remove the
qpair from poll group, we fail to send event to qpair's thread.
This patch adds a pointer to io_chaneel to spdk_nvmf_rdma_qpair
structure and a function to handle poll_group_remove transport
operation. In this function we get io_channel from nvmf_tgt,
this channel will be used to get a thread for sending
async event notification. This also guarantees that the thread
will be alive while we are destroying qpair.

If the request is queued and is not in completing, we can abort
it safely.
If the state of the request is NEED_BUFFERING, the request is
queued to both tqpair->group->group.pending_buf_queue and
the queue per state.
If the state is AWAITING_R2T_ACK, the request is queued to the
queue per state.
Dequeueing from the queue per state is done in
nvmf_tcp_req_set_state(). Hence explicit dequeuing only when the
state of the request is NEED_BUFFERING.
Most abort operation is common between two cases. We can use fallthrough
in switch-case but factor out the common operation into a helper
function nvmf_tcp_req_set_abort_status() instead because we may use
the helper function in future and using helper function is easier to
read than fallthrough.

State machine is different among NVMe-oF transports and is

To implement abort operation for each NVMe-oF transport,
add a function pointer qpair_abort_request to struct spdk_nvmf_transport_ops
and a stub nvmf_transport_qpair_abort_request() to encapsulate
which transport is used.
The following patches will implement qpair_abort_request for each

spdk_nvmf_request_complete() for the abort request.
