When data digest is enabled for a nvme tcp qpair, we can use accel_fw
to calculate the data crc32c. Then if there are multiple
c2h pdus are coming, we can use both CPU resource directly
and accel_fw framework to caculate the checksum. Then the datao value compare
will not match since we will not update "datao" in the pdu coming order.
For example, if we receive 4 pdus, named as A, B, C, D.
offset data_len (in bytes)
A: 0 8192
B: 8192 4096
C: 12288 8192
D: 20480 4096
For receving the pdu, we hope that we can continue exeution even if
we use the offloading engine in accel_fw. Then in this situation,
if Pdu(C) is offloaded by accel_fw. Then our logic will continue receving
PDU(D). And according to the logic in our code, this time we leverage CPU
to calculate crc32c (Because we only have one active pdu to receive data).
Then we find the expected data offset is still 12288. Because "datao" in tcp_req will
only be updated after calling nvme_tcp_c2h_data_payload_handle function. So
while we enter nvme_tcp_c2h_data_hdr_handle function, we will find the
expected datao value is not as expected compared with the data offset value
contained in Pdu(D).
So the solution is that we create a new variable "expected_datao"
in tcp_req to do the comparation because we want to comply with the tp8000 spec
and do the offset check.
We still need use "datao" to count whether we receive the whole data or not.
So we cannot reuse "datao" variable in an early way. Otherwise, we will
release tcp_req structure early and cause another bug.
PS: This bug was not found early because previously the sw path in accel_fw
directly calculated the crc32c and called the user callback. Now we use a list and the
poller to handle, then it triggers this issue. Definitely, it will be much easier to
trigger this issue if we use real hardware engine.

This commit fixes a race condition when calling free_ctrlr(),
nvmf_vfio_user_close_qpair->free_qp will set controller `ctrlr->qp[qid] = NULL`
finally, when calling free_ctrlr() we also need to check `ctrlr->qp[qid]`
is NULL or not, when there are multiple IO queues, we need a lock to protect
`ctrlr->qp[qid]`. However, the call to free_qp() in free_ctrlr() is valid
only when killing SPDK target, for all other cases, e.g: VM disconnected,
the queue pairs are already freed, so here we can process these different
cases separately, and avoid extra lock.

This patch revert commit 8f7d9ec. In function vtophys_iommu_init(), we
can use `dev->drvier` in RTE_DEV_FOREACH() loop to count number of devices
probed by device driver using vfio APIs, or we will count all the PCI devices
that bind to vfio-pci driver, only the probed device's IOMMU group is added
to vfio container.
The original implementation is correct to count `g_vfio.device_ref` in
vtophys_pci_device_added(), we don't need to count it in
vtophys_iommu_device_event() callback.

Currently, there is no way to prevent spdk_app_start() from calling
app_setup_signal_handlers() and setting SPDK's signal handlers.
We'd like to use our own set of signal handlers, therefore this
patch adds a flag to the spdk_app_opts struct that disables this
behaviour.

Previously the nvme_ctrlr_state_string() function
was only defined for DEBUG builds since it was only
used in DEBUGLOGs. So now that we're also using
it for an ERRLOG we need to define this function
in release builds as well.

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.

An error might occur after succesful transport creation
when the new transport is added to nvmf poll groups, e.g.
in nvmf_transport_poll_group_create. In that case
transport is not detroyed and poll groups are not fully
functional. To correct this behaviour, destroy transport if
spdk_nvmf_tgt_add_transport fails. Also update nvmf_tgt
initialization step to check that all poll groups were
created.

When poll_group is used, several qpairs share the same CQ
and it is possible to receive a completion with error (e.g.
IBV_WC_WR_FLUSH_ERR) for already disconnected qpair
That happens due to qpair is destroyed while there are
submitted but not completed send/receive Work Requests
To avoid such situation, we should not detroy ibv
qpair until we reap completions for all submitted
send/receive work requests. That requires some
rework in rdma transport and will be implemented
later

Poll group holds lists of qpairs in different states and
when we got rdma completion with error, we iterate these
lists to find a qpair which qp_num matches. qp_num
is stored inside of ibv_qp which belongs to spdk_rdma_qp
structure. When nvme_rdma_qpair is disconnected, pointer
to spdk_rdma_qp is cleaned but qpair may still exist in
poll group list and when we start searhing for qpair by
qp_num we may dereference NULL pointer.
This patch adds a check that pointer to spdk_rdma_qp
is valid before dereferencing it. To minimize boilerplate code,
wrap all check in macro. Add unit test to verify this fix.

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.

John Kariuki tested this patch on a system with
several Intel P5800X Optane SSDs, to determine the
performance impact of adding these two
spdk_trace_records() in the main NVMe I/O path.
The pathological case (512B random reads on a single
Xeon core) decreased from 13.10M to 12.88M, or 1.7%.
Normal workloads (4KB+) would incur a smaller penalty
since the I/O rate would be much lower - maybe even
unnoticeable..
This is a really valuable tracepoint to have enabled
by default, so I think this small amount of degradation
is acceptable.

The issue is that:
We call cb_fn firstly, then add the related idxd_ops into the
chan->ops_list. Then if in user's callback, we call spdk_idxd_submit_*
function gain, then we will allocate new idxd_opts first. So if there is
recursive spdk_idxd_submit_* in the call back function, then
we will exhaust all the ops_pool resources. And the function will
report -EBUSY issue in _idxd_prep_command function.
And this patch fixes this issue by adding back idxd_ops before calling
user's call_cb function.
