e91d7428f9 nvme: print name of ctrlr state in timeout message
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.

ca5ce67f6e nvme/rdma: Ignore completion when we can't find qpair
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

00277bc5d5 nvme/rdma: Fix searching for qpair by qp_num
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.

971f07b9fb nvme: add tracing to pcie request path
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.

3cb9bc2593 nvme: add spdk_nvme_ctrlr_prepare_for_reset()
This new API signals that the ctrlr will soon be
reset. This allows the transport to skip unnecessary
steps in following calls to the driver prior to the
reset - for example, skipping PCIe DELETE_SQ/CQ
commands when freeing an IO qpair.

Note that if we are deleting a qpair after
prepare_for_reset was called, and the qpair is
still waiting for a CREATE_IO_CQ or CREATE_IO_SQ,
we cannot poll for those commands to complete,
but we also cannot free the qpair immediately.
So set a flag for this case to defer the
destruction until the outstanding CREATE_IO_CQ or
CREATE_IO_SQ callback is invoked (typically as an
aborted command when the reset happens).

0b51da144f nvme/tcp: Fix the C2hdata pdu receving logic.
There may be multiple C2H data pdus recevied.
So we should use the following steps:

1 Use the SPDK_NVME_TCP_C2H_DATA_FLAGS_LAST_PDU
to check whether it is a last pdu or not.
Then we will not cleanup tcp_req, i.e., tcp_req->datao
will not be cleaned.

Then use the SPDK_NVME_TCP_C2H_DATA_FLAGS_SUCCESS
to check whether the controller will use resp pdu
or not.

15b7d3bacc nvme/pcie: defer bad vtophys to completion context
The pcie layer can't always detect bad addresses
in the request at submission time - for example,
the transport may not have any trackers available
and the request gets queued at the generic
nvme level.

So this means that we might detect vtophys failures
during submission time, or in a process_completions
context - the latter happening when we complete
one request which triggers submitting a new request.

Currently if the vtophys failure happens during
submission context, we return -EFAULT to the
caller *and* call the completion callback.  Nowhere
else in the driver do we do both - the intention
has always been that you get one or the other.

So make all of this consistent by tagging the
tracker and the qpair with a flag if we hit a vtophys
error in the submission path.  Return 0 to the caller,
who will then later get a completion callback for the
bad request when the qpair is next processed for
completions.

I considered a separate TAILQ to hold these 'bad'
trackers, but that would have required duplicating
quite a bit of the tracker completion code for this
one case.  The flag on the pqpair is already in the
hot cacheline, so it's cheap to check it.  We will
only interate the outstanding_tr list when that flag
is set, so this should have zero impact to performance.

Fixes issue #2085.

ea0aaf5e85 nvme: Transports now set qpair state to NVME_QPAIR_CONNECTED inside

Previously this was assumed to be a synchronous process so the generic
layer transport code updated the state after .ctrlr_connect_qpair
returned. In preparation for making this support asynchronous mode,
shift that responsibility down into the individual transports.

While none of the transports actually do this asynchronously, insert a
busy wait in nvme_transport_ctrlr_connect_qpair to wait for the qpair to
exit from the CONNECTING state. None of the upper layer code can
actually correct handle a transport doing this asynchronously, so the
busy wait will cover that.
