a158309ce5 nvmf/tcp: Remove the hd_is_read field.
Previously, this field is used to optimize the code.
When we receive the capsule cmd pdu, we need to allocate
the related buffer, if there is read or write request.
If the related buffer is not valid, then we cannot enter
the next pdu handling phase. So we use this field to mark.

After carefully checking the code, I think that we use
the tcp_req which is assoicated with the pdu, thus it is
efficient.

187e2dfbbf nvmf: use spdk_uuid_copy() API instead of memcpy.
For NVMeoF, extened host identifer is used which is exactly
the same size as uuid, while here, use uuid data structure
makes sense.  For NVMeoF reservation features, host identifier
need to be used with each registrant, using spdk_uuid_compare
becomes straightforward.

5aca5cd71b rdma: don't print a notice on QP state change.
This notice was scaring a lot of people because every time we disconnect
a qpair it tells the user that qpair is entering an error state. That is
part of the normal state flow of qpairs during disconnect, but makes it
seem like something is going wrong.

1180bf8343 rdma: clean up SGE definitions and properly set values
We have historically conflated SPDK_NVMF_MAX_SGL_ENTRIES and the maximum
number of SGEs associated with a wr data object. For now these are the
same thing, but there should be nothing tying the number of NVMe request
SGL elements to the number of rdma request wr sgl elements.
Also, clarify the rx_sge and tx_sge enums to reflect the actual maximum
number of SGEs associated with either the send and receive queues.
This change doesn't actually modify these values, but sets us up to do
things like split the data in an NVMe SGE into multiple WR SGEs in case
the buffer associated with the NVMe SGE is not contained in a single
RDMA mr.
We also need to store these values in the qpair for later usage.

Also configure the number of nvmf request iovs to correspond with this

90b4bd6cf9 nvmf/rdma: Fix QP shutdown procedure implementation
This patch implements the following QP shutdown flow:
1. Move the QP to ERR state
2. Post dummy work requests to send and receive queues
3. Poll CQ until it returns dummy work requests (with WR Flush Error status)
4. Call ibv_destroy_qp and release resources

In order to differentiate dummy and normal WRs new spdk_nvmf_rdma_wr
structure was introduced which contains type of WR. Since now it is
expected that wr_id field in ibv_recv/send_wr and ibv_wc always points
to this structure. Based on WR type wr_id can be safely casted to
correct container structure. In case of unsuccessful work completions
'opcode' can not be used for this purpose because it may be
invalid (see "IB Architecture Specification Volume 1", ch. 11.4.2.1
"Poll for completion").

NULL IO channel assigned due to some problem like out of resource,
for example, the NVMe SSD hardware itself has limited number
of IO qpairs. The subsystems in the particular poll group
could have zero valid channels. In this case, the creation of
assoicated poll group will fail and when adding the new qpair
to the specified poll group, needs to have a check and pick the
available poll group.

5d57386885 env_dpdk: spdk_mem_map_translate informs user of translation size.
This function will now check for whether or not a memory region is
contiguous accross 2MB map entries and return the total length of that
contiguous buffer up to the size specified by the user.

Also includes unittests
This series of changes is aimed at enabling spdk_mem_map_translate to
report back to the user the length of the valid mem_map up to the
function that requested the translation.
This will be useful when retrieving memory regions associated with I/O
buffers in NVMe-oF. For large I/O it will be possible that the buffer is
split over multiple MRs and the I/O will have to be split into multiple
SGLs.

82c3c30f44 trace: remove alias concept
This was added a long time back for tracking an rte_mbuf

The concept isn't useful now, so remove it to reduce

corner case in a later patch.

4bfb557d80 nvmf/rdma: recover qp from fatal errors
RDMA QP is attempted to recover after IBV_EVENT_QP_FATAL event
is received from IBV asynchronous event API.

RDMA QP is put into ERROR state and is not processing any inbound
requests. The outstanding requests are only allowed to COMPLETED
and FREE states, no outbound transfers are performed.

IBV_EVENT_QP_LAST_WQE_REACHED or IBV_EVENT_SQ_DRAINED event is
expected to follow IBV_EVENT_QP_FATAL, giving a go to draining of
all outstanding requests and freeing the associated resources.

The requests executed by block layer are gracefully allowed to
complete, but no outbound transfers are made.

Note, outstanding requests can not be reliably completed through
polling the CQ, as WC's with failure status might not have all
the fields valid. The failed WC's are dropped and the outstanding
requests are fetched from the appropriate state's linked list.

QP recovery is triggered when there is no more outstanding requests.
If QP recovery is completed succesfully, the RDMA QP is put back into
ACTIVE state, the QP disconnect is triggered otherwise.

Requests that are being put into IBV context are lost when
IBV QP breaks and its SQ drains.

In order to track NVMf/RDMA requests, RDMA QP has been
reworked to track requests at any state with queues of
requests for each state.

This allowed to get rid of a few intermediate queues and
request counters.

A couple of states has been added to track outbound requests
with and without data. They will be used by QP recovery for
freeing resources assigned to outstanding requests.

5518a327a8 nvmf/rdma: fix error paths in spdk_nvmf_rdma_create
Most of the error paths in this function leaked resources.  Make them
all use spdk_nvmf_rdma_destroy() so all resources are consistently
freed.

The spdk_io_device_register() call is moved to the top of the function
so that the io_device is always valid when calling the destroy function.

eb387189c2 nvmf: don't change NN while ctrlrs exist
This was partially fixed in commit 1e481d0438 ("nvmf: Do not allow NN
to change while connections present"), but we did not handle the case
where the user asked to add a NS with a NSID outside the current NN.

This patch reworks the logic (again) to be more straightforward and
hopefully more obviously correct.

Some confusion between max_allowed_nsid and max_nsid is also clarified;
if max_allowed_nsid is set, then max_nsid == max_allowed_nsid at all
times, so we don't need the extra logic when calculating NN in
spdk_nvmf_ctrlr_identify_ctrlr().

b95fc6fc64 nvmf: Return the correct error for out-of-range QID
This one is actually a bit tough to deduce in the specification.
The NVMe-oF spec says that QID errors detected in the RDMA
transport shall return an RDMA-specific error indicating
the problem. However, our code doesn't detect the error in
RDMA-specific code, and it isn't clear if the language is
a "must" or a "should".

The NVMe specification does clearly indicate what error
to return on invalid QID in response to a Create
I/O Queue Pair command. For now, return that while
we game plan whether we need to call into the RDMA
transport to correctly report this error.

NVMf cnx acceptor poller is changed to check the asynchronous events
from the RDMA devices.

RDMA async events are polled together with RDMA CM events; the file
descriptors are combined into a poll fd array and processed in a single
poll syscall.

The errors handler is an empty placeholder for this patch, it just
prints the kind of event read from the IB device context.
The work for implementing event handling is left for later.

cbbec6dd16 nvmf: make each io qpair recycled by its own thread
This patch selects part of commit:
adfa9f6dc7

In the previous patch, the failed reason is the logic
that admin qpair actively destroys the ioqpair when
the admin qpair is recevied early. For this part,
we need to investigate it later since for multiple core
usage in our current handling case, we possibly have
admin qpair firstly to enter the destruct phase even if
the initiator sends the I/O qpair deletion first. Thus,
the ioqpair deletion can be recycled twice.

And this patch is selecting the part of the logic:
only to make each ioqpair recycled by its own thread.

27d47b9a10 nvmf: make the qpair disconnnect in the right order.
Reason: Initiator sends the qpair deletion in wrong order.
The correct order should be all io qpairs deletion and then
the admin qpair deletion. However, nvme perf does not follow
this since we did not catch ctrlr + c. If we catch ctrlr + c,
we need to use the spdk app framework, or other methods. We should
support this in another patch.

Morever, to prevent the incorrect behavior causing the coredump
of target, we need also consider such case in our NVMe-oF target
design. And this patch, can solve this issue, it will defer the
admin qpair deletion when there are still active io qpairs.

Users can use RPC to add/remove a namespace to/from

generate an asynchronous event as an indication to
host when asynchronous event request is available.

While here, we also set the event with invalid log
identifier, so that the host doesn't need to clear
the event. Users can use Set Feature to disable
such event.

c3bc40a6ef io_channel: add return value to pollers
This will be used to track time used in pollers - each poller can now
indicate if it found any work to do or not.

For cases where it was obvious and the infrastructure was already in
place, existing pollers have been modified to return 0 or a positive
value to indicate whether work was done.  Other pollers have been
modified to return -1 by default, indicating that the poller isn't
indicating anything about whether work was performed.  This will allow
us to find un-annotated pollers easily in the future and fix them
incrementally.

With multiple core bining for NVMe-oF target,
the qpairs which belonging to the same ctrlr may
be scheduled to different cores. Thus there is
resource contention to access the struct spdk_nvmf_ctrlr.

And we put the thread info in polling group. Morever,
we introduce an admin_qpair in ctrlr. Since admin_qpair will
always be created at first and freed at last, to reference
this pointer is safe.

32ad027b0c nvmf: Adjust the resource free order for transport
Reason: In spdk_nvmf_subsystem_destroy, we call
spdk_nvmf_ctrlr_destruct(ctrlr), and this function
will still use the transport, so definitely, it is
a defect(reproduced in my platform).
So we need to defer freeing the transport resource.

ea1c15791f log: rename SPDK_TRACE_* to SPDK_LOG_*
Disambiguate the log components from the trace functionality
(include/spdk/trace.h).

The internal spdk_trace_flag structure and related functions will be
renamed in a later commit - this is just a find and replace on
SPDK_TRACE_* and SPDK_LOG_REGISTER_TRACE_FLAG().

- ioctl with FIONBIO
- fcntl with O_NONBLOCK
Those two should be equivalent for sockets used in SPDK.

During testing it was shown that VPP interprets only
the second type, so this patch changes all occurences of it.

When here, more descriptive error logs were set in case of
failure.

7ea544b46a nvmf: move poll groups to public API
The end goal is to have the application create one poll group per core.
Then each poll group will have a single CQ per network device and an I/O
channel per back-end storage device to poll.

This is just the first step toward that, which is to wire up the
creation of the per-core poll groups in the application.

Note that the app poll groups don't do anything yet.  We'll need
additional library API changes to make the library use the existing poll
groups, rather than creating a new poll group per subsystem as we do
right now.

5eb129647d nvmf/bdev: refactor read/write into separate funcs
This makes it easier to unit test the individual functions and also
easier to follow the logic.

These helpers will also be used in the upcoming Write Zeroes function.

Also cleans up the variable names to be consistent with the rest of the
code.

496ba0d273 nvmf: Temporarily remove hot plug support
The current hot plug support assumes only one thread
can access a subsystem at a time, but now that we're
changing that this will need to be reworked. In the
interest of making it easier to change the threading
model, remove hot plug support temporarily. We'll add
it back in once the threading model changes are done.

d5ce9cff63 nvmf: Transport polling now done by poll group
Instead of polling each individual qpair, polling is now
done by poll group. This allows transports to use more
efficient polling schemes in the future.

The RDMA transport as of this patch still just loops
over each qpair in the group and polls it individually,
so this patch results in no performance change yet.
