Modify admin passthru so that result field of passthru struct is always
populated. This should be safe since dw0 is either reserved or contains
command specific info. This is specifically meant for the namespace
management command when attempting to create a namespace. As per spec:
"Dword 0 of the completion queue entry contains the Namespace Identifier
created.". So for nvme cli and perhaps other application to see what is
the id of the namespace created there needs to be a way to pass the
information back.

In current implementation RDMA qpair is destroyed right after
disconnect. That is not graceful qpair shutdown process since
there can be requests submitted to HW and we may receive
completions for already destroyed/freed qpair.
To avoid this, only disconnect qpair in ctrlr_disconnect_qpair
transport callback, all other resources will be released in
ctrlr_delete_io_qpair cb.
This patch is useful when nvme poll groups are used since in
that case we use shared CQ, if the disconnected qpair has WRs
submitted to HW then qpair's destruction will be deferred to
poll group.
When nvme poll groups are not used, this patch doesn't change
anything, in that case destruction flow is still ungraceful.
However since CQ is destroyed immediately after qpair,
we shouldn't receive any requests which point to released
resources. A correct solution for non-poll group case
requires async diconnect API which may lead to significant
rework.
There is a bug when Soft Roce is used - we may receive
a completion with "normal" status when qpair is already
disconnected and all nvme requests are aborted. Added
a workaround for it.

The NVMe bdev module will support two features, delayed reconnect and
delete after multiple failures of reconnect to improve error recovery.
The recently added two APIs, spdk_nvme_ctrlr_reset_async() and
spdk_nvme_ctrlr_reset_poll_async(), were not good enough.
spdk_nvme_ctrlr_reset_ctx was not necessary. It had only a pointer to ctrlr.
Using a pointer to ctrlr directly saves us from undesirable malloc error
processing.
Separate spdk_nvme_ctrlr_reset_async() into spdk_nvme_ctrlr_disconnect()
and spdk_nvme_ctrlr_reconnect_async(). spdk_nvme_ctrlr_disconnect()
disconnects ctrlr including disconnecting adminq.
spdk_nvme_ctrlr_reconnect_async() moves the ctrlr state to INIT.
Then rename spdk_nvme_ctrlr_reset_poll_async() by
spdk_nvme_ctrlr_reconnect_poll_async().
Finally deprecate spdk_nvme_ctrlr_reset_async() and
spdk_nvme_ctrlr_reset_poll_async().
The following patches will change the NVMe bdev module to use these new APIs.

There is a bad memory corruption where the code for CUSE attempts to write
one byte (with value 0x1) after the memory is freed.
Context:
When the CUSE device is unregistered, the poller thread is signaled with
fuse_session_exit(), which writes the value 1 to fuse_session::exited.
The poller thread then detects with fuse_session_exited() that it must exit
the routing and finally destroys its own fuse session with
cuse_lowlevel_teardown() before it exits.
However, FUSE may also call fuse_session_exit() for its internal purposes.
I'm not sure exactly under what conditions that happens, but I added
some trace messages and I could clearly see that the CUSE thread exits
before it was requested to exit in cuse_nvme_ns_stop().
If the poller thread early-exits, it would destroy its own FUSE session
(and free the memory) before fuse_session_exit() gets executed, causing
the memory to be corrupted with a single byte of value 0x1.
Reproducer:
The bug can be reproduced by resetting the FUSE session to NULL after it
is destroyed. This will cuse_nvme_ns_stop() to crash with a segmentation
fault in fuse_session_exit() because it tries to access a NULL pointer.
static void *
cuse_thread(void *arg)
{
[...]
free(buf.mem);
fuse_session_reset(cuse_device->session);
+ cuse_device->session = NULL;
pthread_exit(NULL);
}
This fix:
The fix I suggest is to destroy the FUSE session with
cuse_lowlevel_teardown() after the thread is joined.

will try to reset the IO queue pair when timeout happens,
in `spdk_nvme_ctrlr_free_io_qpair`, we will abort the outstanding
IO requests first, then in the `nvme_pcie_ctrlr_delete_io_qpair`,
we will poll the CQ for any requests that have been completed by
the NVMe controller, if there are NVMe completions in the CQ,
we will finish them again, thus double completions happened.
Here we rename `nvme_qpair_abort_reqs` to `nvme_qpair_abort_all_queued_reqs`,
so the common layer will just abort queued request, and let each
transport to abort outstanding requests case by case.
Fix#2233.

The unit test test_nvme_cuse_stop() manually creates 2 cuse devices

input controller is fabrics controller or not, but it needs a controller
data structure as the input, so here we add another API to do the same
thing and it takes the transport type as the input, with this change,
both nvme and nvmf library can use the API.
Also we should treat UINT8_MAX(255) as valid fabrics transport type.

The qpair's state member is only 3 bits of a uint8_t,
and the in_completion_context bit is another bit in that
same uint8_t.
We know that the qpair's state is only ever updated by
one thread, but it is possible that the state could
be modified by one thread, while another thread
is modifying in_completion_context.
in_completion_context is only modified by the thread
that is polling the qpair (or the qpair's poll group).
But with async mode, another thread that has a qpair
on the same PCIe controller could poll its adminq and
reap the SQ completion for the qpair that's owned by
the other thread.
So do *not* set the generic qpair state to CONNECTED
from the SQ completion callback. Instead just set
the pcie_state to READY, and let the thread that owns
the qpair detect the qpair is READY and set the state
to CONNECTED itself.
Fixes issue #2157.

To make such translation possible, update structure
spdk_memory_domain_translation_result to use a pointer

Add a single iov structure or cases where translation
is always 1:1, it will make easier translation callback

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.

can get queued if a controller is being reset and it gets submitted
