disabled its compilation.
For details please see:
https://review.spdk.io/gerrit/c/spdk/dpdk/+/9217
Starting with DPDK 21.11 QAT_SYM and QAT_ASYM were
merged together, so it is no longer possible to
disable it QAT_ASYM as it was before.
As vbdev_crypto didn't make use of it,
this driver is now skipped in preparation for

From SAM-4, section 5.13 (Sense Data);
“When a command terminates with a CHECK CONDITION status, sense data shall be returned
in the same I_T_L_Q nexus transaction (see 3.1.50) as the CHECK CONDITION status. After
the sense data is returned, it shall be cleared except when it is associated with a unit
attention condition and the UA_INTLCK_CTRL field in the Control mode page (see SPC-4)
contains 10b or 11b.”
SPDK does not set UA_INTLCK_CTRL to 10b or 11b, so we set the unit attention condition
immediately against a single IO or Admin IO after reporting it via a CHECK CONDITION.
Once the failed IO received at iSCSI initiator side, it will be retried. In the case of
resize operation, if there is no IO from iSCSI initiator side, the unit attention
condition will be delayed to report until the first IO is received at the iSCSI target
side.
Meanwhile, we clear the resizing (newly added) flag on our SCSI LUN structure after
first time we report the resize unit attention condition.
The kernel initiator won’t actually resize the corresponding block device automatically.
It will report a uevent, and then you can set up udev rules to trigger a rescan. SPDK
iSCSI initiator will automatically report the LUN size change.

If ctrlr_loss_timeout_sec is set to -1, reconnect is tried repeatedly
indefinitely, and I/Os continue to be queued.
This patch adds another option fast_io_fail_timeout_sec, a flag
fast_io_fail_timedout to nvme_ctrlr.
If the time fast_io_fail_timeout_sec passed after starting reset,
set fast_io_fail_timedout to true not to use the path for I/O submission.
fast_io_fail_timeout_sec is initialized to zero as same as
ctrlr_loss_timeout_sec and reconnect_delay_sec.
The name of the parameter follows the famous DM-multipath, its fast_io_fail_tmo.

Previously reconnect retry was not controlled and was repeated indefinitely.
This patch adds two options, ctrlr_loss_timeout_sec and reconnect_delay_sec,
to nvme_ctrlr and add reset_start_tsc, reconnect_is_delayed, and
reconnect_delay_timer to nvme_ctrlr to control reconnect retry.
Both of ctrlr_loss_timeout_sec and reconnect_delay_sec are initialized to
zero. This means reconnect is not throttled as we did before this patch.
A few more changes are added.
Change nvme_io_path_is_failed() to return false if reset is throttled
even if nvme_ctrlr is reseting or is to be reconnected.
spdk_nvme_ctrlr_reconnect_poll_async() may continue returning -EAGAIN
infinitely. To check out such exceptional case, use ctrlr_loss_timeout_sec.
Not only ctrlr reset but also non-multipath ctrlr failover is controlled.
So we need to include path failover into ctrlr reconnect.
When the active path is removed and switched to one of the alternative paths,
if ctrlr reconnect is scheduled, connecting to the alternative path is left
to the scheduled reconnect.
If reset or reconnect ctrlr is failed and the retry is scheduled,
switch the active path to one of alternative paths.
Restore unit test cases removed in the previous patches.

We noticed the difference between the SPDK 21.10 and the latest master
in a test.
The simplified scenario is as follows:
1. Start SPDK NVMe-oF target
2. Run bdevperf for the target with -f parameter to suppress exit
on failure.
3. Kill the target after I/O started.
With the SPDK 21.10, bdevperf retries failed I/Os and exits after
the test time is over.
With the latest SPDK master, bdevperf hungs and does not exit even
after the test time is over.
The cause was as follows:
reset ctrlr is repeated very quickly (once per 10ms by default) and hence
I/Os were queued infinitely because nvme_io_path_is_failed() returned
false if nvme_ctrlr is resetting.
We should queue I/O when nvme_ctrlr is resetting only if reset is throttoled
and fail-fast for the repeated failures is supported.
Hence in this patch, fix the degradation and remove the related unit
test cases.

This patch adds the framework for a discovery
service in the bdev/nvme module.
Users can specify an IP/port of a discovery service.
The bdev/nvme module will connect to a discovery
controller, get the discovery log page, and then
register for AERs. It will connect to each
subsystem specified in the initial log page.
AER completions will trigger fetching the log
page again, at which point new subsystems will
be connected to, or removed subsystems will be
detached.
This patch does the following:
* Adds the new start_discovery RPC
* Connects to the discovery controller
* Gets the discovery log page
* Registers for AERs
* Detach from discovery controllers at shutdown
Subsequent patches in this series will:
* Connect to subsystems listed in discovery log page
* Detach from subsystems that were listed in earlier
discovery log pages but subsequently removed
* Add a stop_discovery RPC

We set cb_ctx to NULL when calling spdk_nvme_probe_async(). It looks
that nvme_probe_ctx has not been used anywhere for a long time.
nvme_probe_ctx is not public data structure.

The failover_in_progress flag is used to decide the return value of
bdev_nvme_failover().
bdev_nvme_delete() calls bdev_nvme_failover() with remove=true to remove
nvme_ctrlr->active_path_id. However bdev_nvme_failover() returns zero
if nvme_ctrlr->failover_in_progress is true. bdev_nvme_failover() may
return zero even if it does not remove nvme_ctrlr->active_path_id.
The following will be better.
bdev_nvme_failover() returns -EBUSY if nvme_ctrlr->resetting is true,
and the caller repeats calling bdev_nvme_failover() until the target trid
becomes alternative path or bdev_nvme_failover() returns zero.
To do that, the failover_in_progress flag is not necessary any more.
Removing the failover_in_progress will also simplify the following
patches to unify ctrlr reset and failover.

When a I/O or admin passthrough failed, if the corresponding nvme_ctrlr
is not available, we should failover to another path.
When no path was found, if there is at least one nvme_ctrlr which is
not failed, we should wait until it is recovered.
We should improve error recovery not only for multipath (multipath is
"multipath") but also for failover (multipath is omitted or "failover").
To do this easily, clarify the conditions of availability and failure of
nvme_ctrlr and realize them by helper functions.
Use new helper functions for other cases to improve readability too.

We had not checked the bit 0 of the Namespace Multipath I/O and
Namespace Sharing Capabilities (NMIC) field in the Identify Namespace
data structure.
If the bit 0 of the NMIC is zero, it is likely that namespaces are not
identical.
We should check if the value of the NMIC first, and do it in this patch.
Additionally, it is not usual if the bit 0 of the CMIC and the bit 0 of
the NMIC do not match. So in unit tests rename the parameter multi_ctrlr
by multipath for ut_attach_ctrlr() and use it for the value of the NMIC.

bdev_nvme_reset() deletes all qpairs, reset a ctrlr, and then create
all qpairs. Any qpair may fail to be created, and then the reset
request may fail. However, already created qpairs were left.
Let's delete the already created qpairs and then fail the reset request.
This will make us easier to control reconnect, deley reconnect by
a few seconds, or stop reconnect after repeated failures and then
delete ctrlr.

Replace the spdk_nvme_ctrlr_reset_async() and spdk_nvme_reset_poll_async()
calls by the spdk_nvme_ctrlr_disconnect(), spdk_nvme_ctrlr_reconnect_async(),
and spdk_nvme_ctrlr_reconnect_poll_async() calls in a reset ctrlr
sequence.
spdk_nvme_ctrlr_disconnect() can fail if ctrlr is already resetting or
removed. But both cases are not possible. reset is controlled and the callback
to the hot remove is called when the ctrlr is hot removed. So we assume
spdk_nvme_ctrlr_disconnect() always succeed.

In the following patches, we want to retry reconnect if reconnect failed
in a reset ctrlr sequence but we want to delay the retry. While
we wait the delayed retry, we want to quiesce ctrlr completely.
As part of quiesce ctrlr operations, we want to pause adminq poller but
we need to do it on the nvme_ctrlr->thread.
If a reset ctrlr sequence runs on the nvme_ctrlr->thread, we can avoid
redirecting the pending destruct request at completion too.
So we redirect the reset ctrlr sequence into the nvme_ctrlr->thread.

When resetting ctrlr, adminq is disconnected first. If adminq is disconnected,
admin passthrough request is rejected with -ENXIO.
But resetting ctrlr may succeed. If resetting ctrlr succeeds, adminq is
connected again, and admin passthrough request will be
submitted successfully.
On the other hand, if ctrlr is failed, admin passthrough request is
rejected with -ENXIO. But when resetting ctrlr, ctrlr is set to unfailed.
Hence bdev_nvme_admin_passthru() skips any ctrlr which is resetting
or failed, and calls bdev_nvme_admin_passthru_complete() with -ENXIO
if no available ctrlr is found.
bdev_nvme_admin_passthru_complete() queues admin passthrough request
and retry it one second later if ctrlr is resetting.
