bcb75753dc bdev/nvme: add DISCOVERY_DEBUGLOG/ERRLOG
These macros are used to prefix the following to
any discovery-related DEBUGLOG or ERRLOG:

Discovery[127.0.0.1:8009]

Inside the brackets are the traddr and trsvcid of
the discovery service associated with that message.

9614dca9f9 bdev/nvme: save the trid of the discovery service
This is useful for adding trid details to discovery
related log messages in a later patch.

Future patches will update this trid if the
current discovery ctrlr fails and we need to fail
over to a different path to the discovery subsystem.

5f27092835 thread: add spdk_thread_exec_msg()
A common pattern is:

	if (foo->thread == spdk_get_thread())
		cb(arg);
	else
		spdk_thread_send_msg(foo->thread, cb, arg);

for cases where it's important the callback runs on a particular thread,
but it doesn't matter if it's synchronous or asynchronous.

Add a new API to support this pattern, and convert over the current
instances.

79829ae40b bdev/nvme: Set ana_state_updating only after starting read ANA log page
In a test case, test/nvmf/host/failover.sh, we got ANA error even if
the target did not enable ANA reporting.

We marked the corresponding namespace as ANA state updating but we had
no way to clear it.

Check if we can read ANA log page before setting the flag.

If read ANA log page failed, disable ANA feature until the nvme_ctrlr
is created again. In this operation, all ana_state_updating flags are
cleared.

Fixes #2335

f36c033c71 uring: fix bug when inserting sock into pending_recv list
There is io error when running NVMe over TCP fio test with uring
socket. It's easy to reproduce the bug with the following
configuration:
target 1 core, 16NVMe SSD, 2 initiators each connects to 8 NVMe
namespaces, each runs fio with numjobs=3.

For if in each round, we inset the sock to the head of the
pending_recv list, and then get max_events socks from head of the
list to process, there is possibility that some socks are always
not processed.
Although there was a strategy to cycle the pending_recv list to make
sure we poll things not in the same order. Such as a list: A B C D E F,
if max_events is 3, then this strategy makes the list is rearranged to
D E F A B C. But it will make this strategy not effective if using
TAILQ_INSERT_HEAD(&group->pending_recv, sock...).

Using TAILQ_INSERT_TAIL(&group->pending_recv, sock...) can fix it.

047c067c05 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the future releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 22.05
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

Starting with DPDK 21.11 QAT_SYM and QAT_ASYM were

As vbdev_crypto didn't make use of it,
this driver is now skipped in preparation for

destroyes nvmf_tgt. Part of nvmf_tgt destruction is
destruction of subsystems and this process may require
cross thread communication but since poll groups and
threads are already destroyed, we may get segfaults.

One possible solution is to change the order and destroy
nvmf_tgt before destroying poll groups but it doesn't
work since nvmf_tgt is registered as io_device and
poll groups have its channel, so it can't be destroyed
while poll groups exist.

This patch adds a new state to nvmf_tgt state machine
which destroys all subsystems before destroying poll
groups and nvmf_tgt. It guarantees that all threads
exist when subsystems are destroyed.

Also rename state NVMF_TGT_FINI_FREE_RESOURCES to
NVMF_TGT_FINI_DESTROY_TARGET, the new name better
reflects the purpose of this state.

6b7e9d0af2 Lib/iSCSI: add the LUN Resize support
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.

80e81273e2 bdev/nvme: Do not use ctrlr for I/O submission if reconnect failed repeatedly
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.

ae4e54fdc3 bdev/nvme: Retry reconnecting ctrlr after seconds if reset failed
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.

962c4c3800 bdev/nvme: Fix a degradation that I/O gets queued infinitely
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.

Requests that are completed immediately (i.e. those not using the accel
engine) are now queued and their completion is delayed to the completion
poller.  It ensures that they're not completed from the context of a
submission, which gets rid of an spdk_thread_send_msg() call.

It significantly improves performance on some workloads.  For instance,
4k zcopy reads (queue depth 128) on an malloc bdev exposed through
NVMe/TCP went from 204k IOPS to 485k IOPS.

d1024c4bc6 bdev/delay: zero-copy support
This patch adds support for zero-copy operations in the delay bdev.
They use the same delay values as regular IO operations:
 - (avg|p99)_read_latency for zcopy_start with populate=true,
 - (avg|p99)_write_latency for zcopy_end with commit=true.

All other zcopy operations (e.g. zcopy_start with populate=false) are
not delayed.

I/O path cache should be cleared and the path should be chosen as the
optimal path.

This bug was found by a system test.
