e64728f092 bdev/crypto: make sure that vbdev_crypto_destruct() returns 1
Make vbdev_crypto_destruct() return 1 to signal that program
execution should wait for spdk_bdev_destruct_done() function,
which is added inside _device_unregister_cb().

This change is related to _vdev_dev_get() not being able
to find the devices, when called from _cryptodev_sym_session_free(),
as it uses device driver name, which might already be freed.
This occurs only during bdev module finish, when crypto bdevs
are being unregistered and vbdev_crypto_finish() proceeds to
call bdev name deletion without waiting for the unregister
callbacks to complete, which ultimately results in reading
freed pointers.

This only happens when code execution takes path for DPDK 22.11+.

3878371ab2 bdev/crypto: Add new callback to spdk_bdev_unregister_bdev_by_name()
Currently delete_crypto_disk() calls spdk_bdev_unregister_bdev_by_name()
and immediately after exiting that function, it proceeds to bdev name
deletion. This causes callbacks triggered by above call to run with
references to bdev names that are partially unavailable due to free()
functions in vbdev_crypto_delete_name().

Add an intermediate callback that will call vbdev_crypto_delete_name()
and then the original callback that was sent as an argument to
delete_crypto_disk(). That way we are sure that bdev name deletion
is performed right after bdev unregister.

f61b004197 bdev_nvme: update nvme_io_path stat when IO completes
Currently we have stat per bdev I/O channel, but for NVMe bdev
multipath, we don't have stat per I/O path. Especially for
active-active mode, we may want to observe each path's statistics.

This patch support IO stat for nvme_io_path. Record each nvme_io_path
stat using structure spdk_bdev_io_stat.

The following is the comparison of bdevperf test.

Test on Arm server with the following basic configuration.
1 Null bdev: block size: 4K, num_blocks:16k
run bdevperf with io size=4k, qdepth=1/32/128, rw type=randwrite/mixed with 70% read/randread

Each time run 30 seconds, each item run for 16 times and get the average.

The result is as follows.

8f36853a84 dpdk_cryptodev: Check queue capacity before submitting a task
When we submit more tasks than supported by qp,
extra tasks are queued on io_channel. Later completion
poller tries to resubmit these tasks one by one. That
is not efficient since every enqueu_burst may cause
doorbell updates in HW.

Instead add a check for qpir capacity and submit
appropriate number of requests. If qpair is full,
tasks are queued in dedicated list. This approach
should remove or minimize the need to resubmit
individual crypto operations.

This also handles a case where there are no entries
in global pools (crypto_ops or rte_mbuf)

Fixes issue #2756

bf8e0656e8 dpdk_cryptodev: Remove limit on max IO size
Previously vbdev_crypto used DPDK directly and
the restriction on max IO size was propagated to
generic bdev layer which split big IO requests.

Now, when DPDK code is a standalone accel module,
this restriction on max IO size is not visible to
the user and we should get rid of it.

To remove this limitation, allow to submit crypto
operations for part of logical blocks in big IO,
the rest blocks will be processed when all submitted
crypto ops are completed.

To verify this patch, add a functional test which
submits big IO verify mode

957076108f accel: remove nbytes from spdk_accel_task
All operations are using iovecs to describe their buffers and only
encrypt/decrypt additionally used nbytes to store the total size of a
src buffer.  We don't really need this value in the generic accel code,
so we can let modules calculate it, if necessary.  That way, we won't
waste cycles calculating it if a module doesn't use it and it makes the
code a bit easier, as we won't have to deal with the fact that nbytes is
only valid for certain operations.

c22b052b60 bdev/raid0: Support resize when increasing the size of base bdevs
Implement the resize function for RAID0. raid0_resize() calculate the
new raid_bdev's block count and if it is different from the old block
count, call spdk_bdev_notify_blockcnt_change() with the new block count.

A raid0 bdev always opens all base bdevs. Hence, if the size of base
bdevs are reduced, resize fails now. This limitation will be removed
later.

Add a simple functional test for this feature. The test is to create
a raid0 bdev with two null bdevs, resize one null bdev, check if the
raid0 bdev is not resize, resize another null bdev, check if the raid0
bdev is resized.

test/iscsi_tgt/resize/resize.sh was used a reference to write the test.
Using jq rather than grep&sed is better and hence replace grep&sed by jq
of test/iscsi_tgt/resize/resize.sh together in this patch.

dee8e1f4c0 accel: use iovecs for copy operations
This patch is first in the series of patches aimed to make all accel
operations describe their buffers with iovecs.  The intention is to make
it easier to handle tasks in a generic way.

It doesn't mean that we change the API - all function signatures are
preserved.  If a function doesn't use iovecs, we use the aux_iovs array.
However, this does mean that each accel module that provides support for
a given operation will need to be adjusted to use iovecs.

Additionally, update the unit test checking copy elision to verify the
buffers of the copy operation that is left.

8346b57397 bdev/nvme: Unify _bdev_nvme_find_io_path() and bdev_nvme_find_next_io_path()
Unify _bdev_nvme_find_io_path() and bdev_nvme_find_next_io_path()
into _bdev_nvme_find_io_path() by modifying nvme_io_path_get_next().

For active/passive policy, _bdev_nvme_find_io_path() is called only if
nbdev_ch->current_io_path is NULL. Hence, the prev parameter is not
necessary anymore.

7baa78c86c bdev/nvme: Refactor _bdev_nvme_find_io_path() to cache non-optimized path for active/active
nbdev_ch->current_io_path is NULL at initialization.
bdev_nvme_find_io_path() calls _bdev_nvme_find_io_path() if
nbdev_ch->current_io_path is NULL. If there is no optimized path,
nbdev_ch->current_io_path is not filled. Hence, as long as there is no
optimized path, bdev_nvme_find_next_io_path() is never called.

However, bdev_nvme_find_next_io_path() fills nbdev_ch->current_io_path
even if the found path is non optimized.

This is a contradiction and a bug.

To fix this bug, as a preparation, refactor _bdev_nvme_find_io_path() to
cnosolidate bdev_nvme_find_next_io_path() and _bdev_nvme_find_io_path()
into a single function because  bdev_nvme_find_next_io_path() and
_bdev_nvme_find_io_path() were almost identical.

ae620784bd bdev/nvme: Retry I/O to the same path if error is I/O error
When an I/O gets an I/O error, the I/O path to which the I/O was
submitted may be still available. In this case, the I/O should be
retried to the same I/O path. However, a new I/O path was always
selected for an I/O retry.

For the active/passive policy, the same I/O path was selected naturally.
However, for the active/active policy, it was very likely that a
different I/O path was selected.

To use the same I/O path for an I/O retry, add a helper function
bdev_nvme_retry_io() into bdev_nvme_retry_ios() and replace
bdev_nvme_submit_request() by bdev_nvme_retry_io(). bdev_nvme_retry_io()
checks if nbdev_io->io_path is not NULL and is available. Then, call
_bdev_nvme_submit_request() if true, or call bdev_nvme_submit_request()
otherwise. For I/O path error, clear nbdev_io->io_path for
clarification. Add unit test to verify this change.

Linux kernel native NVMe multipath already takes this approach. Hence,
this change will be reasonable.

21160add26 bdev/nvme: Factor out request submit functions into a helper function
The following patches will change I/O retry to use the same io_path if
it is still available. However, bdev_nvme_submit_request() always calls
bdev_nvme_find_io_path() first. For I/O retry, if possible, we want to
skip calling bdev_nvme_find_io_path() and use nbdev_io->io_path instead.
To reuse the code as much as possible and not to touch the fast code
path, factor out request submit functions from
bdev_nvme_submit_request() into _bdev_nvme_submit_request().

While developing this patch, a bug/mismatch was found such that
bdev_io->internal.ch was different from ch of
bdev_nvme_submit_request(). Fix it together in this patch.

2796687d54 nvme: Added support for TP-8009, Auto-discovery of Discovery controllers for NVME initiator using mDNS using Avahi
Approach:
Avahi Daemon needs to be running to provide the mDNS server service. In the SPDK, Avahi-client library based client API is implemented.
The client API will connect to the Avahi-daemon and receive events for new discovery and removal of an existing discovery entry.

Following sets on new RPCs have been introduced.

scripts/rpc.py bdev_nvme_start_mdns_discovery -b cdc_auto -s _nvme-disc._tcp

User shall initiate an mDNS based discovery using this RPC. This will start a Avahi-client based poller
looking for new discovery events from the Avahi server. On a new discovery of the discovery controller,
the existing bdev_nvme_start_discovery API will be invoked with the trid of the discovery controller learnt.
This will enable automatic connection of the initiator to the subsystems discovered from the discovery controller.
Multiple mdns discovery instances can be run by specifying a unique bdev-prefix and a unique servicename to discover as parameters.

scripts/rpc.py bdev_nvme_stop_mdns_discovery -b cdc_auto

This will stop the Avahi poller that was started for the specified service.Internally bdev_nvme_stop_discovery
API will be invoked for each of the discovery controllers learnt automatically by this instance of mdns discovery service.
This will result in termination of connections to all the subsystems learnt by this mdns discovery instance.

scripts/rpc.py bdev_nvme_get_mdns_discovery_info

This RPC will display the list of mdns discovery instances running and the trid of the controllers discovered by these instances.

Test Result:

The new module replaces functionality in vbdev_crypto.
This module is bdev agnostic, so some inernal parts
were reworked.

io_channel: contains a qp of every configured DPDK PMD
crypto key: for mlx5_pci we register a key on each available

e33ae4a6d5 bdev/nvme: Count number of NVMe errors per type or code
Error counters for NVMe error was added in the generic bdev layer but
we want to know more detailed information for some use cases.

Add NVMe error counters per type and per code as module specific
statistics.

For status codes, the first idea was to have different named member
for each status code value. However, it was bad and too hard to test,
review, and maintain.

Instead, we have just two dimensional uint32_t arrays, and increment
one of these uint32_t values based on the status code type and status
code. Then, when dump the JSON, we use spdk_nvme_cpl_get_status_string()
and spdk_nvme_cpl_get_status_type_string().

This idea has one potential downside. This idea consumes 4 (types) *
256 (codes) * 4 (counter) = 4KB per NVMe bdev. We can make this smarter
if memory allocation is a problem. Hence we add an option
nvme_error_stat to enable this feature only if the user requests.

Additionally, the string returned by spdk_nvme_cpl_get_status_string()
or spdk_nvme_cpl_get_status_type_string() has uppercases, spaces, and
hyphens. These should not be included in JSON strings. Hence, convert
these via spdk_strcpy_replace().

d093a9fb85 bdev_xnvme: Remove duplicate invocation of bdev_xnvme_destruct
Fix for the issue 2803.
Reporting an error when deleting xnvme bdev.

bdev_xnvme_destruct gets invoked from the fn_table->destruct prior to
the xnvme_bdev_unregister_cb while deleting the xnvme bdev.

Hence removed the duplicate invocation of bdev_xnvme_destruct in
the function xnvme_bdev_unregister_cb.

Additionally, fixed the hang issue when the bdev_xnvme_delete
gets called multiple times for a xnvme bdev.
