This is the beginning of support for external snapshots. An external
snapshot is a read-only blobstore device (struct spdk_bs_dev) that can
be used as a blob's back device. Normally a blob will have no back
device (a normal blob), a zeroes back device (a thin provisioned blob),
or a blob back device (a clone blob). When a blob has an external
snapshot ("esnap") as its back device, it is called an esnap clone.
With this patch, esnap clones can be created but they are not yet

various features, and allow lvol bdevs to be esnap clones.

If a driver is registered and selected, it'll now be used to execute
sequences of accel operations. The driver has priority over accel
modules, so the modules will only be used to execute operations that the
driver cannot perform.
Once driver completes a task (or a number of tasks), it notifies accel
using standard spdk_accel_task_complete(). To let accel continue
processing a sequence, driver can call spdk_accel_sequence_continue().
This can be done when the driver executes all tasks (1), an error occurs
(2), or the driver doesn't know how to execute a given opcode (3). In
case of (3), that operation will be executed using appropriate accel
module and, while the rest of the sequence will be sent back to the
driver.

Depending on the number of cores there are sporadic issues getting
elements of that pool although free elements are there during poll
group creation. Operation returns -ENOBUF. It results in odd notice
msg.
"nvmf_transport_poll_group_create: *NOTICE*: Unable to reserve the
full number of buffers for the pg buffer cache. Decrease the number of
cached buffers from 455 to 1366"
In this case 1366 is the actual number of available elements in the
pool. Few poll groups suceeds and few are ending up with the buffer
cache size set to 0.
Issue has been rootcaused as bug or behaviour change in DPDK v22.01.
Consider example:
We create DPDK mempool with 4K buffers, cache of 256. When first poll
group requests 512 buffers, DPDK mempool first looks in its per-core
cache, sees no buffers (mempool buffer cache doesn't get prepopulated)
and then requests 512 + 256 buffers from the backing pool. It returns
512 of the buffers to the user, and puts the other 256 buffers in the
cache ...it should only request 512 buffers total. For 8 cores and 512
buffers requested only 5 cores will get their buffers.
Disabling mempool cache seems to workaround the issue. More effective
cache is already implemented on nvmf generic layer.

The spdk_bdev_ext_io_opts structure is used to pass extra options when
submitting a bdev IO request, without having to modify/add functions to
handle new options. Additionally, the structure has a size field to
allow adding new fields without breaking the ABI (and thus having to
bump up the major version of a library).
It is also a part of spdk_bdev_io and there are several reasons for
removing it from that structure:
1. The size field only makes sense in structures that are passed
through pointers. And spdk_bdev_ext_io_opts is indeed passed as a
pointer to spdk_bdev_{readv,writev}_blocks_ext(), however it is
also embedded in spdk_bdev_io (internal.ext_opts_copy), which is
also part of the API. It means that each time a new field is added
to spdk_bdev_ext_io_opts, the size of spdk_bdev_io will also
change, so we will need to bump the major version of libspdk_bdev
anyway, thus making spdk_bdev_ext_io_opts.size useless.
2. The size field also makes internal.ext_opts cumbersome to use, as
each time one of its fields is accessed, we need to check the size.
Currently the code doesn't do that, because all of the existing
spdk_bdev_ext_io_opts fields were present when this structure was
initially introduced, but we'd need to do check the size before
accessing any new fields.
3. spdk_bdev_ext_io_opts has a metadata field, while spdk_bdev_io
already has u.bdev.md_buf, which means that we store the same thing
in several different places in spdk_bdev_io (u.bdev.md_buf,
u.bdev.ext_opts->metadata, internal.ext_opts->metadata).
Therefore, this patch removes all references to spdk_bdev_ext_io_opts
from spdk_bdev_io and replaces them with fields (memory_domain,
memory_domain_ctx) that were missing in spdk_bdev_io. Unfortunately,
this change breaks the API and requires changes in bdev modules that
supported spdk_bdev_io.u.bdev.ext_opts.

The goal of a platform driver is to execute chained accel operations in
the most efficient way possible. A driver is aware of the hardware
available on a platform and can execute several operations as a single
one. For instance, if we want to do DMA and then encrypt the data, the
driver can do both at the same time, if the hardware is capable of doing
that.
Platform drivers aren't required to support all operations. If a given
operation cannot be executed, the driver should notify accel to continue
processing a sequence, via spdk_accel_sequence_continue(), and that
operation will processed by a module assigned to its opcode.
It is required however, that all platform drivers support memory
domains, including the "virtual" accel domain. A method for allocating
those buffers will be added in the following patches.
This patch only adds methods to register and select platorm drivers, but
doesn't change the way a sequnce is executed (i.e. it doesn't use the
driver to execute it).

It is possible for requests waiting for R2T ACK to receive H2C PDU
before receiving the ACK. Therefore, the following sequence:
1. Host sends a write request to the target.
2. Target sends R2T PDU to the host and sets request's state to
AWAITING_R2T_ACK.
3. Host sends H2C PDU to the target, but it doesn't reach the target
yet.
3. Host sends an abort command to abort that request. Request's state
is changed to READY_TO_COMPLETE.
4. Target receives the H2C PDU, sees that request's state is
READY_TO_COMPLETE, which is unexpected, and terminates the
connection.
will cause the target to terminate the connection, which is obviously
incorrect.
So, to avoid that, we can treat AWAITING_R2T_ACK state in the same way
as TRANSFERRING_HOST_TO_CONTROLLER and register a poller waiting for the
state to be changed.

During secondary process shutdown, when nvme device
would get detached, it would trigger env_dpdk to
send rte_eal_hotplug_remove event for the corresponding
BDF. But this isn't valid from a secondary process -
we can only attach/detach from the primary process.
Usually this would just result in a bunch of annoying
print messages as the secondary and primary process
sent rte messages between each other. But occasionally
one of the response messages from the primary process
could arrive just as the secondary process was going
through rte_eal_cleanup. The message would get
kicked to the DPDK intr thread, we would do bus_cleanup
which frees all of the PCI state, and then the message
would execute on the intr thread causing seg faults,
use-after-free or some other violation.
It's possible some kind of cleanup should be
implemented in DPDK, but for now, let's just not
induce incorrect behavior from SPDK, and don't send
the hotplug_remove messages from a secondary
process.

Supporting SRQ caused two kinds of memory leaks. Fix both in this patch.
1. rqpair->rsps was leaked and null pointer access occurred
An error was detected during the nightly nvmf_delete_subsystem test.
The NVMe perf tool crashed with SIGABRT.
The reason of the crash was
nvme_rdma.c:2504:2: runtime error: member access within null pointer of type 'struct nvme_rdma_rsps'
This was caused by clearing rqpair->rsps before freeing rqpair->rsps.
rqpair->rsps should have been held until rqpair->rsps is freed. However,
when we support SRQ, rqpair->rsps was cleared when releasing rqpair->poller
by mistake. rqpair->rsps should be cleared only if SRQ is enabled because
in this case rqpair uses rsps of rqpair->poller.
2. rqpair->reqs and rsps are leaked for admin qpair at controller reset
To avoid unnecessary alloc and free for rqpair->rsps when enabling SRQ,
nvme_rdma_create_reqs() and nvme_rdma_create_rsps() were moved to
nvme_rdma_connect_established().
On the other hand, nvme_rdma_free_reqs() and nvme_rdma_free_rsps() were
called by nvme_rdma_ctrlr_delete_io_qpair().
However, at controller reset, admin qpair was just disconnected and
reconnected. In this case, nvme_rdma_create_reqs() and
nvme_rdma_create_rsps() were called again without calling
nvme_rdma_free_reqs() and nvme_rdma_free_rsps().
Hence, memory leak occurred.
To fix the memory leak, move nvme_rdma_free_reqs() and nvme_rdma_free_rsps()
from nvme_rdma_ctrlr_delete_io_qpair() to nvme_rdma_qpair_destroy().

When a queue has finished processing on its polling
thread, it sends a message to the app thread signaling
that it is done. Then when the app thread gets
messages from all of the queues for that device, it can
proceed with tearing the device down.
But if there are still ctrl_ring commands in progress,
it needs to wait. Previously it would register a
poller that would retry the same function if it
found commands in progress. But the problem is that
it did not differentiate the function getting called
as a direct message from the polling thread vs. retried
via the poller on the app thread. This could result
in lost messages.
So fix it to always increment the queues_closed
counter (renamed from q_deinit_num), and then
only check for ctrl ring commands in progress after
we received all of the queue closed messages.

There is a way to pause/resume spdk pollers, however there is no way
to achieve that using public API for the given target which has
a hook behaving similar to pollers. Exposing such functionality can
be used for pausing and restoring target pollers during
reset, e.g. new commands should not be fetched to assure
that all internal resources can be cleared/reinitialized safety.
Pausing target poller during the reset will assure that, without
need for destroying transport or adding condition statements in IO path.
Similar use case might be hitless upgrade. Depending on implementation
there might be need that no new command can be submitted when
secondary processes are being switched to upgraded versions.
Pausing target pollers should be useful in this case.

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 23.05
release.
Looks like this was left over from prior LTS, to avoid that
make sure it is only skipped when running against v23.01.x as latest
release.
This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests
Short reference to how the versions were changed:
MAX=$(git grep "SO_VER := " | cut -d" " -f 3 | sort -ubnr | head -1)
for((i=$MAX;i>0;i-=1)); do find . -name "Makefile" -exec \

With per channel stats called on thread A,
spdk_bdev_for_each_channel calls
spdk_for_each_channel which immediately sends
a message to thread B.
If thread B has no workload, it may execute the
message relatively fast trying to write stats to
json_write_ctx.
As result, we may have 2 scenarious:
1. json_write_ctx is still not initialized on
thread A, so thread B dereferences a NULL pointer.
1. json_write_ctx is initialized but thread A writes
response header while thread B writes stats - it leads
to corrupted json response.
To fix this race condition, initialize json_write_ctx
before iterating bdevs/channels

When blobstore is shutdown unexpectedly the super block should
already be marked as dirty. Only when proper blobstore unload
happens, the super block is marked as clean.
Super block is not marked as dirty on blobstore load,
but on first action that starts to modify the metadata.
At this time it only happens through blob persist,
which is fine for creation/deletion of blobs or
their modification (resize/xattr).
It works for cluster allocation with extent_table disabled,
and when extent page needs to be allocated.
Yet it fails for cases when no new extent page is required.
It will result in not marking blobstore as dirty and
then fail when loading a particular blob due to mismatch
between used_clusters and contents of extent page.
To fix that, the blobstore is now marked dirty on a very first
extent page update since blobstore load.

gcc-12 is really tricky. It detected that in
ftl_nv_cache_load_state() that when we do an FTL_NOTICELOG,
the dev and nv_cache values are associated with each
other by the SPDK_CONTAINEROF() operation.
So then in FTL_LOG_COMMON, it checks if dev is NULL. If it
is, it doesn't print the dev->conf.name, but still prints
the varargs which include nv_cache members. But if dev is
NULL then these nv_cache members wouldn't be valid either,
and that's what gcc-12 is complaining about, in a very
unclear way.
So now we just have FTL_LOG_COMMON contain a single line, with
a tertiary operator to print either dev->conf.name or "N/A"
depending on whether dev is NULL or not. I suspect this
fixes it because we've replaced the if statement with
a tertiary operator that is independent from the VA_ARGS.
Fixes issue #2829 (partially).

This is the port of the vbdev compress logic into the accel
framework. It includes just one enhancement, to only fill each
mbuf in either src or dst array with max "window size" param to
avoid QAT errors. Note that DPDK ISAL PMD was not ported as we
have native ISAL compression in accel now.
Note: ISAL w/DPDK is still built w/this patch, that can't be
removed until the vbdev module moves to accel fw as it still
depends on DPDK ISAL PMD.
Follow-on patches will include addition C API for PMD selection,
this patch just gets equivalent functionality going. Upcoming
patches will also convert the vbdev compress module to use the
accel framework instead of talking directly to compressdev.
More patches will also address comments on vbdev common code
that addressed here would make the review challenging.
This patch also fixes a bug in the ported code that needs to
be fixed here to pass CI. Capability discovery was incorrect
causing all devices to appear to not support chained mbufs,
with the mbuf splitting code this is important to get right.
