The NVMe bdev module will have two similar features, multipath and
failover when it supports multipath.
Take a case that we add two different trids with the same name by the
bdev_nvme_attach_controller RPC as an example.
The failover adds secondary trid to an existing nvme_ctrlr. The multipath
feature creates another nvme_ctrlr and adds it to the same nvme_bdev_ctrlr
which has an existing nvme_ctrlr.
We want to use bdev_nvme_attach_controller for both failover and multipath.
To do it cleanly, separate callback to spdk_nvme_connect_async() between
creating ctrlr and setting failover.

When a bdev is being unregistered, after all
channels have been closed, the bdev layer calls
the module's destruct callback for the bdev before
calling the bdev unregister callback.
For the rbd module, the destruct callback is
bdev_rbd_destruct. This callback unregisters the
rbd io_device which is an asynchronous operation.
We need to return >0 from bdev_rbd_destruct to
inform the bdev layer that this is an asynchronous
operation, so that it does not immediately call
the bdev unregister callback. Once the rbd io_device
is unregistered, we can call spdk_bdev_destruct_done()
which will trigger the bdev layer to finally call
the bdev unregister callback.
Without this fix, deleting an rbd bdev would
complete before the backing cluster reference
had been released. This meant that even
if you had deleted all rbd bdevs, there might still
be cluster references in place for a short period of
time. It's better to wait to complete the delete
operation until the cluster reference has been
released to avoid this issue (which this patch
now does).
Fixes issue #2069.

The bdev layer doesn't call the destruct callback until
all channels have been released, but because the channel
delete callback passes message to the main thread, we can
end up with a complicated race condition. Currently we
have a deferred_free code path to handle this race, but
we can handle this a bit more cleanly by doing the
construct operation on the main_td as well.
This also simplifies the next patch which will
asynchronously destruct the bdev to fix an RPC bug.
Here's the race:
1) first channel was created on thread A, so disk->main_td = thread A
2) second channel was created on thread B
3) first channel is freed (but disk->main_td is still thread A)
4) spdk_bdev_unregister is called on thread C
5) bdev layer gives callback on thread B to upper layer
6) upper layer on thread B frees channel
7) bdev_rbd_destroy_cb runs on thread B and has to send msg to thread A
for processing
8) bdev layer calls bdev_rbd_destruct on thread C (since step #4 was on
thread C)

Once bdev finish starts, bdev unregister is called on all
unclaimed bdevs. This means that for lvs with at least one
lvol present, there will be a corresponding bdev unregister.
Yet the vbdev_lvol module does not attempt to unload the lvs,
once last lvol from that lvs is unregistered. Leaving
the base bdev for lvs claimed.
This patch fixes that by using fini_start callback from
bdev_module to mark when shutdown begins. After that
last lvol unregistered on lvs will unload it.
Expanded struct lvol_bdev to contain lvol_store_bdev.
Closing the lvol will free spdk_lvol, so lvol->lvol_store cannot
be accessed.
Changed ut_lvol_destroy UT to ut_bdev_finish. Previous UT didn't
really test vbdev_lvol_destroy, but 'hotremove' of the lvol bdev.
In effect there is no hotremove of the lvol bdevs (only lvs bdev).
spdk_bdev_unregister() can only be called from within vbdev_lvol,
or during bdev module finish.
This UT will now check the bdev module finish.
Note that at this point lvs with no lvols will not trigger
lvs unload. Next patches in series will introduce async fini_start,
to allow for the unload.

We need to ensure that cache's bdev block size is not bigger than

smaller than cache device's block size.
The reason why this is implemented late in the cache start and not
as soon as we want to construct OCF vbdev is that cache or core
device can be added later after OCF vbdev creation and only then
we are certain to have both devices to compare.

nvme_ctrlr will be registered as io_device even when multipath is
supported. Hence while spdk_for_each_channel() is executed in reset
processing, we can get nvme_ctrlr both spdk_io_channel_iter_get_ctx()
and spdk_io_channel_iter_get_io_device(). This duplication is not
necessary. Use spdk_io_channel_iter_get_io_device() and pass NULL

bdev_nvme_submit_request() basically passes nvme_bdev_io to each I/O

Previously only a single thread could submit abort commands for admin
commands and it was the thread of the corresponding controller.
When we support multipath, we need to traverse the list of controllers
to which the target admin command is submitted. Threads of controllers
may be different.
On the other hand, the previous implementation made the I/O flow very
clean, but the I/O flow will not be clean if there are many controllers
and the subsystem does not have its thread.
This patch changes the policy so that any SPDK thread can submit abort
commands for admin commands.
Then when multipath is supported, we will be able to traverse the
list of controllers simply on the current thread to abort either I/O
command or admin command.
We already are able to submit any admin command on any thread anytime
including abort command. Hence this will not cause any issue.

When multipath is supported, a subsystem has multiple controllers and
bdev_nvme_create_cb() will create a channel per nvme_bdev_ctrlr by
iterating the list of nvme_bdev_ctrlrs, and will hold lock while
doing it.
If the code to access nvme_bdev_ctrlr is put in a place, the
following patches will be easier and smaller.
Hence reorder the code of bdev_nvme_create_cb() as a preparation.

Recently, checked the spdk_io_device_unregister function,
it will have deferred free behaviour, and the io_device
will possibly be freed in put_io_channel function.
And this means that it is not safe to directly call:
spdk_io_device_unregister (io_device, NULL);
Then free io_device relately resource.
Because there will be channel to use the resources associated
with io_device. Then we will possibly cause a NULL pointer access.
I found this issue in bdev rbd module, and I think that the
same issue could happen in other modules. So it is better to put the
resource free function as the call back function.

We cannot rely on DSM/DEALLOCATE as a write zeroes
alternative, even if DLFEAT reports that deallocated
blocks will be read as all zeroes. DEALLOCATE is
advisory, meaning that blocks may not actually be
deallocated. In cases where they are not deallocated,
they will not be read back later as zeroes.
QEMU 6.0 started reporting DLFEAT as returning zeroes
for deallocated blocks but for some of our write
zeroes tests, blocks aren't actually deallocated.
We may be able to add quirks in the future if we know
that a controller reliably deallocates blocks, but
for now we need to revert this completely.
Note that since bdev/nvme module now does not support
write zeroes in any cases, we need to disable the
write zeroes call in the unit tests.

first is for populating namespace and second is for nvme_bdev.

The following patches will remove nvme_ns->ref and use nvme_ns->populated
and nvme_ns->bdev instead because nvms_ns->ref is two at most and
each count of nvme_ns->ref corresponds to nvme_ns->populated or
nvme_ns->bdev.
To do that, we need to ensure nvme_ns->populated is cleared after
spdk_bdev_unregister() is called, otherwise nvme_bdev_ctrlr_destruct()
is called twice.
However OCSSD namespace had used nvme_ns->populated to free resource
after getting log page completes.
To keep such deferral, add the depopulate_pending flag to struct bdev_ocssd_ns
and use it. Then clear nvme_ns->populated in bdev_ocssd_free_namespace()
after spdk_bdev_unregister().

The nvme_ns->ref was added to nvme_bdev_ns to support both multipath
and OCSSD range. OCSSD range was to split a namespace into multiple
partitions.
However, OCSSD range was not used and removed to simplify multipath.
When namespace is not split, nvme_ns->ref is 2 at the maximum. First is
for populating namespace and second is for nvme_bdev. nvme_ns->populated
is for populating namespace and nvme_ns->bdev is for nvme_bdev.
Hence we can use nvme_ns->populated and nvme_ns->bdev directly instead of
nvme_ns->ref.
A few patches from this remove nvme_ns->ref and use nvme_ns->populated
and nvme_ns->bdev instead.
dThis patch inlines nvme_bdev_ns_detach() into the callers and remove it.
The following patches will adjust the locations to update nvme_ns->populated
and nvme_ns->bdev and then remove nvme_ns->ref.
Removing nvme_ns->ref will be helpful to associate multiple namespaces
into a single nvme_bdev for multipath.

Add support for zoned namespaces in the bdev/nvme module.
Query the namespace type, and if a zoned namespace is found, set the
bdev struct members needed by the bdev_zone.h APIs.
Note that while vbdev_zone_block and bdev_ocssd have zone locks,
bdev/nvme does not need any kind of zone lock, because NVMe ZNS
supports append natively.
The whole point of the zone append command is that you don't need any
locks, even when having multiple writers, since the drive will return
back the Assigned LBA where the blocks were actually written.
If a SPDK application will utilize writes instead of zone appends,
the SPDK application itself will need a per zone lock in order to
make sure that there is only one outstanding write.
Adding zone locks in bdev/nvme would reduce the performance of zone
appends, for no reason at all.

nvme_bdev_ctrlr is valid while populating namespaces of the
nvme_bdev_ctrlr regardless of the result. nvme_bdev_ns holds
nvme_bdev_ctrlr by its pointer, ctrlr. Hence it is not necessary for
nvme_ctrlr_populate_namespaces_done() to use nvme_bdev_ctrlr_get_by_name()
to get nvme_bdev_ctrlr.
To simplify the code, add nvme_bdev_ctrlr parameter to
nvme_ctrlr_populate_namespaces_done() and remove the
nvme_bdev_ctrlr_get_by_name() call from nvme_ctrlr_populate_namespaces_done().

In nvme_bdev_ctrlr_create, calloc will be called with a zero size
allocation request if the number of namespaces is zero. The behaviour
is implementation defined if the size of the space requested is zero -
calloc will either return a pointer that mustn't be dereferenced, or
NULL. If NULL is returned, the nvme_bdev_ctrlr_create will fail.
Only call calloc if there are a non-zero number of namespaces.
Otherwise, leave the namespaces pointer with a NULL value. All
references to namespaces[] are either known to be safe, or occur
in the context of looping through the namespaces which will be
skipped if the count is zero. The exception to this is in
vbdev_opal_create, where an assert has been added to match
equivalent code in bdev_ocssd_create_bdev.
Tested by running unit tests on a system that returns a null pointer
for a zero size allocation.

This patch changes the common and standard namespace specific

Add a particular error case that nvme_bdev is failed to create even
if ctrlr has one namespace. If ctrlr has one namespace but the
corresponding bdev is failed to create, nvme_ns->populated should
be false and hence nvme_ns->bdevs should not be accessed. However
the code had not assumed such 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 quarterly 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 21.04
release.
This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

When we do detect new devices, we would like to get them
attached as quickly as possible. Controller initialization
requires a non-trivial number of admin commands, and when
using async probe, it means that after we have detected
a new device, it will take many iterations of calling
spdk_nvme_probe_poll_async() before the controller is
fully attached.
So when we are actively probing a probe_ctx, create
a new poller that is solely responsible for probing
that context at a much higher frequency.

bdev_nvme_submit_request() calls bdev_nvme_get_buf_cb() directly
when the buffer is already allocated. This is for performance improvement
but will be helpful for the upcoming multipath feature to retry
read I/O submission because buffer should be allocated only once.
By reading the code a little more critically, bdev_nvme_submit_request()
can call bdev_nvme_readv() directly in this case, and do in this patch.

nvme_bdev_ctrlr pointer is already cached to nvme_io_channel.
Hence let's remove it from the helper functions, bdev_nvme_create_qpair()
and bdev_nvme_destroy_qpair().
The following minor fixes are done together in this patch.
Fix the error paths of bdev_nvme_create_qpair() because
bdev_nvme_destroy_qpair() cannot be used as is in this case.
When calling bdev_ocssd_destroy_io_channel(), check if nvme_ch->ocssd_ch
is not NULL instead of spdk_nvme_ctrlr_is_ocssd_supported().
Cache nvme_bdev_ctrlr to nvme_io_channel just before calling
bdev_nvme_create_qpair() because the pointer is more associated
with qpair.

When a device is removed, we should use the remove_cb
that was specified when the device was originally probed
and attached, if one was set.
Also add a new spdk_nvme_ctrlr_set_remove_cb API. This
can be used for cases where a different remove_ctx is
desired than was specified for the probe call. This
also enables setting a remove_cb when using connect APIs
which do not have a way currently to provide a remove_cb.
This also requires fixing the bdev nvme module, which
was depending on the previously errant behavior.

It is recommended to read CSTS when there is a timeout.
If CSTS.CFS (Controller Fatal Status) is set, we should
reset the controller.
But if an admin command on a fabrics controller times
out, reading CSTS submits another fabrics command that

This is very clean because spdk_bdev_io is processed by the generic bdev

The patch series changes ocssd_bdev to pass not spdk_bdev_io but

This patch is the first of the series and add ocssd_bdev parameter

Checking if destruct is false and setting destruct to true are
separated by mutex in remove_cb() and bdev_nvme_library_fini().
It was possible that multiple threads called nvme_bdev_ctrlr_destruct()
because the caller could call nvme_bdev_ctrlr_destruct() before
setting destruct to true after knowing it was false.
This patch ensures that nvme_bdev_ctrlr_destruct() is called only once.
Set ctrlr->destruct to true without releasing mutex after checking
if ctrlr->destruct is false.
If destruct is set to true before calling nvme_ctrlr_depopulate_namespaces(),
nvme_ctrlr_depopulate_namespace_done() may call nvme_bdev_ctrlr_destruct()
because it is likely that reference count is zero and destruct is true.
In this case, remove_cb() or bdev_nvme_library_fini() cannot call
nvme_bdev_destruct() after returning from nvme_ctrlr_depopulate_namespaces().
On the other hand, if a controller has no namespace,
nvme_ctrlr_depopulate_namespaces() does nothing and
nvme_ctrlr_depopulate_namespace_done() is not called. Hence
remove_cb() or bdev_nvme_library_fini() has to call nvme_bdev_destruct()
after returning nvme_ctrlr_depopulate_namespaces().
To unify both cases, initialize reference count to one as a sentinel value
and remove_cb() and bdev_nvme_library_fini() decrement reference count
and then calls nvme_bdev_ctrlr_destruct() if reference count is zero
after returning from nvme_ctrlr_depopulate_namespaces().
Additionally, add assert to check if reference count is not negative
to find bug in future.

Most of the options through the legacy config are already reflected in JSON.
Exception to that is "[VirtioPci] Enable" option, which worked for virtio_blk
and virtio_scsi. It then on initialization scanned virtio_pci devices for
presence of blk/scsi. There is no RPC that scans it on demand, nor was it used
in any of the tests. So this patch removes that functionality,
if needed this can be reintroduced as new RPC (or two for each backend).

Note that malloc_disk_count needs to be reset for each module initialization.

_bdev_nvme_submit_request() already has a pointer to nvme_io_channel.
Passing nvme_io_channel simply to I/O APIs will be reasonable
simplification.
Two admin APIs, bdev_nvme_abort() and bdev_nvme_admin_passthru()
get the associated thread to the spdk_io_channel and set it to
nvme_bdev_io. These APIs get spdk_io_channal from nvme_io_channel using
the container_of macro. These APIs are not performance sensitive.
Using the contaier_of macro will be better than extracting the operation
from these APIs because we can keep the changes local to these APIs.

Struct nvme_bdev has a pointer to nvme_bdev_ctrlr and a pointer to
nvme_bdev_ns now, but nvme_bdev_ctrlr can be accessed via
nvme_bdev->nvme_ns->ctrlr, and so nvme_bdev->nvme_bdev_ctrlr is
duplicated.
The upcoming multipath feature will need struct nvme_bdev to have
multiple nvme_bdev_ns pointers.
Hence remove nvme_bdev_ctrlr from struct nvme_bdev and get a pointer
to nvme_bdev_ctrlr from nvme_bdev->nvme_ns->ctrlr.

The bdev layer nicely handles the case where we call this

immediately calls the get_buf_cb. But this adds extra

Since nvme has no alignment restrictions, we can just
check the iovs directly and avoid the extra call to
spdk_bdev_io_get_buf when possible.

It aims to avoid bdev starvation by setting separate
io_context to each bdev_aio io channel and link them
into group channel.
Previous, each ch of aio_bdev on a same spdk_thread shares
same io_context. If one of them submits too many IO to the
io_context, then other channels will be starved.
Moreover, if the first bdev_io gets NOMEM error, then the
following IO of this bdev have no chance to get processed.
The bdev_aio starvation can be reproduced by bdevperf in
v20.04, by:
./bdevperf -q 100 -w randwrite -t 5 -c hdd.conf -o 1048576
(hdd.conf defines 2 aio_bdevs of HDD)

Fixes#1498
When shutting down the application, it was possible to
reference stale ocf_cache pointer. This was the case
when two or more vbdev_ocf devices were based on top
of single cache bdev.
This issue did not occur outside of the shutdown case,
since RPC only allows deletion of the vbdev_ocf.
This erases on disk metadata and next run of the application,
would not detect such vbdev_ocf.
Shutdown meanwhile works different, by first stopping
the instance of running "ocf_mngt_cache" and later detaching
"core" devices (the ones being cached). This prevented
erasing the on disk metadata and allowed for restarted
application to detect vbdev_ocf.
See patch (1292ef2) for details.
Since references to ocf_cache are copied between vbdev_ocf
[see start_cache()], the reference count inside ocf_cache
was limited to original ocf_mngt_cache_start() and
management queue creation. First call into ocf_mngt_cache_stop()
released all references to ocf_cache. Leaving other
vbdev_ocfs pointing to released memory.
This patch works around this issue by increasing ref cnt
on ocf_cache for each vbdev based on top of it.
It allows to call into ocf_mngt_cache_stop(), but not
release the memory for ocf_cache until last vbdev.
Note:
A proper redesign here is in order:
- either rearranging structures to be based around single ocf_cache,
rather than multiple vbdev_ocf instances
- better use of OCF API to reduce book keeping logic in vbdev
There are plans to implement detach/attach in RPC,
so it should be a focus during that effort.

There are additional conditions which SPDK tracks,
that are known before issuing call to OCF.
Two main ones are:
- if vbdev->ocf_cache was not yet created [start_cache()]
- if the cache bdev was opened [attach_base()]
Both happen for the first cache bdev once. Then for
consecutive vbdev_ocf on same cache bdev, reference
will be copied.
This call will simplify checking both conditions.
Calling into OCF with NULL or stale ocf_cache pointer,
rightly so will cause issues with ASAN.

This was sort of a clunky interface requiring a couple of inline
functions in every app that wants to use the accel_fw moving
forward. By having the accel_fw public API accept a callback arg
instead of an accel_task combined with adding a pool of accel_tasks
in the accel_fw engine we can eliminate this.
After changing the parm to a cb_arg, changes were made to all accel_fw
interfaces to put cb_fn and cb_arg as the last parms in public and
private function calls.
Related bdev_malloc changes need to be in this patch in order to pass CI.

Bdev underneath lvs has a certain value set as block size,
then lvolstore inherits that as `io_unit_size`,
which ends up as block size for the lvol bdev presents.
Before this patch lvs on device with block size of 512,
would create lvol bdev with block size of 512.
Meanwhile reporting in bdev_lvol_get_lvstores(),
that block_size is 4k instead.
This was result of addition of io_unit_size and
forgetting to update the value here. Previously
only I/O of page_size was allowed.
This patch adjusts the value reported to
io_unit_size.
Alternatively it could have been removed,
or name changed to "io_unit_size".
Yet for API compatibility reason this name
remains.
Info on actual page size which is always 4k,
is not useful to bdev users. No need to add
another field for that.

Use logical block size instead of base bdev block size in
vbdev_compress_claim. This is relevant to enable the compress bdev to
present a logical block size that is different from the block size of
the base bdev (e.g. 512B logical on 4KB base bdev).
However, this is just an internal fix/preparation and there is
currently not yet a way for users to specify a different
logical block size, e.g. through an rpc.py parameter.

If no I/O command to abort was found, send message to the thread which

to abort was found, complete the abort request with failure.
spdk_nvme_ctrlr_cmd_abort_ext() is used to try aborting command whose

Before calling spdk_nvme_ctrlr_cmd_abort_ext(), save the current

spdk_bdev_abort() supports any bdev module other than NVMe bdev
module and does not check CDW0 but checks only if the completion
status is success or failure. So add bdev_nvme_abort_done() and
converts the NVMe completion status to the bdev completion status.

IO device "bdev_nvme_poll_groups" is not unregistered in the finish
module, so we need to unregister this io device, since the "nvme_if"
is staic variable in bdev_nvme.c, it's can't be accessed in common.c
so we use "g_nvme_bdev_ctrlrs" instead.

Purpose: To set the priority of the NVMe-oF connection especially
for TCP connection.
For example, the previous example can be:
trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420
With the change, it could be:
trtype:TCP adrfam:IPv4 traddr:10.67.110.181 trsvcid:4420 priority:2
The priority is optional. We try to change
spdk_nvme_transport_id but not in spdk_nvme_ctrlr_opts since
the opts in spdk_nvme_ctrlr_opts will reflect in every nvme ctrlr,
this is short of flexibility.

- env: added "destroy" method for all locks
- env: added "execution context" interface
- cache/core "id" field made private
- signature of "ocf_io_configure" changed
- "io->volume" field made private
List of changes to OCF is available at
