75f1d6484a bdev/nvme: Aggregate multiple ctrlrs into a single bdev ctrlr
This patch enables us to aggrete multiple ctrlrs in the same NVM
subsystem into a single bdev ctrlr to create multipath.

This patch has a critical limitation that ctrlrs which are aggregated
need to have no namespace. Hence any nvme bdev is not created.
However it will be removed in the next patch.

The design is as follows.

A nvme_bdev_ctrlr is created to aggregate multiple nvme_ctrlrs in
the same NVM subsystem. The name of the nvme_ctrlr is changed to be
the name of the nvme_bdev_ctrlr.

NVMe bdev module has both the failover feature and the multipath
feature now. To choose which of failover or multipath to use, add an new
parameter multipath to the RPC bdev_nvme_attach_controller.

When we attach a new trid to the existing nvme_bdev_ctrlr, we use the failover
feature if multipath is false, we use the multipath feature if multipath is
false.

nvme_bdev_ctrlr has a list for nvme_ctrlr and it is guarded by the
global mutex. Callers can query nvme_ctrlrs from a nvme_bdev_ctrlr via
trid as a key. nvme_bdev_ctrlr is not registered as io_device.

14535253f1 bdev/nvme: Reset the nvme_ctrlr if an I/O qpair is disconnected
Previously, if an I/O qpair is disconnected, we tried reconnecting
the qpair. However, this reconnect operation was very likely to fail
and will not match the upcoming asynchronous connect/reconnect
operation. We need an extra callback to make this reconnect operation
asynchronous, but we do not want to have it.

Hence if an I/O qpair is disconnected, we free the I/O qpair and then
reset the corresponding nvme_ctrlr immediately. If the admin qpair is
also disconnected, the nvme_ctrlr is reset immediately. However this
event may never happen. So we do not wait for the error of the admin
qpair.

The NVMf host may disconnect connections by itself intentionally.
In this case, resetting the nvme_ctrlr will surely fail. But resetting
the nvme_ctrlr frees all I/O qpairs of the nvme_ctrlr and these I/O
qpairs are not created again until resetting the nvme_ctrlr succeeds.
Resetting the nvme_ctrlr once at most is more efficient than repeating
reconnecting the I/O qpair. So this change is valuable even for such
intentional disconnection. However, it is helpful to know the event that
I/O qpair is disconnected. Hence change DEBUGLOG to NOTICELOG in the
disconnected callback. The disconnected callback is not repeated, and
we do not need to worry about NOTICELOG flooding.

Refine the unit test case to verify this change.

87e9ae4035 bdev/nvme: Poll group manages ctrlr channels for qpair disconnect
Poll group has a list of the associated ctrlr channels to update
them when the corresponding I/O qpair is disconnected to do path
failover.

Another idea is that poll group has a list of the associated bdev
channels. However, two or more bdev channels may share a single
ctrlr channel and I/O qpair is per ctrlr channel. What we want to do
by this addition is to stop I/O submission to any failed I/O qpair
and choose alternative I/O qpair. Hence we take the first idea.

Previously nvme_ctrlr_channel had a pointer to a nvme_ctrlr and used it

2ee6ab36f9 bdev/nvme: bdev_nvme_reset() follow spdk_nvme_ctrlr_reset() about return value
Previously bdev_nvme_reset() returned -EBUSY if ctrlr is being
destructed and returned -EAGAIN if ctrlr is being reset.

These did not match what spdk_nvme_ctrlr_reset() returned.

Reset operation will be more important than current when multipath
is supported and reset operation is made asynchronous.

Hence change bdev_nvme_reset() to follow spdk_nvme_ctrlr_reset().
bdev_nvme_reset() returns -ENXIO if ctrlr is being destructed and
returns -EBUSY if ctrlr is being reset.

Additionally change the return value of bdev_nvme_failover()
accordingly. After the change bdev_nvme_failover() returns -ENXIO
if being destructed and returns -EBUSY if ctrlr is being reset.

b0a6496a7b bdev/nvme: Save probe_ctx in nvme_ns and populate_namespace_done() refer it
nvme_ctrlr_populate_namespace_done() needs nvme_ns, probe_ctx, and completion
status.

When multipath is supported, nvme_ctrlr_populate_namespace_done() will
be called from the spdk_for_each_channel() callback. The spdk_for_each_channel()
callback can have one context and one completion status.

Hence nvme_ns or probe_ctx need to have another.

If an nvme_ctrlr has multiple namespaces, a probe_ctx is shared by
multiple nvme_ns.

So let nvme_ns has probe_ctx.

fbbc8c4f81 bdev/nvme: Restore the removed async callbacks for populating namespaces
For multipath, when an new nvme_ns is added to an existing nvme_bdev,
we need to add the corresponding qpair to all existing nvme_bdev_channels
dynamically. The RPC bdev_nvme_attach_controller has to return after that.
Hence populating namespace needs to be asynchronous.

On the other hand, when an nvme_ns is removed from an existing nvme_bdev,
we need to remove the corresponding qpair from all existing nvme_bdev_channels
dynamically. Hence depopulating namespace needs to be asynchronous.

By the recent refactoring, two callbacks, nvme_ctrlr_populate_namespace_done()
and nvme_ctrlr_depopulate_namespace_done() were removed accidentally.
We need to restore these.

6e5d6032a0 bdev/nvme: use spdk_nvme_ctrlr_prepare_for_reset()
When preparing for a reset, use this new call to tell
the driver to avoid sending DELETE_CQ/SQ commands to a
PCIe controller when they aren't needed.

Fixes issue #2073.

efbab14933 bdev/nvme: Separate attach_cb between creating ctrlr and setting failover
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.

If ctrlr supports ANA log page, nvme_ctrlr allocates a buffer for ANA
log page and read ANA log page itself, and then each nvme_ns sets its
ANA state by parsing ANA log page.

Most code was brought from NVMe driver because NVMe driver already
supports ANA log page management. However it had a bug that assumed
each descriptor is 8-bytes aligned. Fix the bug together in this
patch. Besides, the implementation in NVMe driver was synchronous.
NVMe bdev module reads ANA log page asynchronously instead.

The next patch will support ANA log page update by AER handler.

bdev_nvme_reset() will be used by JSON RPC and we will have to call
the callback to JSON RPC at bdev_nvme_reset_complete(). To do it
easily, register the current completion function for nvme_bdev_io
in bdev_nvme_reset_complete() into nvme_ctrlr as a generic callback.

c213f1b452 bdev/nvme: Revert reset_io to bring nvme_bdev_io as context
When we support multipath, reset_io will hold the controller currently
being reset to reset all underlying controllers sequentially.

bdev_nvme_submit_request() basically passes nvme_bdev_io to each I/O
type, and we have a convenient helper function bdev_nvme_io_complete()
which has nvme_bdev_io as a parametetr.

So revert the previous change to bring nvme_bdev_io as context

nvme_bdev_first_ctrlr() and nvme_bdev_next_ctrlr() were not possible
to hold mutex correctly, and nvme_ctrlr_get() and nvme_ctrlr_get_by_name()
had not held mutex.

nvme_bdev_first_ctrlr() and nvme_bdev_next_ctrlr() were replaced by
nvme_ctrlr_for_each() in the last patch.

In this patch, add mutex to three helper functions, nvme_ctrlr_get(),
nvme_ctrlr_get_by_name(), and nvme_ctrlr_for_each().

Add mutex to nvme_ctrlr_create() but it will be removed in the

By the next patch, nvme_io_channel will be used as an I/O channel
to a single nvme_bdev. This channel is created to a single
nvme_bdev_ctrlr and has a corresponding I/O qpair. nvme_io_path

5863f95ae4 bdev/nvme: Submit abort command for admin command on the current thread
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.

64c6ddbf95 bdev/nvme: respond to attach RPC after bdev is examined
This makes use of newly added spdk_bdev_wait_for_examine(),
to only respond to RPC when bdev was fully examined.

Fixes #1760

Issue above was triggered in DD tests where application
finished before the examine had a chance to fully finish.
This patch addresses it by making sure that nvme attach
RPC waits for completion of the examine.
Later patch in series adds the bdev_wait_for_examine RPC
to multiple static configuration files. Making sure similar
issues do no occur for bdev modules which do not have changes
in their RPC as here.
The issue does not occur for JSON configs generated from apps,

3faf457f56 bdev/nvme: do not use DSM to emulate write zeroes
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.

Fixes issue #1932.

68a8502f1c bdev/nvme: Remove nvme_ns->ref and use nvme_ns->populated and nvme_ns->bdev instead
As said in the previous patches, nvme_ns->ref is 2 at most, and
first is for populating namespace and second is for nvme_bdev.
On the other hand, nvme_ns->populated is for populating namespace
and nvme_ns->bdev is for nvme_bdev.

Preparation was done by the preceding patches. Let's remove nvme_ns->ref
and use nvme_ns->populated and nvme_ns->bdev instead.

We have unit tests for both normal case and shutdown case now.
So regression will be avoided.

b1d6c2f3cb bdev/ocssd: Add ocssd_ns->depopulate_pending to complete pending depopulation
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().

8cc81fa07a bdev/nvme: Inline nvme_bdev_ns_detach()
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.

059dcf1da1 bdev/nvme: add support for zoned namespaces
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.

f84b70f6b1 bdev/nvme: Separate start and for_each_channel operations of _bdev_nvme_reset()
We need to pass bio only when the reset request came from the upper
layer. Previously, bdev_nvme_reset() called _bdev_nvme_reset() and
_bdev_nvme_reset() had the second parameter, ctx, to pass bio to
for_each_channel(). However, it was not clean.

Let's separate bdev_nvme_reset() which processes a reset request
came from the upper layer and _bdev_nvme_reset() which proesses
an internal reset request by adding a helper function
_bdev_nvme_reset_start().

The next patch will remove the second parameter, ctx, from
_bdev_nvme_reset() for clarification and further refactorings.

d22497a72c bdev/nvme: Process pending destruct ctrlr request by adding an new variable
The recent refactoring removed the destruct poller and change the
reset processing to destruct ctrlr after its completion by conditionally
sending message.

But differentiating callback function is difficult if we reset multiple
ctrlrs.

If nvme_bdev_ctrlr->destruct is set, any new reset cannot start. So we can
use an new variable and always execute the callback function.

Add an new variable pending_destruct to struct nvme_bdev_ctrlr, and set
pending_destruct if ctrlr->ref is zero and ctrlr->destruct is true, and
then start destruct ctrlr if ctrlr->destruct_after_reset is set after
clearing pending resets.

e7c019874c module/bdev/nvme: improve portability
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.

e4070ee0e0 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 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

acf116c6d5 bdev/nvme: run poller more frequently while probe in progress
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.

nvme_bdev_ctrlr pointer is already cached to nvme_io_channel.
Hence let's remove it from the helper functions, bdev_nvme_create_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.

17afd268df nvme: call correct remove_cb when device is removed
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.

Fixes issue #1715.

f85b860d27 bdev/nvme: Add failover trid to an existing ctrlr in the attach callback
Previously, we separated two cases, creating an new nvme_bdev_ctrlr
and adding an new path to an existing nvme_bdev_ctrlr as early as
possible.

However, we can merge creating an new connection between these two
cases. In this patch, connect_attach_cb() calls bdev_nvme_add_trid()
and then calls spdk_nvme_detach() if the nvme_bdev_ctrlr whose name is
ctx->base_name already exists.

This will simplify ANA multipath feature.

317dd9f740 bdev/nvme: Move add_trid() up and remove_trid() down in a file
Move bdev_nvme_add_trid() up in a file to locate it before
connect_attach_cb(). The next patch will change bdev_nvme_add_trid()
to be called by connect_attach_cb() to merge the connect operation
for failover case.

bdev_nvme_add_trid() will be associated more closely with
connect_attach_cb() and bdev_nvme_create(). To make it clear,
move bdev_nvme_remove_trid() down before bdev_nvme_delete() too.

bd65fef240 bdev/ocssd: Add ocssd_bdev parameter to I/O submit functions
nvme_bdev passes not spdk_bdev_io but nvme_bdev_io pointer to I/O
submit functions, and gets spdk_bdev_io pointer from nvme_bdev_io
pointer in its completion callback functions.

This is very clean because spdk_bdev_io is processed by the generic bdev
layer and nvme_bdev_io is processed by the NVMe bdev module.

The patch series changes ocssd_bdev to pass not spdk_bdev_io but
bdev_ocssd_io pointer to its I/O submit functions.

This patch is the first of the series and add ocssd_bdev parameter
to I/O submit functions. ocssd_bdev pointer is got from
bdev_io->bdev->ctxt. Hence this patch removes one dependency on
spdk_bdev_io.

One noticeable small change is that get_zone_info() gets zone_info
from not bdev_io->bdev but nvme_bdev->disk to advance removing
the dependency on spdk_bdev_io.

When we support ANA multipath, I/O path will get nvme_bdev_ns from

As a side effect, nvme_io_channel->ctrlr is helpful to simplify

01f769c62a bdev/nvme: Ensure ctrlr->destruct is set only once
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.

350df1c6fe bdev/ocssd: Rename the local variable nvme_ioch by nvme_ch
This change follows the standard nvme bdev.

Two local variables used ioch for nvme_io_channel and they were
confusing. Rename them by nvme_ch too.
