rdma_reg_msgs() was replaced by ibv_reg_mr() recently to support
persistent PD per RDMA device. The difference between rdma_dereg_mr()
and ibv_dereg_mr() is only return value and errno. For consistency,
replace rdma_dereg_mr() by ibv_dereg_mr().

Get a PD for the device from the PD pool managed by the RDMA provider

By this change, PD is managed completely by the RDMA provider or the hooks.

SPDK NVMe RDMA initiator used the default PD per RDMA device. Default PD
may be changed when all QPs for the RDMA device are destroyed and created
again.
For multipath, the RDMA zero copy feature require the PD per RDMA device
to be persistent when all QPs for the RDMA device are destroyed and
created again.
Maintain such persistent PDs in this patch.
Add two APIs, spdk_rdma_get_pd() and spdk_rdma_put_pd().
In each call of two APIs, synchronize RDMA device list with
rdma_get_devices().
Context may be deleted anytime by rdma-core. To avoid such deletion,
hold the returned array by rdma_get_devices().
RDMA device has PD, context, ref. count, and removed flag. If context
is missing in rdma_get_devices(), set the removed flag to true. Then,
if the ref count becomes zero, free the PD and the RDMA device.
The ref. count of a RDMA device is incremented when spdk_rdma_get_pd()
is called and decremented when spdk_rdma_put_pd() is called.
To simplify synchronization, sort the returned array by
rdma_get_devices().
To avoid resource leakage, add destructor function and free all PDs
and related data at termination.

There may be for_each operations outstanding on an
io_device when it is unregistered. Currently we just
return when this happens, not unregistering the
device but also not notifying the caller that this
happened (since it returns void, and the callback
function doesn't have a status parameter either).
We could just push this responsibility to the caller,
to never unregister an io_device if it knows it has
outstanding for_each calls waiting to complete. But
I think we can simplify this a lot by just handling
this inside of the thread library. Mark that the
device is pending registration, and unregister it
(on the original requesting thread!) when the
for_each count gets back to zero. Also don't
allow any new for_each operations either.
Note this requires a bit of refactoring on the
thread unit tests, since it is now possible to
unregister a device with outstanding for_each
operations.

When decoupling a snapshot from its parent, we need to clear its parent.
So we should remove the xattr BLOB_SNAPSHOT. Modifying the xattrs of a blob
only works if its metadata are not in read-only mode.
By default, a snapshot is in read-only mode so this operation fails. When we
later want to delete the snapshot, we will see that it has a parent, so we will
try to remove the snapshot from its parent's clones list. This will cause a
crash.
The fix is to remove the BLOB_SNAPSHOT xattr only after setting the snapshot's
metadata in rw mode.

bdev and QoS configured with read bandwidth limited to 10 MB/s and
write bandwidth limited to 100 MB/s. First we start nvme_perf with
only write IOs and we see that reported bandwidth is 100 MB/s. Then we
start another instance of nvme_perf with only read IOs. We see that
reported read bandwidth is 10 MB/s but we also see that write
bandwidth also drops to 10 MB/s.

Original implementation creates pollers and CQs for all discovered
devices at poll group creation. Device (ibv_context) that has no
references, i.e. has no QPs, may be removed from the system and
ibv_context may be closed by rdma_cm. In this case we will have a CQ
that refers to closed ibv_context and it may crash in ibv_poll_cq.
With this patch pollers are created on demand when we create the first
QP for a device. When there are no more QPs on the poller, we destroy
the poller. This also helps to avoid polling CQs that don't have any
QPs attached.

When a bdev is registered, it is examined by the bdev modules before the
bdev register even is notified.
Examination may be asychronous, e.g. when the bdev module has to perform
I/O on the new bdev.
This causes a race condition where the bdev might be destroyed while
examination is not finished. Then, once all modules have signaled that
examination is done, `bdev_register_finished` makes an invalid access to
the freed bdev pointer.
To fix this, defer the unregistration until the examine is completed by
opening a descriptor on the bdev.

That is possible to get/set registers from any thread,
during regs processing we are polling admin qpair to
get a completion. At the same time, another thread
can also poll admin qpair and that can lead to
undefined behavior.
This patch fixes an issue when bdev_nvme is configured
with io_timeout. If remote target becomes unresponsive
(e.g. due to link down), IO timeout occurs and bdev_nvme
tries to get csts registers in timeout_cb. At the same
time another thread can process adminq, so we may have
2 simultaneous adminq polls. If admin qpair is disconnecting
at that time (RDMA transport) we may destroy resources
twice from different threads.
We don't see a problem with set_regs function but it
won't be redundant to lock mutex in set_regs as well.

We cannot count AERs as outstanding IO for purposes

in nvmf_ctrlr_async_event_request() by decrementing
the counter, but this did not consider cases in the
calling function (nvmf_ctrlr_process_admin_cmd) where
an AER might complete with error before this function,
resulting in the counter getting stuck indefinitely
with a >0 value.
Rather than adding a decrement in all of those
error cases, do a single check at the beginning
of nvmf_ctrlr_process_admin_cmd, and remove the
one from nvmf_ctrlr_async_event_request.

In corner test, there might be 4 bytes data packet sent to
NVMe/TCP target, after that, if there is no more data sent to
the same socket, the 4 bytes won't be read by NVMe/TCP target
qpair thread. Because of this, there is a IO request didn't

It is a nicer API to allow users to use an
md-related API such as spdk_bdev_read_blocks_with_md
passing md_buf as NULL to mean "don't read metadata".
This avoids the need for an if-statement in the users
code to check if the md buffer is NULL before deciding
which API needs to be called.
This basically requires two changes:
1) only check if the metadata is separate for the bdev
if the md_buf != NULL
2) do not fail if the buffer is specified but the
md buffer is not (we only need to fail the case where
the md buffer is specified but the data buffer is not)
Note that spdk_bdev_readv/writev_blocks_ext was already
allowing the metadata buffer to be NULL, but change
those functions too to match the others on how we check
if the data buffer isn't allocated.

Currently we initialize pending_bytes only in pre-copy state. This is
pointless since we don't generate any migration data at this state, so
if the vfio-user client reads migration data it will be garbage. Even
worse, we don't re-initialize pending_bytes in stop-and-copy state, so
if the vfio-user client reads the entire migration data in pre-copy state
then there will be nothing left to read in the stop-and-copy state,
which is where we actually produce the migration data. This results in
corruption of the controller's state (e.g. queues).
This patch ensures that migration data are available in the

nvme_tcp_req_complete_safe caches values on
the request, so that we can free the request *before*
completing it. This allows the recently completed
req to get reused in full queue depth workloads, if
the callback function submits a new I/O.
So do this nvme_tcp_req_complete as well, to make
all of the completion paths identical. The paths
that were calling nvme_tcp_req_complete previously
are all non-fast-path, so the extra overhead is
not important.
This allows us to call nvme_tcp_req_complete from
nvme_tcp_req_complete_safe to reduce code duplication,
so do that in this patch as well.

All callers of nvme_tcp_req_complete call
nvme_tcp_req_put immediately afterwards, so move
this call into nvme_tcp_req_complete.
This will help enable some improvements in later
patches.
Note that nvme_tcp_req_complete_safe has this same
functionality open coded right now, but that will
get changed in the next patch. It calls
nvme_tcp_req_put immediately after the TAILQ_REMOVE,

The issue here is that in the bdev_set_qd_sampling_period RPC
command, the QD sampling period has been set. Then later the
related Desc is closed and in the bdev_close() function the
QD sampling period is reset to 0.
A new QD desc is added as the QD sampling period update could

Meanwhile, a new QD Poll In Progress flag is also added so as
to indicate there are ongoing events of QD sampling and the
Bdev unregister will be handled in the proper way.
Related test case and unit test also updated for this change.

1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names
Deal with 1) by adjusting the check_format.sh script to only tell astyle

On the submitter's system, this resulted in an error:

I have no idea why no one has ever run into this
error, except for this one submitter. But removing

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

This patch adds virtio_blk abstraction for custom transports,
with the 'vhost_user_blk' first one being used.
Added spdk_virtio_blk_transport_ops describing the nessecary
callbacks to be implemented by each transport.
Please use SPDK_VIRTIO_BLK_TRANSPORT_REGISTER to register the transport.
Transports can use virtio_blk_process_request() to process the
incoming I/O from their queues.
virtio_blk_create_transport RPC was added to create one of the
registered transports, possibly with custom JSON arguments.
Added 'transport' argument to vhost_create_blk_controller RPC,
to specify which transport should create the controller.
By default the vhost_user_blk transport is used.

Generic vhost-blk layer is responsible for opening the bdev
attached to the vhost controller.
This patch adds vhost_user_bdev_event_cb() that is called
for vhost_user backend. This function will be replaced with
a callback to particular virtio-blk transport.
Having this piped through to the transports, allows
to adjust their behavior upon bdev events.

the virtio device based on spdk_bdev properties.
Please see vhost_blk_get_config() for an example
of vhost_user retrieving properties of bdev such as size

Rather than trying to anticipate every such property,
add vhost_blk_get_bdev() to allow usage of bdev API directly.

ext_io_opts uses the size member to allow backwards
compatibility however currently we only check if it is
below or equal the current size of the opts struct and
that it is not 0. size is only used when we copy opts
because of split or push/pull.
This patch introduces size checks to allow safe access
to e.g. metadata and memory domain pointers of the user
provided opts pointer. The minimum size of the struct
passed is now the size of the initial version of
spdk_bdev_ext_io_opts. To not introduce additional
checks when opts are consumed by a bdev module we
now always copy if the size is smaller than the
current opts struct size.
When introducing new members to opts additional
checks might be needed if those are directly accessed
through the passed pointer or bdev_io->internal.ext_opts.

Previously, we did not do any Controller Level Reset when disconnecting
the admin qpair.
However, for PCIe transport, we need to stop any activity of the
controller, i.e., delete all I/O SQ and CQs before
nvme_transport_ctrlr_disconnect_qpair_done() calls
nvme_transport_qpair_abort_reqs() (i.e., nvme_pcie_qpair_abort_trackers()).
Otherwise, some corruption may occur because completed I/Os may still be
in progress on the NVMe device.
Not to change any public API, nvme_pcie_ctrlr_disconnect_qpair() is a
convenient place to initiate a Controller Level Reset because it is
called from spdk_nvme_ctrlr_disconnect(). Then
nvme_pcie_qpair_process_completions() can process it until completion.
However, necessary functions are not accessible from PCIe transport.
This patch adds two helper functions and guards us from some undesirable
behaviors because it was not assumed that nvme_ctrlr_process_init() is
called from the completion context and ends in the middle of transition.

With this change blob_write_extent_page() expects

so memory allocated for qpair is freed but rdma

receive rdmacm event (DISCONNECTED) for the destroyed qpair,
that leads to use-after-free.
To fix this problem, add a check for internal qpair state

In the following patches, nvme_ctrlr_process_init() will be used to
disable the controller when disconnecting the admin qpair for PCIe
transport. In this case, we will have to exit nvme_ctrlr_process_init()
after CSTS.RDY is 0. However, spdk_nvme_ctrlr_reset() and
spdk_nvme_ctrlr_reconnect_poll_async() have to continue
nvme_ctrlr_process_init() until the controller becomes ready.
To differentiate stop and continue clearly, add a new state
NVME_CTRLR_STATE_DISABLED to enum nvme_ctrlr_state.

When using the SPDK nvme driver in multi-process mode,

(i.e. at application exit) very close to each other,
there are cases where a process can have started its

So we need to remove the assertion in pci_device_fini(),

The bdevio test app has some test cases verifying
that write zeroes commands are handled correctly,
but using knowledge of the ZERO_BUFFER_SIZE that
the bdev library uses for splitting larger write
zeroes commands. Instead of hardcoding that 1MB
value in bdevio.c, have bdevio.c use ZERO_BUFFER_SIZE
directly instead. But this requires moving
ZERO_BUFFER_SIZE into bdev_internal.h and having
bdevio.c include that file.
We do this instead of putting ZERO_BUFFER_SIZE in
the public API because we don't want users to
make any kind of dependencies on this value.
While here, also rename the tests that are using this
value, so that the test names don't include any reference
to the specific size of this bdev-internal zero buffer
size.

In the qemu virtualization environment, when the virtio driver of the
windows image is upgraded to virtio-win 0.1.185, and virtio uses
legacy mode. In the negotiation stage of vhost, qemu's host_features
will enable VIRTIO_F_ANY_LAYOUT, and guest_features will also enable
this feature, because qemu's feature is a superset, so the feature
will be passed to the spdk side through the set feature process,
which leads to "VHOST_CONFIG: Processing VHOST_USER_SET_FEATURES
failed. VHOST_CONFIG: vhost message handling failed.", so we enable
this bit for spdk vhost.

There is a race condition when a bdev is unregistered while reset is
submitted from the upper layer very frequently.
spdk_io_device_unregister() may fail because it is called while
spdk_for_each_channel() is processed.
spdk_io_device_unregister io_device bdev_Nvme0n1 (0x7f4be8053aa1)
has 1 for_each calls outstanding
To avoid this failure, defer calling spdk_io_device_unregister() until
reset completes if reset is in progress when unregistration is ready
to do, and then reset completion calls spdk_io_device_unregister()
later.
A bdev cannot be opened if it is already deleting. So we do not need
to hold mutex.

Transport specific qpair_abort_reqs() set SC to SC_ABORTED_SQ_DELETION.
However, nvme_qpair_abort_queued_reqs() set SC to SC_ABORTED_BY_REQUEST
even if its call is not requested by the upper layer.
Change nvme_qpair_abort_queued_reqs() to set SC to SC_ABORTED_SQ_DELETION
for consistency.
nvme_qpair_abort_queued_reqs() is used to abort queued requests that
were sent while adminq was connecting. SC_ABORTED_SQ_DELETION will not
be so bad even for the case.
This change is required for the NVMe bdev module to be resilient for I/O
error. The NVMe bdev module does not retry I/O if SC is
SC_ABORTED_BY_REQUEST.
SC is set to SC_INTERNAL_DEVICE_ERROR if a request is failed to submit
to qpair by a generic qpair layer. We can change it to
SC_ABORTED_SQ_DELETION as well but we keep this for now.
SC_INTERNAL_DEVICE_ERROR is also retriable for the NVMe bdev module.

As per the NVMe specification, a host can identify two areas of guest
memory: one of which is used for the host-written doorbells, and one of
which contains event indexes. The host writes to the shadow doorbell
area, but also writes to the controller's BAR0 doorbell area if the
corresponding event index is crossed by the update. This avoids many
mmio exits in interrupt mode, where BAR0 doorbells are not directly
mapped into the guest VM, with greatly improved performance.
This isn't a useful feature in BAR0 doorbells are mapped into the VM, so
we explicitly disable support in that case.
NB: the Windows NVMe driver doesn't yet support this feature.
Although the specification says that the admin queues should also engage
in this behaviour, in practice, no VM does, so have to include some
hacks to account for this.

Now that IO qpairs can be created asynchronously, we need to make sure
that all the create IO CQ/SQ commands can be executed simultaneously.
It is pretty common to create multiple IO qpairs at the same time, e.g.
adding an NVMe bdev to an nvmf subsystem will create an IO qpair on each
poll group. In that case, if the number of cores exceed the size of the
admin queue (actually it can be even lower due to outstanding AERs), we
might run out nvme_requests on the admin queue.
The chosen minimum value for the admin queue size, 256, should be enough
to cover most cases.

Removing it simplifies any code in SPDK that uses

the capabilites enum which held bit positions for each opcode
has been removed. Only the opcodes enum remains and thus only
opcodes are used throughout. For the capabiltiies bitmap a helper

now it is used in the IO path but in upcoming patches that goes away

spdk_for_each_bdev() can be applied simply to rpc_bdev_get_bdevs()
because the callback function rpc_dump_bdev_info() is synchronous.
spdk_for_each_bdev() cannot be applied simply to rpc_bdev_get_iostat().
The factored-out callback function _bdev_get_device_stat() is
asynchronous. Add desc pointer to struct spdk_bdev_io_stat and open
before and close after executing spdk_bdev_get_device_stat().
Replace spdk_bdev_get_by_name() by spdk_bdev_open_ext() when a bdev name
is specified.
spdk_bdev_register() checks if the name of each bdev is set and each bdev
is opened while collecting its stats now. Hence it is not possible that
spdk_bdev_get_name() returns NULL. Simplify rpc_bdev_get_iostat_cb()
based on this fact.
Furthermore, we want to fail the RPC for all failures. The callback
function to spdk_bdev_get_device_stat() is executed after stack
unwinding if successful. Defer starting RPC response until it is ensured
that all spdk_bdev_get_device_stat() calls will succeed or there is no bdev.

RDMA READs can cause cmds to be submitted to the target
layer in a different order than they were received
from the host. Normally this is fine, but not for
fused commands.
So track fused commands as they reach
nvmf_rdma_request_process(). If we find a pair of
sequential commands that don't have valid FUSED settings
(i.e. NONE/SECOND, FIRST/NONE, FIRST/FIRST), we mark
the requests as "fused_failed" and will later fail them
just before they would be normally sent to the target
layer.
When we do find a pair of valid fused commands (FIRST
followed by SECOND), we will wait until both are
READY_TO_EXECUTE, and then submit them to the target
layer consecutively.
This fixes issue #2428 for RDMA transport.

Replace nvme_fabric_qpair_connect() by nvme_fabric_qpair_connect_async()
and nvme_fabric_qpair_connect_poll().
The following is a detail.
Define state of the nvme_rdma_qpair and each rqpair holds it.
Initialize rqpair->state by INVALID at nvme_rdma_ctrlr_create_qpair().
_nvme_rdma_ctrlr_connect_qpair() sets rqpair->state to
FABRIC_CONNECT_SEND instead of calling nvme_fabric_qpair_connect().
Then the new function nvme_rdma_ctrlr_connect_qpair_poll() calls
nvme_fabric_qpair_connect_async() at FABRIC_CONNECT_SEND and
nvme_fabric_qpair_connect_poll() until it returns 0 at FABRIC_CONNECT_POLL.
nvme_rdma_qpair_process_completions() or
nvme_rdma_poll_group_process_completions() calls
nvme_rdma_ctrlr_connect_qpair_poll() if qpair->state is CONECTING.
This patter follows the TCP transport.

spdk_sock_map_insert() allows for allocating a sock_map

Placement_id's are allocated first, then an empty one is found
using spdk_sock_map_find_free().
Since the above is a valid use case, then entry in sock_map
can exist without a group assigned. spdk_sock_map_lookup() has

R2Ts can cause cmds to be submitted to the target
layer in a different order than they were received
from the host. Normally this is fine, but not for
fused commands.
So track fused commands as they reach
nvmf_tcp_req_process(). If we find a pair of sequential
commands that don't have valid FUSED settings (i.e.
NONE/SECOND, FIRST/NONE, FIRST/FIRST), we mark the
requests as "fused_failed" and will later fail them
just before they would be normally sent to the target
layer.
When we do find a pair of valid fused commands (FIRST
followed by SECOND), we will wait until both are
READY_TO_EXECUTE, and then submit them to the target
layer consecutively.
This fixes issue #2428 for TCP transport.

Some targets report they support log page offset,

a non-zero offset, or report the wrong number
of discovery entries when reading more than the
discovery log page header but not the entire log
page.
So just revert to reading the entire discovery log
page, after we've read the header to know how big the
log page will be. This means that when we read the
log page initially (without the individual entries),
we need to save off the genctr, since it will get
overwritten when we read the log page again. We can
just store this in the discovery context, and compare
it to the genctr that we read with the whole log page.

If we're in interrupt mode and live migrating a guest, there is a window
where the I/O queues haven't been set up but the device is in running
state, during which the guest might write to a doorbell. This doorbell
write will go unnoticed. This patch ensures that we re-check the
doorbells after an I/O queue has been set up.

Parameters submitted by bdev trace record may not be uint64_t
type (ex: bdev_io->type), which may bring outliers in trace parsing
results. The reason is that, in _spdk_trace_record() function,
va_list hold information about variable arguments, when passing
SPDK_TRACE_ARG_TYPE_INT arguments, it will call va_arg(vl, uint64_t)
to get value. However, if the submitted type is not uint64_t,
va_arg may return outlier.
To solve the problem, the parameter should be converted into
uint64_t before be delivered into trace record if it is not
uint64_t.

Ideally the vhost_user_dev_unregister() should be the only

This should not pose any issue, as vhost_scsi is still dependent

If async qpair disconnect is supported, even when connect qpair failed,
nvme_transport_ctrlr_connect_qpair() may complete asynchronously later.
The cases that qpair->async is set to true are I/O qpair for the NVMe
bdev module and admin qpair.
example/nvme/perf and example/nvme/reconnect use I/O qpair but both
set qpair->async to false.
For the NVMe bdev module, I/O qpair is connected when creating I/O
channel or resetting ctrlr. If spdk_nvme_ctrlr_connect_io_qpair()
returns 0 for a I/O qpair, the qpair is in a poll group and is polled
by spdk_nvme_poll_group_process_completions() and a disconnected
callback is called to the qpair. Hence we do not need to add additional
polling for I/O qpair in the NVMe bdev module.

spdk_nvme_poll_group has followed spdk_nvme_qpair about how to
process I/O qpair deletion inside of a completion context.
spdk_nvme_qpair_process_completions() accesses qpair after
returning from nvme_transport_qpair_process_completions().
So this is reasonable.
On the other hand, if spdk_nvme_poll_group_process_completions()
can execute spdk_nvme_ctrlr_free_io_qpair() inside of a completion
context, the target qpair is ensured to be deleted after returning
from spdk_nvme_ctrlr_free_io_qpair(). Then the target qpair is
not accessed anymore in spdk_nvme_poll_group_process_completions().
Remove two variables, in_completion_context and num_qpairs_to_delete,
of spdk_nvme_transport_poll_group and the related code.
This change is really necessary to support the following case.
In the NVMe bdev module, a nvme_qpair has a qpair and a poll_group
channel. disconnected_qpair_cb calls spdk_nvme_ctrlr_free_io_qpair()
for the qpair and spdk_put_io_channel() to the poll_group_channel.
spdk_nvme_ctrlr_free_io_qpair() is executed after unwinding stack
but spdk_put_io_channel() is executed now. The callback to
spdk_put_io_channel() calls spdk_nvme_poll_group_destroy(). However,
spdk_nvme_ctrlr_free_io_qpair() is not executed. Hence
spdk_nvme_poll_group_destroy() fails.

When generating a discovery log page, we will add entries
for the discovery subsystem for all listeners except the
one associated with the controller that generated the
log page command. We do this comparison using
spdk_nvme_transport_id_compare().
But this function compares the subnqn of the trid, and
the subnqn is not set in either of the trids that we
are comparing.
The listener's trid always has an empty subnqn, but
the source trid has an uninitialized subnqn when
we do the comparison. This means that sometimes the
subnqn may be empty (which always happens in debug
builds) but sometimes may contain garbage. This
means that sometimes an entry would be added to the
log, even for the trid of the discovery controller
that generated the command (meaning the discovery
controller would end up referring to itself which
is not allowed).
There is an even more subtle issue with this. If the
host reads just the log page header, the nvmf target
generates the entire log page, and just returns the
header contents. Let's say in this case, the source
trid has an empty subnqn, so we don't generate an entry
for it, and report numrec = X and genctr = Y. Then
the host reads the X log page entries. But now the
source trid is garbage, so a discovery log page entry
is returned, replacing one of the "real" log page
entries. And since genctr didn't change, the host

spdk_sock_close() may not complete synchronously.
Then the following scenario is possible.
ctrlr_disconnected_qpair() calls spdk_sock_close(). Then any request may
complete and call _pdu_write_done(). qpair is still associated with a
poll_group and is inserted into the group->needs_poll list.
After ctrlr_disconnected_qpair() completes, disconnected_qpair_cb() is
called. disconnected_qpair_cb() calls spdk_nvme_ctrlr_free_io_qpair().
spdk_nvme_ctrlr_free_io_qpair() calls spdk_nvme_poll_group_remove().
spdk_nvme_poll_group() removes qpair only from the
group->disconnected_qpairs list.
Even after qpair->poll_group is nullified, qpair is still in the
group->needs_poll list.
Then spdk_nvme_poll_group_process_completions() polls all qpairs in
the group->needs_poll list and hits the assert.

The root ports might have been configured by some other driver (e.g.
Linux kernel) prior to loading the SPDK one, so we need to clear it. We
need to before the scanning process, as it's depth-first, so when
scanning the initial root ports, the latter ones might still be using
stale configuration. This can lead to two bridges having the same
secondary/subordinate bus configuration, meaning that their config space
would map to the same memory area, which, of course, isn't correct.
This has manifested in issue #2413, where two root ports were configured
to use the same secondary bus. This caused an endpoint device to be
enumerated twice on two different root ports, with the first instance
being broken once the second port was configured by the SPDK driver.

To fully support interrupt mode for the vfio-user transport, we need to
arrange to wake up in one of two conditions:
- we receive a vfio-user message on the socket
- a client writes to one of our BARs
In response, we can process any pending vfio-user messages, as well as
poll the actual queue pairs.
As there is no way for a client-mapped BAR write to cause us to wake up,
interrupt mode can only work when mappable BAR0 is disabled. In that
case, each BAR write becomes a vfio-user message, and can thus be
handled by registering the libvfio-user socket fd with SPDK.
For the poll group poller, we enable interrupt mode for it during the
vfio-user ->poll_group_create() callback; this only works in the case
that no other transports without interrupt mode support are sharing that
poll group.

Currently we accept connections to the discovery
subsystem on any listener that has been added to
any subsystem (not just the discovery subsystem).
This is not proper behavior, especially for TCP. TCP
defines port 8009 (not 4420) as the discovery port,
so the current behavior means that if NVM subsystems
are listening on port 4420, then the discovery
subsystem by default is listening there too.
For now, continue to allow connections, but print
a warning message when someone connects to the
discovery subsystem on a listener trid that wasn't
previously added.

This patch adjusts max_sges to capsule size if required. Adjustment to

hugepages that was not freed during process shutdown.
Make sure we don't enable both huge-unlink and
single-file-segments at the same time though, DPDK doesn't
support that.
Note that even when using multi-process, if hugepages
aren't released, they aren't really leaked. DPDK will

This was a parameter on the nvmf_create_transport

reduce confusion on whether this number included the
admin queue or not.
nvmf_vhost test was using this deprecated parameter.
Change it to use -m (max_io_qpairs_per_ctrlr)
instead. '-p 4' would have been evaluated as 1 admin
queue + 3 I/O queues, but it's likely the intent
was for 4 I/O queues. This is a perfect example of

Although there are no use cases right now where a batch can have
mixed op types, there may be in the future and rather than have
one blow up because ops have different reserved fields and its
not valid to submit an op with a non-zero reserved field, go
ahead and zero these out like we do with descriptors in the non
batch case.

SPDK can submit more commands to remote NVMf target than allowed by
negotiated queue size. SPDK submits up to SQSIZE commands, but only
SQSIZE-1 are allowed.
Here is a relevant quote from NVMe over Fabrics rev.1.1a ch.2.4.1
“Submission Queue Flow Control Negotiation”:
If SQ flow control is disabled, then the host should limit the number
of outstanding commands for a queue pair to be less than the size of
the Submission Queue. If the controller detects that the number of
outstanding commands for a queue pair is greater than or equal to the
size of the Submission Queue, then the controller shall:
a) stop processing commands and set the Controller Fatal
Status (CSTS.CFS) bit to ‘1’ (refer to section 10.5 in the NVMe Base
specification); and
b) terminate the NVMe Transport connection and end the association
between the host and the controller.

According to NVMe over Fabrics specification (rev.1.1a) HSQSIZE sent
in RDMA_CM_REQUEST private data (ch.7.3.6.4) shall be the same as
SQSIZE later sent in Connect command (ch.3.3).
SPDK NVMe RDMA initiator adjusts SQSIZE to CRQSIZE received from
target in RDMA_CM_ACCEPT private data. Target is allowed to send
CRQSIZE < HSQSIZE if RNR retries are used. So, it is possible that
SQSIZE sent by SPDK will be lower than previously sent HSQSIZE. There
are targets validating this match and they reject connection from
SPDK.
Linux kernel NVMe initiator doesn't perform such adjustments and
connects well to such targets.
This patch aligns SPDK behavior with specification and Linux kernel
implementation.

In many cases, addressing bdevs by their UUIDs is often easier than
using their names, which can be somewhat arbitrary. For instance, the
NVMe bdev builds a name by addng the n{NSID} suffix to the controller's
name, while the UUID is filled with NGUID (if available).
The UUID alias is stored in the form defined by RFC 4122, meaning five
groups of lower-case hexadecimal characters. It's important to note
that bdev layer uses case-sensitive name comparison, so the user needs
to use the same textual UUID representation.

In some scenarios, a split IO can immediately complete. For
example, a very large unmap operation to a newly thin-provisioned
blob has no operations to perform, so the batch for its operation
immediately completes.
But if it immediately completes, we can't recursively submit
the next split IO. So use variables in the context structure
to detect when an operation immediately completes, to allow
it to unwind and submit the next operation without recursing.
Fixes issue #2347.

If we find a blob during the initial iteration during load
that doesn't have a name, we cannot just immediately
unload the blobstore, since the 'bad' blob is still
open. Instead finish the iteration, and unload the
blobstore (with failure status) after the iteration
is complete.
This is somewhat related to issue #1831. By ensuring
we can unload the blobstore, it closes the open
descriptor on the underlying bdev, which allows
the bdev subsystem to exit on application shutdown.

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

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

The format of the region 9 migration region is as follows:

|vfio_device_migration_info| data section |
------------------------------------------------------------------
QEMU will access vfio_device_migration_info to controll the migration
process.
For SPDK vfio-user target, we also implement the BAR9 via libvfio-user,
and we also define the NVMe device specific migration data stored in
data section of BAR9. QEMU doesn't care about the format in data section,
it will help us to gather the NVMe specific migration data in source VM and
then restore the migration date to data section of BAR9 in destination VM.
The core idea to implement live migration will following the device state
change which is controlled by QEMU. First QEMU will try to STOP the device
in the source VM, and set the destination VM to RESUME state, SPDK will save
NVMe devic state data structure to BAR9 in the source VM once the subsystem
is paused, then QEMU will read BAR9 in source VM and restore the content of
BAR9 in destination VM, finally in the destination VM, we will restore the
NVMe device state include BARs/PCI CFG/queue pairs in the destination VM.

This reverts commit eb09178a59.
Reason for revert:
This caused a degradation for adminq.
For adminq, ctrlr_delete_io_qpair() is not called until ctrlr is destructed.
So necessary delete operations are not done for adminq.
Reverting the patch is practical for now.

Another problem is that some qpair's live time may exceed controller's
life time. To avoid it, start controller destruction process when the last
qpair finished the disconnect process (previously controller started
the descruction process before the last qpair starts to disconnect
and it could lead to raise conditions)

This patch is first in series that reworks vhost library
with two goals in mind:
1) Refactor vhost and vhost-blk to no longer depend on rte_vhost.
All references to that API will be moved to rte_vhost_user.c.
2) Add a transport abstraction for virtio-blk devices.
vhost-blk will now be able to expose virtio-blk using multiple
implementations of the interface.
First one will be vhost_user that depends on DPDK rte_vhost library.

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.

Previously we mixed SQ/CQ definition together, one queue pair
data structure may contain CQ,SQ or both CQ and SQ separately,
while here, we split the queue pair definition into SQ and CQ
respectively as code cleanup.
The NVMf library uses queue pair concept, but for vfio-user
case, each SQ created by VM is mapped to NVMf queue pair, so
we also change `connected_qps` to `connected_sqs` to reflect
the fact.
No actual code logic change in this commit.

nvme_ctrlr_disconnect_qpair() calls nvme_poll_group_disconnect_qpair() if the qpair
uses a poll group, and nvme_poll_group_disconnect_qpair() calls
nvme_ctrlr_disconnect_qpair() if the state of the qpair is not DISCONNECTING.
This relationship made the code very complex.
A few patches starting from this patch simplifies disconnect and free qpair
operations.
This patch swaps the ordering of nvme_ctrlr_disconnect_qpair() and
spdk_nvme_poll_group_remove() in spdk_nvme_ctrlr_free_io_qpair().
This ensures the qpair is disconnected when spdk_nvme_ctrlr_free_io_qpair()
calls spdk_nvme_poll_group_remove().
This enables us to limit spdk_nvme_poll_group_remove() to be available
only for disconnected qpairs.

This patch adds support for using zero-copy operations to execute IO
requests in the TCP transport. Of course, they're only used if the
underlying bdev supports them. Additionally, only requests with no
in-capsule-data can be executed using this mechanism.
Added several new states to accommodate for the difference in a way
zero-copy is handled. Also, these flows very depending on the type of a
request (read or write). It stems from zero-copy semantics: to perform
a write we need to wait for zcopy_end completion, while for reads
zcopy_end can only be submitted once we send all of the requested data
to the host.

Zero-copy requests are kept on the outstanding queue for the whole
duration of the request - from the initial zcopy_start submission to the
completion of zcopy_end. This means, that there's a period in which a
request doesn't wait for a completion from the bdev layer, but is still
on the oustanding queue (after zcopy_start callback, before zcopy_end
submit). If a qpair gets disconnected while a request is in this state,
we need to manually force its completion, as otherwise it might hang
indefinitely (e.g. waiting for host data).

The zero-copy requests can also be queued when a subsystem is paused, so
we need to properly resume and submit them by using zcopy_start.
Since only requests that haven't received the zero-copy buffer (i.e.
before zcopy_start was called) can be queued, we don't need to bother
with checking zcopy_phase.

We have very frequent failures when we run test/nvmf/host/multipath.sh

Call stack showed nvmf_stop_listen_disconnect_qpairs() accessed
qpair->ctrlr even if qpair->ctrlr was NULL.
nvmf_stop_listen_disconnect_qpairs() did not check if qpair->ctrlr is
not NULL before accessing qpair->ctrlr->subsys.
When a qpair is added to a poll group, qpair->ctrlr is cleared to NULL.
The test code test/nvmf/host/multipath.sh executes multiple
reconnects for path error.
So a conflict might occur between adding a qpair to a poll group and
disconnecting a qpair in a poll group.
In this case, it may be acceptable even if we disconnect a qpair whose
qpair->ctrlr is NULL. It will be better than SIGSEGV.

In current implementation RDMA qpair is destroyed right after
disconnect. That is not graceful qpair shutdown process since
there can be requests submitted to HW and we may receive
completions for already destroyed/freed qpair.
To avoid this, only disconnect qpair in ctrlr_disconnect_qpair
transport callback, all other resources will be released in
ctrlr_delete_io_qpair cb.
This patch is useful when nvme poll groups are used since in
that case we use shared CQ, if the disconnected qpair has WRs
submitted to HW then qpair's destruction will be deferred to
poll group.
When nvme poll groups are not used, this patch doesn't change
anything, in that case destruction flow is still ungraceful.
However since CQ is destroyed immediately after qpair,
we shouldn't receive any requests which point to released
resources. A correct solution for non-poll group case
requires async diconnect API which may lead to significant
rework.
There is a bug when Soft Roce is used - we may receive
a completion with "normal" status when qpair is already
disconnected and all nvme requests are aborted. Added
a workaround for it.

This patch aims to introduce a change in enabling

be stored inside an internal buffer, what is inconvenient when
looking for certain information (eg. starting IO to record
some tracepoints, stopping the IO and having the tracepoint
buffer flooded with irrelevant information before copying the
contents connected with IO operations).
The tpoint mask option (-e) has been extended with ':' character.
User may now enter tpoint mask for individual trace points
inside chosen tpoint group.
Example: "-e 0x20:3f", where "0x20" stands for tpoint group,
':' is a separator and "3f" is the tpoint mask.

Related UT has been added and updated.
1) In the default allocation (num_clusters == 0), the extent_pages is not allocated as expected.
2) In the thin provisioning allocation (num_clusters != 0), the extent_pages will be allocated if extent_table is used.
More related information as below:
The crux of the problem is that according to POSIX:
realloc: "If ptr is NULL, then the call is equivalent to malloc(size)"
malloc: "If size is 0, then malloc returns either NULL or a unique pointer value that can later be successfully passed to free"
blobstore was relying on realloc(NULL, 0) always return a unique pointer value, and not NULL. This is not portable behavior.

spdk_ioviter_next will walk through two iovecs and yield pointers
to common length segments. For example, given a source iovec (siov) with
4 1KiB elements and a destination iovec (diov) with 1 4KiB element, the
following will happen:
first spdk_ioviter_next:
src = siov[0].iov_base
dst = diov[0].iov_base
len = 1KiB
second spdk_ioviter_next:
src = siov[1].iov_base
dst = diov[0].iov_base + 1KiB
len = 1KiB
third spdk_ioviter_next:
src = siov[2].iov_base
dst = diov[0].iov_base + 2KiB
len = 1KiB
fourth spdk_ioviter_next:
src = siov[3].iov_base
dst = diov[0].iov_base + 3KiB
len = 1KiB
fifth spdk_ioviter_next:
len = 0
This is a useful utility for performing operations where both the source
and destination are scattered memory. As an example and a test vehicle,
spdk_iovcpy has been updated to use this internally.

The host may have specified a hostnqn to use to connect to

The discovery log isn't updated when a subsystem is created
or deleted, it's only updated when a listener for a
subsystem is added or removed.
So remove the nvmf_update_discovery_log() in the subsystem
create and delete paths. They just generate extra AER
completions that potentially cause the host to do unneeded
work.
Note that if a subsystem is deleted with active listeners,
the subsystem delete path will remove each of the listeners
before deleting the subsystem itself. So the discovery log
will still get updated when those listeners are removed.

the queue pair is in connecting state at the beginning, then users may call
`spdk_nvme_ctrlr_free_io_qpair` immediately, and the common layer will
change queue state to NVME_QPAIR_DISCONNECTING and NVME_QPAIR_DESTROYING,
so in function `nvme_pcie_ctrlr_delete_io_qpair` the workaround to wait
for create cq/sq callbacks will not be called, instead of using the common

The NVMe bdev module will support two features, delayed reconnect and
delete after multiple failures of reconnect to improve error recovery.
The recently added two APIs, spdk_nvme_ctrlr_reset_async() and
spdk_nvme_ctrlr_reset_poll_async(), were not good enough.
spdk_nvme_ctrlr_reset_ctx was not necessary. It had only a pointer to ctrlr.
Using a pointer to ctrlr directly saves us from undesirable malloc error
processing.
Separate spdk_nvme_ctrlr_reset_async() into spdk_nvme_ctrlr_disconnect()
and spdk_nvme_ctrlr_reconnect_async(). spdk_nvme_ctrlr_disconnect()
disconnects ctrlr including disconnecting adminq.
spdk_nvme_ctrlr_reconnect_async() moves the ctrlr state to INIT.
Then rename spdk_nvme_ctrlr_reset_poll_async() by
spdk_nvme_ctrlr_reconnect_poll_async().
Finally deprecate spdk_nvme_ctrlr_reset_async() and
spdk_nvme_ctrlr_reset_poll_async().
The following patches will change the NVMe bdev module to use these new APIs.

Since the maximum number of queues is a large value(512), so we
still define a default value when starting, users still can
overwrite this value with a number no greater than 512.

This reverts commit d9561c444f.
This patch is incorrectly iterating the CPU mask assuming it is
contiguous. However, rather than fix it, let's just let the kernel
scheduler place the thread where it thinks is best. It's going to prefer
idle cores anyway. So reverting is the simplest way forward.

Discovery services using the SPDK nvme driver may
use long-lasting connections that detect AER completions
to determine when there are changes in the discovery
log. This means that we still need to send keep alives
on discovery controller admin queues. So move the
SET_KEEP_ALIVE_TIMEOUT state immediately after
IDENTIFY, and run the SET_KEEP_ALIVE_TIMEOUT state
even for discovery controllers.
Note, we need the IDENTIFY's KAS value to properly
set the keep alive timeout, so we have to keep the
IDENTIFY state before SET_KEEP_ALIVE_TIMEOUT.

When no optimal poll group exists for a qpair,
assignment for round robin happens in spdk_nvmf_tgt_new_qpair().
RDMA transport implments the logic for this assignment in
nvmf_rdma_get_optimal_poll_group().
TCP relied on the spdk_nvmf_tgt_new_qpair() instead.
This resulted in race condition when looking up and assigning
optimal poll groups - see #2113.

There is a bad memory corruption where the code for CUSE attempts to write
one byte (with value 0x1) after the memory is freed.
Context:
When the CUSE device is unregistered, the poller thread is signaled with
fuse_session_exit(), which writes the value 1 to fuse_session::exited.
The poller thread then detects with fuse_session_exited() that it must exit
the routing and finally destroys its own fuse session with
cuse_lowlevel_teardown() before it exits.
However, FUSE may also call fuse_session_exit() for its internal purposes.
I'm not sure exactly under what conditions that happens, but I added
some trace messages and I could clearly see that the CUSE thread exits
before it was requested to exit in cuse_nvme_ns_stop().
If the poller thread early-exits, it would destroy its own FUSE session
(and free the memory) before fuse_session_exit() gets executed, causing
the memory to be corrupted with a single byte of value 0x1.
Reproducer:
The bug can be reproduced by resetting the FUSE session to NULL after it
is destroyed. This will cuse_nvme_ns_stop() to crash with a segmentation
fault in fuse_session_exit() because it tries to access a NULL pointer.
static void *
cuse_thread(void *arg)
{
[...]
free(buf.mem);
fuse_session_reset(cuse_device->session);
+ cuse_device->session = NULL;
pthread_exit(NULL);
}
This fix:
The fix I suggest is to destroy the FUSE session with
cuse_lowlevel_teardown() after the thread is joined.

state is changed to NVME_QPAIR_DESTROYING and
transport's ctrlr_delete_io_qpair callback is
called. RDMA and TCP transports call
nvme_transport_ctrlr_disconnect_qpair in
the callback and since qpair's state is
not DISCONNECTED or DISCONNECTING, qpair
is disconnected for the second time.
If spdk_nvme_ctrlr_free_io_qpair is called
when qpair is in ENABLED state than nothing
changes, qpair will be disconnected before destroy.
PCIE/vfio_user don't implement transport disconnect
callback, so they are not affected.

in `spdk_nvme_ctrlr_free_io_qpair`, we will abort the outstanding
IO requests first, then in the `nvme_pcie_ctrlr_delete_io_qpair`,
we will poll the CQ for any requests that have been completed by

we will finish them again, thus double completions happened.
Here we rename `nvme_qpair_abort_reqs` to `nvme_qpair_abort_all_queued_reqs`,

For live migration support in vfio-user transport, we need to pause
the subsystem when starting migration in source VM, then after
migration, the subsystem is in paused state, when exiting the
application, we will call spdk_nvmf_subsystem_stop() at last,
and existing code will assert this case.

The recent changes merged multiple Data-OUT PDUs within the same
sequence into a single subtask up to 64KB.
However, they were not enough.
For a large write operation, the hardware iSCSI HBA host sent an immediate
data whose size was not block size multiples and then more solicit
data through R2T exchanges.
One example for a 64KB write operation was as follows:
host sent SCSI Write with 5792 bytes and F = 1
target replied a R2T
host sent Data-OUT with 15880 bytes
host sent Data-OUT with 11536 bytes
host sent Data-OUT with 2848 bytes
host sent Data-OUT with 11536 bytes
host sent Data-OUT with 5744 bytes
host sent Data-OUT with 12200 bytes and F = 1
The hardware iSCSI HBA host can decide the size of the unsolicited data
but the SPDK iSCSI target can require the host to send the solicited data
whose size is block size multiples.
Hence we merge immediate data to the following R2T data if the immediate
data is not more than 64KB and more R2T data come.
Add another test case to check if the fix works for the above example.

In the bdev-zone API, there are a few functions that takes a zone_id:
spdk_bdev_get_zone_info(), spdk_bdev_zone_management(), and the
spdk_bdev_zone_append() functions.
The way a zoned application is usually written is that it starts off
by getting the zone report for all zones (zone_id will be sent in as 0),
and then the application will keep the whole zone report in memory.
Therefore, an application usually have access to the zone_id/zslba for
all zones. However, there are cases, e.g. when getting an error on write,
where the completion callback will only have the lba of the write that
failed.
Add a helper function that can be used to get the zone_id/slba for a
given lba. Having this helper in bdev-zone will avoid SPDK applications
needing to provide their own implementation for this.

DPDK vhost will call `new_device` when the VRINGs are
queue paired(virtio-net) or all the VRINGs are started.
However, for virtio-blk/scsi, SeaBIOS will only use one
VRING queue, DPDK added a workaround patch to add
`pre_msg_handle` and `post_msg_handle` callbacks to let
devices other than virtio-net to process such scenarios.
In SPDK, we will start the device when there is one valid
VRING, so there is a case that SPDK and DPDK have different
state for one device. For a virtio-scsi device, SeaBIOS will
only start the request queue, and in the BIOS stage, SPDK will
start the device but DPDK doesn't think so. If users killed
SPDK vhost target at the moment, in `session_shutdown`, SPDK
will expect DPDK to call `destroy_device` to do the cleanup,
but DPDK won't do that as it thinks the device isn't started.
Here in `session_shutdown`, SPDK will do this first, it's OK
that DPDK will call another `destroy_device` for devices that
have the same state both in SPDK and DPDK.
Fix issue #2228.

The qpair's state member is only 3 bits of a uint8_t,
and the in_completion_context bit is another bit in that
same uint8_t.
We know that the qpair's state is only ever updated by
one thread, but it is possible that the state could
be modified by one thread, while another thread
is modifying in_completion_context.
in_completion_context is only modified by the thread
that is polling the qpair (or the qpair's poll group).
But with async mode, another thread that has a qpair
on the same PCIe controller could poll its adminq and
reap the SQ completion for the qpair that's owned by
the other thread.
So do *not* set the generic qpair state to CONNECTED
from the SQ completion callback. Instead just set
the pcie_state to READY, and let the thread that owns
the qpair detect the qpair is READY and set the state
to CONNECTED itself.

poll_group_update_subsystem we may get heap-use-after-free error
Another problem is that some qpair's live time may exceed controller's
life time. To avoid it, start controller destruction process when the last
qpair finished the disconnect process (previously controller started
the descruction process before the last qpair starts to disconnect
and it could lead to raise conditions)

There could be an outstanding for_each_reactor operation
in progress when the application shuts down. If we don't
wait for that operation to complete, we'll get a memory
leak for its context.
So when stopping the reactors, before setting the
state to EXITING, do one final for_each_reactor to
ensure any outstanding for_each_reactor operations are
flushed. Once this final for_each_reactor operation
is complete, we can set the state to EXITING safely.
Also use a global mutex and flag to ensure no more
for_each_reactor operations can start while the final
for_each_reactor is in progress. If a new operation
is requested, we'll just ignore since the reactors are
shutting down anyways.

This patch introduces the SW Eninge Channel and always initializes there
in case that HW Engine does not support some operations.

This change aims to help with tracepoint handling in the future.
Instead of printing each trace directly with given values, we
will use this function to pass status change value.

Previous patches (5363eb3c) tried to work around the
32-bit unmap and write_zeroes LBA counts by breaking
up larger operations into smaller chunks of max size
UINT32_MAX lba chunks.
But some SSDs may just ignore unmap operations that
are not aligned to full physical block boundaries -
and a UINT32_MAX lba unmap on a 512B logical /
4KiB physical SSD would not be aligned. If the SSD
decided to ignore the unmap/deallocate (which it is
allowed to do according to NVMe spec), we could end
up with not unmapping *any* blocks. Probably SSDs
should always be trying hard to unmap as many
blocks as possible, but let's not try to depend on
that in blobstore.
So one option would be to break them into chunks
close to UINT32_MAX which are still aligned to
4KiB boundaries. But the better fix is to just
change the unmap and write_zeroes APIs to take
64-bit arguments, and then we can avoid the
chunking altogether.
Fixes issue #2190.
