Following discussion in a recent SPDK community meeting,
it was determined that we no longer need to carry ISA-L as
a user configuration option. It will be enabled by default.
If running on an architecture that ISA-L isn't fully supported
on, the configure script will disable associated features and
display a warning and will also not build ISA-L. Same case if
there are issues with dependencies.
Note that --without-isal is no longer supported as a configure
option.

Previously we would always allocate the shm file based on
max (128) cores which is unnecessary. So use
spdk_env APIs to only allocate shm file size based
on the cores we might possible use.
With default settings, an shm file was 135MB before this
change, now an app using cores 0-7 will just use
about 9MB.
A lot of the trace-related code depended on there
*always* being a history for every core, even unused
ones, so a few additional changes were needed,
mainly the trace_parser library.
Tested by starting an app using a 0x4 core mask and
enabling a trace mask, generating some events, then
checking both the size of the shm file and that
spdk_trace works properly with the resulting file.

When doing live migration, there are some spdk_nvmf_ctrlr internal
data structures which need to be saved/restored, these data
structures are designed only for vfio-user transport, for
the purpose to extend them to support other vendor
specific transports, here we move them as public APIs,
users can use SAVE|RESTORE to restore a new nvmf controller
based on original one.
And remove the register from vfio-user transport, these registers
are stored in the common nvmf library.

operation an L2P page (containing 1024 4B entries, 1 per user LBA; which
is where the 4MiB alignment comes from) will be marked as unmapped.
After this point any L2P access to that page will actually set the
entries themselves as FTL_ADDR_INVALID. This is done to make the trim as

will allow for recovering both the P2L and write pointer of open bands
after a dirty shutdown. After writing 1MiB of data to a band, a 4KiB
block describing the P2L will be persisted to cache device, effectively
emulating VSS for the base device.

For non-fabric controllers, the corresponding I/O qpairs are simply
re-enabled at controller reset.
This had a issue when I/O qpairs span multiple threads and poll group
is used.
spdk_nvme_ctrlr_reconnect_poll_async() calls
nvme_transport_ctrlr_connect_qpair() with qpair->async being false.
Then nvme_transport_ctrlr_connect_qpair() calls
spdk_nvme_poll_group_process_completions() until the qpair is connected.
spdk_nvme_poll_group_process_completions() may poll other qpairs.
This may cause I/O to complete on a wrong thread.
For PCIe controller, spdk_nvme_poll_group_process_completions() calls
spdk_nvme_qpair_process_completions() simply for each qpair.
Hence change nvme_transport_ctrlr_connect_qpair() to call
spdk_nvme_qpair_process_completions() if the controller is non-fabrics.

Writing to unallocated cluster triggers copy-on-write sequence. If
this cluster is backed by zeroes device we can skip the copy part. For
a simple thin provisioned volume copy this shortcut is already
implemented because `blob->parent_id == SPDK_BLOBID_INVALID`. But this
will not work for thin provisioned volumes created from snapshot. In
this case we need to traverse the whole stack of underlying
`spdk_bs_dev` devices for specific cluster to check if it is zeroes
backed.
This patch adds `is_zeroes` operation to `spdk_bs_dev`. For zeroes
device it always returns 'true', for real bdev (`blob_bs_dev`) always
returns false, for another layer of `blob_bs_dev` does lba conversion
and forwards to backing device.
In blobstore's cluster copy flow we check if cluster is backed by
zeroes device and skip copy part if it is.

If initiator and target run on the same application, and initiator
uses SRQ, target may get async events for initiator, e.g.,
IBV_EVENT_QP_LAST_WQE_REACHED unexpectedly.
The reason is initiator and target may use the same device
simultaneously and only target polls async events.
Target sets attr.qp_context to rqpair when creating QP, but initiator
sets attr.qp_context to NULL when creating QP.
Hence one simple fix is to ignore async events whose qp_context is
NULL.

By the previous patches, a qpair is destroyed after it is actually
disconnected.
But after the qpair is destroyed, it is checked if drained by using
rqpair->current_num_sends and rqpair->current_num_recvs.
However, if the qpair is the last of a poller of a poll group,
CQ is destroyed before checking if the qpair is drained.
If CQ is destroyed, at least rqpair->current_num_recvs is not updated,
and we may get one second timeout.
This should be avoided.
Hence, destroy the qpair after it is disconnected and drained.

The primary motivation for this patch is to allow the VMD driver to be
notified of when users wants to attach a device under a given BDF and to
make it more similar to the regular PCI path. Currently, the way the
VMD driver scans for the devices is a little bit different. The initial
scan is done during initialization and there's a separate poller for
checking hotplugs. Also, there's no device_attach() interface, so with
hotplug poller disabled, it isn't possible to attach to a device not
present in the initial scan, even if the BDF is known.
This causes a few issues. First of all, the VMD library isn't notified
when a device is stopped being used (i.e. user calls
spdk_pci_device_detach()), so when such a device is hotremoved, it never
gets unhooked. But we cannot simply add a spdk_pci_device.detach()
callback, as this would break cases when user detaches a device (without
hotremove) and then tries to reattach it again (via
spdk_pci_device_attach()), as the VMD doesn't get notified about the
device_attach() call.
So, in order to resolve this, a device_attach() callback is added, which
will notify the VMD library that the user wants to attach a device under
a specific PCI address. Then, in subsequent patches, a
spdk_pci_device_provider.detach_cb() callback is added to make sure that
devices are unhooked once they're no longer used.
Once that is done, it'll be also possible to get rid of the VMD hotplug
poller by adding something like scan_cb() to spdk_pci_device_provider and
call it from spdk_pci_enumerate().

Multiprocess is only supported by a few libraries (e.g. NVMe driver).
Other libraries that don't support it will often fail on mempool
initialization when running as a secondary process, as the mempools are
already created by the primary process. But the error messages are
vague and don't indicate why this happened. So, this patch adds a check
to see if a mempool exists after spdk_mempool_create() fails and prints
an error message informing users that multiprocess is unsupported.

Commit a119799b ("test/nvme/aer: remove duplicated changed NS list log")
changed the nvme driver to read the CHANGED_NS_LIST log page before
calling the application's AER callback (previously it would read it
after).
Commit b801af090 ("nvme: add disable_read_changed_ns_list_log_page")
added a new ctrlr_opts member to allow the application to tell the
driver to not read this log page, and will read the log page itself
instead to clear the AEN. But we cannot add this option to the 22.01
LTS branch since it breaks the ABI. So adding this API here, which
can then be backported manually to the 22.01 branch for LTS users
that require it.
Restoring the old behavior is not correct for applications that
want to consume the CHANGED_NS_LIST log page contents itself to
know which namespaces have changed. Even if the driver reads the
log page after the application, that read could happen during a
small window between when a namespace change event has occurred and
the AEN has been sent to the host. The only safe way for the
application to consume ChANGED_NS_LIST log page contents itself
is to make sure the driver never issues such a log page request
itself.

This allows mapping an nvme_request back to the
nvme_bdev_io.
This requires bumping up the max number of arguments per
tracepoint. 5 was previously chosen as max since it
exactly fit in 64 bytes (1 cacheline) when all
arguments were stored as uint64_t, but now that we
support uint32_t arguments we can afford extra
arguments when some of them are uint32_t. I've
bumped it to 8 so we can avoid having to touch
this value multiple times if we find some cases
where we need 7 or 8 args.

This will allow us to map spdk_bdev_io events
to nvme_request events coming in a future patch.
Since we pass the nvme_bdev_io to the nvme driver
(not the spdk_bdev_io), we need to add tracepoints
for the nvme_bdev_io so that spdk_trace can
do the spdk_bdev_io->nvme_bdev_io->nvme_request
mapping.
An alternative would have been to pass the spdk_bdev_io
as the cb_arg to the nvme driver, but that change
seemed to invasive, and I think we will find other
uses for the nvme_bdev_io events anyways.

ABI compatibility should fields be added in the future.
But this requires the strucures to be packed, otherwise for
example a structure may be padded at the end, and a new

So add STATIC_ASSERTS for the current sizes in this
patch. Upcoming patches will make the structures packed

Get a PD for the device from the PD pool managed by the RDMA provider
when creating a QP, and put the PD when destroying the PD.
By this change, PD is managed completely by the RDMA provider or the hooks.
nvme_rdma_ctrlr::pd was added long time ago but is not referenced
anywhere. Remove nvme_rdma_ctrlr::pd for cleanup and clarification.

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.
Fixes issue #2631.

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.

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
of subsystem pause, because we cannot expect them
to be completed. Previously we would account for this
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

read the 4 bytes for the pdu in target, the io request complete

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,
so do that in nvme_tcp_req_complete as well.

Fix issue: #2561
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
be handled properly.
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.

have the return type on a separate line. Astyle has an option for

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
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

We need to synchronize with each poll group via a message before we can
call vfu_device_quiesced(), otherwise we could still be processing

For interrupt mode, we then might miss processing commands in a
corresponding interrupt callback, so make sure we process them when we

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.

a callback to particular virtio-blk transport.
Having this piped through to the transports, allows
to adjust their behavior upon bdev events.

There are configuration details that are needed to configure
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
or supported I/O type.
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.

Since we may have only 1 outstainding cluster
allocation per io_channel, we can preallcoate md_page

With this change blob_write_extent_page() expects

In this case, the bdev unregister operation becomes the
async operation as each thread will be sent the message
to abort the IOs and as the last step, it will unregister
the required bdev and associted io device.
On the other hand, the queued_resets will be handled
separately and not aborted in the bdev unregister.
New unit test cases are also added:

nomem_io queue during the unregister operation
bdev_open_ext_unregister: to handle the events and

event from rdmacm to destroy rdma resources. However
the user (nvme_perf) can destroy qpair immediatelly,
so memory allocated for qpair is freed but rdma
resouces are still allocated. That means that we may
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
when qpair is destroyed, if disconnect is not finished, then
we forcefully destroy rdma resources.
