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().

Hyper-V NVMe SSD controllers require admin queue
size to be even multiples of a page. Add quirk to
adjust the admin queue size if user overrides the
default value to something other than an even
multiple.
As part of this change, set the quirks earlier
when constructing a pcie controller, so that the
quirks value can be used in the generic
nvme_ctrlr_construct() function.

Other libraries that don't support it will often fail on mempool

vague and don't indicate why this happened. So, this patch adds a check

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.

save the pid in the nvme_register_completion structure
when it is inserted into the STAILQ, then only complete
operations where the pid matches.

Various opts structures in SPDK have a size member, to enable
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
field added may just consume some of that padding.
So add STATIC_ASSERTS for the current sizes in this
patch. Upcoming patches will make the structures packed
and add in reserved fields to fill in holes.

Wait for all bdevs to finish examination before
proceeding with the spdk_bdev_finish shutdown

modules are not trying to examine bdevs after
the bdev layer has reported it has shut down.
Theoretically, bdev modules could all defer their
fini callbacks until any outstanding examinations
are complete, but it is WAY simpler to just use
the existing spdK_bdev_wait_for_examine API

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

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

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.

To minimize the impact, and to prevent these going on,
we add check the error return for creating NULL mempool

Parameter `num_queues` for virtio_scsi PCI device means
maximum number of queues, it SHOULD include the `eventq`
and `controlq`, while for `vhost_user` RPC call, it means
the number of IO queues, so here we use it as `max_queues`
in lib/virtio and add the fixed number queues for `vhost_user`
SCSI device.
Also fix `vhost_fuzz` to get `num_queues` earlier than
negotiate the feature bits.

here we merge vhost_user.c and virtio_user.c into one new source

While running into this function, even the subsystem can't be
destroyed due to error subsystem state, it's better to continue
the execution.
Continue to fix#2590, QEMU is stuck for the failure case, and
nvmf target should process such error because it may support other
normal subsystems at the same time.
