When doing live migration the migration BAR region is bytes stream

state into the stream in source VM and load it as internl data
structure from steam in destination VM.

There is a race condition between controller destruction and

when a namespace is added or removed. As result in function
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)

This patch is first in series that reworks vhost library

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.

We will assign each SQ with different poll group in round
robin way by default, this may cause race condition to
post completions to one CQ in different threads, so here
we will assign the SQs which share one CQ into same poll
group.
Also enable multiple cores NVMe compliance tests so that
to cover shared IO CQ case.

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.

Modify admin passthru so that result field of passthru struct is always

command specific info. This is specifically meant for the namespace
management command when attempting to create a namespace. As per spec:
"Dword 0 of the completion queue entry contains the Namespace Identifier
created.". So for nvme cli and perhaps other application to see what is
the id of the namespace created there needs to be a way to pass the

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.
