e1b5d28c8b bdev/nvme: set max_segment_size and max_num_segments
Maximum Data Transfer Size indicates the maximum data transfer size
for a command that transfers data between memory and the controller.
SPDK NVMe driver will split IO request based on MDTS and stripe
boundary, however, if user submited a big enough IO size, SPDK
NVMe driver will run out of requests data structure and return
-EINVAL as the error code, it's OK for application who call SPDK
NVMe driver directly.

SPDK bdev module also will do similar split based on `max_segment_size`
and `max_num_segments`, but we don't set them for bdev/nvme driver,
once there was a big enough IO request, the NVMe driver will return
-EINVAL to bdev module, here we set `max_segment_size` based on MDTS
and set `max_num_segments` based on number of requests of NVMe
controller.

Fix #2403.

fcf52fbff5 bdev/nvme: Reversed orderings for reset between PCIe and NVMe-oF
As described in the NVMe specification, a controller level reset
includes the following actions:
- the controller stops processing any outstanding admin or I/O
  commands;
- all I/O SQs and CQs are deleted.

In a full controller reset sequence for a PCIe controller, if we do
a controller level reset first, we can abort outstanding commands
after the hardware has actually been stopped.

For NVMe-oF controller, each I/O qpair is an independent network
connection and is disconnected safely. We do not want to change
NVMe-oF controller.

Fixes the issue #2360

09c7c76876 nvme: Set I/O qpairs to failed only if reset is synchronous
For PCIe transport, we need to stop any activity of the controller
before deleting I/O qpair resource in a controller reset sequence.

However, we set I/O qpairs to failed before disabling a controller.
In the NVMe bdev module, this caused disconnected qpair callback to
delete I/O qpairs before disabling the controller.

Hence, change the code slightly to set I/O qpairs to failed only if
reset is synchronous to keep backward compatibility.

16cc2ade5d sma: QMP base definitions created
This patch adds python scripts for basic handling of QEMU Machine
Protocol connection for use with vfio_user. Basic low-level connection
and error handling added as extended socket class.
QMPClient: Wrapper class for handling connection with QMP was added.

Protected class method _receive relies on the fact, that QMP always
sends command 'in one line' - each one is always terminated with CRLF.
https://github.com/qemu/qemu/blob/master/docs/interop/qmp-spec.txt

Usage example, command line calls:
1) Without event parameter:
```json
{
    "request": {
        "execute": "device-list-properties",
        "arguments": {
            "typename": "vfiouser-0-1-1"
        }
    }
}
```
2) With event parameter specified. Specifying 'event'
parameter will set script to block wait for occurrence
of such one after a valid execution of specified request:
```json
{
    "event": {
        "event": "DEVICE_DELETED",
        "data": {
            "device": "vfiouser-0-1-1"
        }
    },
    "request": {
        "execute": "device_del",
        "arguments": {
            "id": "vfiouser-0-1-1"
        }
    }
}

943088499b sma: add volume cleanup thread
Since SMA keeps track of attached volumes and a volume might get
disconnected at any time (in which case they're also removed from the
host side), a mechanism is needed to monitor if any of the volumes are
no longer accessible.

This patch implements that mechanism by adding a new thread running in
the background that will periodically (60s by default) send a
bdev_get_bdevs RPC and check that all previously attached volumes are
available.  If any of them are not, it'll remove it and stop the
associated discovery services (if their refcount goes down to zero).
The period can be changed through the `volume_cleanup_period` variable
in the config file.

One important thing to note is that we assume that any intermittent
connection issues are handled internally by the SPDK application and a
bdev is only removed after all reconnection attempts are performed.

0c2b10f250 sma: initial support for volume connection via discovery
This patch adds support for connecting volumes via discovery service.
The user specifies a volume UUID/GUID and a list of discovery endpoints,
which are then used to start the discovery service on and attach the
volume to a device.

SMA will keep track of the attached volumes and will also refcount the
connections to discovery services.  So if two volumes are attached using
the same discovery endpoint, it'll be disconnected only after both of
them are detached.

b5678ba805 sma: wait until SPDK process is responding
Most of the devices need to send RPCs during initialization (e.g. create
a transport), so we need to take care that they're initialized only
after we are certain that the SPDK process is listening.

The mechanisim is similar to the `waitforlisten` function used in our
test scripts - it sends a series of `rpc_get_methods` calls and times
out after a period of time if no response is received.  For now, the
timeout is hardcoded to 60s.

that device manager.  For instance:

```

After finishing migration in source VM, the subsystem is in
PAUSED state, the controller is dead for the source VM, we will
destroy the controller when disconnecting socket, but after that,
we should RESUME the subsystem so that it can be ready for the
next new client.

9900e48d01 bdev/ocf: Update OCF to 21.6.3.1
This OCF update is mainly focused on:
- Fix OCF crash when handling flush I/O with large size

Previous implementation attempts to use cache data I/O interface
(ocf_submit_cache_reqs function) instead of submitting empty flush to
the underlying cache device. This function is designed to read/write
from mapped cachelines while there is no traversation/mapping
performed on flush I/O.
If request map allocation succeeds, this results in sending I/O to
addres 0 with size and flags inherited from the top adapter I/O.
This doesn't make any sense, and can even result in invalid I/O if the
size is greater than cache device size.
Even worse, if flush request map allocation fails (which happens
always in case of large flush requests) then the erroneous call to
ocf_submit_cache_reqs results in NULL pointer dereference.

Other fixes included in this OCF update:
- Fix race condition in fast path
- Fix use after free during metadata load
- Fix cleaner hung after cleaning policy switch
- Fix use after free during volume close
- Fix stack overflow when trying to insert to disabled io class
  and the sequential cutoff is on

dd474d0286 dpdkbuild: add DPDKBUILD_FLAGS variable
Some environments (such as a VM on my M1-based
MacBook Pro) report CPU with an Implementer+Part Number
that DPDK doesn't explicitly support.  In my case, it
is Implementer ARM (0x41) but no part number (0x0).
DPDK doesn't just default to a generic build in this
case, it requires the user to specify
-Dplatform=generic.

We could try to plumb this into a configure option,
but for now I'm fine in my dev environment to just
specify this DPDKBUILD_FLAGS in my environment to
work around it.

bdc9fa832d nvme: Add helper functions to do a Controller Level Reset (Set CC.EN to 0)
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
on each channel and remove dynamic memory allocation.

With this change blob_write_extent_page() expects

7bcd316de1 bdev: abort all IOs when unregistering the bdev
To fix issue: #2484

When unregistering the bdev, will send out the message
to each thread to abort all the IOs including IOs from
nomem_io queue, need_buf_small queue and need_buf_large queue.

The new SPDK_BDEV_STATUS_UNREGISTERING state is newly
added to indicate this unregister operation.

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:
  enomem_multi_bdev_unregister: to abort the IO from
nomem_io queue during the unregister operation
  bdev_open_ext_unregister: to handle the events and
async operations from the unregister operation

93a20e79ec sma: loading out-of-tree plugins
It's now possible to register SMA device managers defined in a module
outside of the regular directory.  To do that, a global variable called
`devices` containing a list of device manager classes needs to be defined
in a module that's added to SMA_PLUGINS environment variable.

For example:
```
$ cat /path/to/plugins/external_devices/__init__.py
import spdk.sma as sma

class MyDeviceManager1(sma.DeviceManager):
	pass

class MyDeviceManager2(sma.DeviceManager):
	pass

devices = [MyDeviceManager1, MyDeviceManager2]

$ SMA_PLUGINS=external_devices scripts/sma.py
```

Multiple plugins can be specified by separating them with a colon, e.g.:
```
SMA_PLUGINS=plugin1:plugin2
```
Of course, the location at which these modules reside must be in
PYTHONPATH.
