The 4 different RPC commands to create Virtio bdevs
have been unified to a single, yet another RPC command
in hopes the previous ones will be eventually removed.
That happened in 18.07 and now in order to remove the
old ones we mark them deprecated.
The unified RPC command was introduced in 18.07 and
has already replaced the old, separate RPCs in our
test scripts some time ago.
This patch also removes the old RPCs from doc/bdev.md
and while here, rephrases the Virtio section a bit to
make it more readable after some alphabetization
changes from the past.
jsonrpc.md already described the old RPCs as about to
be deprecated, so there are no changes required in
there.

QAT can be included in the code (but not makefile) and marked as experimental

Loading CHAP secret file is done by default and this will conflict to

Hence the path to CHAP secret file is required to specify in the config
file or JSON RPC set_iscsi_options explicitly after this patch.
Users who have used CHAP secret file are expected to specify it explicitly
and this will be no harm for them.
Besides, CHAP secret file is not oly for discovery sessions but also for
login to iSCSI targets. However there were wrong description to make user

correspondingly to do so. This includes the single, combined
shared library encompassing all of the SPDK static libs,
as well as production of individual SPDK shared libraries
corresponding to each of the static ones. Although the
SPDK shared libs conform with shared lib naming conventions
complete with version numbering suffixes, this does not
confer any ABI compatibility claims whatsoever at this time.
It's merely conformance with the naming conventions.
Finally, there are no built-in dependencies between SPDK
shared libs, thus requiring one to specify all needed SPDK
shared libs to resolve all symbols in the final link of an
executable wishing to use said SPDK shared libs.

Also added is a configure option '--with-crypto' and the associated

The crypto vbdev patch will use this same configure option to determine
DPDK opts as well as whether the crypto vbdev should be built or not.

Raid module:
============
- SPDK raid bdev module is a new bdev module which is
responsible for striping various NVMe devices and expose the raid bdev
to bdev layer which would enhance the performance and capacity.
- It can support theoretically 256 base devices (currently it is being
tested max upto 8 base devices)
- Multiple strip sizes like 32KB, 64KB, 128KB, 256KB, 512KB etc is
supported. Most of the current testing is focused on 64KB strip size.
- New RPC commands like "create raid bdev", "destroy raid bdev" and "get raid bdevs"
are introduced to configure raid bdev dynamically in a running
SPDK system.
- Currently raid bdev configuration parameters are persisted in the
current SPDK configuration file for across reboot support. DDF will be
introduced later.
High level testing done:
=======================
- Raid bdev is created with 8 base NVMe devices via configuration
file and is exposed to initiator via existing methods. Initiator is
able to see a single NVMe namespace with capacity equal to sum of the
minimum capacities of 8 devices. Initiator was able to run raw
read/write workload, file system workload etc (tested with XFS file
system workload).
- Multiple raid bdevs are also created and exposed to initiator and
tested with file system and other workloads for read/write IO.
- LVS / LVOL are created over raid bdev and exposed to initiator.
Testing was done for raw read/write workloads and XFS file system
workloads.
- RPC testing is done where on the running SPDK system raid bdevs
are created out of NVMe base devices. These raid bdevs (and LVOLs
over raid bdevs) are then exposed to initiator and IO workload was
tested for raw read/write and XFS file system workload.
- RPC testing is done for delete raid bdevs where all raid bdevs
are deleted in running SPDK system.
- RPC testing is done for get raid bdevs where existing list of
raid bdev names is printed (it can be all raid bdevs or only
online or only configuring or only offline).
- RPC testing is done where raid bdevs and underlying NVMe devices
relationship was returned in JSON RPC commands

This is the first step toward fixing the behavior of the lvol bdev
module so that it handles spdk_bdev_unregister() correctly.
Currently, when an lvol bdev is unregistered, this causes the associated
lvol to be deleted; this isn't the desired behavior, since
spdk_bdev_unregister() is just meant to drop the currently-exposed bdev,
as in a hot-unplug event, not destroy the backing storage.
The current implementation of the new destroy_lvol_bdev method still
calls into the exsting (broken) spdk_bdev_unregister() path, but this at
least lets us fix the existing delete_bdev RPC callers that really
intended to destroy the lvol.
The next step is to make vbdev_lvol_destroy() call spdk_lvol_destroy()
instead of unregistering the bdev, which will require cleanup in the
generic lvol layer to remove the close_only flag.

Using the ** paradigm is a bit problematic for asynchronous
routines that could fail. Currently we were inconsistent in
that some error paths would zero the pointer while others
did not. So make this just a plain pointer, which simplifies
the API and its implementation.

RPC is a default feature required for almost all usages,
so enable RPC by default, but with a UNIX domain socket
for security reasons.
-r can now be used from the command line to specify
an alternative RPC listen address from the default
/var/tmp/spdk.sock.
Remove the Enable parameter from the Rpc config section
but still allow specifying an alternative listen address
using the Listen parameter as an alternative to the
command line option. This keeps backward compatibility
for this release for anyone using the configuration file
still.
Remove the Rpc sections from all configuration files
that were using them, except for those that specified
alternate TCP ports for multi-process test cases. We
can fix these later to use an alternate UNIX domain
socket and to use the command line instead.

Previously, the shared buffer pools were allocated on the
nvmf controllers. When a new connection was established,
the CONNECT command needs a 4k buffer, but we didn't know
which nvmf controller it belonged to until after the
CONNECT command completed. So there was a special case
for CONNECT that used in capsule data buffers instead.
Now, the buffer pool is global and always available. We
can just use that always, with no more special cases.
This has the additional nice side effect of allowing
users to run the target with no in capsule data buffers
allocated at all.

It is also more consistent with the normal non-SGL NVMe functions that

The previous method for registering I/O queues did not allow the user
to specify queue priority for weighted round robin arbitration, and it
limited the application to one queue per controller per thread.
Change the API to require explicit allocation of each queue for each
controller using the new function spdk_nvme_ctrlr_alloc_io_qpair().
Each function that submits a command on an I/O queue now takes an
explicit qpair parameter rather than implicitly using the thread-local
queue.
This also allows the application to allocate different numbers of
threads per controller; previously, the number of queues was capped at
the smallest value supported by any attached controller.
Weighted round robin arbitration is not supported yet; additional
changes to the controller startup process are required to enable
alternate arbitration methods.
