3359bf34d6 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the future releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 23.05
release.
Looks like this was left over from prior LTS, to avoid that
make sure it is only skipped when running against v23.01.x as latest
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests


Short reference to how the versions were changed:
MAX=$(git grep "SO_VER := " | cut -d" " -f 3 | sort -ubnr | head -1)
for((i=$MAX;i>0;i-=1)); do find . -name "Makefile" -exec \
	sed -i -e "s/SO_VER := $i\$/SO_VER := $(($i+1))/g" {} +;  done
find . -name "Makefile" -exec \
	sed -i -e "s/SO_MINOR := .*/SO_MINOR := 0/g" {} +

a6dbe3721e update Intel copyright notices
per Intel policy to include file commit date using git cmd
below.  The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc).  Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line.  Simply there for
consistency.

d14afd5000 bdev: Add copy IO type
Copy operation is defined by source and destination LBAs and LBA count
to copy. For destiantion LBA and LBA count we reuse exiting fields
`offset_blocks` and `num_blocks` in `struct spdk_bdev_io`. For source
LBA new field `src_offset_blocks` was added.

`spdk_bdev_get_max_copy()` function can be used to retrieve maximum
possible unsplit copy size. Zero values means unlimited. It is allowed
to submit larger copy size but it will be split into several bdev IOs.

48ce2c978e Bdev: remove the QD poller at the time of Bdev unregister
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.

488570ebd4 Replace most BSD 3-clause license text with SPDX identifier.
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.

b7ad5b0b90 bdev/zone: add support for get zone id
In the bdev-zone API, there are a few functions that takes a zone_id:
spdk_bdev_get_zone_info(), spdk_bdev_zone_management(), and the
spdk_bdev_zone_append() functions.

The way a zoned application is usually written is that it starts off
by getting the zone report for all zones (zone_id will be sent in as 0),
and then the application will keep the whole zone report in memory.

Therefore, an application usually have access to the zone_id/zslba for
all zones. However, there are cases, e.g. when getting an error on write,
where the completion callback will only have the lba of the write that
failed.

Add a helper function that can be used to get the zone_id/slba for a
given lba. Having this helper in bdev-zone will avoid SPDK applications
needing to provide their own implementation for this.

6cebe9d06b nvmf: Support physical block size if exposed by bdev
(Note: this patch was previously applied as b32cfc46 and then reverted
as 63642bef.)

Today the in-guest nvme device shows physical_block_size=512 even though
the backend iSCSI bdev supports physical_block_size=4K

iSCSI targets exposes physical block size using
logical_block_per_physical_block_exponent in READ_CAPACITY_16

NPWG is one of the way to let Linux nvme driver set
physical_block_size of the nvme block device.

This patch adds spdk_bdev.phys_blocklen which is updated if the iSCSI
backend exposes physical_block_size.
Later phys_blocklen is used in nvmf to set NPWG and NAWUPF to report
back during NS identity.
Linux driver uses min(nawupf, npwg) to set physical_block_size.

Similarly in scsi_bdev fill lbppbe in READ_CAP16 response
based on spdk_bdev.phys_blocklen.

Fixes #1884

There was a change to the spdk_bdev_opts struct
which is accessible from the public API that results
in an ABI change.

There was also a change in the spdk_accel_module_if struct that
will affect new modules so its major version needs to be revved.

There was also a change in the publically accessible rmda_hooks
structure which forced an ABI change in the NVMe library.

aa35048d15 lib/bdev: Zoned bdev public header
Added new public header for zoned bdev. Zoned bdev is an
extension of the bdev interface. Generic concept comes
from ATA/SCSI and is also being worked as an NVMe TP.

Zoned device logical blocks space is divided into fixed-sized
zones. Each zone is described by its start logical block address
and capacity. Writes to a single zone need to be sequential.
After zone is fully written it need to be reset to write to it
again. Such writing schema could be very beneficial in terms of
write amplification factor for NAND based devices.
SPDK Flash Translation Layer library will be consuming this
interface in the future.

Extending SPDK bdev interface will allow to use existing bdev
infrastructure for this new type of devices.

Zoned device have several properties defined in spdk_bdev
structure:
 - zone_size: default size of each zone
 - max_open_zone: maximum number of open zones
 - optimal_open_zones: optimal number of open zones to get
		       best performance on writes

Single zone properties are defined in spdk_bdev_zone_info
structure:
 - start_lba: first logical block of z zone
 - write_pointer: logical block address in the zone at
		  which next write shall occur.
 - capacity: maximum number of logical blocks that may
	     be written in the zone when zone is empty.
 - state: zone state

Several zone states are defined: Empty, Open, Full, Closed,
Read Only and Offline.

To change zone state zone actions are defined: Close, Finish,
Open and Reset.

d1fee489a7 OCF: add OCF module
Add OCF module based on OCF meta-library
Open CAS Framwework (OCF) is high performance block storage
  caching meta-library
It is open-source, published at https://github.com/Open-CAS/ocf

With this patch OCF-enabled device is represented in SPDK
  as virtual bdev having core and caching devices as its base devices

This patch includes implementation of:
  * OCF top adapter          (vbdev_ocf.c)
  * OCF bottom adapter       (dobj.c, data.c)
  * Adaptation layer for OCF (env/)
  * OCF context abstractions (ctx.c)

Adaptation layer and context abstractions are not dependent on SPDK bdev

OCF bdev supports reads and writes, configured at startup
Other features will be added with separate patches

1d64773c2a raid: enable by default
We kept this disabled by default originally because it lacked
multiple iov support needed for vhost and nvmf in-capsule data.
Now that support has been added, there is no reason to not
enable it automatically - it has no extra package dependencies,
so requiring users to specify --with-raid to configure is just
an extra unneeded step.

51606ed402 bdev: Add crypto virtual bdev module
Initial support for softare AESNI_MB DPDK driver only.

Have tested (both aesni and QAT seprately and concurrrently) on underlying NVMe devices
with bdevio and a bdevperf script that runs IOs from 512B to 128K each with Q depths from
1 to 512 in powers of 2 for 30 seconds each run.

QAT can be included in the code (but not makefile) and marked as experimental
until we are ready to test in CI.  It works well on 2 systems but is a big PITA to get
the hardware setup and configured for use with DPDK (IMHO).

41586b0f1d bdev: add raid bdev module
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

c2175d2c51 virtio: add initial rev of virtio-scsi initiator bdev module
Supports both PCI mode (for usage in guest VMs) and
vhost-user mode (for usage in host processes).  The rte_virtio
subdirectory contains a lot of code lifted from the DPDK
virtio-net driver.  Most of the PCI and vhost-user code is
reused almost exactly as-is, but the virtio code is drastically
rewritten as the DPDK code was very network specific.

Has been lightly tested with both the bdevio and bdevperf
applications in both PCI and vhost-user modes.

Still quite a bit of work needed - a list of todo
items is included in a README in the module's directory.
