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.

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.

vhost: add a library and app for userspace vhost-scsi processing This patch adds a library, application and test scripts for extending SPDK to present virtio-scsi controllers to QEMU-based VMs and process I/O submitted to devices attached to those controllers. This functionality is dependent on QEMU patches to enable vhost-scsi in userspace - those patches are currently working their way through the QEMU mailing list, but temporary patches to enable this functionality in QEMU will be made available shortly through the SPDK github repository.

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 22.05 release. This patch: - increases SO_VER by 1 for all components - resets SO_MINOR to 0 for all components - removes suppressions for ABI tests Signed-off-by: Tomasz Zawadzki <tomasz.zawadzki@intel.com> Change-Id: Id1a5358882dc496faa5b0b5c9a63b326c378c551 Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/11361 Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Community-CI: Broadcom CI <spdk-ci.pdl@broadcom.com> Reviewed-by: Jim Harris <james.r.harris@intel.com> Reviewed-by: Ben Walker <benjamin.walker@intel.com>

lib/vhost: rename rte_vhost_compat to rte_vhost_user For some time already the DPDK rte_vhost interface was accomodating for other types of devices than virtio-net. rte_vhost_compat.c file contained the use of DPDK rte_vhost, rather than workarounds. To make that clear it is now renamed to rte_vhost_user.c. This patch is first in series that reworks vhost library with two goals in mind: 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.

configure: add option not to use the internal rte_vhost copy It's disabled by default, so no functionality is changed yet. The intention is to use the upstream rte_vhost from DPDK, which - starting from DPDK 19.05 - is finally capable of running with storage device backends. SPDK still requires a lot of changes in order to support that upstream version, but the most fundamental change is dropping vhost-nvme support. It'll remain usable only with the internal rte_vhost copy and with the upstream rte_vhost it simply won't be compiled. This allows us at least to compile with that upstream rte_vhost, where we can pursue adding the full integration.
