This is the beginning of support for external snapshots. An external
snapshot is a read-only blobstore device (struct spdk_bs_dev) that can
be used as a blob's back device. Normally a blob will have no back
device (a normal blob), a zeroes back device (a thin provisioned blob),
or a blob back device (a clone blob). When a blob has an external
snapshot ("esnap") as its back device, it is called an esnap clone.
With this patch, esnap clones can be created but they are not yet
useful. Subsequent patches in the series will plumb the IO path, enable
various features, and allow lvol bdevs to be esnap clones.

This is the port of the vbdev compress logic into the accel
framework. It includes just one enhancement, to only fill each
mbuf in either src or dst array with max "window size" param to
avoid QAT errors. Note that DPDK ISAL PMD was not ported as we
have native ISAL compression in accel now.
Note: ISAL w/DPDK is still built w/this patch, that can't be
removed until the vbdev module moves to accel fw as it still
depends on DPDK ISAL PMD.
Follow-on patches will include addition C API for PMD selection,
this patch just gets equivalent functionality going. Upcoming
patches will also convert the vbdev compress module to use the
accel framework instead of talking directly to compressdev.
More patches will also address comments on vbdev common code
that addressed here would make the review challenging.
This patch also fixes a bug in the ported code that needs to
be fixed here to pass CI. Capability discovery was incorrect
causing all devices to appear to not support chained mbufs,
with the mbuf splitting code this is important to get right.

LLVM provides libFuzzer which does coverage-guided
fuzzing of a library or application under test. For
SPDK, we can use this as a new and better way to
generate random commands to the SPDK nvmf target.
By default, libFuzzer provides the main() and your
source file just provides the function called by
LLVM for each iteration of random data. But this
doesn't really work for SPDK since we need to start
the app framework and the nvmf target. So we
specify -fsanitizer=fuzzer-no-link, explicitly
specify the location of the fuzzer_no_main library
and then call LLVMFuzzerRunDriver to start the
fuzzing process once we are ready.
Since this is all coverage-guided, we invoke the
fuzzer inside the nvmf target application. So this
patch creates a new target application called
'llvm_nvme_fuzz'. One core is needed to run the
nvmf target, then we spawn a pthread to run the
fuzzer against it.
Currently there are two fuzzers defined. Fuzzer 0
does random testing of admin commands. Fuzzer 1
is focused solely on GET_LOG_PAGE and fuzzes a
smaller subset of the bytes in the spdk_nvme_cmd.
Additional fuzzers can be added in the future for
other commands, testing I/O queues, data payloads,
etc.
You do need to specify CC and CXX when running
configure, as well as specify the location of the
special clang_rt.fuzz_no_main library. The path of
that library is dependent on your clang version and
architecture. If using clang-12 on x86_64 platform,
it will look like:
CC=clang-12 CXX=clang++-12 ./configure --with-fuzzer= \
/usr/lib/llvm-12/lib/clang/12.0.0/lib/linux/libclang_rt.fuzzer_no_main-x86_64.a
Then just do the following to demonstrate the fuzzer
tool.
make
test/nvmf/target/llvm_nvme_fuzz.sh --time=60 --fuzzer=0

Without this patch, we can use userspace idxd driver
under accel_engine library (module/accel/idxd/accel_engine).
With this patch, we can also kernel idxd driver under the

Our approach is implementing a wrapper library to use IDXD
device by leveraging the kernel DSA driver in SPDK idxd library
(lib/idxd).
Then users can leverage the RPC later to configure how to
use the DSA device by user space driver or kernel driver.
In this patch, our approach is to use the idxd-config library
to export the WQs (Working Queues) exported by the kernel.

This patch introduces initial definitions for a stripped down version of
an out-of-tree NVMe driver. It's purpose is to showcase SPDK's
interfaces for writing user-space drivers for various types of devices.
The choice of NVMe as the example is based on the fact that it can be
emulated by QEMU and the code can be borrowed from SPDK's regular NVMe
driver.
This driver will only provide the most basic functionalities (e.g.
device probing, controller initialization, only admin queue support,
etc.) and won't have support for any device quirks. Therefore, it's
only intented to be used with emulated devices.
In addition, an application utilizing the driver to list all available
NVMe controllers and print their identify data will be added. It'll
be a very basic, stripped down version of `examples/nvme/identify`.
