05dce1ee78 nvme: don't try to enable intel log pages on fabrics ctrlrs
By default, the SPDK nvmf target reports vid==INTEL,
which results in the SPDK nvme driver trying to enable
Intel vendor-specific log page.  Fix this by trying to
enable those log pages only for PCIE transport
controllers.

988ce2ecaa nvme: use assert for INTEL_VID check on log pages
We can only get to this code path if the controller
has vid==INTEL, so make that more clear by changing
the check to an assert.

Remove unit test that calls
nvme_ctrlr_construct_intel_support_log_page_list()
for a controller that is not VID==INTEL - this is
no longer valid.

4be6d30438 nvme: Add ctrlr_abort_queued_aborts() into qpair_abort_all_queued_reqs()
nvme_qpair_abort_all_queued_reqs() aborts error injections, queued
requests, aborting queued requests, and outstanding requests. (Aborting
outstanding requests depends on transports.) However, it did not abort
queued aborts.

Include nvme_ctrlr_abort_queued_aborts() into
nvme_qpair_abort_all_queued_reqs() to do really the name of the
function indicates.

nvme_ctrlr_abort_queued_aborts() has been called in a few cases, but
we do not care duplication.

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.

8dd1cd2104 check_format: For C files only, fix return type breaks
In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:

1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names

Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

0b9100e8a5 bdev/nvme: replace nn with mnan in ana_log size calculation
Calculation of the ANA log page size should use the
identify ctrl MNAN field
(maximum number of allowed namespaces)
not the NN (maximum valid nsid value).

An ANA-enabled controller must have a non-zero MNAN value,
see NVMe Base Specification, Figure 251,
therefore nvme_ctrlr_init_ana_log_page() may safely use MNAN.

Since NN might be much higher than MNAN,
ANA log size based on NN may results in a very large
log page and cause a failure to get ANA log,
e.g. if it is larger than the controller's MDTS.

Fix: replace cdata->nn with cdata->mnan
in nvme_ctrlr_init_ana_log_page()

6e9cf0c7b4 test: add ENV_CFLAGS after includes
DPDK CFLAGS get put into CFLAGS in mk/cc.flags.mk,
which for system package installed DPDK will include
extra paths like /usr/include/<arch-3-tuple>/dpdk.
If a Makefile adds its own CFLAGS before including
the .mk fragment that pulls in these CFLAGS, we won't
actually get those cc.flags.mk applied since they
are defined with ?=.

This may need to be revisited - using ?= for these
has evolved through several iterations of our SPDK
configured flag files - starting with commit
08ec96eb.  But for now, let's just fix these few
Makefiles.

Fixes issue #2548.

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.

b727e804d6 vhost: add virtio_blk abstraction
This patch adds virtio_blk abstraction for custom transports,
with the 'vhost_user_blk' first one being used.

Added spdk_virtio_blk_transport_ops describing the nessecary
callbacks to be implemented by each transport.
Please use SPDK_VIRTIO_BLK_TRANSPORT_REGISTER to register the transport.
Transports can use virtio_blk_process_request() to process the
incoming I/O from their queues.

virtio_blk_create_transport RPC was added to create one of the
registered transports, possibly with custom JSON arguments.

Added 'transport' argument to vhost_create_blk_controller RPC,
to specify which transport should create the controller.
By default the vhost_user_blk transport is used.

alloc_vdev() will require further changes to test both types

192e64bcc5 bdev: spdk_bdev_ext_io_opts missing size check
ext_io_opts uses the size member to allow backwards
compatibility however currently we only check if it is
below or equal the current size of the opts struct and
that it is not 0. size is only used when we copy opts
because of split or push/pull.
This patch introduces size checks to allow safe access
to e.g. metadata and memory domain pointers of the user
provided opts pointer. The minimum size of the struct
passed is now the size of the initial version of
spdk_bdev_ext_io_opts. To not introduce additional
checks when opts are consumed by a bdev module we
now always copy if the size is smaller than the
current opts struct size.
When introducing new members to opts additional
checks might be needed if those are directly accessed
through the passed pointer or bdev_io->internal.ext_opts.

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.

md_page is allocated to update extents in base dev
This memory allocation reduces perfromance, it can
take 250usec - 1 msec on ARM platform.

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
that md_page is given by the caller. Sicne this function
is also used during snapshot deletion, this patch also
updates this process. Now we allocate a single page
and reuse it for each extent in the snapshot.

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

* adding a submit_tasks() entry point for the SW engine so that

submit_tasks() to the assigned engine for the opcode instead of
checking what is supported

* changing the definition of engine capabilities from
"HW accelerated" to simply "supported"

* during init, use a global (g_engines_opc) that contains engines
and is indexed by opcode so we know what the best engine is for each
op code

* future patches will add RPC's to override engine priorities or
specifically assign an opcode(s) to an engine.

Different from active-passive, active-active caches even non_optimized

22b77a3c80 bdev/nvme: Set preferred I/O path in multipath mode
If we specify a preferred path manually for each NVMe bdev, we will
be able to realize a simple static load balancing and make the failover
more controllable in the multipath mode.

The idea is to move I/O path to the NVMe-oF controller to the head of
the list and then clear the I/O path cache for each NVMe bdev channel.
We can set the I/O path to the I/O path cache directly but it must be
conditional and make the code very complex. Hence, let find_io_path() do
that.

However, a NVMe bdev channel may be acquired after setting the preferred
path. To cover such case, sort the nvme_ns list of the NVMe bdev too.

This feature supports only multipath mode. The NVMe bdev module supports
failover mode too. However, to support the latter, the new RPC needs to
have trid as parameters and the code and the usage will be come very
complex. Add a note for such limitation.

To verify one by one exactly, add unit test.

MSG_ZEROCOPY or not according to its size, which can be enabled by
setting "enable_dynamic_zerocopy" as true.

For posix socket, rw_percent=0(randwrite), it has 1.9%~8.3% performance boost
tested with target 1~40 cpu cores and qdepth=128,256,512. And it has no obvious
influence when read percentage is greater than 50%.

For uring socket, rw_percent=0(randwrite), it has 1.8%~7.9% performance boost

2bc134eb4b bdev/nvme: Fix aborting fuse commands
When sending a fused compare and write command, we pass a callback
bdev_nvme_comparev_and_writev_done that we expect to be called twice
before marking the io as completed. In order to detect if a call to
bdev_nvme_comparev_and_writev_done is the first or the second one, we
currently rely on the opcode in cdw0. However, cdw0 may be set to 0,
especially when aborting the command. This may cause use-after-free
issues and this may call the user callbacks twice instead of once.
Use a bit in the nvme_bdev_io instead to keep track of the number of
calls to bdev_nvme_comparev_and_writev_done.

3056c8ac02 nvmf/tcp: delay qpair destruction
This patch adds an extra spdk_thread_send_msg() call to destroy a qpair
to make sure that it isn't freed from the context of a socket write
callback.  Otherwise, spdk_sock_close() won't abort pending requests,
causing their completions to be exected after the qpair is freed.

Fixes #2471

494eb6e58b bdev: Fix race among bdev_reset(), bdev_close(), and bdev_unregister()
There is a race condition when a bdev is unregistered while reset is
submitted from the upper layer very frequently.

spdk_io_device_unregister() may fail because it is called while
spdk_for_each_channel() is processed.

    spdk_io_device_unregister io_device bdev_Nvme0n1 (0x7f4be8053aa1)
    has 1 for_each calls outstanding

To avoid this failure, defer calling spdk_io_device_unregister() until
reset completes if reset is in progress when unregistration is ready
to do, and then reset completion calls spdk_io_device_unregister()
later.

A bdev cannot be opened if it is already deleting. So we do not need
to hold mutex.
