a8326f8155 nvmf/vfio-user: avoid doorbell reads in cq_is_full()
Profiling data showed the deference of the CQ head in cq_is_full() was a
significant contributor to the CPU cost of post_completion(). Use the
cached ->last_head value instead of a doorbell read every time.

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.

Fixes #2481.

For this issue, the target was completing a
previously submitted AER, not the fuzzed fused
command.  The initiator would then submit another
AER to replace the completed one, but the target
complained that the initiator sent too many AERs
since the target didn't really know it had completed
an AER so hadn't adjusted its num_aer count.

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

3b047a6162 nvmf/vfio-user: support shadow doorbells
As per the NVMe specification, a host can identify two areas of guest
memory: one of which is used for the host-written doorbells, and one of
which contains event indexes. The host writes to the shadow doorbell
area, but also writes to the controller's BAR0 doorbell area if the
corresponding event index is crossed by the update. This avoids many
mmio exits in interrupt mode, where BAR0 doorbells are not directly
mapped into the guest VM, with greatly improved performance.

This isn't a useful feature in BAR0 doorbells are mapped into the VM, so
we explicitly disable support in that case.

NB: the Windows NVMe driver doesn't yet support this feature.

Although the specification says that the admin queues should also engage
in this behaviour, in practice, no VM does, so have to include some
hacks to account for this.

72925e3db8 nvmf/tcp: delay completion for zcopy reqs w/ in-progress writes
When a qpair is disconnected, any outstanding zero-copy requests are
freed to release their buffers before the qpair gets destroyed.
However, if there is a PDU being sent to the host as part of this
request (e.g. C2HData/R2T), we need to wait until that write is done
before freeing the request to avoid freeing it twice.

183c348557 nvmf/rdma: issue fused cmds consecutively to tgt layer
RDMA READs can cause cmds to be submitted to the target
layer in a different order than they were received
from the host.  Normally this is fine, but not for
fused commands.

So track fused commands as they reach
nvmf_rdma_request_process().  If we find a pair of
sequential commands that don't have valid FUSED settings
(i.e. NONE/SECOND, FIRST/NONE, FIRST/FIRST), we mark
the requests as "fused_failed" and will later fail them
just before they would be normally sent to the target
layer.

When we do find a pair of valid fused commands (FIRST
followed by SECOND), we will wait until both are
READY_TO_EXECUTE, and then submit them to the target
layer consecutively.

This fixes issue #2428 for RDMA transport.

The process of matching qpair to poll group is split into
two distinct parts that occur on different threads.
See spdk_nvmf_tgt_new_qpair().

This results in a race condition for TCP between spdk_sock_map_lookup()
and spdk_sock_map_insert(), which are called in spdk_nvmf_get_optimal_poll_group()
and spdk_nvmf_poll_group_add() respectively.

Fixes #2113

This patch picks a hint from nvmf_tcp for next poll group,
which is then passed down to spdk_sock_map_lookup().

When matching placement_id exists, but does not have
a poll group assigned - the hint will be used.
