b70b16acba nvmf: don't use request internal variable after req_complete callback
vfio-user transport `req_complete` callback will zero the internal
NVMe command and response fields, the common NVMf library should
not use them after the callback, so here we use stack variables
to save them before the `req_complete` callback.

Fix issue #1965.

d07c581b7d nvmf: nvmf_get_ana_log_page should use iov to store the log page
nvmf_get_ana_log_page used req->data to store the log page result.
While the req->data only contains the first iov, if req->iovcnt is
larger than 1, the req->data may not hold the complete log page; and
even worse, the log page result may be written to invalid address and
cause memory corruption.

019a5361a5 nvmf/rdma: Use contig buffers for multi SGL payload
Currently we allocate buffers perf each SGL descriptor.
That can lead to a problem when we use NVME bdev with
PRP controller and length of the 1st SGL descriptor is
not multiple of block size, i.e. the initiator may send
PRP1 (which is SGL[0]) which end address is page aligned
while start address is not aligned. This is allowed by
the spec. But when we read such a data to a local buffer,
start of the buffer is page aligned when its end is not.
That violates PRP requirements and we can't handle such
request. However if we use contig buffer to write both
PRP1 and PRP2 (SGL[0] and SGL[1]) then we won't meet
this problem.

Some existing unit tests were updated, 1 new was added.

Fixes github issue #1853

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

fa79643725 nvmf: remove struct spdk_bdev definition dependencies
1) use spdk_bdev_get_name() accessor
2) use __SPDK_BDEV_MODULE_ONLY #define

The latter allows nvmf to just get the spdk_bdev_module
definitions and APIs that it needs for claiming bdevs
for purposes of avoiding the same namespace used in
different subsystems.

This also ensures that future changes to structures
like spdk_bdev and spdk_bdev_io will not cause
lib/nvmf so version changes.

Note: we include bdev_module.h explicitly in the
nvmf/subsystem unit tests now, before including
subsystem.c, because the unit tests do depend on
knowing the internal structure of spdk_bdev.

b32cfc467b nvmf: Support physical block size if exposed by bdev
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

and for command using PRP, there maybe multiple pages, when
parsing the PRP list to local IOVs, we need a parameter to check
that the maximum number of vectors can't exceed the IOVs, this API
can't meet the requirement, while here, we add a new API `spdk_nvme_map_cmd`
and with a new parameter `max_iovcnt` to fix this case, and it can
also cover the command using SGL in the coming patches.

Previously we poll the MMIO callbacks in the context of ADMIN queue's
poll group, here we do some improvement to start a poller to do MMIO
poll, then the group poll will only process NVMe commands while the
MMIO poller will process MMIO access.

This is useful when doing live migration, because the migration region
defined by VFIO is a BAR region, we should stop polling queue pairs
but ack the MMIO accesses during the live migration.

ba6f6c5eb0 nvmf: wait for qpair disconnect cbs when removing subsys
nvmf_poll_group_remove_subsystem_msg() disconnects all
qpairs associated with controllers in the specified
subsystem.  If it finds any controllers that need to
be disconnected, it sends a message to the running
thread to execute the same function again later.

But when it runs again later, the qpair may no longer
be in the poll group, but there could still be
outstanding messages being sent between threads.  For
example, _nvmf_qpair_destroy() needs to send a message
to the ctrlr->thread to clear the qpair mask bit.

All of this could result in the nvmf target starting
to destroy poll groups prematurely.  Destroy poll
groups results in the nvmf spdk_threads exiting. If
there are still messages being processed from
the STOP_SUBSYSTEMS target state, we can get
use-after-free errors since processing of those
messages could access freed memory associated with
the exited thread.

Fixes issue #1850.
