3c4a68cafc nvme: Do not create IO qpair during ctrlr initialization
If nvme ctrlr is resetting or initializing, free_io_qids
bitmap is already freed or not created yet. In that case
an attempt to create IO qpair leads to segmentation fault.

eb09178a59 nvme/rdma: Correct qpair disconnect process
In current implementation RDMA qpair is destroyed right after
disconnect. That is not graceful qpair shutdown process since
there can be requests submitted to HW and we may receive
completions for already destroyed/freed qpair.

To avoid this, only disconnect qpair in ctrlr_disconnect_qpair
transport callback, all other resources will be released in
ctrlr_delete_io_qpair cb.

This patch is useful when nvme poll groups are used since in
that case we use shared CQ, if the disconnected qpair has WRs
submitted to HW then qpair's destruction will be deferred to
poll group.

When nvme poll groups are not used, this patch doesn't change
anything, in that case destruction flow is still ungraceful.
However since CQ is destroyed immediately after qpair,
we shouldn't receive any requests which point to released
resources. A correct solution for non-poll group case
requires async diconnect API which may lead to significant
rework.

There is a bug when Soft Roce is used - we may receive
a completion with "normal" status when qpair is already
disconnected and all nvme requests are aborted. Added
a workaround for it.

843c387a1f nvme: add spdk_nvme_ctrlr_get_discovery_log_page API
This API is a helper for getting the full discovery
log page from a discovery controller.  It will read the
log page header to get the total number of entries,
allocate a buffer for all of the entries, and then
issue a series of get_log_page commands to read each
4KiB worth of entries.

b33e68a789 nvme: call probe_cb when directly connecting to discovery ctrlr
The host may have specified a hostnqn to use to connect to
a discovery ctrlr, so we can't just use the default ctrlr
opts to connect - we need to call the probe_cb (if there is
one) to get any options that the host may have specified.

Tested by using discovery_aer tool, creating a subsystem and
listener, and then adding a host on the target side that matches
the hostnqn specified to the discovery_aer tool.

97277e1459 nvme: use transport internal queue state when deleting unfinished IO queue pair
The NVMe bdev module enables asynchronous IO QP creation by default, after
calling `spdk_nvme_ctrlr_alloc_io_qpair` and `spdk_nvme_ctrlr_connect_io_qpair`,
the queue pair is in connecting state at the beginning, then users may call
`spdk_nvme_ctrlr_free_io_qpair` immediately, and the common layer will
change queue state to NVME_QPAIR_DISCONNECTING and NVME_QPAIR_DESTROYING,
so in function `nvme_pcie_ctrlr_delete_io_qpair` the workaround to wait
for create cq/sq callbacks will not be called, instead of using the common
layer queue state here, we should use the internal `pcie_state`.

Fix #2245.

7a0a2800e0 nvme: Add three APIs for disconnect, start re-enable, and poll re-enable ctrlr
The NVMe bdev module will support two features, delayed reconnect and
delete after multiple failures of reconnect to improve error recovery.

The recently added two APIs, spdk_nvme_ctrlr_reset_async() and
spdk_nvme_ctrlr_reset_poll_async(), were not good enough.

spdk_nvme_ctrlr_reset_ctx was not necessary. It had only a pointer to ctrlr.
Using a pointer to ctrlr directly saves us from undesirable malloc error
processing.

Separate spdk_nvme_ctrlr_reset_async() into spdk_nvme_ctrlr_disconnect()
and spdk_nvme_ctrlr_reconnect_async(). spdk_nvme_ctrlr_disconnect()
disconnects ctrlr including disconnecting adminq.
spdk_nvme_ctrlr_reconnect_async() moves the ctrlr state to INIT.

Then rename spdk_nvme_ctrlr_reset_poll_async() by
spdk_nvme_ctrlr_reconnect_poll_async().

Finally deprecate spdk_nvme_ctrlr_reset_async() and
spdk_nvme_ctrlr_reset_poll_async().

The following patches will change the NVMe bdev module to use these new APIs.

1c083e6200 nvme: set keep alive for discovery controllers
Discovery services using the SPDK nvme driver may
use long-lasting connections that detect AER completions
to determine when there are changes in the discovery
log. This means that we still need to send keep alives
on discovery controller admin queues. So move the
SET_KEEP_ALIVE_TIMEOUT state immediately after
IDENTIFY, and run the SET_KEEP_ALIVE_TIMEOUT state
even for discovery controllers.

Note, we need the IDENTIFY's KAS value to properly
set the keep alive timeout, so we have to keep the
IDENTIFY state before SET_KEEP_ALIVE_TIMEOUT.

a1014fccee nvme_cuse: Fix write-after-free when cuse thread early-exits
There is a bad memory corruption where the code for CUSE attempts to write
one byte (with value 0x1) after the memory is freed.

Context:
When the CUSE device is unregistered, the poller thread is signaled with
fuse_session_exit(), which writes the value 1 to fuse_session::exited.
The poller thread then detects with fuse_session_exited() that it must exit
the routing and finally destroys its own fuse session with
cuse_lowlevel_teardown() before it exits.

However, FUSE may also call fuse_session_exit() for its internal purposes.
I'm not sure exactly under what conditions that happens, but I added
some trace messages and I could clearly see that the CUSE thread exits
before it was requested to exit in cuse_nvme_ns_stop().

If the poller thread early-exits, it would destroy its own FUSE session
(and free the memory) before fuse_session_exit() gets executed, causing
the memory to be corrupted with a single byte of value 0x1.

Reproducer:
The bug can be reproduced by resetting the FUSE session to NULL after it
is destroyed. This will cuse_nvme_ns_stop() to crash with a segmentation
fault in fuse_session_exit() because it tries to access a NULL pointer.

static void *
cuse_thread(void *arg)
{
    [...]
    free(buf.mem);
    fuse_session_reset(cuse_device->session);
+    cuse_device->session = NULL;
    pthread_exit(NULL);
}

This fix:
The fix I suggest is to destroy the FUSE session with
cuse_lowlevel_teardown() after the thread is joined.

state is changed to NVME_QPAIR_DESTROYING and
transport's ctrlr_delete_io_qpair callback is

nvme_transport_ctrlr_disconnect_qpair in
the callback and since qpair's state is
not DISCONNECTED or DISCONNECTING, qpair
is disconnected for the second time.

If spdk_nvme_ctrlr_free_io_qpair is called
when qpair is in ENABLED state than nothing
changes, qpair will be disconnected before destroy.
PCIE/vfio_user don't implement transport disconnect
callback, so they are not affected.

0af4a7cd84 nvme: abort outstanding requests case by case
For DSM command, the NVMe drive may take a long time to finish it,
if we set a small timeout value for DSM command, the bdev/nvme module
will try to reset the IO queue pair when timeout happens,
in `spdk_nvme_ctrlr_free_io_qpair`, we will abort the outstanding
IO requests first, then in the `nvme_pcie_ctrlr_delete_io_qpair`,
we will poll the CQ for any requests that have been completed by
the NVMe controller, if there are NVMe completions in the CQ,
we will finish them again, thus double completions happened.

Here we rename `nvme_qpair_abort_reqs` to `nvme_qpair_abort_all_queued_reqs`,
so the common layer will just abort queued request, and let each
transport to abort outstanding requests case by case.

Fix #2233.

c57bf80497 nvme: Do not construct the namespace object on ns_create
Wait until the namespace is attached, where it does this operation
again. As of this commit it doesn't really matter because it is just
filling in some values in a structure and if it does it twice it's not a
problem. But later when we only allocate active namespaces, we do not
want to allocate the namespace twice.

e40bd53175 nvme/pcie: only set qpair state from qpair's thread
The qpair's state member is only 3 bits of a uint8_t,
and the in_completion_context bit is another bit in that
same uint8_t.

We know that the qpair's state is only ever updated by
one thread, but it is possible that the state could
be modified by one thread, while another thread
is modifying in_completion_context.

in_completion_context is only modified by the thread
that is polling the qpair (or the qpair's poll group).
But with async mode, another thread that has a qpair
on the same PCIe controller could poll its adminq and
reap the SQ completion for the qpair that's owned by
the other thread.

So do *not* set the generic qpair state to CONNECTED
from the SQ completion callback.  Instead just set
the pcie_state to READY, and let the thread that owns
the qpair detect the qpair is READY and set the state
to CONNECTED itself.

Fixes issue #2157.

34c901e308 nvme/tcp: Fix tcp_req->datao calculation issue.
When data digest is enabled for a nvme tcp qpair, we can use accel_fw
to calculate the data crc32c. Then if there are multiple
c2h pdus are coming, we can use both CPU resource directly
and accel_fw framework to caculate the checksum. Then the datao value compare
will not match since we will not update "datao" in the pdu coming order.

For example, if we receive 4 pdus, named as A, B, C, D.
   offset   data_len (in bytes)
A:  0       8192
B:  8192    4096
C:  12288   8192
D:  20480   4096

For receving the pdu, we hope that we can continue exeution even if
we use the offloading engine in accel_fw. Then in this situation,
if Pdu(C) is offloaded by accel_fw. Then our logic will continue receving
PDU(D). And according to the logic in our code, this time we leverage CPU
to calculate crc32c (Because we only have one active pdu to receive data).
Then we find the expected data offset is still 12288. Because "datao" in tcp_req will
only be updated after calling nvme_tcp_c2h_data_payload_handle function. So
while we enter nvme_tcp_c2h_data_hdr_handle function, we will find the
expected datao value is not as expected compared with the data offset value
contained in Pdu(D).

So the solution is that we create a new variable "expected_datao"
in tcp_req to do the comparation because we want to comply with the tp8000 spec
and do the offset check.

We still need use "datao" to count whether we receive the whole data or not.
So we cannot reuse "datao" variable in an early way. Otherwise, we will
release tcp_req structure early and cause another bug.

PS: This bug was not found early because previously the sw path in accel_fw
directly calculated the crc32c and called the user callback. Now we use a list and the
poller to handle,  then it triggers this issue. Definitely, it will be much easier to
trigger this issue if we use real hardware engine.

Fixes #2098

including establishing keep-alive, so there's no point in sending it
during that time.  Additionally, it can stall the initialization if it
gets queued when adminq is connecting.

and it is possible to receive a completion with error (e.g.

rework in rdma transport and will be implemented
later

00277bc5d5 nvme/rdma: Fix searching for qpair by qp_num
Poll group holds lists of qpairs in different states and
when we got rdma completion with error, we iterate these
lists to find a qpair which qp_num matches. qp_num
is stored inside of ibv_qp which belongs to spdk_rdma_qp
structure. When nvme_rdma_qpair is disconnected, pointer
to spdk_rdma_qp is cleaned but qpair may still exist in
poll group list and when we start searhing for qpair by
qp_num we may dereference NULL pointer.

This patch adds a check that pointer to spdk_rdma_qp
is valid before dereferencing it. To minimize boilerplate code,
wrap all check in macro. Add unit test to verify this fix.

971f07b9fb nvme: add tracing to pcie request path
John Kariuki tested this patch on a system with
several Intel P5800X Optane SSDs, to determine the
performance impact of adding these two
spdk_trace_records() in the main NVMe I/O path.

The pathological case (512B random reads on a single
Xeon core) decreased from 13.10M to 12.88M, or 1.7%.
Normal workloads (4KB+) would incur a smaller penalty
since the I/O rate would be much lower - maybe even
unnoticeable..

This is a really valuable tracepoint to have enabled
by default, so I think this small amount of degradation
is acceptable.

3cb9bc2593 nvme: add spdk_nvme_ctrlr_prepare_for_reset()
This new API signals that the ctrlr will soon be
reset. This allows the transport to skip unnecessary
steps in following calls to the driver prior to the
reset - for example, skipping PCIe DELETE_SQ/CQ
commands when freeing an IO qpair.

Note that if we are deleting a qpair after
prepare_for_reset was called, and the qpair is
still waiting for a CREATE_IO_CQ or CREATE_IO_SQ,
we cannot poll for those commands to complete,
but we also cannot free the qpair immediately.
So set a flag for this case to defer the
destruction until the outstanding CREATE_IO_CQ or
CREATE_IO_SQ callback is invoked (typically as an
aborted command when the reset happens).

15b7d3bacc nvme/pcie: defer bad vtophys to completion context
The pcie layer can't always detect bad addresses
in the request at submission time - for example,
the transport may not have any trackers available
and the request gets queued at the generic
nvme level.

So this means that we might detect vtophys failures
during submission time, or in a process_completions
context - the latter happening when we complete
one request which triggers submitting a new request.

Currently if the vtophys failure happens during
submission context, we return -EFAULT to the
caller *and* call the completion callback.  Nowhere
else in the driver do we do both - the intention
has always been that you get one or the other.

So make all of this consistent by tagging the
tracker and the qpair with a flag if we hit a vtophys
error in the submission path.  Return 0 to the caller,
who will then later get a completion callback for the
bad request when the qpair is next processed for
completions.

I considered a separate TAILQ to hold these 'bad'
trackers, but that would have required duplicating
quite a bit of the tracker completion code for this
one case.  The flag on the pqpair is already in the
hot cacheline, so it's cheap to check it.  We will
only interate the outstanding_tr list when that flag
is set, so this should have zero impact to performance.

Fixes issue #2085.

ea0aaf5e85 nvme: Transports now set qpair state to NVME_QPAIR_CONNECTED inside
.ctrlr_connect_qpair

Previously this was assumed to be a synchronous process so the generic
layer transport code updated the state after .ctrlr_connect_qpair
returned. In preparation for making this support asynchronous mode,
shift that responsibility down into the individual transports.

While none of the transports actually do this asynchronously, insert a
busy wait in nvme_transport_ctrlr_connect_qpair to wait for the qpair to
exit from the CONNECTING state. None of the upper layer code can
actually correct handle a transport doing this asynchronously, so the
busy wait will cover that.

We find a few files to get the size of a member of a struct. How to
do it is a little complex. So add a macro to do it will be helpful
to read the current code and develop new features.

lib/dif had used member_size() internally but Linux use sizeof_member()
as the macro. Besides, SPDK have used upper case letters for similar
macros, SPDK_CONTAINEROF() and SPDK_COUNTOF(). Hence spdk_member_size()
may be good but propose SPDK_SIZEOF_MEMBER() as the macro.

This fix is as same as for NVMe bdev module.

If a ANA log page has two or more ANA group descriptors, the second

Then runtime error would occur as follows:

runtime error: member access within misaligned address 0x612000000074
for type 'const struct spdk_nvme_ana_group_descriptor', which requires
8 byte alignment

nvmf_get_ana_log_page() in lib/nvmf/ctrlr.c creates a ANA log page
data and processes 8 bytes alignment correctly because we got the
same runtime error before. However, lib/nvme had been missed at that
time.

ca0339d8e5 nvme_cuse: Return ENOTTY in case unsupported ioctl is sent to a device
Latest nvme-cli (>= 1.13) fails to issue commands towards SPDK's cuse
ctrl device, e.g.:

$ nvme get-feature /dev/spdk/nvme0 -f 1 -s 1 -l 100
nvme_cuse.c: 654:cuse_ctrlr_ioctl: *ERROR*: Unsupported IOCTL 0x4E40.
get-namespace-id: Invalid argument

The reason is because nvme-cli now also sends NVME_IOCTL_ID to the
target device to determine if it's indeed a controller or a ns. In
case kernel returns ENOTTY then nvme-cli considers the device to be
a controller. Since cuse_ctrlr_ioctl() returns EINVAL in such a case
the nvme-cli fails.

To avoid this simply replace EINVAL with ENOTTY for the ioctls that
may be not supported by ctrl or ns device.

nvme-cli commit in question:

4246e79c04 nvme: change nvme_transport_ctrlr_delete_io_qpair to void
Returning an error from this function is not useful - there
is nothing the caller can do with that information. So
change the return value to void.  Also add ERRLOG and assert
if a transport actually returns a non-zero status, to
force the transport implementer (which must be an out-of-tree
transport) to make changes as necessary.

c081a84cd2 nvme: always return success from delete_io_qpair
It is not uncommon for delete_io_qpair to fail, for
example when a controller is hot removed.  So even
if SQ or CQ deletion fails, continue with freeing
resources and report success back up the stack.
There is really nothing the application can do to
account for this failing anyways.

Upcoming patches will add additional checks to
ensure failing delete_io_qpair status never gets
propagated to the caller.

a82e8478ea lib/nvme: Do not retry aborts if ctrlr is failed.
Fixes #2022

If queued aborts are present when trying to fail a ctrlr
using spdk_nvme_ctrlr_fail(), then the abort command completion
will attempt to retry one of the queued aborts.
This eventually leads to a segfault that can be avoided by not
retrying any queued aborts.

05c7a2cc0f nvme/fabrics: Fix trid trstring populate
After correct trstring initialization, it is
overwritten with trstring value of the current
probe ctx. That leads to a problem when initiator
connects to a sbusystem with listeners of different
transport types (e.g. TCP and RDMA). If probe_ctx has
TCP type, than discovery probe initialized probe trid
with trtype=RDMA and trstring=TCP. As results, SPDK
creates TCP controller with trtype=RDMA and we hit
assert in nvme_tcp_qpair function.

3959e397d4 nvme: Add new detach to a detach context while it is being polled
This update will allow us to use spdk_nvme_detach_async() and
spdk_nvme_detach_poll_async() easier to aggregate multiple detachments.

Previously, we could do:
    spdk_nvme_detach_async()
    spdk_nvme_detach_async()
    spdk_nvme_detach_async()
and then started doing spdk_nvme_detach_poll_async().

Hence aggregating multiple detachments is already supported.

After this patch, the following sequence is possible:
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_poll_async() = -EAGAIN
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_async() = 0
    spdk_nvme_detach_poll_async() = -EAGAIN
    spdk_nvme_detach_poll_async() = -EAGAIN
    spdk_nvme_detach_poll_async() = -EAGAIN
    spdk_nvme_detach_poll_async() = 0

The actual changes is to remove the variable polling_started from
struct spdk_nvme_detach_ctx because it is not necessary anymore.

Clarify this change via updating the header file and CHANGELOG.
Verify this change by unit test.

c4fafdb215 env: only pass failing address to spdk_pci_error_handler
siginfo_t is a GNU extension.  SPDK (and DPDK) have
direct dependencies on GNU extensions, but it's a bit
nicer if external modules don't also need to define
_GNU_SOURCE.  Currently siginfo_t parameter in the
spdk_pci_error_handler is the only thing that violates
this.

Note that DPDK also supports registering sigbus handlers,
but they take the failing address as a parameter instead
of the full siginfo_t structure.  Let's adopt the same
for SPDK.

While here, remove an extra semicolon that was just after
the virtio sigbus handler function signature that was
updated in this patch.

130c94c489 nvme: add quirks for new RedHat QEMU NVMe dev/vendor ID
QEMU 6.0 by default uses a RedHat dev/vendor ID rather
than the Intel one that has always been used to date.
We need the NVME_QUIRK_MAXIMUM_PCI_ACCESS_WIDTH quirk
so that we do not use wide instructions to copy SQEs
to a virtualized CMB, since QEMU does not support
that.

The NVME_INTEL_QUIRK_NO_LOG_PAGES quirk is only needed
for devices with SPDK_PCI_VID_INTEL, so we do not need
to carry this one over to the new REDHAT entry.

Each time the following file
"/sys/kernel/config/nvmet/subsystems/nqn_name/namespaces/ns_id/enable"
on the target side was changed, the SPDK initiator should receive an
async event (type: SPDK_NVME_ASYNC_EVENT_TYPE_NOTICE, info:
SPDK_NVME_ASYNC_EVENT_NS_ATTR_CHANGED).
But actually not.
Since for SPDK, when target sent the non-first event, the condition
"nvmet_aen_bit_disabled(ctrl, NVME_AEN_BIT_NS_ATTR)" that prevents
target from sending event was matched.
This commit fix this issue by issuing a get_log_page cmd for each async
event received, just as the kernel initiator does.

Fixes #1825.

9f5e3c99f2 nvme: add spdk_nvme_ctrlr_is_fabrics()
We map the SPDK_NVME_TRANSPORT_* values directly to
the NVMe-oF trtype values.  Since PCIe isn't
Fabrics, we choose 256 which is outside of the
8-bit trtype range of values.

So we can just check if trtype >= 256 to determine
if the trid is for fabrics or not.  This is
preferable to checking PCIE || VFIOUSER in case
additional non-fabrics transport types are added
in the future.

I considered taking a trid as the parameter instead,
but went this route since it is consistent with
the existing spdk_nvme_ctrlr_is_discovery().

d6f6ffd274 nvme: add NVME_CTRLR_STATE_CONNECT_ADMINQ
Connect the adminq as part of controller initialization
instead of controller construction.

We never actually 'connected' the adminq for
PCIe or vfio-user transports, since its a nop.
But their connect_qpair transport ops function
is also a nop for the adminq, so it's fine to
generically connect the adminq across all transports.

Note that we cannot read registers (cc or csts)
during controller initialization now until after
the adminq has been connected since reading fabrics
registers depends on a connected adminq.  This gets
special cased for now, but eventually reading
cc and csts will need to be part of the state machine
itself to make it asynchronous.

5354d0c63f nvme: reset mapping_length correctly for contig SGL
spdk_vtophys() takes a mapping_length parameter, so
it can return the length for which the returned
virtual address is valid.

But spdk_vtophys() will only return the max
between the valid length and the input mapping_length
parameter.

So the nvme SGL building code for contiguous buffers
was broken, since it would only set the mapping_length
once, before the loop started.  Worst case, if a buffer
started just before (maybe 256 bytes) before a huge page
boundary, each time through the loop we would create
a new SGL for only 256 bytes at a time, very quickly
running out of SGL entries for a large buffer.

Fixes #1852.

6fd1cc3716 nvme: remove IDENTIFY_CNS quirk from normal QEMU SSDs
The IDENTIFY_CNS quirk was applied as part of QEMU
OCSSD handling in commit 6442451b.  But it was applied
not only to the OCSSD dev ID, but also the dev ID
for non-OCSSD NVMe controllers.

Starting with QEMU 5.2, QEMU will allocate a default
256 namespaces, but only some are active (associated
with the backing disks specified by the user).  QEMU
supports IDENTIFY_CNS, but since this quirk was set,
we wouldn't send a real IDENTIFY_CNS and instead
would just populate a fake list where all namespaces
were considered active.  This causes breakage in
a few places - mainly where we iterate through
the active namespaces, and then are surprised that
calling spdk_nvme_ns_is_active() returns false.

It was also breaking bdev_nvme_attach_controller RPC,
since by default we can only support returning 128
names, but since all of the namespaces were deemed
active, it was trying to return 256.

Fixes #1916.

c7bb68aa3e nvme: Handle errors returned by submit function
When a request is submitted, it may have incorrect iov
alignment that doesn't fit PRP requirements. In the
current version an internal function fails such a request
and returns a NULL pointer. This is mapped to -ENOMEM
error which is returned to generic bdev layer where
such a request is queued in a "nomem_io" queue and
later can be resubmitted. That is incorrect and such
a request must be completed immediately. To fail the
request, we need to differentiate between -ENOMEM and
other cases, so we pass a pointer to a result to
local nvme functions

04cd292237 nvme/quirk: add MDTS excludes interleaved metadata quirk
The specification for Maximum Data Transfer Size (MDTS) says this field
should include the length of metadata, if metadata is interleaved with the
logical block data.  However, some drives can support MDTS without counting
the interleaved metadata, so for this case SPDK will only use data length
without interleaved metadata length.

38736d993d nvme: zero shadow doorbell registers when freeing qpair
The shadow registers need to be zero when the qpair is
created.  This happens automatically when a given qid
is used for the first time, since the page is allocated
with zmalloc. But if a qid is reused, we need to make
sure its shadow registers are cleared *before* we create
the qpair again with the same qid.

So clear the registers in nvme_pcie_ctrlr_delete_io_qpair,
just after the cq is deleted.

Fixes issue #1795.

2910ba6c53 nvme: simplify controller statemachine
For the following nvme controller statemachine states:
NVME_CTRLR_STATE_IDENTIFY_NS
NVME_CTRLR_STATE_IDENTIFY_ID_DESCS
NVME_CTRLR_STATE_IDENTIFY_NS_IOCS_SPECIFIC

The statemachine can either:
- Jump to succeeding state
- If active ns list is empty, jump directly to NVME_CTRLR_STATE_CONFIGURE_AER
- In the unlikely case if NVMe completion error, jump to NVME_CTRLR_STATE_ERROR

Simply this such that we either:
- Jump to succeeding state
- In the unlikely case if NVMe completion error, jump to NVME_CTRLR_STATE_ERROR

This will help to reduce the complexity of the nvme controller statemachine,
especially considering that there are new additional states
(NVME_CTRLR_STATE_IDENTIFY_NS_DIRECTIVE and
NVME_CTRLR_STATE_CONFIGURE_NS_STREAMS) currently on review that would continue
with the bad habit of having three possible jump states instead of just two.

1f49ee235f nvme: only reassign start_valid if we fetched a new SGE
For a SGL using PRPs, there is always an alignment check of the start
address in the beginning of the loop. This is stored in start_valid.

If the start is indeed valid, we might fetch a new SGE,
and then perform a second alignment check on this new SGE.

However, this second alignment check is done unconditionally,
meaning that for the last SGE in a request, we check if the
same start address is aligned twice.

Only perform the second alignment check if we actually fetched
a new SGE.

014baeb8ef nvme: add support for ZNS zone append vector variant
We already have support for spdk_nvme_zns_zone_append(),
add support for spdk_nvme_zns_zone_appendv() (zone append with
NVME_PAYLOAD_TYPE_SGL).

_nvme_ns_cmd_rw() currently performs verification of the SGL,
if the parameter check_sgl is set. This parameter is set for all
calls with payload of type NVME_PAYLOAD_TYPE_SGL.

In order to be able to perform the same check_sgl verfication on
zone append vectors, we need to refactor _nvme_ns_cmd_rw() a bit.

Setting check_sgl ensures that _nvme_ns_cmd_split_request_sgl() or
_nvme_ns_cmd_split_request_prp() gets called.

These functions will split an oversized I/O into several different
requests. However, they also iterate the SGE entries, verifies that
the total payload size, total SGE entries is not too many, and that
buffers are properly aligned. A proper request will not get split.

For zone append, splitting a request into several is not allowed,
however, we still want the verification part to be done, such that
(e.g.) a non first/last SGE which is not page aligned, will cause
the whole request to be rejected.
(In the case of spdk_nvme_ns_cmd_write(), a non first/last SGE which
is not page aligned will instead cause the request to be split.)

An alternative would be to try to rip out the verification part from
_nvme_ns_cmd_split_request_sgl() and _nvme_ns_cmd_split_request_prp().
However, that is non-trivial, and would most likely end up with a lot
of duplicated code, which would easily get out of sync.

4249dc1010 nvme: account for PRACT when calculating max sectors per transfer
There is a special case when using 8-byte metadata + PI + PRACT
where no metadata is transferred to/from controller.

Since _nvme_ns_cmd_rw() already calculates the proper sector size
using _nvme_get_host_buffer_sector_size(), which takes PRACT into
account, change the sectors_per_max_io calculation to also take
PRACT into account.

This will avoid certain requests that don't need splitting getting
split.

b05b3d0a12 nvme: add assert in nvme_ns_cmd_zone_append_with_md()
Zone append commands cannot be split.
_nvme_ns_cmd_rw() should never cause a NVME_PAYLOAD_TYPE_CONTIG
zone append request to be split.

This is currently true, but add an assert to make sure that
any refactoring to _nvme_ns_cmd_rw() does not break this promise.
Also add error handling, since release builds are built with
asserts disabled.

Follow-up patches will refactor _nvme_ns_cmd_rw().

e329ec45a6 nvme: add set_nvme_pcie_set_hotplug_filter
This function allows applications to specify whether
they wish to allow probing a newly attached NVMe
PCIe SSD.

The env layer will only even probe devices that have
been allowed.  By default, this is all devices, but
if the user has specified some list of
allowed PCI addresses (via spdk_env_opts pci_allowed)
then newly attached PCIe devices are implicitly not
allowed.  This API allows applications to add
device addresses to the allowed list after the
application has started.

This API will be useful for use cases where multiple
SPDK processes are running on one server, and assignment
of PCIe SSDs to those processes are based on some function
of the SSD's PCIe address.

Fixes #1777.

When a qpair cannot be allocated because the transport connection fails,
the qpair was freed without unlinking it from the other structures.
This was leading to a segfault when attempting to create and free other
qpairs.
Also added a unit test to cover this case.

aa6767fb14 nvme: add support for ZNS zone append command
The Zone Append command is an optional command in the Zoned Namespace
Command Set.

Zone Append differs from a regular write, in that the command is not
given an exact LBA of where to write the data.

Instead the user has to set the zslba field to the start of a zone,
and the data will be appended to that zone.

The actual LBA where the data was stored is returned in the
spdk_nvme_cpl, where Dword0 contains 31:00 of the ALBA field,
and Dword1 contains bits 63:32 of the ALBA field.

_nvme_ns_cmd_rw() simply cannot "check SGL" if the payload
is not a SGL. Doing so regardless just makes the code harder
to read.

We still send in check_sgl == true, when we are calling
_nvme_ns_cmd_rw() with a payload of type NVME_PAYLOAD_SGL.

Here is the three examples that can work with target:

identify -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g
perf -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g -q 1 -o 4096 -w read -t 10
reconnect -r 'trtype:VFIOUSER traddr:/var/run/muser/domain/muser0/8' -g -q 32 -o 4096 -w randrw \
-M 50 -t 10 -c 0xE

You can run the following test script test/nvmf/target/nvmf_vfio_user.sh to have a quick test,
currently enabled with NVMe Identify,Perf,Reconnect tools.
