695425c776 nvme: move spdk_nvme_map_cmd to nvmf/vfio-user
Nvmf/vfio-user uses this API to map NVMe command sent from
VM from Guest Physical Address to Host Virtual Address, so
now we moved this API from the nvme library to nvmf/vfio-user
as an internal API.

UT code will be added back in coming patch.

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.

Fixes issue #1986.

4f4f505c77 nvme: get changed ns log once AER notice of ns changed received.
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.

process and it should handle all the devices.

And align nvme to the hotplug lib

Add the ADD uevent support for allowing the
device hotplug.

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

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.

Sometimes it is more optimal to get the zone size in number
of sectors, instead of in number of bytes.

Therefore, add a new spdk_nvme_zns_ns_get_zone_size_sectors()
function to get zone size in number of sectors.

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.

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.

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.

if spdk_nvme_ctrlr_reset() failed, nvme_ctrlr_fail() is called, and
then if spdk_nvme_ctrlr_process_admin_completions() failed,
nvme_ctrlr_fail() is called.

We don't know which one comes first but nvme_ctrlr_fail() should do
nothing if the ctrlr is already failed.

Hence we should avoid setting ctrlr->is_failed and calling
nvme_transport_ctrlr_disconnect_qpair() twice.

However we should set ctrlr->is_removed if the parameter hot_remove is true.

We do these changes in this patch.

3c2190c214 nvme: capture ticks for timeout before checking state
In some extreme use cases, an SPDK process could get
swapped out for a long period of time just after
we checked the state but before we called spdk_get_ticks().
So now we will only timeout if the timer expired before
we checked the state *and* the state did not advance.

It's possible we could just move the timeout check
to before the ctrlr->state switch, but I was
hesitant to change the flow for this case.

Fixes issue #1720.

17afd268df nvme: call correct remove_cb when device is removed
When a device is removed, we should use the remove_cb
that was specified when the device was originally probed
and attached, if one was set.

Also add a new spdk_nvme_ctrlr_set_remove_cb API.  This
can be used for cases where a different remove_ctx is
desired than was specified for the probe call.  This
also enables setting a remove_cb when using connect APIs
which do not have a way currently to provide a remove_cb.

This also requires fixing the bdev nvme module, which
was depending on the previously errant behavior.

Fixes issue #1715.

Where the value being printed is an unsigned 64-bit value, use PRIu64

The ratified NVMe TP 4056 added a CSI field (in cdw14) to the Get Log Page

log page (spdk_nvme_ctrlr_cmd_get_log_page() and
spdk_nvme_ctrlr_cmd_get_log_page_ext()), avoid creating a third one for
now, since nvme_ctrlr_get_zns_cmd_and_effects_log() itself can leverage
one of the existing public functions.

d7345e08ae nvme: group NVME_CTRLR_STATE_WAIT_FOR_* states together
While I assume that the initial thought of having the
NVME_CTRLR_STATE_WAIT_FOR_* state directly after the state which it is
waiting for, was to make it clear for the reader in which order the
states will be executed.
However, it feels silly to have the same code copy pasted everywhere.

Someone who needs to add a new state will still need to edit
nvme_ctrlr_state_string() and enum nvme_ctrlr_state, which still defines
the NVME_CTRLR_STATE_WAIT_FOR_* state directly after the state which it
is waiting for.

In one way, moving the NVME_CTRLR_STATE_WAIT_FOR_* states to the end of
nvme_ctrlr_process_init(), when reading nvme_ctrlr_process_init(), it is
actually easier to see the ordering of the states which actually do
something of significance.

d296fcd8d9 nvme_tcp: Fix icreq/icresp handing with zcopy enabled.
There is a problem with TCP zcopy enabled:
1. TCP initiator sends icreq and start polling a qpair. Polling of qpair
actively calls nvme_tcp_read_pdu function
2. nvme_tcp_read_pdu: qpair is in NVME_TCP_PDU_RECV_STATE_AWAIT_PDU_CH state,
it reads 8 bytes of common PDU header. It determines the type of the PDU
and finds the size of PDU_PSH header.
3. nvme_tcp_read_pdu: qpair is in NVME_TCP_PDU_RECV_STATE_AWAIT_PDU_PSH state.
It should read 120 bytes of icresp PDU. The number of bytes which needs to be
read is pdu->psh_len - pdu->psh_valid_bytes. qpair receives 120 bytes
(the full PDU) and calls nvme_tcp_pdu_psh_handle -> nvme_tcp_icresp_handle.
Here we check that we haven't yet received buffer reclaim notification and
simply return from this function. At the same time we continue to poll the qpair.
4. nvme_tcp_read_pdu: qpair is in NVME_TCP_PDU_RECV_STATE_AWAIT_PDU_PSH state
and tries to read data from a socket again. The number of bytes is
pdu->psh_len - pdu->psh_valid_bytes. But now pdu->psh_len == pdu->psh_valid_bytes,
so we call nvme_tcp_read_data with zero length.
readv with zero length is commonly used to check errors on the socket,
but in our case there is no errors and readv returns 0.
5. nvme_tcp_read_data treats zero as error and return NVME_TCP_CONNECTION_FATAL.

Fix is to handle icresp, but leave qpair in INITIALIZING state until
we receive acknowledgement for icreqsend_ack. We also move qpair to
NVME_TCP_PDU_RECV_STATE_AWAIT_PDU_READY recv_state so recv_pdu
will be zerofied and qpair will try to read a common PDU header.
But since it is not initialized yet, it won't receive anything
from the target.

parameter in_capsule_data_size is applied to all qpair types -
admin and IO. Also we allocate resources when we get a connection
request, so we don't know qpair type at this moment.
Create a list of buffer in TCP poll group to support ICD up
to 8192 bytes when configuration ICD is less than this value.
The number of elements in this pool is hardcoded, it is planned
to add a new configuration parameter later.

Fixes issue #1569

e385cafa72 nvme: Don't log an error when we can't resubmit all requests
In TCP NVME initiator with zero copy enabled requests might be
completed asynchronously - out of qpair_process_completions
context. At the same time we calculate requests completed
asynchronously so that generic NVME layer can resubmit
queued requests after calling qpair_process_requests (or
poll_group_process_requests).
But there is a time gap between async request complete and
qpair_process_completions and the user can submit new IO
thereby decrease the number of free TCP requests. That means
that there might be less free requests than we excpected when
we try to resubmit queued requests.
The solution is change ERRLOG to DEBUG log since it is not a
fatal case.

c72a16431a nvme/tcp: Fix check of completion number during icresp handling
The current approach checks "rc == 0". It worked before adding
polling of poll group since a single qpair should return 1
completion for its own icreq while poll group can return
several completions for all qpairs attached to this poll
group (but .e.g not for those qpair who is waiting for the
completion).

spdk_nvme_detach_ctx holds all nvme_ctrlr_detach_ctx in a sequence

spdk_nvme_detach_ctx has a boolean variable polling_started to prevent

257fcb7352 lib/nvme: Make nvme_ctrlr_shutdown() asynchronous
This patch is the first of the patch series to make spdk_nvme_detach()
asynchronous.

We have lengthy shutdown notification, i.e., we have to wait a long time
until shutdown processing is completed, in some SSDs. If the running system
has many such SSDs, we see large intolerable delay.

SPDK provides a controller option, no_shn_notification as a workaround.
We can use the workaround if the use case of the detach is to switch to
the next application without system reboot. However, we cannot use the
workaround if we want to do system reboot after detach.

To mitigate such lengthy shutdown notification, we need to parallelize
detachment among SSDs.

Hence the patch series will introduce an asynchronous detach API and
will use the API to parallelize detachment.

This patch adds the following changes.

Introduce a context structure and separate nvme_ctrlr_shutdown()
itno nvme_ctrlr_shutdown_async() and nvme_ctrlr_shutdown_poll_async()
using the context structure.

Name the context structure as nvme_ctrlr_detach_ctx because it will be
used only in internal APIs. The upcoming public APIs will support
multiple detachment and will have the contest structure named as
spdk_nvme_detach_ctx.

Use TSC instead of counter because polling interval will be controlled
by the caller.

Use the convenient macro, SPDK_CEIL_DIV(), to round off the time
value in milliseconds.

3be2935701 nvme: move ZNS specific functions to their own header file
Move ZNS specific functions to their own header file:

This is similar to how it's done for e.g. NVMe-oF with

This avoids cluttering the nvme.h header with ZNS specific functions.

A SPDK program that wants to use the spdk_nvme_zns_* functions will
need to include include/spdk/nvme_zns.h, however, this is similar
to how e.g. spdk_nvmf namespaced functions work.
This change is safe to do now, since there is no SPDK release with
ZNS so far.

198a3ad2fd nvme: if no command set is requested, use the most reasonable default
Since namespace types were introduced in NVMe, the CC.CSS register
has a new value (SPDK_NVME_CC_CSS_IOCS) which indicates that all
supported command sets should be selected/enabled. This possibly
includes command sets other than NVM and ADMIN only.

Therefore, if a SPDK application wants enable all the command sets
that the controller supports, it has to explicitly set
opts->command_set to SPDK_NVME_CC_CSS_IOCS.

To avoid possibly a lot of SPDK applications having to set this
parameter, check if the user requested a command set explicitly,
if not, make SPDK automatically use the most reasonable default,
based on the supported bits set by the controller.
The most common case is that you want to enable (all) the command
sets that the controller supports.

A user will still be able to restrict the controller to only use
the NVM command set (or ADMIN only), by setting opts->command_set
to a specific value.

Since the current default command set value specified by
spdk_nvme_ctrlr_get_default_ctrlr_opts() is SPDK_NVME_CC_CSS_NVM,
which is defined as 0, we cannot know if the user specified a
command set explicitly or not.
To solve this, change the default command set value specified by
spdk_nvme_ctrlr_get_default_ctrlr_opts() to CHAR_BIT (0x8), which
is larger than the largest value that can be set in CS.CSS (which
is only 3 bits wide, thus 0x7).

c4d1b7d57a nvme: add new state to get Identify IOCS Specific Namespace data structs
Add a new state in the SPDK NVMe state machine in order to fetch
I/O Command Set Specific Namespace data structures.

Right now there is only support for the Zoned Namespace Command Set
Specific Identify Namespace data structure.

The NVM Command Set Specific Identify Namespace data structure is
all zeroes right now, reserved for future use.
The Key Value Command Set Identify Namespace data structure is not
all zeroes, however, adding support for Key Value is outside the
scope of this patch.

The new NVME_CTRLR_STATE_IDENTIFY_NS_IOCS_SPECIFIC state is added
after the NVME_CTRLR_STATE_IDENTIFY_ID_DESCS state. This is because
we need to have fetched the identifiers in the desc list in order
to know which command set a namespace belongs to.

A slightly nicer design might have been to refactor the NVMe state
machine to first fetch the id desc list, then the identify namespace
struct, and finally the identify IOCS specific namespace struct.
However, since this would have required a lot of changes, it didn't
really seem justified.

64563ada5d nvme: add new state to get Identify IOCS Specific Controller data structs
Add a new state in the SPDK NVMe state machine in order to fetch
I/O Command Set Specific Controller data structures.

Right now there is only support for the Zoned Namespace Command Set
Specific Identify Controller data structure.

The NVM Command Set Specific Identify Controller data structure is
all zeroes right now, reserved for future use.
The Key Value Command Set Identify Controller data structure is also
all zeroes right now, reserved for future use.

The new NVME_CTRLR_STATE_IDENTIFY_IOCS_SPECIFIC state is added
after the NVME_CTRLR_STATE_IDENTIFY state. That way, if support for
the Zoned Namespace Command Set is enabled during probing, we will
fetch the Zoned Namespace Command Set Specific Identify Controller data
structure, regardless if any Zoned Namespaces are attached or not, and
no additional steps will be needed once a Zoned Namespace is attached.

Since we only have one command set to fetch, avoid creating
NVME_CTRLR_STATE_IDENTIFY_IOCS_SPECIFIC substates, although that will
probably be needed when support for another command set is added.

b2570934cb nvme: change the type of spdk_nvme_ctrlr::state from enum to int
When adding an additional state to enum nvme_ctrlr_state, abidiff (1.6.0)
will report that almost every public interface in the nvme library has
been impacted, causing test/make/check_so_deps.sh to fail.

While it is possible that by adding another state, the compiler decides
to use a larger data type for representing enum nvme_ctrlr_state, abidiff
shouldn't complain in the first place, since spdk_nvme_ctrlr is only
ever exposed as an opaque handle. It can never be accessed directly.

Jim Harris suggested to workaround this abidiff bug by changing the type
of spdk_nvme_ctrlr::state from enum to int.

d1db020954 nvme: add a csi parameter to nvme_ctrlr_cmd_identify()
With the introduction of namespace types, the identify command has
gained an additional parameter: Command Set Identifier (CSI).

This parameter is similar to the existing parameters NSID and CNTID,
and is not used by all CNS values.

Most notably, the CSI parameter is not used for the existing CNS
values 00h (ID NS) and 01h (ID CTRL).
There are new CNS values, e.g. 05h (ID IOCS specific NS), and
06h (ID IOCS specific CTRL), which do take the new CSI parameter.

The new CNS values instead return Command Set Specific data structures,
which is basically an additional data structure. Therefore, the CNS
values 00h and 01h are very much still in use.
(Even the NVM Command Set has a Command Set Specific data structure,
even though all fields in that data structure are currently reserved.)

Since the CSI parameter is unused by all the existing calls to
nvme_ctrlr_cmd_identify() (since none of the calls send in a CNS value
that uses CSI), simply send in 0 for all existing calls.
No functional change intended.

726ac67c55 nvme: use the most appropriate is_active() function
There are two different is_active() functions.
spdk_nvme_ctrlr_is_active_ns() which iterates through the active_ns_list,
and spdk_nvme_ns_is_active(), which simply checks the nsdata.
There is an event callback that refreshes active_ns_list when a relevant
events has occured.

In nvme_ns_construct(), nvme_ctrlr_identify_ns() has just been called,
so we know that nsdata is as fresh as possible.

Hence, there is no reason to iterate through a less fresh active_ns_list.
Since we know that the nvme_ctrlr_identify_ns() call was done through the
same controller, we also know that the active/inactive is from the
perspective of the correct controller, so that is not a reason to use the
less efficient is_active() function.

792807a444 nvme: fix infinite loop when aborting queued reqs
When we disconnect a qpair, part of the code path is
calling _nvme_qpair_abort_queued_reqs.  This takes
care of aborting any requests that were queued waiting
for slots to open on the submission queue.
It walks the STAILQ one by one and manually completes
them with ABORT status back to the caller.

But if the callback path submits another request, this
request may also get queued to the end of the queued_req
TAILQ.  This can result in an infinite loop.

The solution is to use an STAILQ_SWAP to a local, empty
STAILQ.  Then we ensure we only abort the requests that
were queued when _nvme_qpair_abort_queued_reqs() started
executing.

Fixes issue #1588.

I used the multipath.sh test to reproduce this on my local
system. If it ever dropped into the STAILQ loop in this
function, we would hit the infinite loop.  With this patch,
I confirmed locally that now we safely avoid the infinite
loop and the test passes.
