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

If the start is indeed valid, we might fetch a new SGE,

However, this second alignment check is done unconditionally,

Add a function to get the number of max open zones for a zoned
namespace.
The value inside the identify namespace struct is a 0's based value,
where 0xffffffff means unlimited.
If unlimited, the addition will overflow and return 0,
which is the intended value to represent unlimited for this API.

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.

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.

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.

Zone Append differs from a regular write, in that the command is not

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.

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.

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.

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.

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.

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.

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.

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).

Add a new state in the SPDK NVMe state machine in order to fetch

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.

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

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.

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.

Since the command set identifier might be accessed at several
different states in the nvme state machine, cache it so that
we don't need to loop through the ns id desc list every time.
This is similar to how other identify fields are cached using
nvme_ns_set_identify_data().
None of the identifiers in the desc list (including the new CSI)
can change over the life time of a namespace, so caching them
should be safe.

If the nvme completion was an error, the function will return,
so there is no reason for an else statement.
In fact, the else statement in nvme_ctrlr_identify_ns_async_done()
differs from the coding style used in other nvme_ctrlr_identify_*
functions, and arguably makes the code harder to read.

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.

In cases where the SPDK nvme driver is being used as a validation/test
vehicle, users may need to allocate a currently unused qid that can be
used for creating queues using the raw interfaces. One example would be
testing N:1 SQ:CQ mappings which are supported by PCIe controllers but
not through the standard SPDK nvme driver APIs.
These new functions fulfill this purpose, and ensure that the allocated
qid will not be used by the SPDK driver for any future queues allocated
through the spdk_nvme_ctrlr_alloc_io_qpair API.

This is an attempt to workaround a kernel data race spotted in #1275.
We have to delay our VFIO interraction until after the kernel handles
the PCIe hotremoval. Otherwise we risk having a deadlock inside the
kernel. We could put a dummy delay in SPDK hotremove routine, but we
don't know exactly how long we have to wait, so wait for the VFIO
hotremove notification to arrive instead. From what I understand it
is always sent after the kerner already releases the critical locks.
This patch breaks hotremove for VFIO devices when running with
DPDK version < 18.05, but those reached EOL already and their support
is removed from SPDK later within this series.
It would be nice to wait for this VFIO notification inside lib/env_dpdk
e.g. inside the detach function, but we don't know there why the
detach is happening. It could be triggered by a user RPC, not physical
device hotremoval.

A new API spdk_nvme_ctrlr_cmd_abort_ext() gets cmd_cb_arg as a
parameter, and use it to abort requests whose cb_arg matches cmd_cb_arg.
The caller can set the parameter qpair to NULL if it wants to abort
requests on admin qpair.
Hold ctrlr->ctrlr_lock throughout because abort request is submitted
to admin qpair.
The API is not critical for performance, and so initialize parent
data first.
The API is for a specific qpair, and so hold SQID in the parent,
and it is copied to the children. On the other hand, CID is set
to child when request to abort is found.
Use an new helper function nvme_transport_qpair_iterate_requests()
to add abort request for each outstanding request which has
cmd_cb_arg as its callback context.
The case is possible such that the request to abort is not outstanding
yet but queued. Hence abort queued requests which has cmd_cb_arg
as its callback context too, but it is done only if there is no error
so far.
If only queued requests are aborted and there is no outstanding
request to abort, complete with success synchronously.
If there is no outstanding or queued request to abort, return -ENOENT.
When any abort request is submitted, the difference between success
and failure is only bit 0 of CDW0 according to the NVMe specification.
We cannot the existing helper functions nvme_request_add_child() and
nvme_cb_complete_child() but can use nvme_request_remove_child().
nvme_qpair_submit_request() may use only nvme_request_remove_child()
from these three helper functions. Hence we use req->parent as other
types of request do.

Use another list dedicated to hold queued requests being aborted
to avoid potential infinite recursive calls.
Add a helper function nvme_qpair_abort_queued_req() to move requests
whose cb_arg matches from qpair->queued_req to qpair->aborted_queued_req.
Then nvme_qpair_resubmit_requests() aborts all requests in
qpair->aborted_queued_req.
The first idea was that nvme_qpair_abort_queued_req() aborts queued
requests directly. However, this caused infinite recursive calls.
Hence separate requesting abort to queued requests and actually
aborting queued requests.
The detail of the infinite recursive calls is as follows:
Some SPDK tool submits the next request from the callback to the completion
of a request in the completion polling loop. For such tool, if the callback
submits a request and then aborts the request immediately, and the request
could not be submitted but queued, it will create infinite recursive calls
by request submit and abort, and it will not be able to get out of
completion polling loop.

To abort requests whose cb_arg matches, add child abort request greedily.
Iterating all outstanding requests is unique for each transport but
adding child abort is common among transports, and adding child abort
is replaceable by other operations.
Hence add qpair_iterate_requests() function to the function pointer table
of transport, and pass the operation done in the iteration by a
parameter of it.
In each transport, the implementation of qpair_iterate_requests() uses
TAILQ_FOREACH_SAFE() for potential future use cases.

Each request has a callback context as cb_arg, and the callback to
nvme_complete_request() for the completed request may reuse the context
to the new request.
On the other hand, TCP transport dequeues tcp_req from
tqpair->outstanding_reqs after calling nvme_complete_request() for
the request pointe by tcp_req.
Hence while nvme_complete_request() is executed, tqpair->outstanding_reqs
may have two requests which has the same callback context, the
completed request and the new submitted request.
The upcoming patch will search all requests whose cb_arg matches to
abort them. In the above case, the search may find two requests by
mistake.
To avoid such error, move dequeueing tcp_req from tqpair->outstanding_reqs
before calling nvme_request_complete(). One exception is the case that
only nvme_tcp_req_put() is called. For the case remove tcp_req from
tqpair->outstanding_reqs before calling nvme_tcp_req_put().

When the user requests a non-default command set configuration, via the
probe_cb() supplied to spdk_nvme_probe(), which is not supported, then
the controller initialization will not proceed.
This patch changes that behavior into falling back to the NVM command
set and continue with the controller initialization. It is done by
assigning the NVM command set to opts.command_set such that the user
knows in attach_cb() with which command_set the controller is
configured/enabled.
The fallback is needed since the user does not have access to the
controller capabilities register. The strategy left for the user is thus
to try. However, this is an issue, as the user only has one attempt, as
subsequent calls to spdk_nvme_probe() will not trigger probe_cb() for
the controllers whose initialization did not proceed.

Each request has a callback context as cb_arg, and the callback to
nvme_complete_request() for the completed request may reuse the context
to the new request.
On the other hand, RDMA transport dequeues rdma_req from
rqpair->outstanding_reqs after calling nvme_complete_request() for
the request pointed by rdma_req.
Hence while nvme_complete_request() is executed, rqpair->outstanding_reqs
may have two requests which has the same callback context, the
completed request and the new submitted request.
The upcoming patch will search all requests whose cb_arg matches to
abort them. In the above case, the search may find two requests by
mistake.
To avoid such error, move dequeueing rdma_req from rqpair->outstanding_reqs
before calling nvme_request_complete().

This patch tries to solve the out of order
call back handling for cmd sending and the incoming pdu handling.
Normally, the cmd call back will be called before
receving the next PDU from the target if the application
uses the sync manner.
With the uring implementation, after sending the
cmd to the target, we may have the following scenerio:
(1) Firstly receive the incoming pdu(e.g., CapsuleResp pdu, C2hdata pdu)
due to the group polling read event.
(2) Secondly execute the callback function related with NVMe command sending.
This means that the data from the initiator is really sent out to the target,
and the target receives, then sending back the data to the initiator. But the
uring io_uring_cqe event is not handled, thus if we execute
(1) first, it will clean the data structures related with nvme_tcp_req, and the
nvme_tcp_req will be used for other purpose. Then causes wrong behaviour like
the following:
"Rand Write test failed at QD=128 because fio hangs with the following error:
nvme_tcp.c: 971:nvme_tcp_capsule_resp_hdr_handle: *ERROR*:
no tcp_req is found with cid=66 for tqpair=0x7f23d8001710".
And this patch can address this issue.

the controller memory buffer by default, it will use
memset and SSE instruction when copying NVMe command
to the submission queue entry or zero the whole

the AVX2 instuction will be used if the CPU can support

The spdk_opal_supported() is redundant with spdk_opal_dev_construct(),
because we only return the spdk_opal_dev structure when the drive
can support OPAL feature.

Do not make attempt to resubmit failed send/recv WR, instead
report and error to the upper layer (in case of new request) or
fail a qpair (in case of active polling).
In the case of failed ibv_post_send and disabled `delay_cmd_submit`
nvme_rdma_qpair_submit_request returns an error to the caller.
The caller completes failed request but RDMA layer still keeps
it in a send queue. Later RDMA layer can send the corresponding
WR and notify the upper layer about the completion of the request
for the second time.
