Recent work identified race conditions having to do with the
dynamic flow control mechanism for the idxd engine. In order
to both address the issue and simplify the code a new scheme
is now in place. Essentially every DSA device will be allowed
to accomodate 8 channels and each channel will get a fixed 1/8
the number of work queue entries regardless of how many
channels there are. Assignment of channels to devices is round
robin and if/when no more channels can be accommodated the get
channel request will fail.
The performance tests also revealed another issue that was
masked before, it's a one-line so is in this patch for convenience.
In the idxd poller we limit the number of completions allowed
during one run to avoid the poller thread from starving other
threads since as operations complete on this thread they are
immediately replaced up to the limit for the channel.

Previously only a single thread could submit abort commands for admin
commands and it was the thread of the corresponding controller.
When we support multipath, we need to traverse the list of controllers
to which the target admin command is submitted. Threads of controllers
may be different.
On the other hand, the previous implementation made the I/O flow very
clean, but the I/O flow will not be clean if there are many controllers
and the subsystem does not have its thread.
This patch changes the policy so that any SPDK thread can submit abort
commands for admin commands.
Then when multipath is supported, we will be able to traverse the
list of controllers simply on the current thread to abort either I/O
command or admin command.
We already are able to submit any admin command on any thread anytime
including abort command. Hence this will not cause any issue.

Before this patch idle_tsc was sum of all idle tsc of all
threads running on a reactor.
There are cases when no threads are present on the reactor,
and _reactor_run() spins doing nothing.
To give more accurate representation of the reactors state,
the idle_tsc now adds time spent doing idle spinning.

tsc_last value is used to update thread stats
during _reactor_run(). See:
spdk_thread_poll(thread, 0, reactor->tsc_last);
If no threads were present on the reactor,
this value got outdated and resulted in
adding time reactor spent with no threads to
stats of the first thread placed on that reactor.
This patch fixes thread stats by making sure
that argument to spdk_thread_poll() is up to date.

This patch does not change the UT in functional way.
Added accounting of last_tsc and spdk_get_ticks() similar
to the real application.
First the reactor_run() [not _reactor_run()] starts
reactor->tsc_last to current time. UT now set it at the start
and never touch it again directly.
Second the spdk_get_ticks() is updated to the elapsed time
to simulate flow of time, and make sure that its further
usage is up to date to the current time.

Use the macros for red black tree provided by Free BSD to manage

Allow RB_INSERT() to insert elements with duplicated keys by changing
the compare function to return 1 if two keys are equal.
Check the return code of RB_INSERT() because this is the first use case
for RB tree macros in SPDK. We did the same for RB_REMOVE() by
adding another temporary variable but we remove it from this patch
because it is not so important compared with RB_INSERT().
When a timed poller is inserted, update the cache for the closest (leftmost)
timed poller only if the tree was empty before or the closest (leftmost)
timed poller was actually changed. We do not have to use RB_MIN()
because all duplicated entries are inserted on the right side.

This change is a preparation to first dequeue the closest timed poller
always when it is expired. Previously the poller_remove_timer() calls
were not consistent and difficult to follow.
spdk_poller_pause() sets poller to PAUSING even when it in RUNNING
and move it to PAUSED after returning from its context.
If spdk_poller_pause() and spdk_poller_resume() are called while poller
runs, it is moved to WAITING. Hence thread_execute_poller() and
thread_execute_timed_poller() ignore such cases.

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.

We cannot rely on DSM/DEALLOCATE as a write zeroes
alternative, even if DLFEAT reports that deallocated
blocks will be read as all zeroes. DEALLOCATE is
advisory, meaning that blocks may not actually be
deallocated. In cases where they are not deallocated,
they will not be read back later as zeroes.
QEMU 6.0 started reporting DLFEAT as returning zeroes
for deallocated blocks but for some of our write
zeroes tests, blocks aren't actually deallocated.
We may be able to add quirks in the future if we know
that a controller reliably deallocates blocks, but
for now we need to revert this completely.
Note that since bdev/nvme module now does not support
write zeroes in any cases, we need to disable the
write zeroes call in the unit tests.

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.

To avoid this calculation being performed everywhere, create a helper

a user can easily get the number of zones.

This patch addresses couple issues:
1) Before issuing the md syncs the previous steps in test left
blob state in dirty state already. The resize never had a chance
to apply. This patch adds a proper md sync and polls for completion.
2) Changing blob state is something that should be done via API.
In order for dirty state to apply immidietly set_xattr is now used instead.
3) Verify test state in callbacks to make sure not only the number of
completions is correct, but their order.
This patch is introduced because of the test originally worked
only because of the extent pages always writing out its pages.
The second sync always was delayed because of this.
Meanwhile that should not be the case, since no MD or EP modification
was done.
Later in the series Extent Pages are fixed, but this test remained incorrect.

Test scenario is as follows.
Some iSCSI initiator sends a Data-OUT PDU sequence such that the size of
the data segment of any Data-OUT PDU is not block size multiples.
Test if such complex Data-OUT PDU sequence is processed correctly.
Desired Data Transfer Length is 5 * SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH / 2.
Number of Data-OUT PDUs is 4. Length of the data segment of the first two PDUs are
SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH / 2 - 4. Length of the data segment of the
third PDU is SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH. Length of the data segment
of the final PDU is SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH / 2 + 8.
Three data buffers should be used and three subtasks should be created and submitted.
The test scenario assume that a iscsi_conn_read_data() call could read
the required length of the data and all read lengths are 4 bytes multiples.
The latter is to verify data is copied to the correct offset by using data patterns.

This was to differentiate the two cases, ctrlr is statically assigned

Hence create a subtask after reading data segment.
If LUN is removed while processing the Data-OUT PDU, the corresponding

The API spdk_nvme_ctrlr_free_io_qpair() returns immediately if the
passed qpair is NULL, but calling spdk_nvme_ctrlr_free_io_qpair()
with NULL should be avoided.
This patch cleans up the code to ensure that nvme_ch->qpair is NULL if
disconnected and spdk_nvme_ctrlr_free_io_qpair() is called only if
nvme_ch->qpair is not NULL.
Then add a test scenario that two reset requests were submitted
simultaneously and the first reset request failed and then the second
reset request also failed. This verifies the refactoring done in the
next patch.

Add support for zoned namespaces in the bdev/nvme module.
Query the namespace type, and if a zoned namespace is found, set the
bdev struct members needed by the bdev_zone.h APIs.
Note that while vbdev_zone_block and bdev_ocssd have zone locks,
bdev/nvme does not need any kind of zone lock, because NVMe ZNS
supports append natively.
The whole point of the zone append command is that you don't need any
locks, even when having multiple writers, since the drive will return
back the Assigned LBA where the blocks were actually written.
If a SPDK application will utilize writes instead of zone appends,
the SPDK application itself will need a per zone lock in order to
make sure that there is only one outstanding write.
Adding zone locks in bdev/nvme would reduce the performance of zone
appends, for no reason at all.

The recent refactoring removed the destruct poller and change the
reset processing to destruct ctrlr after its completion by conditionally
sending message.
But differentiating callback function is difficult if we reset multiple
ctrlrs.
If nvme_bdev_ctrlr->destruct is set, any new reset cannot start. So we can
use an new variable and always execute the callback function.
Add an new variable pending_destruct to struct nvme_bdev_ctrlr, and set
pending_destruct if ctrlr->ref is zero and ctrlr->destruct is true, and
then start destruct ctrlr if ctrlr->destruct_after_reset is set after
clearing pending resets.

Leverage SO_INCOMING_CPU to get the CPU affinity of connections

which aims to utilize cache locality.
From our test:
6 P4600 NVMe on target,target uses 8 cores, NIC irqs are bound to
these 8 cores, and initiator side uses 24 and 32 cores,
we can get 11%~17% randwrite performance boost for posix, and 8%~12%
for uring.

On some platforms, GCC identifies that opts.io_queue_requests is used
uninitialised in bdev_nvme_create_qpair due to the stub function
spdk_nvme_ctrlr_get_default_io_qpair_opts which would normally zero the
qpair opts. Whether the warning appears is likely to be determined by
how effectively the platform garbage collects unused code.
Replace the stub with a minimal implementation that zeros the qpair
opts to avoid the warning.

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.

The tests use values that are outside of the MIN/MAX range, which

to avoid overflow and recombined as a string.
Verified using the unit tests on two different architectures and with

The env layer will only even probe devices that have

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

This API will be useful for use cases where multiple

For flow control reasons we have to resize the bit arrays we
use to manage flow as channels come and go. However since
channels are assigned to devices, until the channel count
reaches the device count there's no sharing so no resize of
the array is needed. So, when we use a device for the first
time there's no need to run through the rest of the channels
and re-balance.
Same thing is done on destruction. The code to free idxd
specific resources was moved from the rebalance function to
the idxd put channel function which is a much more logical
place for it as well.

Config #1 remains what is shown as an example in the spec. Change
config #0 to just have 1 work group and 1 work queue all backed
by 4 engines. As the majority of initial use cases will not be
implementing separate priorities and/or different back end
targets (mem, pmem, etc) having just 1 group and work queue makes
the most sense as it allows the silicon to decide which engine to
use.
Also, having multiple work queues spreads out the available
entires such that if we're not using all of the work queues then
we're not using all of the resources. As channels are created
they are assigned the next available device. As a channel is
assigned a device that is already in use it will round robin
work queues. If then, for example, we have 16 devices then only
the first work queue will ever be used for the first 16 threads
which seems and if there are even just 2 work queues per device
it would take 32 threads to use all of the resources at the
device.
By haing just one work queue per device we always have the max
number of work queue entries available regardless of how many threads
are being used.

If the CUnit include files are located through CFLAGS rather being
in one of the system include directories, then the version test will
fail and blob.c unit tests will be skipped. Specify CFLAGS as part of
the CC command.
If the version check fails, clean won't be run to remove any left over
artifacts. This can occur if CUnit is being built externally and gets
cleaned before SPDK. Add an extra definition (ALL_DIRS) to control
compilation, so that clean will always be run.

`--cpumask` argument for vhost controller creation was
untested. This patch specifies this argument and verifies output
under following conditions:
- no cpumask, resulting in it being equal to the app cpumask
- cpumask equal to app cpumask
- single core
- single non-main core
- two cores
It was motivated by recent changes to reactor code affecting
vhost without it being caught by CI. See commit 7cc83b62.

the moment when IO qpair is added to a controller due to e.g.
expired keep alive timer. Part of the qpair destruction process
is change of qpair's state to DEACTIVATING and removing it
from poll group. We can check admin qpair's state and poll
group pointer before sending a message to poll group's thread
and fail connect 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.

Current SPDK thread library has a issue which occurs if there is
a race between exiting thread and unregistering io_device.
For example, there are two threads. Thread 1 registers a device
and thread 2 gets a channel of the device. Then if thread 1 starts
exiting and unregisters the device, and then thread 2 puts the channel,
thread 2 sends a message to thread 1 to complete releasing the device,
thread 1 already moved exited. Hence thread 2 failed to send the
message.
This patch fixes the race issue. The code is verified by adding
a unit test case.
In detail, add a count, unregistering_dev, to struct spdk_thread,
increment it if a callback is specified to spdk_io_device_unregister(),
and then decrement it in _finish_unregister(), and thread_exit()
checks if it is zero.
The contents of struct spdk_thread is changed but it is not public
data structure, and hence suppress it for ABI testing.

Add an new function iscsi_portal_group_resume() and add an new parameter
pause to iscsi_portal_group_open(). They will be used in the following
patches to pause listening portals while target nodes are created at
start-up because Windows hosts do not retry login.
Pausing and resuming portal group is possible because we can unlisten
temporarily by simply not calling accept(). Any inbound connection
requests are queued to the backlog and once the backlog queue is full,
further inbound connection requests are simply dropped. If we restart
calling accept(), we will dequeue the backlog and be ready for more
connecitons.

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.
