Currently we do not have any way to connect traces from different
modules in SPDK. This change modifies our trace library
and app/trace to handle adding relations between trace points
and a trace object.
Additionally this patch adds classes and fields to structs
inside trace.py to prepare it for future patches implementing
printing relation information.

In some cases a single virtually contriguos memory
buffer can be translated to several chunks of memory.
To make such translation possible, update structure
spdk_memory_domain_translation_result to use a pointer
to iovec.
Add a single iov structure or cases where translation
is always 1:1, it will make easier translation callback
implementation. For RDMA transport translation of address
is always 1:1, so treat iovcnt other than 1 as an
error.

Previous patches (5363eb3c) tried to work around the
32-bit unmap and write_zeroes LBA counts by breaking
up larger operations into smaller chunks of max size
UINT32_MAX lba chunks.
But some SSDs may just ignore unmap operations that
are not aligned to full physical block boundaries -
and a UINT32_MAX lba unmap on a 512B logical /
4KiB physical SSD would not be aligned. If the SSD
decided to ignore the unmap/deallocate (which it is
allowed to do according to NVMe spec), we could end
up with not unmapping *any* blocks. Probably SSDs
should always be trying hard to unmap as many
blocks as possible, but let's not try to depend on
that in blobstore.
So one option would be to break them into chunks
close to UINT32_MAX which are still aligned to
4KiB boundaries. But the better fix is to just
change the unmap and write_zeroes APIs to take
64-bit arguments, and then we can avoid the
chunking altogether.
Fixes issue #2190.

This library will provide functions that parse traces recorded by an
SPDK application. This includes merging traces from multiple cores,
sorting them by their timestamp and constructing trace entries spanning
across multiple buffers. All of these tasks are currently implemented
in the spdk_trace app, so most of its code will be moved here (this is
the reason for using C++).
The motivation for extracting this code to a library is to be able to
use it from places other than the spdk_trace app, specifically the
`scripts/bpf/trace.py` script.
The main reason for creating a separate library instead of extending
libtrace is to avoid pulling in all of its dependencies. ISA-L is the
most problematic, as we only build it as a static library, which makes
it impossible to use with dlopen (making it unusable in scripts).

When a subsystem is being deleted, we disconnect all qpairs
and when the last qpair for some controller is disconnected,
we start controller desctruction process. This process requires
to send a message to subsystem's thread to remove the controller
from the list in the subsystem and after that send a message to
controller's thread to release resources.
The problem is that the subsystem also destroys all attached
controllers. This order is unpredictable and we may get
heap-use-after-free or double free.
To fix this problem we can rely on the fact that the subsystem
can only be destroyed in incative state, that means that all
qpairs linked to the subsystem are already disconnected and
all controllers are already destroyed or in the process of
destruction.
spdk_nvmf_subsystem_destroy API is now can be asyncrhonous,

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).

This is the first patch in the patch series to control ANA states not only
as a unit of subsystem listener but also as a unit of ANA group and create
user preferred mapping between namespaces and ANA groups within a single
subsystem.
This patch adds anagrpid to both spdk_nvmf_ns and spdk_nvmf_ns_opts, and adds
ana_group array to spdk_nvmf_subsystem to count number of namespaces per ANA
group within a single subsystem. The size of the ana_group array is equal
with the size of the namespaces.
For each subsystem, allocate ana_group array regardless of the value of
ana_reporting of the subsystem.
For each namespace, at its creation, initialize anagrpid explicitly to be equal
with nsid by default and increments the corresponding entry of the ana_group
array of the subsystem regardless of teh value of the ana_reporting of thee
subsystem.
Hence the contents of the created ANA log page is not changed even if the
algorithm to crete ANA log page is changed.
Additionally this patch adds a unit test case that one ANA group
has multiple namespaces.

fini_start() is called for each bdev module before
iterating over all unclaimed bdevs to unregister them.
This allows bdev modules to behave differently during
each such unregister. Ex. unloading lvol store when
all lvol bdevs on it are unregistered.
Another use of this callback is to unclaim all bdevs
that can be at that point. Especially ones that will
not receive callback due to no bdev registered.
Ex. offline raid bdev, when some underlying bdevs are missing.
fini_start() being synchronous does not help in cases
where to release claim on the bdev, an asynchronous operation
is required. Ex. lvol store with no bdevs present, requires
async lvs unload to be called.
This patch adds async_fini_start flag for the bdev modules,
to be used when async fini_start is required. When done,
bdev module has to call spdk_bdev_module_finish_start_done().

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.

This patch adds the ability to chain multiple trace entries together to
extend the size of the argument buffer. This means that a tracepoint is
no longer limited to the size of a single entry, so it can have any
number of arguments, and their size is also not constrained to a single
entry.
Some limitations are still there: a tracepoint can have up to 5
arguments and strings are limited to 255 bytes. These constraints stem
from the definitions of tracepoint structures, which could be easily
modified to extend the limits if needed.
To record a tracepoint requiring larger buffer, aside from reserving
`spdk_trace_entry` structure, a series of `spdk_trace_entry_buffer`
structures are allocated too. Each of them acts as a buffer for the
arguments. To allow trace tools to treat the buffer structures
similarly to regular entries, they also have the `tpoint_id` and `tsc`
fields. The id is always assigned to `SPDK_TRACE_MAX_TPOINT_ID` to make
sure that a buffer is never mistaken for an entry, while the value of
`tsc` is always shared with the initial entry. This also provides a way
for the trace tools to verify if an entry is part of a chained buffer.

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.

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.

This patch allows tracepoint to record a variable number of arugments.
An additional function has been added,
`spdk_trace_register_description_ext()`, which allows the user to
register definitions for tracepoints specifying all the arugments that
they accept. Users can also call `spdk_trace_register_description()` to
register tpoints with a single argument (or none).
Currently, all of the tracepoint arguments need to be passed as
uint64_t.
The trace record functions use variable arguments and rely on tracepoint
description to know the order and the format of the arguments passed.
That means that the user needs to take care that they're always in sync.
Moreover, this patch extends the tracepoint entry size from 32B to 64B,
meaning that there are 40B that can be utilized for passing arguments,
which in turn means that there can be up to 5 arguments per tracepoint.

Note that DPDK also supports registering sigbus handlers,

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

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().

__builtin_clzll(0) is technically undefined, but
returns 64 on all currently tested architectures,
which is the desired value. So remove the
assert(datapoint != 0) and instead just set clz=64
for that case so that we aren't depending on
undefined behavior.

zipf is a power law probability distribution. When
applied to performance testing of block devices, it
will select blocks over the full range of LBAs, but
will more frequently select lower-numbered LBAs.
The theta parameter governs the distribution - higher
values of theta will concentrate the distribution on
a smaller number of LBAs.
Note that fio supports zipf, so adding it to SPDK
will enable our perf tools (bdevperf, nvme-perf) to
provide similar functionality.

We have some cases where libraries need the
spdk_bdev_module structure definition and a couple
of related APIs, but not everything else (i.e.
spdk_bdev, spdk_bdev_io), for purposes of avoiding
abidiff errors.
For example, nvmf creates a dummy spdk_bdev_module,
and then uses it with the spdk_bdev_module_claim_bdev
API to ensure multiple subsystems cannot add the same
bdev as a namespace.
But when nvmf includes bdev_module.h, it pulls in the
spdk_bdev structure definition as well. This means
when the spdk_bdev structure is modified, it requires
a major version bump since abidiff detects the
difference in the debug info.
Alternatives considered:
* We could add a specific suppression into our abidiff
script for nvmf and struct spdk_bdev, but it would be
a risk (albeit very very small one) that we could
add a real dependency on struct spdk_bdev in the future,
and the suppression would hide the difference.
* We could also break out bdev_module.h into multiple
header files, but the ways of doing that either result
in odd file naming, or modifying every bdev module to
include a new header.
* We could add a public bdev API to expose what the
bdev library needs, but that seemed even more intrusive
than this change. nvmf is kind of abusing the bdev_module
API here, and I'd prefer to not promote that kind of
usage by adding something to the bdev API.

The max_io_size transport option should be a power of 2 and be >= 8KB.
Max data tranfer size is defined in NVMe-oF spec as 2^(mdts cmd field) * 4KB.
Mdts cmd field is calculated as spdk_u32log2(transport->opts.max_io_size / 4096),
so max_io_size < 8KB results in mdts=0, which means no size limit (according to spec).
User can set max_io_size = 0 explicitly to allow no size limit.

Add a new zone state to represent an explicit open zone.
Many zoned specifications like ZBC/ZAC/ZNS have two different
zone states to represent an open zone: explicit open and
implicit open.
In e.g. ZNS, a zone is transitioned to explicit open when a
Zone Management Send is sent with a zone send action of open zone.
In ZNS, writing to e.g. an empty or closed zone, without first
sending a zone send action of open zone, will instead transition
the zone to implicit open.
The OCSSD specification only has a single open zone state.
In OCSSD, you can only transition to the open state by doing a write.
There is no separate function call to transition a zone to the open
state. Therefore, the OCSSD open state is most similar to the ZNS
implicit open state.
Since we cannot remove the SPDK_BDEV_ZONE_STATE_OPEN identifier,
for backwards compatibility reasons, make the SPDK_BDEV_ZONE_STATE_OPEN
identifier an alias to the new SPDK_BDEV_ZONE_STATE_IMP_OPEN identifier.

A very heinous error case is when a delete_io_sq or
delete_io_cq command fails when freeing a PCIe IO
qpair. In that case we return an error to the caller,
and the resources are not freed.
Instead of trying to 'fix' this error case, let's
just tell the user that if freeing an IO qpair fails,
the user should reset the controller and try again.
Resetting the controller will do one of two things:
1) The subsequent create_cq/create_sq will succeed,
at which point, trying to delete again should work
fine. (If it doesn't, it indicates some kind of
horrendous SSD.)
2) The subsequent create_cq/create_sq will fail,
at which point the entire ctrlr would fail and
need to be detached. This could result in some
leaked memory, but seems unavoidable.

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.

Aspects of bit fields are 'implementation defined'. On some platforms
alignment will occur if two adjacent fields are of different types. This
occurs in spdk_nvme_feat_async_event_configutation after the crit_warn
member which is effectively an int8_t, followed by an int16_t. There
isn't a generic way of changing the compiler's behaviour, so the best
options are:
- Change crit_warn to a uint32_t bit field and copy the value to/from
a spdk_nvme_critical_warning_state variable to use it. This requires
changes to code using the field.
- Adjust the structure definition to use smaller types to avoid the
problem. This preserves existing semantics, but the field order will
need to be reviewed if big-endian support is ever added (other places
in nvme_spec.h will need similar attention). A second reserved field
is required.
Use smaller types which seems the most straightforward option. Adjust
the use of the spdk_nvme_feat_async_event_configuration reserved fields
in lib/nvmf/ctrlr.c.
The new structure is binary compatible and the fields behave in the same
way, with the exception of an additional reserved field, so updating
CHANGELOG.md probably isn't necessary.

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

This API will be useful for use cases where multiple

of PCIe SSDs to those processes are based on some function
of the SSD's PCIe address.

reaches the device count there's no sharing so no resize of

Same thing is done on destruction. The code to free idxd

the idxd put channel function which is a much more logical

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.

The new design:
* Supports a generic batching capability in the accel_fw layer
that keeps track of hw accelerated vs sw commands based on
the capabilities of the engine and processes sw commands in the
generic layer while sending a list of commands (not a batch)
to the engines for processing.
* Batch completions are managed via the generic layer, when using
the accel_fw the engines only process commands. With DSA however,
if a list of commands is sent down it will use the DSA public
API to create and send batches but will rely on the generic layer
to complete the batch task itself. When using DSA directly, batching
works as usual (DSA handles batch completion).
* The engine function tables were greatly simplified by replacing
all of the individual entries (copy, fill, crc32c, etc) with one
`submit_tasks` function that is used to both send lists of tasks
for batches or just one task for single shot API.
* Internally batching is now used to re-submit tasks that were queued
for flow control reasons.

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 complement that, transports will now also have their own

Especially SPDK_INFOLOG() should not call spdk_log_get_flag() function,
instead rely on the log flag structure.
This caused performance degradation in places that used SPDK_INFOLOG
too extensively.
Due to nature of the macros, in the meantime new debug log in
iscsi was improperly named. This wasn't caught because of the
macros reliance on spdk_log_get_flag(), where if name wasn't
registered - no log was printed and no compilation occurred.
Going back to using the structures, gives immediate feedback
that there is no SPDK_LOG_ISCSI log flag.

Add an new API spdk_bdev_part_base_construct_ext() to pass not bdev but
bdev_name to fix the race condition due to the time gap between
spdk_bdev_get_by_name() and spdk_bdev_open(). A pointer to a bdev is
valid only while the bdev is opened.
In the new API, spdk_bdev_get_by_name() is included in
spdk_bdev_part_base_construct_ext() and the caller has to know if
the bdev exists or not. Hence spdk_bdev_part_base_construct_ext()
returns return code and returns the created part object by the double
pointer.
Another critical change is that base is just freed if spdk_bdev_open_ext()
failed with -ENODEV. The reason is that if we call spdk_bdev_part_base_free()
for that case, the configuration is removed by the registered callback
and so bdev_examine() will not work.
The following patches will replace spdk_bdev_part_base_construct()
by spdk_bdev_part_base_construct_ext() for the corresponding bdev
modules.

intentions of providing much better performance for allocating

array for a cleared bit can become expensive so the spdk_bit_pool
will provide an ability to track extents of recently cleared
bits.
This initial commit does not adding the tracking yet - it is strictly
a wrapper around spdk_bit_array with enough functionality to replace
the use of spdk_bit_pool in SPDK blobstore with equivalent performance.
This will allow us to switch blobstore to use this minimal
wrapper first, and then iteratively improve spdk_bit_pool to provide

After supporting ANA reporting by default, Linux kernel 5.3 reported
error when parsing NVMe ANA log. The newer kernel fixed the issue
but we should optionalize ANA reporting feature to avoid error for
Linux kernel 5.3 or before.
Add a bool variable ana_reporting to struct spdk_nvmf_subsystem
and disable ANA reporting and initialization of related variables
if it is false. We can expose MNAN (Maximum Number of Allowed
Namespaces) even if ANA reporting is disabled. But MNAN is not
required if ANA reporting is disabled. So do not set MNAN if it is
false too.
Add a public API spdk_nvmf_subsystem_set_ana_reporting() to set
ana_reporting by the nvmf_create_subssytem RPC.
The next patch will add ana_reporting to nvmf_create_subsystem RPC.
