68063cd8b6 lib/blob: force md update during decouple parent
Fixes #1933

When decoupling parent the updated parent_id was
not persisted to the blob if it was a snapshot.
Due to having md_ro set to true, blob_set_xattr()
failed.

Later on the incorrect parent_id could cause troubles
like in the github issue, when deleting that snapshot.

This patch adds return code check for blob_set_xattr
and forces md_ro to false during blob md sync.

Since some of code paths are shared between decouple,
inflate and clone operations, the final callback for them
is doing revert of the original md_ro.

e5c3791c4e lib/nbd: Process NBD_CMD_DISC according to the NBD protocol
After this patch, nbd will no longer receive any requests if
NBD_CMD_DISC is received. But it will handle the  requests
already received.

Previously we called spdk_bdev_abort() for NBD_CMD_DISC and
it will reply to the rest requests in the channel of this bdev.

But there should be no reply to NBD_CMD_DISC. Hence we silently
discards requests after NBD_CMD_DISC.

d8843dccc5 nvmf/reservation: register new registrant when IEKEY is enabled
The specification says:
"A host may replace its reservation key without regard to its registration
status or current reservation key value by setting the Ignore Existing Key
(IEKEY) bit to '1' in the Reservation Register command."

So for this case we treat it as a new registrant, also add UT to cover
the added cases.

814cd25882 nvmf: optimize log level for unsupported feature IDs and invalid property offset
Since we are using NVMf fabric library to emulate a PCIe based SSD via
vfio-user target, so there maybe some commands that are related with
PCIe SSD only, such as set/get features with interrupt coalescing
and Interrupt Mask Set/Interrupt Mask Clear registers.  Even the
NVMf library doesn't support that, it is not a fatal error to Host
NVMe driver, so here we use the info log instead of error log for
this case so that to avoid noise logs.

Fix #2036.

e45450d28f thread: spdk_get_io_channel() use i->dev as the search key
In current implementation, io_channel list will be accessed by
spdk_for_each_channel() and spdk_get_io_channel(). We will try to
accelerate spdk_get_io_channel() in the following change "thread: speed
up io_channel lookup by using rbtree" by changing io_channel from list
into RB tree.

To make it cleaner, we prefer to use ch->dev as the key for the
io_channel RB tree instead of ch->dev->io_device. This patch makes
spdk_for_each_channel() use the i->dev to find the expected io_channel.
And the io_device in structure spdk_io_channel_iter is not needed in
spdk_for_each_channel_continue() but we keep it for the compatibility of
spdk_io_channel_iter_get_io_device().

After this patch, spdk_for_each_channel() has to access both io_device
list and io_channel list, and spdk_for_each_channel_continue() still has
to access only io_channel list.

Both io_device list and io_channel list will become RB tree. Hence
performance degradation will be negligible. spdk_for_each_channel() is
not so performance critical than spdk_get_io_channel().

f95bd3b6c7 lib/idxd: change how we complete batch desc
Previously we used a counter of our own to make sure all batch
elements plus the batch itself were done before we freed the batch.
This was due to some observations early on that the batch desc
could complete before the individual elements and a lack of clarity
as to whether this was due to the simulator or the fact that
we poll on completions and could therefore "see" completions in
a different order at that time (we were using bit arrays to poll).

Now we use an ordered (in time) list to poll locations so if we
instead put the elements on the list first and then the batch desc
itself we are assured to always "see" them in order provided the
underlying device meets spec which there's no reason to assume it
does not.

This simplifies things a bit at the same time and still assures
that we call list calbacks in order and then the batch callback
without "special" handling.

320ab72fb5 util: Add macro SPDK_SIZEOF_MEMBER to get size of a member of a struct
We find a few files to get the size of a member of a struct. How to
do it is a little complex. So add a macro to do it will be helpful
to read the current code and develop new features.

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

a066f0c3fb nvme: Fix the bug that assumed ANA group descriptor is 8-bytes aligned
This fix is as same as for NVMe bdev module.

If a ANA log page has two or more ANA group descriptors, the second
or later of ANA group descriptors will not be 8-bytes aligned.
Then runtime error would occur as follows:

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

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

2ed914f8ea idxd: Add the kernel idxd support
This patch is used to add the kernel idxd support.

Without this patch, we can use userspace idxd driver
under accel_engine library (module/accel/idxd/accel_engine).
With this patch, we can also kernel idxd driver under the
accel_engine library.

Our approach is implementing a wrapper library to use IDXD
device by leveraging the kernel DSA driver in SPDK idxd library
(lib/idxd).

Then users can leverage the RPC later to configure how to
use the DSA device by user space driver or kernel driver.

In this patch, our approach is to use the idxd-config library
to export the WQs (Working Queues) exported by the kernel.

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:

a5999f637a scheduler_dynamic: prioritize lowest lcore id for active threads
Before this patch _find_optimal_core() returned
1) any core that could fit the thread
2) if current core was over the limit, the least busy core
3) current core if no better candidate was found

Combined with _get_next_target_core() round-robining
the first core to consider, resulted in threads being
unnecessarily spread over the cores.

This patch only places threads on lower lcore id,
or when current core is over limit then any core that can fit it.

Next patch will remove round-robin logic to always start with
lowest lcore id.

d2ed0f45e7 scheduler_dynamic: scale up core load when moving thread
Before this patch the idle time of a core was increased
by the amount of busy time of thread that was moved out.
No assumption was made as to how the remaining threads,
would behave during next scheduling period.

This approach is fine, as over multiple scheduling periods
we'd arrive at a point where threads could do no more work
or all cores would be busy.

Yet this requires multiple scheduling periods to sort out
the threads.
Later in the series core_load will be used to determine,
when to start moving threads out of the core. So changing
this assumption will allow for faster responses to thread load,
at cost of sometimes spreading threads too much briefly.

With this patch, we are assuming that threads remaining
on the core will do proportionally the same amount of work
during next scheduling period.

See an example illustrating the change:

Before moving Thread1
Thread1	Busy 80		Idle 20		Load 80%
Thread2	Busy 60		Idle 40		Load 60%
Core	Busy 140	Idle 60		Load 70%

After moving Thread1 out (original code)
Core	Busy 140-80=60	Idle 60+80=140	Load 30%

After moving Thread1 out (this patch)
Core	Busy 140-80=60	Idle 60-20=40	Load 60%

11c9b3960b scheduler_dynamic: move thread to least busy core
In cases when all cores are already doing too much work
to fit a thread, active threads should still be balanced
over all cores.

When current core is overloaded, place the thread
on another that is less busy.

The core limit is set to 95% to catch only ones that are
fully busy.
Decreasing that value would make spreading out the threads
move aggressive.

Changed thread load in one of the unit tests to reflect the
95% limit.

spdk_bdev_unregister() already holds g_bdev_mgr.mutex when removing

spdk_bdev_close() had not held g_bdev_mgr.mutex. What we want to lock
is only when removing name from name tree, that is, calling
bdev_name_del() in bdev_unregister_unsafe(). However, we need to
keep hierarchical lock ordering. Hence get and free g_bdev_mgr.mutex
outside of bdev->internal.mutex.

6cc3169677 lib/trace: chain entries to extend their buffer size
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.

example when a controller is hot removed.  So even
if SQ or CQ deletion fails, continue with freeing

There is really nothing the application can do to
account for this failing anyways.

Upcoming patches will add additional checks to

ce60606dbc iscsi: Fix data digest degradation by restoring the original code
Due to the recent changes for non block size multiples write I/O,
the data digest feature was degraded. If Linux iSCSI host enables
data digest and tries to detect LU from SPDK iSCSI target, data
mismatch error is detected and the connection is disconnected
unexpectedly.

The cause was that pdu->data_valid_bytes was not set for non-write
response PDUs which have a data segment.

iscsi_pdu_calc_data_digest() has been used only for non-write response
PDUs. Hence we did not need to change iscsi_pdu_calc_data_digest().

Restore the original implementation of iscsi_pdu_calc_data_digest().

Additionally, to avoid future degradation, rename the related
functions to iscsi_pdu_calc_partial_data_digest() and
iscsi_pdu_calc_partial_data_digest_done(), and add comments for
clarification.

This fix was verified by the reporter.

Fixes #2029.

SPDK NVMf target will disconnect ADMIN queue pair due to association
timer timeout, and for vfio-user transport, the ADMIN queue pair
connection is associated with the socket connection, so when probing
the NVMe controller again, because there is no active ADMIN connection
for fabric register R/W commands, it will cause segment fault.

Here we set the association timeout value to 0 for vfio-user transport,
so that the ADMIN connection will not be disconnected when shutdown the
controller, the ADMIN queue pair will be disconnected when the socket
connection breaks.

563f69ebe8 bdev: spdk_bdev_get_by_name() hold mutex itself while traversing bdev name tree
spdk_bdev_register() and spdk_bdev_add_alias() had not held mutex when
adding bdev name or alias to global bdev name tree. This bug caused unexpected
error when traversing global bdev name tree.

The next patch will fix the bug. This patch is a preparation for the fix.

spdk_bdev_get_by_name() had not held mutex while traversing bdev
name tree. The major callers to spdk_bdev_get_by_name() had held mutex
when calling it. However, this was not clear.

Factor out the internal of spdk_bdev_get_by_name() into a helper
function bdev_get_by_name() and then change spdk_bdev_get_by_name()
to lock and unlock when calling bdev_get_by_name().

Then replace spdk_bdev_get_by_name() call in spdk_bdev_alias_add() and
bdev_register() by bdev_get_by_name() call.

spdk_bdev_get_by_name() call in spdk_bdev_examine() is not changed.
This is called only from JSON RPC and not related with the bug. So
we want to fix only unlocked access to global bdev name tree.

typically treat it as a catastrophic failure (i.e. it won't

So instead when this situation occurs, start a poller for
the connect request.  We will continue to retry processing
it until the subsystem is ready to handle it.

    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

10808e45d4 idxd: refactor flow control for idxd engine
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.

b503ef4fa0 nvmf: Fix heap-use-after-free when poll_group_remove() is called after ctrlr is freed
When a qpair is destroyed and the qpair is the last,
_nvmf_ctrlr_free_from_qpair() (in lib/nvmf/nvmf.c) sends two messages,
one is for _nvmf_ctrlr_destruct() and another is for
_nvmf_transport_qpair_fini().

We do not know which of two completes earlier.

_nvmf_ctrlr_destruct() frees the qpair->ctrlr in the end.
On the other hand, _nvmf_ctrlr_free_from_qpair() calls
spdk_nvmf_poll_group_remove() in the end, and spdk_nvmf_poll_group_remove()
accesses the qpair->ctrlr to free queued requests to the qpair.

Before one recent change, spdk_nvmf_poll_group_remove() had been called
before _nvmf_ctrlr_free_from_qpair() was called.

Hence extrace the operation to free queued requests from
spdk_nvmf_poll_group_remove() and inline it into _nvmf_qpair_destroy().

Fixes one showstopper error to investigate the issue reported in #1819.

127fc0d0c3 scheduler_dynamic: consider any core for the thread
Previously core load was only considered for main lcore.
Other cores were used based on cpumask only.

Once an active thread was placed on core it remained there
until idle. If _get_next_target_core() looped around,
the core might receive another active thread.

This patch makes the core load matter for placement of any thread.
As of this patch if no core can fit a thread it will remain there.
Later in the series least busy core will be used to balance
threads when every core is already busy.

Modified the functional test that depended on always selecting
consecutive core, even if 'current' one fit the bill.
Later in the series the round robin logic for core selection
is removed all together.

Fixed typo in test while here.

Note: _can_core_fit_thread() intentionally does not check
core->interrupt_mode and uses tsc. That flag is only updated
at the end of balancing right now. Meanwhile tsc is updated
one first thread moved to the core, so it is no longer
considered in interrupt mode.

60b655aa91 scheduler_dynamic: simplify thread balancing logic
When picking a path to go down with a thread,
conditions unnecessarily piled up.

Instead do it either of two ways:
- move idle threads to main core
- find best core for active threads and move them there

There is no need to worry about cpumask of the thread,
since _find_optimal_core() will always return a core
within the cpumask.

If the found core is the same one as the current,
_move_thread() won't perform any action.

f301d156f1 lib/trace: variable number of tracepoint arguments
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.

164bfddf24 nvmf: don't set aerl=0 for non-discovery controllers
Commit b7cc4dd added support multiple AERs, but didn't
remove the code that hardcodes aerl=0 for non-discovery
controllers.  So even though the target now supports
multiple AERs, we never indicate that for non-discovery
controllers.

The spec also recommends that implementations support
a minimum of 4 AERs - so the current behavior is not
recommended.

It seems that at least on Windows (when testing with
vfio-user transport) we see the limit get exceeded
which results in ERRLOGs.  Let's keep the ERRLOG there
for now, assuming that once we report we support 4

6aa6bfdda3 nvmf: use DEBUGLOG for unsupported features and log pages
We cannot control what the host may send to the target.
For example, we have empirical evidence that Windows
will send vendor-specific IDs for features and log pages
(when testing with the vfio-user target transport).

So let's change the ERRLOGs in these cases to DEBUGLOGs.

Fixes issues #2004, #2007, #2008.

c5432752b7 nvmf/vfio-user: eliminate insert_queue function
When creating queue pairs, the original code uses a stack
queue variable and copy it to queue pair in insert_queue
function, the coming changes in libvfio-user doesn't expose
dma_sg_t data structure any more, we need to change it to
a pointer and allocate memory for it, so here we eliminate
insert_queue function as a preparation.

59c8bb527b nvme: do not try to resubmit requests on error
If the transport returns error when polling for
completions, it gets to a uint32_t and we end up
trying to resubmit all of the requests that are
currently queued.  But that's not correct - if
the transport returns an error we shouldn't be
trying to resubmit requests at all.

While the req->data only contains the first iov, if req->iovcnt is
larger than 1, the req->data may not hold the complete log page; and
even worse, the log page result may be written to invalid address and
cause memory corruption.
