Orderings of portal group create operation are diferrent between
config file and JSON-RPC. Unification is necessary for correct
concurrency control and the global accept poller like NVMf-tgt.
Hence unify the ordering of operations in this patch.
Common ordering of portal group create operation between configuration
file and JSON-RPC after this patch is the following:
- create a portal group
- create portals
- add the portals to the portal group
- open the portals of the portal group
- add the portal group to the global portal group list
After this patch, the gap between listening socket and accepting socket
will be increased a little when portals groups are creted by config file.
However this will cause no issue because of the TCP backlog and resend
mechanism.
Besides, necessary concurrency control is added and minor refactoring
is done.
About portal group delete operation, orderings of application shutdown
and JSON-RPC are already unified.

Fixes github issue #218.
This patch introduces spdk_cpuset object to store and manipulate
the set of individual CPUs. The main objective of this object is
to replace cpumask declared as uint64_t and extend the limitation
of supported CPUs (lcores) above 64 CPUs.
spdk_cpuset is always allocated dynamically and accessed by opaque
pointer, what makes it easier to extend in the future without
breaking API/ABI.
This patch also extends parsing function allowing to set cpumask
using a list of cpus e.g. "[0-4,10,12]" sets mask of 0,1,2,3,4,10,12
as well as hexadecimal string with and without "0x" prefix.

virtio limits number of segments to 128, but this
2MB splitting could introduce additional segment

When there are two bdevs built on the same io_device,
it is possible that one bdev entirely saturates
underlying queue, not letting the second bdev issue
a single I/O. The second bdev will silently fail any
subsequent I/O and append it to the nomem_io list.
However, since we resend I/O only from I/O completion
callback and there's no outstanding I/O for that bdev
(io_outstanding==0), the I/O will never be resent.
It'll be stuck in nomem_io forever.
This patch makes nomem_io list to be shared between
bdevs built on the same device. It is now possible
that I/O completion callback from one bdev will retry
sending I/O from other bdev.
The shared bdev data is based on thread-local
bdev_mgmt_channel, so doesn't need any external
synchronization.

bdev hotremove event is send directly to hotremove callback given
during spdk_scsi_dev_construct() call. So any bdev hotremove might be
promoted to whole SCSI device removal (like in vhost) wich will trigger
LUN removal. But after returning from hotremove callback LUN and device
might be still referenced (eg to register poller or by outstanding IO).
Even worse: spdk_scsi_dev object is not dynamicaly allocated but
returned from static array which mean there is no way to detect
use-after-free error on spdk_scsi_dev by any tool. This might lead to
using SCSI device that is freed or assigned to different device.
To fix this:
- always delete LUN using hotremove path
- defer spdk_scsi_dev delete/removal after all LUNS are really
deleted.

This requires exposing struct spdk_io_channel in the
public header - mark it as internal with Doxygen
comments to make it extra clear that applications
should not use the data structure directly.
This is a very hot function in the main I/O path,
so making this function inline has a significant
performance benefit. A bdevperf microbenchmark
using null bdevs shows a 11% improvement.

Netmasks with 0 bits of prefix do not make sense. For example,
192.168.1.2/0 would allow hosts from any address, but this is
indicated with a special "ANY" value rather than a normal netmask.
Netmask prefixes of the full address size (e.g. 32 for IPv4 and 128 for
IPv6) are still allowed, since this represents a valid configuration
that matches a single specific address.
This also allows the IPv4 netmask math to be done entirely in uint32_t
instead of promoting to unsigned long long to avoid undefined behavior
when bits == 0 (shift count would have been 32 in that case).

The latest change for the portal group is applied to the vhost.
The following comment is quoted from it.
Currently the cpumask must be a subset of the reactor mask.
However, this is different from sched_setaffinity() function
and taskset command of FreeBSD and Linux. The latter will
be familier for more people. Hence the later is adopted.
The following is quoted from the FreeBSD Man Page of taskset:
The CPU affinity is represented as a bitmask, with the lowest
order bit corresponding to the first logical CPU and the
highest order bit corresponding to the last logical CPU.
Not all CPUs may exist on a given system but a mask may specify
more CPUs than are present.
A retrieved mask will reflect only the bits that correspond to
CPUs physically on the system.
If an invalid mask is given (i.e., one that corresponds to no
valid CPUs on the current system) an error is returned.
The masks are typically given in hexadecimal.

Moving forward, the spdk_blob returned to users will
actually be an I/O channel - not the blob structure
itself. So rename the existing spdk_blob to spdk_blob_data.
spdk_blob_data will continue to contain global state for
the blob. In the future spdk_blob will point to an
I/O channel for the blob - for now it effectively still
points to the spdk_blob_data, but by changing the
structure names here it will reduce the code churn in
future patches.

that lun->tasks should be empty. But for the exceptional case,
we may still need to handle those active tasks, to make
the scsi related application continue running instead of quit.
We should not directly call spdk_scsi_lun_complete_task since
those tasks are already sent to bdev layer. And finally, those
tasks will be return (even aborted) by call backs. So we only need to
set task status to condition, but
not call spdk_scsi_lun_complete_task directly.

Similar flags will be added at the blobstore level in a future
patch.
This allows backwards compatibility - i.e. allow older blobstore
applications to open blobstores created by newer blobstore
applications with new features. Any blob's using a new feature
should have an associated flag set in one of three new flag masks:
- invalid: if a bit is set in this mask that the application is not
aware of, do not allow the blob to be opened
- data_ro: if a bit is set in this mask that the application is not
aware of, allow the blob to be opened, but do not allow
write I/O nor any operation that changes metadata
- md_ro: if a bit is set in this mask that the application is not
aware of, allow the blob to be opened for performing any
kind of I/O, but do not allow any operation that changes
metadata
While here, bump SPDK_BS_VERSION to 3. We intend this to be the
last change made to SPDK_BS_VERSION - future versioning will be
done via blobstore or per-blob feature flags instead.

spdk_pci_device_claim() can be used to ensure only one process
at a time uses any given PCI device. Previously this was only
used in the bdev_nvme driver - other apps like nvme/perf do
not use spdk_pci_device_claim() and could effectively rip out
the device from a running bdev-based app like the NVMe-oF target.
So instead of modifying all of the nvme apps, put this logic into
the core nvme driver instead so that all applications get the
benefit transparently. Save the fd when the controller is constructed
and then close it when the controller is destructed to handle the
detach (including hotplug) cases.

Currently exposed API allows to load/unload and to
initialize blobstore on a device.
A spdk_bs_destroy() call is added in order to reach
functional parity with spdk_bs_init(). It was not
possible to remove blobstore from device from within
SPDK previously.
spdk_bs_destroy() takes blobstore pointer as argument
(instead of bs_dev), because blobstore has to be already
loaded to destroy it.

if the system crushed, we have no chance to sync the used md bitmap and

Some future patches will require specifying an lvol_store
name when calling spdk_lvs_init(). This means that passing
NULL for spdk_lvs_opts will no longer be an option. So
add an spdk_lvs_opts_init() (similar to spdk_bs_opts_init)
which will initialize a default value for the cluster size.
While here, prepend an underscore to spdk_setup_lvs_opts, since
this function is not part of the public SPDK API.

With this new API, callers can attach one specific ctrlr identified by

to multiple controllers, it is still suggested to use spdk_nvme_probe()
and filter the requested controllers with the probe callback.
Two primary use cases:
1) connecting to the NVMe-oF discovery controller
2) more straightforward way to connect a specific controller (avoiding
the probe callback)
A typical usage of this API with specific ctrlr_opts:
1. struct spdk_nvme_ctrlr_opts user_opts = {}
2. Call spdk_nvme_ctrlr_get_default_ctrlr_opts(&user_opts, sizeof(user_opts))
3. Modify the content of the initialized user_opts with user required value like
user_opts.num_io_queues = 8
4. Call spdk_nvme_connect(&trid, &user_opts, sizeof(user_opts))

At very high queue depths, bdev modules may not have enough
internal resources to track all of the incoming I/O. For example,
we allocate a finite number of nvme_request objects per allocated
queue pair. Currently if these resources are exhausted, the
bdev module will return failure (with no indication why) which
gets propagated all the way back to the application.
So instead, add SPDK_BDEV_IO_STATUS_NOMEM to allow bdev modules
to indicate this type of failure. Also add handling for this
status type in the generic bdev layer, involving queuing these
I/O for later retry after other I/O on the failing channel have
completed.
This does place an expectation on the bdev module that these
internal resources are allocated per io_channel. Otherwise we
cannot guarantee forward progress solely on reception of
completions. For example, without this guarantee, a bdev
module could theoretically return ENOMEM even if there were
no I/O oustanding for that io_channel. nvme, aio, rbd,
virtio and null drivers comply with this expectation already.
malloc only complies though when not using copy offload.
This patch will fix malloc w/ copy engine to at least
return ENOMEM when no copy descriptors are available. If the
condition above occurs, I/O waiting for resources will get
failed as part of a subsequent reset which matches the
behavior it has today.

tries to do something too quickly bad things happen.
To avoid application changes with how the g_devlist_mutex is
held, it is no longer held while calling
_spdk_io_device_attempt_free() because the app unload CB is
called from that function and may want to call
spdk_io_device_unregister() from its unload CB. So the lock
is now held and releases strictly around the list its
protecting which allows the CB from _spdk_io_device_attempt_free()
to be called without issue.

Previously, we naively assumed that a completed
reset was the reset in progress, and would
unilaterally set reset_in_progres to false.
So change reset_in_progress to a bdev_io pointer
instead. If this is not NULL, a reset is not in
progress. Then when a reset completes, we only
set the reset_in_progress pointer to NULL if we
are completing the reset that is in progress.
We also were not aborting queued resets when
destroying a channel so that is fixed here too.
The added unit test covers both fixes above - it will
submit two resets on a different channels, then destroy
the second channel. This will abort the second reset
and check that the bdev still sees the first reset as in
progress.

Upper layers are not supposed to put an I/O channel if there
are still I/O outstanding. This should apply to resets as well.
To better detect this case, do not remove the reset from
the channel's queued_reset list until it is ready to be
submitted to the bdev module. This ensures:
1) We can detect if a channel is put with a reset outstanding.
2) We do not access freed memory, when the channel is destroyed
before the reset message can submit the reset I/O.
3) Abort the queued reset if a channel is destroyed.

split, gpt and error all have a lot of similar code, and
are based on the presumption of one or more "partition" bdevs
on a "base" bdev. This results in quite a bit of duplicated
code between these three bdev modules. The error bdev
module does follow this same model - it just always has only
a one-to-one mapping between the error bdev and its base bdev.
As all of the modules move to allocating their own bdev_io
rather than allowing for adjusting an existing bdev_io and
resubmitting it, there will be even more duplicated code
between these modules.
So this patch adds a set of helper functions in the common
bdev library to eliminate all of this duplicated code.
This patch also moves the split module to use it - future
patches will also convert gpt and error.
