We've had cases (especially with vhost) in the past where we have
a valid vaddr but the backing page was not assigned yet. DPDK used
to return 0 as the phys addr in these cases but now it returns
RTE_BAD_IOVA. Unfortunately we don't have any tests currently
in the test pool that hit this condition, but at least one user
has an environment which hits it and this patch fixes their
problem.
Make sure we still work with older versions of DPDK as well.
Fixes issue #260.

This patch selects part of commit:

In the previous patch, the failed reason is the logic
that admin qpair actively destroys the ioqpair when
the admin qpair is recevied early. For this part,
we need to investigate it later since for multiple core
usage in our current handling case, we possibly have
admin qpair firstly to enter the destruct phase even if
the initiator sends the I/O qpair deletion first. Thus,
the ioqpair deletion can be recycled twice.
And this patch is selecting the part of the logic:
only to make each ioqpair recycled by its own thread.

Nevertheless, this extra check should be here to protect

a ring with least N+1 size. That's because rte_rings
need one extra empty element to differentiate between
the full and empty state. To make it worse, the ring
size has to be a power of two, so rte_mempools use
`rte_align32pow2(mp->size + 1)` for the size calculation.
And rte_ring memory has to be physically contiguous.
Allocating a mempool of capacity 262144 requires at
least (2 * 262144) * sizeof(void *) = 4MB memory. This
made us require at least 2 physically contiguous
2MB hugepages.

This is the first step toward fixing the behavior of the lvol bdev
module so that it handles spdk_bdev_unregister() correctly.
Currently, when an lvol bdev is unregistered, this causes the associated
lvol to be deleted; this isn't the desired behavior, since
spdk_bdev_unregister() is just meant to drop the currently-exposed bdev,
as in a hot-unplug event, not destroy the backing storage.
The current implementation of the new destroy_lvol_bdev method still
calls into the exsting (broken) spdk_bdev_unregister() path, but this at
least lets us fix the existing delete_bdev RPC callers that really
intended to destroy the lvol.
The next step is to make vbdev_lvol_destroy() call spdk_lvol_destroy()
instead of unregistering the bdev, which will require cleanup in the
generic lvol layer to remove the close_only flag.

This commit provides an API to obtain an information about
snapshot and clone relations.
The main objective is:
1) Determinate if we can delete snapshot (if have some created
clones),
2) Provide an information about parent/children nodes to the upper
layer (e.g. lvol)
Realization:
1) Structure parent-children is stored in the blob store object
and updated on:
a) blob store load,
b) blob create/delete,
2) Full information about parent-children is provided via new API:
spdk_blob_get_parent() and spdk_blob_get_children(),
Note:
While we don't store an information about these relations in the
blob store, we need to open all blobs on blob store load to create
it. It should be considered that it have an impact on the blobstore
loading performance.

Recently added a new call to bdev modules to inform them of when
bdev subsystem init is complete. The intention is for modules like
RAID or crypto that need to take some action after the initial bdev
subsystem init such as 'build whatever RAID volumes you can, all
initial examine callbacks are done' or in the case of crypto 'OK,
construct all of your crypto structures for HW and SW PMDs and
associate each to configured vbdevs.'
Now that I've implemented the crypto case I see that the call was
misplaced and will execute following any examine_done call including
subsequent bdev registrations. Those cases, for both RAID and crypto,
need to follow a different path (examine) since all of the activities
associated with the new init_complete() callback are intended just for
the very first initialization of SPDK.
So, long story short, moving this call so that it's only executed once
when subsystem init is done and not on subsequent bdev registrations.

Imagine the following code flow:
1. `spdk_put_io_channel();`
2. `spdk_io_device_unregister();`
Since putting an io_channel is always deferred,
it is likely that spdk_io_device_unregister will
lock the io_channel mutex first. It will set
dev->unregistered flag and then quickly realize
there are still open channels for this device
(refcnt > 0) - so it'll return. All fine here.
However, if the deferred put_io_channel happens to
lock the mutex first from other thread, it will
decrement the refcnt and attempt to free the device.
Both the decrementation and freeing are done under
a mutex, but there is a slight window inbetween
where the mutex is re-locked. spdk_io_device_unregister
is already sleeping on a mutex_lock(), so it might
strike now. It'll see there are no more io_channels
for this device and free the device. Once
put_io_channels regains the lock again, it will attempt
freeing the device for a second time.
This patch removes the slight window mentioned above.

When testing whether QoS is enabled, the code previously
checked mutable values in the bdev itself. Instead, it needs
to check the flag in the channel.
Right now, QoS can only be configured statically when the
bdev is created. This means that no channels will exist
prior to QoS being turned on, which simplifies setting
the per-channel flag (only need to set it when a channel
is created).

Reason: Initiator sends the qpair deletion in wrong order.
The correct order should be all io qpairs deletion and then
the admin qpair deletion. However, nvme perf does not follow
this since we did not catch ctrlr + c. If we catch ctrlr + c,
we need to use the spdk app framework, or other methods. We should
support this in another patch.
Morever, to prevent the incorrect behavior causing the coredump
of target, we need also consider such case in our NVMe-oF target
design. And this patch, can solve this issue, it will defer the
admin qpair deletion when there are still active io qpairs.

As of glibc version 2.3.4 onwards getpid() is no longer cached. SPDK
makes calls to it in nvme_allocate_request() which is called for each
nvme request received. This results in a system calls up to millions of
times per second which slows down nvme submissions. Since the pid never
changes, it only needs to be called once in initialization per process.
This improves the performance of nvme_allocate_request() signficantly.

Instead of silently truncating overly-long SCSI dev names, add an
explicit check and return an error if the name is too long.
Since we now calculate the length of name up front, this also allows
simplification of the copy into dev->name.
This also ensures that dev->name will always be zero-terminated, so we
can simplify the strnlen() in spdk_bdev_scsi_pad_scsi_name() to a
strlen() and remove the invalid unit test case for padding names longer
than SPDK_SCSI_DEV_MAX_NAME.

Due to the check on line 153 in t_nvme_dev, Klocwork
thinks nvme can be null. Therefore, we must check that
it isn't null before dereferencing it. We can either
solve this the way I have here, or remove check
that causes to_nvme_dev to return null.

In this case, assign the memory address of the allcoated

g_virtio_driver contained just a list of all
Virtio-SCSI devices. It's now being removed for
two reasons:
* it's backend-specific, doesn't fit a generic virtio lib
* it's difficult to ensure thread-safety for it
Virtio bdev modules will now manage their Virtio
devices by themselves. Virtio-SCSI has now an internal
device list. (And VirtioBlk module maps devices to
bdevs 1:1, so doesn't need any additional work here.)

ImmediateData in negotation parameters can be controlled by the config
file and currently "Yes" or "No" are valid values of it in the config
file. "Yes" or "No" means almost bool. Additionally, ImmediateData is
defined as boolean value in the iSCSI specification as follows.
However ImmediateData is an uint32_t variable and 0 or 1 are used in
SPDK now.
In the upcoming JSON config file, boolean value should be set to
ImmediateData.
Hence change all variables and constants related with ImmediateData
to boolean in this patch.
InitialR2T, DataPDUInOrder, and DataSequenceInOrder are not controllable
by the config file but these are defined as boolean value in the
iSCSI specification.
Hence change them to bool too.
Besides, AllowDuplicateIsid is used almost as boolean value. Hence
change it to bool too.
InitialR2T=<boolean-value>
ImmediateData=<boolean-value>
DataPDUInOrder=<boolean-value>
DataSequenceInOrder=<boolean-value>

A net implementation should be allowed to not create a socket group.
It would basically mean that it is not participating in polling at all.
This came up during VPP integration. To enable using both types of sockets,
all types are polled within socket group. There is possibility of VPP
not being initalized at all (VPP process not running or failing connecting).
This would result in hard requirement of VPP always running when its
support is compiled into SPDK. Handling NULL here allows VPP to opt-out of
this polling.

Portal, portal group, initiator group, and target node don't use fixed size
array anymore. To use the same naming rule in iSCSI subsystem and in SPDK
is helpful to understand and maintain. Current naming rule is not bad but
to use unified and compact name is prioritized at this time.
This patch changes function names as follows:
- spdk_iscsi_init_tgt_nodes() -> spdk_iscsi_parse_tgt_nodes()
- spdk_cf_add_iscsi_tgt_node() -> spdk_iscsi_parse_tgt_node()
- spdk_iscsi_portal_grp_array_create() -> spdk_iscsi_parse_portal_grps()
- spdk_iscsi_portal_grp_create_from_configfile() -> spdk_iscsi_parse_portal_grp()
- spdk_iscsi_portal_create_from_configline() -> spdk_iscsi_parse_portal()
- spdk_iscsi_portal_grp_array_destroy() -> spdk_iscsi_portal_grps_destroy()
- spdk_iscsi_init_grp_array_create() -> spdk_iscsi_parse_init_grps()
- spdk_iscsi_init_grp_create_from_configfile() -> spdk_iscsi_parse_init_grp()
- spdk_iscsi_init_grp_array_destroy() -> spdk_iscsi_init_grps_destroy()
For example "parse" is already used to explain the operation in portal_grp.c.
Hence using "parse" is familiar and not strange in iSCSI.

This patch is to add the basic support of QoS on bdev.
Including two major functionalities:
1. The QoS rate limiting algorithm:
a. New IO will be always queued first also under
the no memory condition
b. Start the QoS IO operation based on the limit
c. A poller started in each millisecond to reset
the rate limit and send new IOs down
d. The rate limit is based on the millisecond and
converted from user configurable IOsPerSecond
2. The Master Thread management:
a. Add a per bdev channel_count
b. Whenever QoS is enabled on bdev, if QoS bdev
channel is not created, create the QoS bdev
channel and assign the QoS thread
c. When new IOs coming from different channels
(threads), pass the IOs to the QoS bdev channel
through the thread event
d. When the IOs are completed from the QoS bdev
channel, pass the IOs back to its orignal
channel(thread)
e. Destroy the QoS bdev channel when it is the
last bdev channel for this bdev. Defer the
destruction if current thread is not QoS thread

Currently SPDK_BDEV_MODULE_REGISTER() take many parameters. Extending it
(eg for incoming JSON configuration dump/load) is quite challenging and
error prone. As we are already here in next patches, rework this macro
to take one parameter - the pointer to struct spdk_bdev_module_if.
This patch also remove following macros:
SPDK_GET_BDEV_MODULE - this is not really needed, to find module outside
module translation unit use spdk_bdev_module_list_find()
SPDK_BDEV_MODULE_ASYNC_INIT and SPDK_BDEV_MODULE_ASYNC_FINI - replaced
by bool fields in spdk_bdev_module_if struct.

There was some thinking that we would need to allocate
I/O channels on a per-blob basis to handle dynamic
resizing during I/O. Making spdk_blob an opaque handle,
with the existing spdk_blob structure renamed to
spdk_blob_data was a first step towards making that
happen. But more recent work on blobstore has
simplified the resizing approach, so this spdk_blob_data
is no longer needed. So revert it.

Many bdev modules create their own bdev structure
with spdk_bdev as the first member. bdev.c currently
uses the spdk_bdev pointer as its io_device handle,
forcing bdev modules to pick something different.
Change this to use the spdk_bdev pointer + 1 bytes
as its io_device handle. The actual handle does not
really matter - it just needs to be unique. This will
simplify bdev module development.

In early days of SPDK, there was an experimental userspace
TCP stack called libuns. The SPDK iSCSI target supported
using either the default POSIX/kernel TCP stack or this
libuns TCP stack.
libuns is no longer in use, but work has started on
supporting the FD.io VPP TCP userspace stack. Abstractions
are being put in place to allow *both* the POSIX and VPP
stacks simultaneously.
So remove the concept of a "default" net_framework that is
defined with weak symbols that can be overridden by another
object file. While here, also remove the "clear_socket_association"
concept which was specific to libuns.

This doesn't really fix anything as rte_vhost
logging functions are extremely poorly designed
and do smp_wmb() by themselves - but only if
logging is enabled...
Let's move the barrier in our vhost.c. This
doesn't change any behavior, but makes the code
more readable. It surely looked weird to update
the ring, log it, and then do smp_wmb().

This feature is not particularly useful for storage.
It forces us to read additional vq memory on each
I/O completion and that's quite expensive.
Quoting VIRTIO 1.0:
```
VIRTIO_F_NOTIFY_ON_EMPTY (24)
If this feature has been negotiated by driver, the device MUST issue an
interrupt if the device runs out of available descriptors on a
virtqueue, even though interrupts are suppressed using the
VIRTQ_AVAIL_F_NO_INTERRUPT flag or the used_event field.
```
Later on:
```
Note: An example of a driver using this feature is the legacy networking
driver: it doesn’t need to know every time a packet is transmitted, but
it does need to free the transmitted packets a finite time after they
are transmitted. It can avoid using a timer if the device interrupts it
when all the packets are transmitted.

While here, remove old epoll/kqueue code in iscsi/conn.c that
was commented out when the iSCSI idle connection code was
recently removed - we now have a real implementation of it
in sock.c so the original code is no longer needed as a

Orderings of portal group create operation are diferrent between

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

For thin provisioned blobs we allocate dma memory
required for copying cluster from backing device.
When cluster size is too big dma allocation may fail
silently (only IO error).
Use PRIu32 to print out the cluster size, and while
here, fix two other places that were using %d to print
cluster size instead of PRIu32.

The spdk_json_decode_array() function previously tried to check whether
the array would fit into the provided number of output elements
(max_size) before decoding; however, the check was incorrectly comparing
the total number of nested JSON values in the array rather than just the
count of top-level array elements.
Rather than doing the check up front (which can't be done without
modifying the way array lengths are stored in spdk_json_value), just
check if we have reached the end of the 'out' array on each iteration of
the decoding loop.
Fixes GitHub issue #232.
