6368d6c0f5 nvme: add new spdk_nvme_connect() API to directly attach the ctrlr
With this new API, callers can attach one specific ctrlr identified by
the transport ID directly along with optional ctrlr opts. If connecting
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))

dc2fb2ed39 nvme: add a public API to rename spdk_nvme_ctrlr_opts_set_defaults
This change is relating to add a new public API spdk_nvme_connect() under
include/spdk/nvme.h. This new spdk_nvme_connect() API will connect the user
specified trid and have a user optional ctlr opts. Rename this API and make
it as public.

A typical usage of this API as following:
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

5fb8722899 bdev: add callback to free part_base
This puts responsibility on the caller to free the buffer
and do any other cleanup associated with the partition base
(for example, GPT buffer).

While here, also clean up a bunch of places where on
various failures during initialization, it would just
free the buffer instead of calling spdk_bdev_part_base_free().
The latter is required to make sure the bdev descriptor
gets closed as well.

94bc8cfdba bdev: add ENOMEM handling
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.

1e33a802b4 iscsi: fix layout of logout request reason field
The Logout Request reason field is the low 7 bits of byte byte 1; the
last bit of byte 1 is specified to be always 1, and we shouldn't
consider it to be part of the reason field.

The existing debug print code was parsing the reason field correctly (by
masking it against 0x7f), but it's simpler to just make the reason field
into a bitfield of the proper size; this fixes the real bug in the
reqh->reason != 0 check, which did not use the 0x7f mask.

Fixes GitHub issue #198.

1f935c7a9b bdev: properly handle aborted resets
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.

ab29d2ce5d bdev: improve handling of channel deletion with queued resets
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.

70a0bc3096 bdev: add bdev_io optimizations
First, improve packing of spdk_bdev_io.  Move any
fields which must be zeroed into the first cacheline.
Also change type and status from enums (needing 4 bytes)
to int16_t which is still a far bigger range than
needed.

Next, modify spdk_bdev_get_io to only zero the
first cacheline (actually a bit less).

SPDK_BDEV_IO_TYPE_INVALID is also added, making it
explicit that 0 is an invalid value for the IO type.
Previously this was somewhat inferred.

There are still additional improvements that can
be made to this area - primarily combining
spdk_bdev_get_io() and spdk_bdev_io_init() into
a single function.

85cc223946 bdev: add common partition helper functions
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.

e3971c41ea nvme_spec: update Identify Controller SGLS field
In NVMe 1.3, the Identify Controller data SGLS field's definition was
changed; in NVMe 1.2, the first bit simply indicated whether SGLs were
supported, but in NVMe 1.3, the first two bits now indicate whether SGLs
are supported and whether they require Dword-aligned data.

ca2931227e unit test: add new mock macro and use macros in nvme_ut.c
No new coverage added, just used the STUB macros in nvme UT
to make sure they cover all the cases and discovered a few small
tweaks needed: (1) added _V variant to declare void stubs (if
someone sees an easy way to make DECLARE_STUB handle this case
that'd be cleaner but I don't think its a big deal) and (2)
updated DECLARE_STUB so that it can set a struct return value
by adding {} to the ut_ variable set statement.

Also ordered the declarations simply for readability, the _V
first, the regular stubs next, the _P next and then the stubs
that don't have a macro to cover them because they do something
other than return a specific value.

a vbdev module is ready to claim the bdev for purposes
of creating virtual bdevs on top of it, it calls
spdk_vbdev_module_claim_bdev().  It can pass its
open descriptor as well to have it promoted to
write access (required for future vbdev modules like
logical volumes).

Note: error vbdev was changed to copy the base bdev
parameters one-by-one instead of a blind memcpy - we
do not want to copy the base bdev's vbdev_claim_module
into the new bdev!

Retire the old claim/unclaim semantics in favor of

This allows multiple clients to open a bdev,
