e68e2e749b lvol: do not unload/destroy lvs when operation on lvol is pending
There is a scenario where we can try do unload or remove
lvol store while lvol present on that lvol store is being
closed or destroyed.

Scenario:
1. send delete_bdev rpc command
2. command returns before lvol is actually closed/destroyed
   (does not wait for callback)
3. send destroy_lvol_store rpc command
4. lvs is destroyed before lvol is destroyed
5. lvol destroy callback is called on destroeyd lvol store

Aboive scenario can be reproduced using:
spdk/test/vhost/spdk_vhost.sh --integrity-lvol-scsi

2baeea7dd4 bdev: add callback to spdk bdev unregister and bdev destruct
Currently deleting bdev does not support asynchronous delete
operations. Because of that results are returned before device
is actually deleted and some operation can be peformed on that
device after removal of this device started.

e6d053e78a lvol: add lvol unique name
Add a name to each lvol which is persisted as a blob
xattr.  lvol names must be unique within its
lvolstore.

While here, fix a few lvol_ut issues that were caught
as part of testing the lvol unique names.  Also fix
a couple of tests that registered the wrong string
name with CUnit.

c6f1d12930 lvol: move name to old_name
There are some upcoming changes which will deprecate
the old lvsuuid_blobid name in favor of an
lvs_name/lvol_name name where these names are
user-specified.

In preparation for this change, rename the previous
lvol->name to lvol->old_name.  This will allow us
to add a new lvol->name but keep the original
old_name during the transition.

08ac0074ce lvol: add unique lvolstore name
Each lvolstore now has a unique name which is persisted to
metadata.  Eventually this will provide a friendlier
way to reference logical volumes, in the form
lvolstore_name/lvol_name.

This patch only covers the unique lvolstore name.  An
lvolstore may not be created nor loaded if its name
conflicts with an already loaded blobstore.

Currently there is no way to rename an lvolstore to
resolve a conflict.  This will be coming in the future.

70e25b39ac lvol: refactor unit tests
Create blob_store and blob placeholders, to mimic what a real
SPDK blobstore would do.  Then we can set different status
values on the blobstore and blobs to return different status
instead of just a single global variable for injecting different
status values.

This is also needed for future tests where we need to have
multiple lvolstores at once to test name collisions.

3f9cbe513b blob: add write_zeroes support
Unmap does not guarantee that erased blocks will return all zeroes.
using write_zeroes when unmapping metadata gives the
desired behavior for a blob.

Only metadata pages will be cleared with write_zeroes in this patch;
blob data clusters will still call unmap.  This behavior may be made
configurable in a later patch (to allow the user to request zeroing of
clusters rather than just unmapping).

2df9f03c47 blobstore: New API call to destroy blobstore [1/3]
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.

f97c8b3142 lvol: add spdk_lvs_opts_init()
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.

This increases the maximum number

Knowing that SPDK_VHOST_IOVS_MAX

for QEMU), this gives us over 16k
concurrent possible iovectors

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))

36a8f75006 scsi: fix LUN 0 check in scsi_dev_construct
When constructing a SCSI device, LUN 0 must be assigned to some LUN.
However, the current code was assuming that LUN 0 had to be in the first
array element of lun_id_list in spdk_scsi_dev_construct().  Combined
with the scripts/rpc.py implementation that uses a Python (unordered)
dictionary object to generate the lun_ids array, there could be cases
where LUN 0 exists in the list but isn't first.

Fix the check by allowing LUN 0 in any position of the lun_id_list
array.

Because of how we handle the blobid and pagenum in blobstore,
it was possible to have blobstore inadvertently open the wrong
blob if open is provided a blobid where the lower 32 bits match
an existing blob but the upper 32 are clear.

Patch does the following:
- removes assert() that caught this on MD load and replace with
an error given that this condition can be induced via the API
- cleanup of pagenum and blobid conversion/handling to make it
clearer how they're related and converted
- new UTs that would have failed w/o the new check in place

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.

b51b8b4f9c lvol: fix incorrect assumption of 1MiB cluster_size
Previously incorrectly it was assumed that cluster size
was always to be 1MiB. For most evident example of this
please see spdk_lvol_create() sz > free_clusters comparison.

This is now fixed and lvol->sz was changed to lvol->cluster_num.
It was done to increase readability - only dealing with
number of clusters when creating or resizing lvol.

130d278adf blob: defer calling unload callback until dev is destroyed
Fixes condition where blobstore was prematurely calling the
application callback on spdk_bs_unload(), if the application
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.

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.

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.

e87808c4fb blobstore: sync super block after set the "clean" as 0.
The system could crash anytime, we need sync the "clean" flag
into disk as soon as we load the blobstore. Then if the system crashed,
we will find the blobstore is not clean shutdown next time when we load
the blobstore, and we could run the recover process then.

1d304bc5d8 nvmf: Rename spdk_nvmf_conn to spdk_nvmf_qpair
Match the terminology used in the NVMe-oF specification,
which is queue pair. For the RDMA transport, this maps to
an RDMA queue pair, but may map to other things for other
transports. It still is logically a "connection" from
a networking sense.

03788f93df nvmf: Rename spdk_nvmf_session to spdk_nvmf_ctrlr
This is just a rename - the functionality hasn't changed.
Use the same terminology as the specification (which is controller)
so those familiar with the specification can more easily
approach the code base.

This is still conceptually equivalent to a "session" in the
networking sense.

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.

vbdev modules still open/close bdevs as normal, but
should open bdevs read only when tasting (i.e. reading
the GPT to see if there are SPDK partitions).  When
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!

so its type is not important. (We can cast it later if we add support

vbdev modules can use to notify the generic bdev layer
once a base bdev examination is complete.

This is especially required for asynchronous vbdevs
like GPT which must issue I/O to the base bdev.

As part of this patch, add examine callbacks
for both split and error, which for now only call
this new functions.  Later patches will move code from
the init callback to the examine callback for these
modules.  examine callbacks are now required for all
vbdev modules.

35d46267b8 jsonrpc: remove support for batch requests
This will greatly simplify the implementation of asynchronous requests,
and asynchronous requests also allow clients to submit multiple
overlapped requests, making batches unnecessary for executing multiple
RPCs at once.  Additionally, our RPC client (scripts/rpc.py) does not
use batch requests.

57d174ff67 bdev: add spdk_bdev_open/close
Retire the old claim/unclaim semantics in favor of
open/close.  Clients must now open a bdev to get
an spdk_bdev_desc, then pass this desc to get an
I/O channel.

This allows multiple clients to open a bdev,
although only one may open a bdev with write
access.
