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.

valid data from last dirty shutdown. We will go through all the metadata pages
to find all valid data and rebuild them.

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.

29a33dab93 vhost: implemented indirect descriptors
Every descriptor may now contain
a separate descriptor table.

This increases the maximum number
of concurrent IO in a virtqueue
from about (vq->size / 3) to
(vq->size * SPDK_VHOST_IOVS_MAX).

Knowing that SPDK_VHOST_IOVS_MAX
is 128, and assuming that vq->size
is 128 (current hardcoded limit
for QEMU), this gives us over 16k
concurrent possible iovectors
on the fly

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.

721695e121 blob: fix issue with blobid handling
Fixes github issue #29.

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
