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
   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

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.

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.

674c709733 test/bdev: add simulated multi-thread unit tests
Use the mock wrappers to override pthread_self(), enabling
the unit tests to switch emulation between different threads
from the context of a single unit test threads.

These tests don't do anything useful yet, but will get
fleshed out more as part of some upcoming changes that
will require some more rigorous testing for multi-thread
scenarios (such as multiple channels).

the report is valid - it's possible that with the additional

That function could be called from outside of the vhost reactor,
causing data races and possible segfaults.

Now, after this patch, all ctrlr-changing functions take spdk_vhost_dev
parameter, meaning they should be called via external event API [1],
which soon will be the only way of obtaining spdk_vhost_dev pointer.
