9872b99206 bdev: Avoid assert when read/write to bdev fails in _spdk_bdev_io_split
Currently when read/write to bdev fails in _spdk_bdev_io_split_with_payload
due to other than -ENOMEM, assert is called.

RAID bdev that utilizes the split IO feature is generally availale now
and it will be OK to remove this assert and return error instead.

0df515a842 bdev: Remove limitation of child iov size in bdev_io_split_with_payload()
When a bdev IO is split, if iovec size in a strip is more than 32,
the IO will fail.

Remove the limitation by spliting the split IO further.

369719c26b crypto: move PMD driver input validation to common function
Previously was only checking the crypto driver name in the conf
file parsing and not when it came in via RPC so a bogus name
could result in nasty stuff.  Moved the check to the common
function used by both paths so a bad name will fail gracefully.

Addresses github issue #444

cafd537c7d test: exercise crypto rpc calls
Most vbdevs have complete test suites that include rpc calls
to set them up and teare them down.  With crypto there's not
a lot to do w/test other than make sure it's configured and
run IO so right now that amounts to tools that use a config
(ini) file.  Adding create/delete calls here to get basic rpc
coverage in CI.

The fixes/udpates in the vbdev module and the .py files were
fixes found in enabling testing of the rpc calls.

1e4f9974a7 bdev: do not finish unitialized modules
To achieve its goal, this patch changes the order
in which bdev modules are finished. All modules
that examine bdevs (e.g. lvol,split,...) will be now
finished last. It should not cause any issues though,
since all bdevs are already removed at the time when
any module finish is called

Fixes #387

1d64773c2a raid: enable by default
We kept this disabled by default originally because it lacked
multiple iov support needed for vhost and nvmf in-capsule data.
Now that support has been added, there is no reason to not
enable it automatically - it has no extra package dependencies,
so requiring users to specify --with-raid to configure is just
an extra unneeded step.

51606ed402 bdev: Add crypto virtual bdev module
Initial support for softare AESNI_MB DPDK driver only.

Have tested (both aesni and QAT seprately and concurrrently) on underlying NVMe devices
with bdevio and a bdevperf script that runs IOs from 512B to 128K each with Q depths from
1 to 512 in powers of 2 for 30 seconds each run.

QAT can be included in the code (but not makefile) and marked as experimental
until we are ready to test in CI.  It works well on 2 systems but is a big PITA to get
the hardware setup and configured for use with DPDK (IMHO).

3f578219be bdev/raid: Extract adding base bdevs from RPC and apply it to parse .INI config
Initialization of bdev modules don't have fixed ordering.
Hence both cases should succeed to create configured raid bdev
for .INI config file.

1. create raid bdev and then create base bdevs of it.
2. before creating raid bdev, create base bdevs of it.

To do this, factor out adding base bdevs to raid bdev
to a helper function raid_bdev_add_base_devices() first
and then apply it to construct_raid_bdev RPC and parse .INI
config file.

a3004632e2 bdev/raid: Change construct_raid_bdev RPC to be consistent to other bdev modules
Change the behavior of construct_raid_bdev RPC to be consistent with
other bdev modules.

Create a config of raid bdev first. Then create a raid bdev based
on the config.

If both succeed, the config and the raid bdev are not removed even if
any failure occur later in construct_raid_bdev RPC. Otherwise, both
are removed and return failure.

During iteration of adding base bdevs in construct_raid_bdev RPC,
- skip any nonexistent bdev and move to the next base bdev.
- if adding any base bdev fails, move to the next bdev.
- if adding base bdevs don't fail but any base bdev doesn't exist,
  the raid bdev is in the configuring state and return success.
- if adding base bdev fails, the raid bdev is in the configuring state
  and return failure.
- if all adding base bdevs succeed, configure the raid bdev. If configuring
  the raid bdev fails, move the raid bdev to the offline state and return
  failure. If configuring the raid bdev succeed, return success.

check_and_remove_raid_bdev() becomes unused in raid_bdev_rpc.c but
is still necessary in UT. Hence move this function to UT.

In UT, finding a raid bdev config by name becomes necessary. Hence
factor out the iteration to a function and use the function in UT.

de4d961996 bdev: set iovs on correct bdev_io in spdk_bdev_io_put_buf
spdk_bdev_io_put_buf() is responsible for reclaiming
bdev-allocated buffers from a bdev_io.  If there are
bdev_ios waiting for one of these buffers, it calls
spdk_bdev_io_set_buf() on the next bdev_io in the queue.
This will set the iov_base and iov_len on the bdev_io
to point to the bdev-allocated buffer.

But spdk_bdev_io_put_buf() was calling spdk_bdev_io_set_buf()
on the just completed bdev_io, not the next bdev_io in the
queue.  So fix that.

86d77e2eb6 bdev: account for missed qos timeslice timeouts
There could be cases (especially in virtualized and/or test
environments) where we could accumulate significant skew in
the timeslice frequency.  Rather than depend on the application
framework to try to guarantee the rate of timeslice poller
callbacks, keep track internally of the last time the poller
was invoked.  If/when we accumulate and detect skew equivalent
to one or more timeslices, increase the allowed IO and bandwidth
of the next timeslice to accomodate.

Since bdev poller now calls spdk_get_ticks() to do accounting,
this patch also fixes up the increment_time() unit test function
and the test env layer to properly increment the fake TSC.

set split_on_optimal_io_boundary = true.  This will ensure
that all I/O submitted to the raid module do not cross

This is a step towards removing the iovcnt == 1
limitation.  Further improvements and simplifications
will be made in future patches before removing this
restriction.

Unit tests need to be adjusted here to not span

1ac058ca08 bdev/raid: Set RAID bdev's name at its creation to prevent unnamed device
Next patch will keep RAID bdev without removal when adding any base
bdev to the RAID bdev fails for some reason for construct_raid_bdev
RPC.

The half-baked RAID bdev will become unnamed and this should be avoided.

4bd9762165 bdev: add split_on_optimal_io_boundary
A number of modules (RAID, logical volumes) have logical
"stripes" that require splitting an I/O into several
child I/O.  For example, on a RAID-0 with 128KB strip size,
an I/O that spans a 128KB boundary will require sending
one I/O for the portion that comes before the boundary to
one member disk, and another I/O for the portion that comes
after the boundary to another member disk.  Logical volumes
are similar - data is allocated in clusters, so an I/O that
spans a cluster boundary may need to be split since the
clusters may not be contiguous on disk.

Putting the splitting logic in the common bdev layer ensures
bdev module authors don't have to always do this themselves.
This is especially helpful for cases like splitting an I/O
described by many iovs - we can simplify this a lot by
handling it in the common bdev layer.

Note that currently we will only submit one child I/O
at a time.  This could be improved later to submit multiple
child I/O in parallel, but the complexity in the iov splitting
code also increases a lot.

Note: Some Intel NVMe SSDs have a similar characteristic.
We will not use this bdev stripe feature for NVMe though -
we want to primarily use the splitting functionality inside
of the NVMe driver itself to ensure it remains fully
functional.  Many SPDK users use the NVMe driver without
the bdev layer.

6fd1d004a8 vbdev: add get_buf call to passthru example
Previously a null buffer on read would get passed on which would
be fine for a simple example but for something more complex where
the module in question might need that buffer at some time after
the read callback, it's possible that an underlying module might
free it too soon.  So, to be a good example we now own the buffer
in this module.

5abf2ecfcd Do not recreate passthru vbdev unnecessarily.
The passthru module associates a vbdev and the underlying bdev.
This association lives throughout the lifetime of the module and because
of this, passthru vbdevs are recreated when they shouldn't be.

This patch ensures that the association between a vbdev and a bdev is
broken when the vbdev is removed, so that if the underlying bdev is ever
recreated (after being deleted), the vbdev does not reappear.

Note that this change does not affect hot-remove operations.

671b77e5cd bdev: remove vbdevs and base_bdevs arrays
The intents of these arrays was to keep track in the
bdev layer of all base<->virtual bdev relationships -
i.e. which member disk bdevs make up a RAID bdev,
which logical volume bdevs are associated with a
bdev that contains an lvolstore, etc.

Currently none of this is used however.  And trying
to keep track in the bdev layer instead of asking
the bdev modules for the relationships has a number
of complications.  Early one, we tried to do this
with TAILQs - but that doesn't work since this can't
be done with a single TAILQ_ENTRY in the bdev
structures.  So we moved to arrays - that works a bit
better, but then the pointer arrays have to be
realloc'd which isn't ideal.

The biggest problem though with these arrays is that
they held bdev pointers - not bdev descriptor pointers.
It's not really valid to access bdevs without a
descriptor - the descriptors are what make sure active
references are accounted for when a bdev is hotplugged.
Of course the bdev layer knows when a bdev is getting
removed and could go and do the updates to these
arrays separately - but that just seems very convoluted.

So for now just remove these arrays completely.  If
there is a future need for the bdev layer to
understand relationships between bdevs, we can add
module APIs so that the generic layer can ask
the modules about the relationships.

9ee4942130 bdev/gpt: fail more gracefully on extended block size bdevs
The GPT module isn't designed currently to support extended
block sizes like 520 or 4104, and we don't really have a good
way to put GPT down on one of these devices anyways.

So just check the block size when examining a new bdev, and
fail immediately if it's not an even multiple of 512.

Long-term, this should probably be a DEBUG print and not an
ERRLOG, but while we work through the bdev implications
of extended block sizes, keep it as an ERRLOG to facilitate
debugging.

c899854d03 bdev: add new fini_start notification callback for modules
When an SPDK application shuts down, the bdev layer will
automatically unregister all of the bdevs to ensure they
are properly quiesced and cleaned up.

Some modules may want to perform different operations when
a bdev is destructed during normal runtime vs. shutdown.
For example, for lvol, when the last lvol is cleaned up,
it should unload the lvolstore, release and close the bdev
that contains the lvolstore.  You never want to do this
during normal runtime though - it is perfectly valid to
have an lvolstore that contains no lvols.  RAID and future
bdev modules such as multipath have similar use cases.

So add a new bdev module callback named "fini_start".
If a module specifies a function pointer for this callback,
the bdev layer will call it before it starts the bdev
unregistrations.

This enables some future patches to the bdev layer such
that it will always unregister block devices that are not
claimed (i.e. logical volumes) before block devices that
are claimed (i.e. the bdev containing an lvolstore).

27635c770f bdev: track io_stats from deleted channels
Currently, the bdev layer iterates over all of the
existing channels of a bdev to collect I/O
statistics.  But this ignores statistics for
channels that are deleted.

Fix that by keeping an io_stat structure in the
bdev which accumulates statistics for deleted
channels.  Use the bdev mutex to protect these
accumulations.

b326e51219 bdev/virtio_blk: defer bdev destruct completion
Even after the bdev is removed, the underlying virtio
device may be still alive for some time. The user may
then try to recreate the virtio bdev and could technically
initialize a second simultaneous connection to a vhost
target. It does not cause any technical problems, but the
target may reject such connection if it reached a connection
cap or doesn't support more than one connection per target
(like SPDK vhost does as of today).

Since the fix is straightforward, here it is.

Note:
Virtio SCSI is already safe, because it uses a separate
completion callback to indicate virtio device destruction.

originally derived from that. Due to copy and paste,
some incorrect copyright attributions have been added
to other files that do  not derive from istgt, so
this patch removes those.

It is doubtful, at this point, that there is any code
whatsoever that remains from the original istgt, but
we can revisit that at a later time.

c60ae3c356 raid: get buffer on reads before sending child ios
For front-ends like iSCSI (and NVMe-oF in the future)
which want the backend to specify the data buffer, the
RAID module doesn't copy the pointer to the allocated
buffer from the child IO back to the parent IO.  It
really can't copy the pointer - the child IO owns it
and will free it.

So the RAID module needs to allocate the buffer first
and then pass it down.

A few words for the iscsi_logout_async call, which was

Destroying the iscsi context, which is done at bdev
destruction, will "tear down any existing connection"
as the libiscsi docs say, so there's apparently no
need to perform a manual logout.

e96a076b51 bdev/raid: fix the double free memory in realloc
Use free() instead of realloc() to free allocated memory.
Currently realloc() is used to free memory unintentionally. Hence
the pointer is not nullified and it has caused double free.
realloc(g_spdk_raid_config.raid_bdev_config, 0)
is equivalent to free(g_spdk_raid_config.raid_bdev_config).

Use Shuhei's patch https://review.gerrithub.io/#/c/spdk/spdk/+/420224/
as a reference.

Fixes GitHub issue #372.

For submit_td, sometimes, segfault is thrown because

to a invalid address. And assigning the submit_td in
bdev_iscsi_submit_request prevent this from happening.

9ddf643831 thread: don't immediately remove channel from list when put
When spdk_put_io_channel is called, if its the last reference,
we defer actual destruction of the channel, so that code
in the same context which may be referring to the channel
doesn't crash.

But it is possible that an io_channel for that same io_device
could be requested before the deferred message is processed.
This would result in a second io_channel being created for
that device on the same thread.

To avoid this case, don't immediately remove the channel from
the list when the last reference is put.  When the deferred
message is processed, if additional references were allocated
in the meantime, don't destroy the channel.

41586b0f1d bdev: add raid bdev module
Raid module:
============
- SPDK raid bdev module is a new bdev module which is
  responsible for striping various NVMe devices and expose the raid bdev
  to bdev layer which would enhance the performance and capacity.
- It can support theoretically 256 base devices (currently it is being
  tested max upto 8 base devices)
- Multiple strip sizes like 32KB, 64KB, 128KB, 256KB, 512KB etc is
  supported. Most of the current testing is focused on 64KB strip size.
- New RPC commands like "create raid bdev", "destroy raid bdev" and "get raid bdevs"
  are introduced to configure raid bdev dynamically in a running
SPDK system.
- Currently raid bdev configuration parameters are persisted in the
  current SPDK configuration file for across reboot support. DDF will be
introduced later.

High level testing done:
=======================
- Raid bdev is created with 8 base NVMe devices via configuration
  file and is exposed to initiator via existing methods. Initiator is
able to see a single NVMe namespace with capacity equal to sum of the
minimum capacities of 8 devices. Initiator was able to run raw
read/write workload, file system workload etc (tested with XFS file
system workload).
- Multiple raid bdevs are also created and exposed to initiator and
  tested with file system and other workloads for read/write IO.
- LVS / LVOL are created over raid bdev and exposed to initiator.
  Testing was done for raw read/write workloads and XFS file system
workloads.
- RPC testing is done where on the running SPDK system raid bdevs
  are created out of NVMe base devices. These raid bdevs (and LVOLs
over raid bdevs) are then exposed to initiator and IO workload was
tested for raw read/write and XFS file system workload.
- RPC testing is done for delete raid bdevs where all raid bdevs
  are deleted in running SPDK system.
- RPC testing is done for get raid bdevs where existing list of
  raid bdev names is printed (it can be all raid bdevs or only
online or only configuring or only offline).
- RPC testing is done where raid bdevs and underlying NVMe devices
  relationship was returned in JSON RPC commands
