e42bb743f9 crypto: Misc cleanup from final review
* fixed typo in comment
* cleanup up some current_len logic that was no longer needed
after changing to LBA as IV
* moved a few src_mbufs assignments so they are grouped together
for easier reading
* updated vbdev_crypto_io_type_supported() to positively decode
supported IO types
* updated vbdev_crypto_dump_info_json() to use json _named_* API

Re-tested with overnight bdevperf OIO 1...256 sizes 512..65536
as well as bdevio and fio (basic multi-threaded tests)

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).

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.

01e7c02e15 bdev: call spdk_bdev_io_get_buf before splitting
We cannot split an iov if a buffer hasn't been
allocated yet.  So always call spdk_bdev_io_get_buf
on reads before trying to split.

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.

f118de60af bdev: fix race condition between spdk_bdev_close and _remove_notify
When new bdev was created, the struct spdk_bdev_module::examine_disk()
may open and close bdev. On the other hand, if something goes wrong,
the creation procedure may unregister new created bdev, so race
condition appeared between _remove_notify() and spdk_bdev_close().

Add the new field "closed" and "remove_notified" in struct spdk_bdev_desc,
so _remove_notify() and spdk_bdev_close() knows how to deal with this
situation.

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.

that all I/O submitted to the raid module do not cross

This is a step towards removing the iovcnt == 1

restriction.

When raid_bdev_alloc_base_bdev_resource() is called through raid_bdev_examine(),
if raid_bdev_alloc_base_bdev_resource() fails, raid_bdev_cleanup() is called
without freeing base bdev resource.

There is no way to free base bdev resource in this case.

Hence remove cleanup call.

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.

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.

43c8d0eb1e bdev/split: use bdev_part interface to get split names
The base_bdev and vbdevs arrays are going away in the
common bdev layer in a future patch, so prepare for that
in the split RPCs to use the bdev_part interface instead
to get the names of the split bdevs created from the
base_bdev.

No change in observed functionality.

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).

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.

a1ec258ac7 Clean up some incorrect Copyright statements
Daisuke Aoyama originally contributed to istgt, the
iSCSI target in FreeBSD. The SPDK iSCSI code is
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
never possibly called, but is now completely removed:
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.

4219407a93 lvol: destroy_lvol_bdev implementation
This patch fixes lvol delete behaviour.
First, we look if there are any dependencies that disallow lvol deletion.
If there are any (i.e. dependent clones) we fail.
Otherwise we delete lvol and unregister associated bdev.

destroy_bdev no longer deletes lvol.

For submit_td, sometimes, segfault is thrown because
in bdev_iscsi_io_complete the iscsi_io->submit_td points
to a invalid address. And assigning the submit_td in
bdev_iscsi_submit_request prevent this from happening.
Already tested with bdevperf and bdevio for all io types.

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

abc3bc4f8e bdev/rbd: change the poller to timer poller
Poll it every 50 microseconds.
Reason: Ceph's librbd service is not very fast.
So choose a timer period to poll it, instead of
use the syscall to poll it again and again, it
is unnecessary. And this is a default value,
which can be tuned by customers later.

03b12a98b2 bdev/virtio: support event index
This fixes intermittent failures with QEMU's virtio-scsi-pci
device.

Apparently, from time to time QEMU enters a broken state in
which it doesn't turn off the NO_NOTIFY flag. This flag should
be set only for the period of time virtqueues are being processed,
but QEMU makes it set all the time. This makes us not signal any
I/O submissions - SPDK thinks the device is currently processing
notifications so it will pick up our I/O automatically, but in
realitly it won't and we end up with a deadlock.

I believe kernel virtio driver doesn't hit this issue because of
event index feature. If negotiated, the NO_NOTIFY flag won't be
used at all. Initial tests show that the issue is indeed gone
with this patch.

Event index for SPDK virtio is not particularly useful when using
a poll-mode device, but it doesn't do any harm. It can be further
optimized in the future, but macro-benchmarks don't show any
performance difference compared with the legacy notification
handling so there's no hurry.

2255533973 bdev: remove shared_resource from TAILQ before putting io channel
Normally, the put_io_channel is deferred - but for unit tests
messages are called inline and not as events.  This results
in spdk_bdev_mgmt_channel_destroy() complaining that
the shared_resource list isn't empty.

So just remove it from the TAILQ before putting the io_channel -
that's more correct anyways.

7717cfcacc bdev/iscsi: fix double spdk_bdev_module_finish_done() call
bdev_iscsi_lun_cleanup() was not accounting for LUNs
getting cleaned up before the module_finish function
was called.  This resulted in the bdev/iscsi module
calling spdk_bdev_module_finish_done twice which
resulted in io_device_unregister not found errors and
possible seg faults.

9abd8becc5 Avoid scheduling removal of the same bdev descriptor multiple times.
Deferred descriptor removal invocation under bdev_unregister() does
not account for the possibility of bdev_unregister being entered
multiple times for the same bdev (which is possible thanks to multiple
paths to unregistration - consider bdev hotremove callback and
_spdk_bdev_finish_unregister_bdevs_iter iterator - being present).
Therefore, currently nothing prevents _remove_notify for the same bdev
descriptor from being scheduled multiple times.

This commit adds boolean remove_scheduled field to struct spdk_bdev_desc.
The value is set when remove_notify for the descriptor is being
scheduled for the first time, and checked on subsequent attempts.

ed6827edbf bdev: prepopulate per-thread bdev_io cache
This helps prevent starvation in the case where a thread
is started but remains idle, while other threads consume
all of the spdk_bdev_io buffers in the global pool.

This starvation issue is fairly theoretical at this point,
but future patches will be adding the ability for callers
to be notified when an spdk_bdev_io becomes available if
the pool is exhausted.  We will add tests to stress
pool exhaustion at which point this patch will become
much more important.

While here, increase the minimum bdev_io_pool_size to
account for the mgmt_ch getting destroyed and then
immediately created again on the master core.  In this
case there is a window where both channels exist at
once - the one being destroyed won't free its cached
spdk_bdev_ios until the deferred spdk_put_io_channel
event executes.

I do not think that this variable is needed.
The rpc system will be always executed in the first
call, so there is no sync issue, add a deleted variable
and put the free in the loop sounds not very clear.

For the ASAN issue (use req after free), I think
that the correct solution is that: we should store
the context first instead of defer the free of req.

e30535fecf thread: add spdk_thread_get_count()
This will return the number of currently allocated threads.

Modify the bdev_io caching code to use this new API since these
caches are really per-thread, not per-core.  SPDK does not support
dynamic threading yet, but once it does, we will want callers to be
using functions from the thread API - not counting the number of cores
allocated to the application.

spdk_env_get_core_count may still be useful as a helper function, so
it is still kept and not deprecated.  For example, app.c uses it to
print the number of cores allocated to the application.  bdevperf should
eventually be modified to use spdk_thread_get_count, but holding off on
that for now until spdk_event_allocate() uses threads instead of a reactor
lcore to specify where the event should be executed.

a94accabff bdev: Begin encapsulating spdk_bdev_io
This begins the process of hiding data members in
spdk_bdev_io that don't need to be accessed from
within bdev modules.

One strategy would be to implement accessors for
every data member in the structure. However, that
may have negative performance effects. Instead,
create a new internal structure within the old
structure. This new structure will still be visible
for now, but at least makes clear which members
are accessible and which are not.

This patch shifts one data member to the new structure
as an example.

7f51e8e5e2 bdev/rpc: make get_bdevs_iostat name param optional
Similar to commit 75896c2510 ("bdev/rpc: make get_bdevs/config "name"
params optional"), make "name" fully optional so that specifying an
empty params object works.

2ee95af0fd bdev: stop zeroing data in spdk_bdev_get_io_stat()
This will allow multiple independent callers to request I/O statistics
without stepping on each other (previously the stats would be reset on
each request, which only works with a single caller).

This also means that we can now allow requesting stats while the VTune
integration is enabled.

Add a new function and its RPC caller. By using it, we can
get the statistics of all the bdevs or the specified bdev.

Meanwhile, with this patch, the open source tool 'sysstat/iostat'
can support for SPDK. The 'iostat' tool can call this function to
get the statistics of all the SPDK managed devices via the rpc
interface.
