fini_start() is called for each bdev module before
iterating over all unclaimed bdevs to unregister them.
This allows bdev modules to behave differently during
each such unregister. Ex. unloading lvol store when
all lvol bdevs on it are unregistered.
Another use of this callback is to unclaim all bdevs
that can be at that point. Especially ones that will
not receive callback due to no bdev registered.
Ex. offline raid bdev, when some underlying bdevs are missing.
fini_start() being synchronous does not help in cases
where to release claim on the bdev, an asynchronous operation
is required. Ex. lvol store with no bdevs present, requires
async lvs unload to be called.
This patch adds async_fini_start flag for the bdev modules,
to be used when async fini_start is required. When done,
bdev module has to call spdk_bdev_module_finish_start_done().

We had not held mutex while removing bdev name or alias from bdev
name tree for most cases. Fix these in this patch.
spdk_bdev_unregister() already holds g_bdev_mgr.mutex when removing
name, and so we do not need to change it.
spdk_bdev_close() had not held g_bdev_mgr.mutex. What we want to lock
is only when removing name from name tree, that is, calling
bdev_name_del() in bdev_unregister_unsafe(). However, we need to
keep hierarchical lock ordering. Hence get and free g_bdev_mgr.mutex
outside of bdev->internal.mutex.

spdk_bdev_register() and spdk_bdev_add_alias() had not held mutex when
adding bdev name or alias to global bdev name tree. This bug caused unexpected
error when traversing global bdev name tree.
The next patch will fix the bug. This patch is a preparation for the fix.
spdk_bdev_get_by_name() had not held mutex while traversing bdev
name tree. The major callers to spdk_bdev_get_by_name() had held mutex
when calling it. However, this was not clear.
Factor out the internal of spdk_bdev_get_by_name() into a helper
function bdev_get_by_name() and then change spdk_bdev_get_by_name()
to lock and unlock when calling bdev_get_by_name().
Then replace spdk_bdev_get_by_name() call in spdk_bdev_alias_add() and
bdev_register() by bdev_get_by_name() call.
spdk_bdev_get_by_name() call in spdk_bdev_examine() is not changed.
This is called only from JSON RPC and not related with the bug. So
we want to fix only unlocked access to global bdev name tree.

For correct behaviour, pthread_mutex should not be locked after it has
been destroyed.
g_bdev_mgr.mutex is statically initialized. It is destroyed in
bdev_mgr_unregister_cb, but not re-initialized in spdk_bdev_initialize.
Repeated calls to initialize/unregister occur during unit tests.
Remove the destroy from bdev_mgr_unregister_cb, which seems
the simplest way of resolving the issue.
The sequence: spdk_put_io_channel(), spdk_bdev_close(),
spdk_bdev_unregister() occurs during unit tests.
spdk_bdev_unregister() destroys internal.mutex which is then
locked by a call to bdev_channel_destroy() resulting from the
earlier spdk_put_io_channel(). Move the destroy and the free of
internal.qos into bdev_destroy_cb so that they don't occur until
all of the channels have been released. Remove the no longer
required bdev_fini.
Repeat calls to spdk_bdev_unregister that occur after an unregister has
completed will lock internal.mutex which has been destroyed by the
previous unregister. This occurs during unit tests. Defer locking
internal.mutex until after the internal.status has been checked for
SPDK_BDEV_STATUS_REMOVING. This is the only place where
internal.status is set to removing and g_bdev_mgr.mutex alone is
sufficient to ensure atomicity here.
Tested with a pthreads library that contains debugging code to
check the mutex state and a modified version of bdev_io_types_test
to call get_io_channel on a different thread.

To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.
Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.
Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.
This patch:
- increases SO_VER by 1 for all components

This helps user to locate whether bdev_io fails in

SPDK_BDEV_IO_STATUS_AIO_ERROR indicates bdev_io fails
due to Linux AIO or its lower layer's failure.
New functions spdk_bdev_io_complete_aio_status and
spdk_bdev_io_get_aio_status can be used to report out

"bdev_register" notification was sent right when register
happened, which was misleading for any listener.
Action on the registered bdev might not have been possible
when examine took longer time.
Order of bdev_register notifications in json_config test
was modified, because they are being sent out as pollers
for the spdk_bdev_wait_for_examine() are being processed.
This is only because pollers are inserted at the tail,
and processed from the tail as well.
Order of notifications should not matter, as long as bdevs
are ready for use.

Since user/orchestration has no chance to call
bdev_wait_for_examine when loading json configuration,
this RPC is now always built into bdev subsystem json.
This behaviour was already there for SPDK_RPC_STARTUP,
see bdev_module_action_complete().
Yet it did not apply to SPDK_RPC_RUNTIME RPCs, as the
bdev module initialization was already complete.

Add an new API spdk_bdev_part_base_construct_ext() to pass not bdev but
bdev_name to fix the race condition due to the time gap between
spdk_bdev_get_by_name() and spdk_bdev_open(). A pointer to a bdev is
valid only while the bdev is opened.
In the new API, spdk_bdev_get_by_name() is included in
spdk_bdev_part_base_construct_ext() and the caller has to know if
the bdev exists or not. Hence spdk_bdev_part_base_construct_ext()
returns return code and returns the created part object by the double
pointer.
Another critical change is that base is just freed if spdk_bdev_open_ext()
failed with -ENODEV. The reason is that if we call spdk_bdev_part_base_free()
for that case, the configuration is removed by the registered callback
and so bdev_examine() will not work.
The following patches will replace spdk_bdev_part_base_construct()
by spdk_bdev_part_base_construct_ext() for the corresponding bdev
modules.

The I/O aborted by the abort command should be completed with SC = 07h, i.e.,
"Command Abort Requested". However, if the generic bdev layer or non-NVMe
bdev module aborted the I/O, the aborted I/O would complete with SC = 06h, i.e.,
"Internal Error". To fix this unexpected behavior, add an new I/O status
SPDK_BDEV_IO_STATUS_ABORTED and update spdk_bdev_io_get_nvme_status() to
set SC to 07h if the I/O status is SPDK_BDEV_IO_STATUS_ABORTED.
If the NVMe bdev module aborts the I/O, the I/O status is set to

Add spdk_bdev_abort function as a new public API.
This goes all the way down to the bdev driver module and attempts to
abort all I/Os which has bio_cb_arg as its callback argument.
We can separate when only a single I/O has bio_cb_arg and when multiple
I/Os have bio_cb_arg, but unify both by using parent - children I/O
relationship. To avoid confusion, return matched_ios by _bdev_abort() and
store it into split_outstanding by the caller.
Exclude any I/O submitted after this abort command because the same cb_arg
may be used by all I/Os and abort may never complete.
bdev_io needs to have both bio_cb_arg and bio_to_abort because bio_cb_arg
is used to continue abort processing when it is stopped due to the capacity
of bdev_io pool, and bio_to_abort is used to pass it to the underlying
bdev module at submission. Parent I/O is not submitted directly, and is
only used in the generic bdev layer, and parent I/O's bdev_io uses bio_cb_arg.
Hence add bio_cb_arg to bdev structure and add bio_to_abort to abort structure.
In the meantime of abort operation, target I/Os may be completed. Hence
check if the target I/O still exists at completion, and set the completion
status to false only if it still exists.
Upon completion of this, i.e., this returned zero, the status
SPDK_BDEV_IO_STATUS_SUCCESS indicates all I/Os were successfully aborted,
or the status SPDK_BDEV_IO_STATUS_FAILED indicates any I/O was failed to
abort by any reason.
spdk_bdev_abort() does not support aborting abort or reset request
due to the complexity for now.
Following patches will support I/O split case.
Add unit tests together to cover the basic paths.
Besides, ABI compatibility check required us to bump up SO version of
a few libraries or modules. Bump up SO version of blob bdev module simply
because it does not have any out-of-tree consumer, and suppress bumping
up SO version of lvol library because the affected struct spdk_lvol
is not part of public APIs.

When we unlock a range, we remove the range from the
locked bdev list before doing the for_each_channel
iteration to remove the range from each channel.
But at the same time, right after removing from the
locked list, a new lock on that range could start.
In that case, we also do a for_each_channel to add
the range to each channel, and that will race with
the for_each_channel remove. When the lock start
wins, it finds the range already in the channel,
but doesn't set the owner_range which results in
a seg fault when the for_each_channel completes.
The fix is actually rather simple. We just add the
locked_ctx to the comparison when checking if the
range is already in the channel. If the locked_ctx
matches, then we know it was added as part of
initializing a new channel. If it doesn't, then
we create a new range object pointing to the new
locked_ctx. The first one will get removed when
the remove for_each_channel catches up.

So add a pending_locked_ranges to the bdev. When we

one that's already locked. If so, put it on the pending

Add an io_locked TAILQ to each channel, which hold
IO that will write to a currently locked region.
Also add a new step to the locking process per channel.
Each channel needs to wait until all existing outstanding
writes to the newly locked range have been completed.
Only the channel that locked an LBA range may submit
write I/O to it. It must use the same cb_arg for the
write I/O as the cb_arg used when locking the LBA range.
This ensures that only the specific I/O operations needing
the lock will bypass the lock.
When a range is unlocked, we will just blindly try to
resubmit all IO in the io_locked tailq. This could be
made more efficient in the future, but we don't expect
this path to occur very often, so going for simplicity
in the first pass.

manage dissemination of lock/unlock requests to all
existing channels for a given bdev. This does not
yet interact at all with any I/O sent to the channel.
Future patches will check new I/O to see if they
are trying to write to a range that is locked. Future
patches will also ensure we do not have overlapping

Previously, when additional resets were submitted while a reset was in
progress, those resets were queued and then executed serially as part of
executing the original reset. Doing multiple resets on a bdev in quick
succession is not useful if the first reset succeeds and is very
unlikely to be useful in the negative case. Instead, we should batch
resets and complete them all at once when the current reset succeeds or

Added new public header for zoned bdev. Zoned bdev is an
extension of the bdev interface. Generic concept comes
from ATA/SCSI and is also being worked as an NVMe TP.
Zoned device logical blocks space is divided into fixed-sized
zones. Each zone is described by its start logical block address
and capacity. Writes to a single zone need to be sequential.
After zone is fully written it need to be reset to write to it
again. Such writing schema could be very beneficial in terms of
write amplification factor for NAND based devices.
SPDK Flash Translation Layer library will be consuming this
interface in the future.
Extending SPDK bdev interface will allow to use existing bdev
infrastructure for this new type of devices.
Zoned device have several properties defined in spdk_bdev
structure:
- zone_size: default size of each zone
- max_open_zone: maximum number of open zones
- optimal_open_zones: optimal number of open zones to get
best performance on writes
Single zone properties are defined in spdk_bdev_zone_info
structure:
- start_lba: first logical block of z zone
- write_pointer: logical block address in the zone at
which next write shall occur.
- capacity: maximum number of logical blocks that may
be written in the zone when zone is empty.
- state: zone state
Several zone states are defined: Empty, Open, Full, Closed,
Read Only and Offline.
To change zone state zone actions are defined: Close, Finish,
Open and Reset.

The following issue was observed.
The first thread returned the last IO channel and the second thread
then removed the first base device, but raid_bdev_cleanup() was
called before raid_bdev_destroy_cb() was called.
raid_bdev_destroy_cb() was accessed to the raid bdev already freed
by raid_bdev_cleanup() and caused segmentation fault.
The call sequence was as follows:
The first thread:
spdk_put_io_channel() -> ch->destroy_cb -> raid_bdev_destroy_cb
-> access raid bdev
The second thread:
raid_bdev_remove_base_devices() -> raid_bdev_deconfigure() ->
spdk_bdev_unregister() -> spdk_io_device_unregister() ->
spdk_bdev_destroy_cb() -> raid_bdev_destruct() -> raid_bdev_cleanup()
-> free raid bdev
The fix is to hold number of created channels in struct
raid_bdev_io_channel and use it in raid_bdev_destroy_cb().
Bdev layer, IO device/channel layer, and NVMe-oF layer already
process this case correctly.

Ran into this while putting the compress tests in CI, an error
message will print following the completion of the app, checked
with Jim and it is actually not an error when lvols are involved
so change to warn now as this will show up in everyone's build
log for bdev testing.

A single I/O may allocate more than one request, since splitting may be
necessary to conform to the device's maximum transfer size, PRP list
compatibility requirements, or driver-assisted striping. Very big
I/O request sent from application may get error due to limited resources
in NVMe driver layer, so here we add an optional parameter to make the
parameter can be configured by users.
Fix issue #745.

For aarch64 spdk_mb is defined as "__asm volatile("dsb sy" ::: "memory")"
and spdk_smp_mb is defined as "__asm volatile("dmb ish" ::: "memory")".
"dsb sy" completes when all instructions before this instruction complete.
And "dmb ish" only keeps the order of memory access instructions before
and after it. It doesn't affect the ordering of any other instructions.
Here I think "dmb ish" is enough.
And replace spdk_mb with spdk_smp_mb here will not affect PPC64, X86_64
and i386.

Was 1024 but w/the performance optimizations we can now use up
to 4 mbufs per outstanding IO so going to 8192 only uses 1MB of
mem and gives us better head room before we have to start queueing
compression operations to wait for mbufs. Note: the mbuf pool is
shared accross all virtual compression bdevs.

There's a small drive-by in here also, use the max iovec define
from the reduce header instead of manually making sure its the same
here.
The change in the size of the MBUF pool is to accommodate the new
QAT driver being faster (?) than the old such that we could run out
of MBUFS with a fio test using 6 threads. On the + side, when we did
the queueing code in the compression operation worked good.
Also related to QAT and experimenting with fio compression ratios, QAT
can fairly often return an error on compression that we were treating
as an error for printing, change it to a NOTCELOG instead of an error.

Was previously creating the number of qp based on the # of cores
reported via DPDK function. Also was assigning one qp per comp_bdev.
After testing w/multiple threads in fio 2 things needed to change:
* remove use of rte core related functions as fio threads are not EAL
threads. This required choosing an upper limit for the number of
threads that the bdev module will support
* changing the qp assignment code such that comp_bdevs share the
same device_qp if on the same thread

_spdk_bdev_finish_unregister_bdevs_iter -> spdk_bdev_module_finish_iter
In abovt path, spdk_bdev_module_finish_iter will repeate to call

which never call spdk_io_device_register. It will coredump when assert false in
spdk_io_device_unregister dev is null.
To fix this, let's check whether g_bdev_mgr.module_init_complete is equals true
